Corporate venture capital (CVC) and the nanotechnology market plus 2023’s top 10 countries’ nanotechnolgy patents

I have two brief nanotechnology commercialization stories from the same publication.

Corporate venture capital (CVC) and the nano market

From a March 23, 2024 article on statnano.com, Note: Links have been removed,

Nanotechnology’s enormous potential across various sectors has long attracted the eye of investors, keen to capitalise on its commercial potency.

Yet the initial propulsion provided by traditional venture capital avenues was reined back when the reality of long development timelines, regulatory hurdles, and difficulty in translating scientific advances into commercially viable products became apparent.

While the initial flurry of activity declined in the early part of the 21st century, a new kid on the investing block has proved an enticing option beyond traditional funding methods.

Corporate venture capital has, over the last 10 years emerged as a key plank in turning ideas into commercial reality.

Simply put, corporate venture capital (CVC) has seen large corporations, recognising the strategic value of nanotechnology, establish their own VC arms to invest in promising start-ups.

The likes of Samsung, Johnson & Johnson and BASF have all sought to get an edge on their competition by sinking money into start-ups in nano and other technologies, which could deliver benefits to them in the long term.

Unlike traditional VC firms, CVCs invest with a strategic lens, aligning their investments with their core business goals. For instance, BASF’s venture capital arm, BASF Venture Capital, focuses on nanomaterials with applications in coatings, chemicals, and construction.

It has an evergreen EUR 250 million fund available and will consider everything from seed to Series B investment opportunities.

Samsung Ventures takes a similar approach, explaining: “Our major investment areas are in semiconductors, telecommunication, software, internet, bioengineering and the medical industry from start-ups to established companies that are about to be listed on the stock market.

While historically concentrated in North America and Europe, CVC activity in nanotechnology is expanding to Asia, with China being a major player.

China has, perhaps not surprisingly, seen considerable growth over the last decade in nano and few will bet against it being the primary driver of innovation over the next 10 years.

As ever, the long development cycles of emerging nano breakthroughs can frequently deter some CVCs with shorter investment horizons.

2023 Nanotechnology patent applications: which countries top the list?

A March 28, 2024 article from statnano.com provides interesting data concerning patent applications,

In 2023, a total of 18,526 nanotechnology patent applications were published at the United States Patent and Trademark Office (USPTO) and the European Patent Office (EPO). The United States accounted for approximately 40% of these nanotechnology patent publications, followed by China, South Korea, and Japan in the next positions.

According to a statistical analysis conducted by StatNano using data from the Orbit database, the USPTO published 84% of the 18,526 nanotechnology patent applications in 2023, which is more than five times the number published by the EPO. However, the EPO saw a nearly 17% increase in nanotechnology patent publications compared to the previous year, while the USPTO’s growth was around 4%.

Nanotechnology patents are defined based on the ISO/TS 18110 standard as those having at least one claim related to nanotechnology orpatents classified with an IPC classification code related to nanotechnology such as B82.

From the March 28, 2024 article,

Dealing with mosquitos: a robot story and an engineered human tissue story

I have two ‘mosquito and disease’ stories, the first concerning dengue fever and the second, malaria.

Dengue fever in Taiwan

A June 8, 2023 news item on phys.org features robotic vehicles, dengue fever, and mosquitoes,

Unmanned ground vehicles can be used to identify and eliminate the breeding sources of mosquitos that carry dengue fever in urban areas, according to a new study published in PLOS Neglected Tropical Diseases by Wei-Liang Liu of the Taiwan National Mosquito-Borne Diseases Control Research Center, and colleagues.

It turns out sewers are a problem according to this June 8, 2023 PLOS (Public Library of Science) news release on EurekAlert, provides more context and detail,

Dengue fever is an infectious disease caused by the dengue virus and spread by several mosquito species in the genus Aedes, which also spread chikungunya, yellow fever and zika. Through the process of urbanization, sewers have become easy breeding grounds for Aedes mosquitos and most current mosquito monitoring programs struggle to monitor and analyze the density of mosquitos in these hidden areas.

In the new control effort, researchers combined a crawling robot, wire-controlled cable car and real-time monitoring system into an unmanned ground vehicle system (UGV) that can take high-resolution, real-time images of areas within sewers. From May to August 2018, the system was deployed in five administrative districts in Kaohsiung city, Taiwan, with covered roadside sewer ditches suspected to be hotspots for mosquitos. Mosquito gravitraps were places above the sewers to monitor effects of the UGV intervention on adult mosquitos in the area.

In 20.7% of inspected sewers, the system found traces of Aedes mosquitos in stages from larvae to adult. In positive sewers, additional prevention control measures were carried out, using either insecticides or high-temperature water jets.  Immediately after these interventions, the gravitrap index (GI)—  a measure of the adult mosquito density nearby— dropped significantly from 0.62 to 0.19.

“The widespread use of UGVs can potentially eliminate some of the breeding sources of vector mosquitoes, thereby reducing the annual prevalence of dengue fever in Kaohsiung city,” the authors say.

Dengue on the rise

Like many diseases, dengue is one where you may not have symptoms (asymptomatic), or they’re relatively mild and can be handled at home, or you may need care in a hospital and, in some cases, it can be fatal.

The World Health Organization (WHO) notes that dengue fever cases have increased exponentially since 2000 (from the March 17, 2023 version of the WHO’s “Dengue and severe dengue” fact sheet),

Global burden

The incidence of dengue has grown dramatically around the world in recent decades, with cases reported to WHO increased from 505 430 cases in 2000 to 5.2 million in 2019. A vast majority of cases are asymptomatic or mild and self-managed, and hence the actual numbers of dengue cases are under-reported. Many cases are also misdiagnosed as other febrile illnesses (1).

One modelling estimate indicates 390 million dengue virus infections per year of which 96 million manifest clinically (2). Another study on the prevalence of dengue estimates that 3.9 billion people are at risk of infection with dengue viruses.

The disease is now endemic in more than 100 countries in the WHO Regions of Africa, the Americas, the Eastern Mediterranean, South-East Asia and the Western Pacific. The Americas, South-East Asia and Western Pacific regions are the most seriously affected, with Asia representing around 70% of the global disease burden.

Dengue is spreading to new areas including Europe, [emphasis mine] and explosive outbreaks are occurring. Local transmission was reported for the first time in France and Croatia in 2010 [emphasis mine] and imported cases were detected in 3 other European countries.

The largest number of dengue cases ever reported globally was in 2019. All regions were affected, and dengue transmission was recorded in Afghanistan for the first time. The American Region reported 3.1 million cases, with more than 25 000 classified as severe. A high number of cases were reported in Bangladesh (101 000), Malaysia (131 000) Philippines (420 000), Vietnam (320 000) in Asia.

Dengue continues to affect Brazil, Colombia, the Cook Islands, Fiji, India, Kenya, Paraguay, Peru, the Philippines, the Reunion Islands and Vietnam as of 2021. 

There’s information from an earlier version of the fact sheet, in my July 2, 2013 posting, highlighting different aspects of the disease, e.g., “About 2.5% of those affected die.”

A July 21, 2023 United Nations press release warns that the danger from mosquitoes spreading dengue fever could increase along with the temperature,

Global warming marked by higher average temperatures, precipitation and longer periods of drought, could prompt a record number of dengue infections worldwide, the World Health Organization (WHO) warned on Friday [July 21, 2023].

Despite the absence of mosquitoes infected with the dengue virus in Canada, the government has a Dengue fever information page. At this point, the concern is likely focused on travelers who’ve contracted the disease from elsewhere. However, I am guessing that researchers are keeping a close eye on Canadian mosquitoes as these situations can change.

Malaria in Florida (US)

The researchers from the University of Central Florida (UCF) couldn’t have known when they began their project to study mosquito bites and disease that Florida would register its first malaria cases in 20 years this summer, from a July 26, 2023 article by Stephanie Colombini for NPR ([US] National Public Radio), Note: Links have been removed,

First local transmission in U.S. in 20 years

Heath [Hannah Heath] is one of eight known people in recent months who have contracted malaria in the U.S., after being bitten by a local mosquito, rather than while traveling abroad. The cases comprise the nation’s first locally transmitted outbreak in 20 years. The last time this occurred was in 2003, when eight people tested positive for malaria in Palm Beach, Fla.

One of the eight cases is in Texas; the rest occurred in the northern part of Sarasota County.

The Florida Department of Health recorded the most recent case in its weekly arbovirus report for July 9-15 [2023].

For the past month, health officials have issued a mosquito-borne illness alert for residents in Sarasota and neighboring Manatee County. Mosquito management teams are working to suppress the population of the type of mosquito that carries malaria, Anopheles.

Sarasota Memorial Hospital has treated five of the county’s seven malaria patients, according to Dr. Manuel Gordillo, director of infection control.

“The cases that are coming in are classic malaria, you know they come in with fever, body aches, headaches, nausea, vomiting, diarrhea,” Gordillo said, explaining that his hospital usually treats just one or two patients a year who acquire malaria while traveling abroad in Central or South America, or Africa.

All the locally acquired cases were of Plasmodium vivax malaria, a strain that typically produces milder symptoms or can even be asymptomatic, according to the Centers for Disease Control and Prevention. But the strain can still cause death, and pregnant people and children are particularly vulnerable.

Malaria does not spread from human-to-human contact; a mosquito carrying the disease has to bite someone to transmit the parasites.

Workers with Sarasota County Mosquito Management Services have been especially busy since May 26 [2023], when the first local case was confirmed.

Like similar departments across Florida, the team is experienced in responding to small outbreaks of mosquito-borne illnesses such as West Nile virus or dengue. They have protocols for addressing travel-related cases of malaria as well, but have ramped up their efforts now that they have confirmation that transmission is occurring locally between mosquitoes and humans.

While organizations like the World Health Organization have cautioned climate change could lead to more global cases and deaths from malaria and other mosquito-borne diseases, experts say it’s too soon to tell if the local transmission seen these past two months has any connection to extreme heat or flooding.

“We don’t have any reason to think that climate change has contributed to these particular cases,” said Ben Beard, deputy director of the CDC’s US Centers for Disease Control and Prevention] division of vector-borne diseases and deputy incident manager for this year’s local malaria response.

“In a more general sense though, milder winters, earlier springs, warmer, longer summers – all of those things sort of translate into mosquitoes coming out earlier, getting their replication cycles sooner, going through those cycles faster and being out longer,” he said. And so we are concerned about the impact of climate change and environmental change in general on what we call vector-borne diseases.”.

Beard co-authored a 2019 report that highlights a significant increase in diseases spread by ticks and mosquitoes in recent decades. Lyme disease and West Nile virus were among the top five most prevalent.

“In the big picture it’s a very significant concern that we have,” he said.

Engineered tissue and bloodthirsty mosquitoes

A June 8, 2023 University of Central Florida (UCF) news release (also on EurekAlert) by Eric Eraso describes the research into engineered human tissue and features a ‘bloodthirsty’ video. First, the video,

Note: A link has been removed,

A UCF research team has engineered tissue with human cells that mosquitoes love to bite and feed upon — with the goal of helping fight deadly diseases transmitted by the biting insects.

A multidisciplinary team led by College of Medicine biomedical researcher Bradley Jay Willenberg with Mollie Jewett (UCF Burnett School of Biomedical Sciences) and Andrew Dickerson (University of Tennessee) lined 3D capillary gel biomaterials with human cells to create engineered tissue and then infused it with blood. Testing showed mosquitoes readily bite and blood feed on the constructs. Scientists hope to use this new platform to study how pathogens that mosquitoes carry impact and infect human cells and tissues. Presently, researchers rely largely upon animal models and cells cultured on flat dishes for such investigations.

Further, the new system holds great promise for blood feeding mosquito species that have proven difficult to rear and maintain as colonies in the laboratory, an important practical application. The Willenberg team’s work was published Friday in the journal Insects.

Mosquitos have often been called the world’s deadliest animal, as vector-borne illnesses, including those from mosquitos cause more than 700,000 deaths worldwide each year. Malaria, dengue, Zika virus and West Nile virus are all transmitted by mosquitos. Even for those who survive these illnesses, many are left suffering from organ failure, seizures and serious neurological impacts.

“Many people get sick with mosquito-borne illnesses every year, including in the United States. The toll of such diseases can be especially devastating for many countries around the world,” Willenberg says.

This worldwide impact of mosquito-borne disease is what drives Willenberg, whose lab employs a unique blend of biomedical engineering, biomaterials, tissue engineering, nanotechnology and vector biology to develop innovative mosquito surveillance, control and research tools. He said he hopes to adapt his new platform for application to other vectors such as ticks, which spread Lyme disease.

“We have demonstrated the initial proof-of-concept with this prototype” he says. “I think there are many potential ways to use this technology.”

Captured on video, Willenberg observed mosquitoes enthusiastically blood feeding from the engineered tissue, much as they would from a human host. This demonstration represents the achievement of a critical milestone for the technology: ensuring the tissue constructs were appetizing to the mosquitoes.

“As one of my mentors shared with me long ago, the goal of physicians and biomedical researchers is to help reduce human suffering,” he says. “So, if we can provide something that helps us learn about mosquitoes, intervene with diseases and, in some way, keep mosquitoes away from people, I think that is a positive.”

Willenberg came up with the engineered tissue idea when he learned the National Institutes of Health (NIH) was looking for new in vitro 3D models that could help study pathogens that mosquitoes and other biting arthropods carry.

“When I read about the NIH seeking these models, it got me thinking that maybe there is a way to get the mosquitoes to bite and blood feed [on the 3D models] directly,” he says. “Then I can bring in the mosquito to do the natural delivery and create a complete vector-host-pathogen interface model to study it all together.”

As this platform is still in its early stages, Willenberg wants to incorporate addition types of cells to move the system closer to human skin. He is also developing collaborations with experts that study pathogens and work with infected vectors, and is working with mosquito control organizations to see how they can use the technology.

“I have a particular vision for this platform, and am going after it. My experience too is that other good ideas and research directions will flourish when it gets into the hands of others,” he says. “At the end of the day, the collective ideas and efforts of the various research communities propel a system like ours to its full potential. So, if we can provide them tools to enable their work, while also moving ours forward at the same time, that is really exciting.”

Willenberg received his Ph.D. in biomedical engineering from the University of Florida and continued there for his postdoctoral training and then in scientist, adjunct scientist and lecturer positions. He joined the UCF College of Medicine in 2014, where he is currently an assistant professor of medicine.

Willenberg is also a co-founder, co-owner and manager of Saisijin Biotech, LLC and has a minor ownership stake in Sustained Release Technologies, Inc. Neither entity was involved in any way with the work presented in this story. Team members may also be listed as inventors on patent/patent applications that could result in royalty payments.

That final paragraph in the news release is new to me. I’ve seen them list companies where the researchers have financial interests but this is the first time I’ve seen a news release that offers a statement attempting to cover all the bases including some future possibilities such as: “Team members may also be listed as inventors on patent/patent applications that could result in royalty payments.

It seems pretty clear that there’s increasing concern about mosquito-borne diseases no matter where you live.

Toronto’s (Canada) ArtSci Salon offers: Naturalized Encounters (a series of international, networked meals known as “Follow the Spread” starting Sunday, October 3, 2021

My September 26, 2021 Art/Sci Salon notice (received via email) provides these details,

Naturalization = The ecological phenomenon in which a species, taxon, or population of exotic (as opposed to native) origin integrates into a given ecosystem, becoming capable of reproducing and growing in it, and proceeds to disseminate spontaneously. In some instances, the presence of a species in a given ecosystem is so ancient that it cannot be presupposed whether it is native or introduced
How does adaptation through naturalization occur? What happens to the native population? How does coexistence happen?

Our first event will revolve around the Solanum Melongena, a plant species in the nightshade family Solanaceae commonly known as the eggplant. This plant (and the many different names it goes by Aubergine, Melanzana, Brinjal, Berenjena, باذنجان, vânătă, 茄子,بادمجان) uncertain origins, grown worldwide for its edible fruit. Eggplants exist in many shapes, sizes and colors.

Our event will be a harvest potluck, with dialogues, storytelling, and exchanges about and beyond food. Our guests will engage in creative interventions to reflect on the many ways food, and food mobility affects all sentient beings, both humans and non-humans; peoples and civilizations; individuals’ health and collective traditions. Food is nourishment, care, medicine, and art. Food is political. Food is ultimately about our survival.

This is the first of a series of networked meals titled “FOLLOW THE SPREAD,” which will be staged around the world and across time zones throughout Fall 2021-Spring 2022 in Canada (October 3, Spring 2022), Norway (October 7), the Netherlands and Taiwan (Spring 2022).

Join us online to meet 10 Canadian artists and scholars as they launch the series in Toronto and engage in a nourishing and inspiring feast

Lurch applies her experience in community arts and education to create inviting entry points into overwhelmingly complex and urgent racial, ecological, and historical reckonings.

Lurch’s work contends with both spatiality and temporality, enchanting her subject matter with multiple possibilities for engagement. This can be seen in the interplay between light, wire, and space in her intricate wire sculptures of bees and pollen grains, and in what scholar Tiffany Lethabo King refers to as the “open edgelessness” of Sycorax. A sensuous dynamism belies the everyday tasks reflected in her charcoal-on-parchment series Being, Belonging and Grace. Lurch’s particular evocations and explorations of space and time invite an analysis of their own, and her work has been engaged with by academics. These include King, who chose Sycorax Gesture, a charcoal illustration for the cover of her book The Black Shoals: Offshore Formations of Black and Native Studies, in which King discusses Lurch’s work in depth. Scholar Katherine McKittrick both inserted and engaged with Lurch’s work in her latest notable book, Dear Science & Other Stories.

Iridescent giant clams could point the way to safety, climatologically speaking

Giant clams in Palau (Cynthia Barnett)

These don’t look like any clams I’ve ever seen but that is the point of Cynthia Barnett’s absorbing Sept. 10, 2018 article for The Atlantic (Note: A link has been removed),

Snorkeling amid the tree-tangled rock islands of Ngermid Bay in the western Pacific nation of Palau, Alison Sweeney lingers at a plunging coral ledge, photographing every giant clam she sees along a 50-meter transect. In Palau, as in few other places in the world, this means she is going to be underwater for a skin-wrinkling long time.

At least the clams are making it easy for Sweeney, a biophysicist at the University of Pennsylvania. The animals plump from their shells like painted lips, shimmering in blues, purples, greens, golds, and even electric browns. The largest are a foot across and radiate from the sea floor, but most are the smallest of the giant clams, five-inch Tridacna crocea, living higher up on the reef. Their fleshy Technicolor smiles beam in all directions from the corals and rocks of Ngermid Bay.

… Some of the corals are bleached from the conditions in Ngermid Bay, where naturally high temperatures and acidity mirror the expected effects of climate change on the global oceans. (Ngermid Bay is more commonly known as “Nikko Bay,” but traditional leaders and government officials are working to revive the indigenous name of Ngermid.)

Even those clams living on bleached corals are pulsing color, like wildflowers in a white-hot desert. Sweeney’s ponytail flows out behind her as she nears them with her camera. They startle back into their fluted shells. Like bashful fairytale creatures cursed with irresistible beauty, they cannot help but draw attention with their sparkly glow.

Barnett makes them seem magical and perhaps they are (Note: A link has been removed),

It’s the glow that drew Sweeney’s attention to giant clams, and to Palau, a tiny republic of more than 300 islands between the Philippines and Guam. Its sun-laden waters are home to seven of the world’s dozen giant-clam species, from the storied Tridacna gigas—which can weigh an estimated 550 pounds and measure over four feet across—to the elegantly fluted Tridacna squamosa. Sweeney first came to the archipelago in 2009, while working on animal iridescence as a post-doctoral fellow at the University of California at Santa Barbara. Whether shimmering from a blue morpho butterfly’s wings or a squid’s skin, iridescence is almost always associated with a visual signal—one used to attract mates or confuse predators. Giant clams’ luminosity is not such a signal. So, what is it?

In the years since, Sweeney and her colleagues have discovered that the clams’ iridescence is essentially the outer glow of a solar transformer—optimized over millions of years to run on sunlight and algal biofuel. Giant clams reach their cartoonish proportions thanks to an exceptional ability to grow their own photosynthetic algae in vertical farms spread throughout their flesh. Sweeney and other scientists think this evolved expertise may shed light on alternative fuel technologies and other industrial solutions for a warming world.

Barnett goes on to describe Palau’s relationship to the clams and the clams’ environment,

Palau’s islands have been inhabited for at least 3,400 years, and from the start, giant clams were a staple of diet, daily life, and even deity. Many of the islands’ oldest-surviving tools are crafted of thick giant-clam shell: arched-blade adzes, fishhooks, gougers, heavy taro-root pounders. Giant-clam shell makes up more than three-fourths of some of the oldest shell middens in Palau, a percentage that decreases through the centuries. Archaeologists suggest that the earliest islanders depleted the giant clams that crowded the crystalline shallows, then may have self-corrected. Ancient Palauan conservation law, known as bul, prohibited fishing during critical spawning periods, or when a species showed signs of over-harvesting.

Before the Christianity that now dominates Palauan religion sailed in on eighteenth-century mission ships, the culture’s creation lore began with a giant clam called to life in an empty sea. The clam grew bigger and bigger until it sired Latmikaik, the mother of human children, who birthed them with the help of storms and ocean currents.

The legend evokes giant clams in their larval phase, moving with the currents for their first two weeks of life. Before they can settle, the swimming larvae must find and ingest one or two photosynthetic alga, which later multiply, becoming self-replicating fuel cells. After the larvae down the alga and develop a wee shell and a foot, they kick around like undersea farmers, looking for a sunny spot for their crop. When they’ve chosen a well-lit home in a shallow lagoon or reef, they affix to the rock, their shell gaping to the sky. After the sun hits and photosynthesis begins, the microalgae will multiply to millions, or in the case of T. gigas, billions, and clam and algae will live in symbiosis for life.

Giant clam is a beloved staple in Palau and many other Pacific islands, prepared raw with lemon, simmered into coconut soup, baked into a savory pancake, or sliced and sautéed in a dozen other ways. But luxury demand for their ivory-like shells and their adductor muscle, which is coveted as high-end sashimi and an alleged aphrodisiac, has driven T. gigas extinct in China, Taiwan, and other parts of their native habitat. Some of the toughest marine-protection laws in the world, along with giant-clam aquaculture pioneered here, have helped Palau’s wild clams survive. The Palau Mariculture Demonstration Center raises hundreds of thousands of giant clams a year, supplying local clam farmers who sell to restaurants and the aquarium trade and keeping pressure off the wild population. But as other nations have wiped out their clams, Palau’s 230,000-square-mile ocean territory is an increasing target of illegal foreign fishers.

Barnett delves into how the country of Palau is responding to the voracious appetite for the giant clams and other marine life,

Palau, drawing on its ancient conservation tradition of bul, is fighting back. In 2015, President Tommy Remengesau Jr. signed into law the Palau National Marine Sanctuary Act, which prohibits fishing in 80 percent of Palau’s Exclusive Economic Zone and creates a domestic fishing area in the remaining 20 percent, set aside for local fishers selling to local markets. In 2016, the nation received a $6.6 million grant from Japan to launch a major renovation of the Palau Mariculture Demonstration Center. Now under construction at the waterfront on the southern tip of Malakal Island, the new facility will amp up clam-aquaculture research and increase giant-clam production five-fold, to more than a million seedlings a year.

Last year, Palau amended its immigration policy to require that all visitors sign a pledge to behave in an ecologically responsible manner. The pledge, stamped into passports by an immigration officer who watches you sign, is written to the island’s children:

Children of Palau, I take this pledge, as your guest, to preserve and protect your beautiful and unique island home. I vow to tread lightly, act kindly and explore mindfully. I shall not take what is not given. I shall not harm what does not harm me. The only footprints I shall leave are those that will wash away.

The pledge is winning hearts and public-relations awards. But Palau’s existential challenge is still the collective “we,” the world’s rising carbon emissions and the resulting upturns in global temperatures, sea levels, and destructive storms.

F. Umiich Sengebau, Palau’s Minister for Natural Resources, Environment, and Tourism, grew up on Koror and is full of giant-clam proverbs, wisdom and legends from his youth. He tells me a story I also heard from an elder in the state of Airai: that in old times, giant clams were known as “stormy-weather food,” the fresh staple that was easy to collect and have on hand when it was too stormy to go out fishing.

As Palau faces the storms of climate change, Sengebau sees giant clams becoming another sort of stormy-weather food, serving as a secure source of protein; a fishing livelihood; a glowing icon for tourists; and now, an inspiration for alternative energy and other low-carbon technologies. “In the old days, clams saved us,” Sengebau tells me. “I think there’s a lot of power in that, a great power and meaning in the history of clams as food, and now clams as science.”

I highly recommend Barnett’s article, which is one article in a larger series, from a November 6, 2017 The Atlantic press release,

The Atlantic is expanding the global footprint of its science writing today with a multi-year series to investigate life in all of its multitudes. The series, “Life Up Close,” created with support from Howard Hughes Medical Institute’s Department of Science Education (HHMI), begins today at TheAtlantic.com. In the first piece for the project, “The Zombie Diseases of Climate Change,” The Atlantic’s Robinson Meyer travels to Greenland to report on the potentially dangerous microbes emerging from thawing Arctic permafrost.

The project is ambitious in both scope and geographic reach, and will explore how life is adapting to our changing planet. Journalists will travel the globe to examine these changes as they happen to microbes, plants, and animals in oceans, grasslands, forests, deserts, and the icy poles. The Atlantic will question where humans should look for life next: from the Martian subsurface, to Europa’s oceans, to the atmosphere of nearby stars and beyond. “Life Up Close” will feature at least twenty reported pieces continuing through 2018.

“The Atlantic has been around for 160 years, but that’s a mere pinpoint in history when it comes to questions of life and where it started, and where we’re going,” said Ross Andersen, The Atlantic’s senior editor who oversees science, tech, and health. “The questions that this project will set out to tackle are critical; and this support will allow us to cover new territory in new and more ambitious ways.”

Getting back to the giant clams, sometimes all you can do is marvel, eh?

The reason the findings in a popular thermoelectricity paper can’t be replicated

It seems to me that over the last few years there’s been a lot more discussion about errors in science. There have always been scandals but this public interest in reproducibility of scientific results seems relatively new. In any event, a Nov. 17, 2016 news item on Nanowerk highlights research that explains why scientists have been unable to reproduce results of an influential 2014 paper (Note: A link has been removed),

A team of physicists in Clemson University’s College of Science and Academia Sinica in Taiwan has determined why other scientists have been unable to replicate a highly influential thermoelectricity study published in a prestigious, peer-reviewed journal.

In the April 2014 issue of the journal Nature (“Ultralow thermal conductivity and high thermoelectric figure of merit in SnSe crystals”), a group of scientists described an emerging crystalline material made of tin selenide that provided the highest efficiency ever recorded for thermoelectricity, the process of capturing wasted energy which is released as heat and making it available again as electricity. The paper has been viewed 45,000 times and its findings have been referenced in 600 subsequent studies, according to Google Scholar.

There appears to have been a mistake in the original research. A Nov. 17, 2016 Clemson University news release, which originated the news item, expands on the theme (Note: A link has been removed),

“If it were true, basically, they would have found a crown jewel,” said Apparao Rao, the Robert A. Bowen professor of Physics and the director of the Clemson Nanomaterials Institute.

On Nov. 3, 2016, Nature ran a brief communication by the Clemson-Sinica team explaining why the 2014 data could not be replicated.

Thermoelectricity could provide enormous monetary and environmental savings because it is sustainable; instead of requiring fuel it continually captures wasted heat energy and puts it to use. And there’s a lot of wasted energy; about 70 percent in most machines, including cars.

“When your laptop gets hot, energy is released as waste heat because it doesn’t use all the supplied electricity. Machines have limited efficiency,” according to Ramakrishna Podila, assistant professor of physics and astronomy at Clemson who co-authored the paper solving the mystery.

But, so far, the perfect material for capturing and creating thermoelectricity has proven elusive.

Heat and electrical current can flow through any material when heat is applied to one side. But to efficiently harness thermoelectricity, the material has to trap heat on one side while letting the current flow. The difference in temperature, from one side to the other, generates energy.

Imagine cookware. Expensive pots and pans are copper or they have copper cores. Copper is a great heat-conducting material: it quickly and evenly spreads heat so food cooks evenly. Copper makes for good cookware, but poor thermoelectric material.

In an ideal thermoelectric material, current-carrying electrons should flow unimpeded from the hot side to the cold side, but heat-carrying phonons, which are atomic vibrations, must be blocked, either by large atoms or defects where the material is of lower density.

Rao; Podila; Sriparna Bhattacharya, a research assistant professor in astronomy and physics; and Jian He, an associate professor in physics and astronomy at Clemson and a thermoelectrics expert, performed their own study on tin selenide in collaboration with Academia Sinica’s Institute of Physics in Taipei.

Right away, Bhattacharya noticed a problem. “The most puzzling thing was that when we measured our own tin-selenide material, we observed the same electrical flow as reported in the 2014 article, but the heat carried by the phonons was relatively higher,” Bhattacharya said.

The original research group “made tin-selenide crystal that was not fully dense,” Bhattacharya said. Ideally, a crystalline material matches its “theoretical density,” meaning it’s as dense as it can be expected to get.

“Instead of reaching 100 percent theoretical density, it reached 89 percent. A 10 percent difference might not seem like much,” she said, but it can have a huge implication on the electron and phonon flow.

The Clemson-Taiwan collaborators are now focusing on their own assessment of thermoelectricity in tin-selenide. They expect to publish soon.

You can check for more information and deadlines in the Nanotechnology Now Oct. 10, 2016 news item.

The Graphene Malalysia 2016 conference website can be found here and Malaysia’s National Graphene Action Plan 2020, which is well written, can be found here (PDF).  This portion from the executive summary offers some insight into Malyasia’s plans to launch itself into the world of high income nations,

Malaysia’s aspiration to become a high-income nation by 2020 with improved jobs and better outputs is driving the country’s shift away from “business as usual,” and towards more innovative and high value add products. Within this context, and in accordance with National policies and guidelines, Graphene, an emerging, highly versatile carbon-based nanomaterial, presents a unique opportunity for Malaysia to develop a high value economic ecosystem within its industries.  Isolated only in 2004, Graphene’s superior physical properties such as electrical/ thermal conductivity, high strength and high optical transparency, combined with its manufacturability have raised tremendous possibilities for its application across several functions and make it highly interesting for several applications and industries.  Currently, Graphene is still early in its development cycle, affording Malaysian companies time to develop their own applications instead of relying on international intellectual property and licenses.

Considering the potential, several leading countries are investing heavily in associated R&D. Approaches to Graphene research range from an expansive R&D focus (e.g., U.S. and the EU) to more focused approaches aimed at enhancing specific downstream applications with Graphene (e.g., South Korea). Faced with the need to push forward a multitude of development priorities, Malaysia must be targeted in its efforts to capture Graphene’s potential, both in terms of “how to compete” and “where to compete”. This National Graphene Action Plan 2020 lays out a set of priority applications that will be beneficial to the country as a whole and what the government will do to support these efforts.

Globally, much of the Graphene-related commercial innovation to date has been upstream, with producers developing techniques to manufacture Graphene at scale. There has also been some development in downstream sectors, as companies like Samsung, Bayer MaterialScience, BASF and Siemens explore product enhancement with Graphene in lithium-ion battery anodes and flexible displays, and specialty plastic and rubber composites. However the speed of development has been uneven, offering Malaysian industries willing to invest in innovation an opportunity to capture the value at stake. Since any innovation action plan has to be tailored to the needs and ambitions of local industry, Malaysia will focus its Graphene action plan initially on larger domestic industries (e.g., rubber) and areas already being targeted by the government for innovation such as energy storage for electric vehicles and conductive inks.

In addition to benefiting from the physical properties of Graphene, Malaysian downstream application providers may also capture the benefits of a modest input cost advantage for the domestic production of Graphene.  One commonly used Graphene manufacturing technique, the chemical vapour deposition (CVD) production method, requires methane as an input, which can be sourced economically from local biomass. While Graphene is available commercially from various producers around the world, downstream players may be able to enjoy some cost advantage from local Graphene supply. In addition, co-locating with a local producer for joint product development has the added benefit of speeding up the R&D lifecycle.

That business about finding downstream applications could also to the Canadian situation where we typically offer our resources (upstream) but don’t have an active downstream business focus. For example, we have graphite mines in Ontario and Québec which supply graphite flakes for graphene production which is all upstream. Less well developed are any plans for Canadian downstream applications.

Finally, it was interesting to note that the Phantoms Foundation is organizing this Malaysian conference since the same organization is organizing the ‘2nd edition of Graphene & 2D Materials Canada 2016 International Conference & Exhibition’ (you can find out more about the Oct. 18 – 20, 2016 event in my Sept. 23, 2016 posting). I think the Malaysians have a better title for their conference, far less unwieldy.

Nanotechnology theft in Taiwan

Charges are being laid against five men in Taiwan for theft of intellectual property from a nanotechnology firm according to a July 28, 2016 news item on the http://www.vidalatinasd.com website,

Five former employees of a Taiwanese nanotechnology firm have been charged with violating trade secrets laws by stealing technology and taking it to China, the National Police Agency said Thursday [July 28, 2016].

The accused are three former employees of Hsin Fang Nano Technology, including a production section chief surnamed Yu and a plant manager surnamed Chen, along with two other business associates.

A July 28, 2016 news article by Jason Pan for Taipei Times offers more detail,

“The estimated financial loss to our company is about NT$2.6 billion [US$81.08 million]. We urge the government to crack down on intellectual property theft against Taiwanese businesses,” chairman Chang Jen-hung (張仁鴻) said.

Hsin Fang is a grinding mill machine manufacturer, which are used to produce ultra-fine nanopowders for use in pharmaceuticals, cosmetics, consumer electronics, health food, anti-radiation coating, military weapons and in other industrial applications.

Company officials said their nanopowder grinding mill, which incorporates an innovative “dry cryo-nanonization grinding system,” received a top award at a nanotechnology exhibition in Tokyo in 2012, and honors at other industry fairs in Taiwan and other countries.

The investigation in 2014 followed reports that Chen, Yu and other former employees, backed by business associates, started a new company in Yunlin County — Unicat Nano Advanced Materials & Devices Technology Co (環美凱特).

Unicat Nano later moved to Chongqing, China, setting up nanotechnology businesses that, according to investigators, were based on intellectual property stolen from Hsin Fang by Chen, Yu and other former employees.

This is the first alleged intellectual property crime regarding nanotechnology that I’ve covered here. The crimes I’ve usually covered are bombings (Mexico) or attempted bombings (Switzerland) as someone violently protests the technology.

Nanotechnology and vinyl records

A Taipei Times April 17, 2016 article by Chang Chung-yi and Jake Chung announces,

… a recent technological breakthrough in the production of vinyl records might lead to a resurgence in their popularity, especially for audiophiles.

The Taiwan branch of Japanese company Ulvac unveiled samples of its vinyl records — coated in nano-scale molybdenum — at the Hi-End Audio Show in Kaohsiung that opened on Thursday and is to run through today, with more than 200 international brands displaying products at its 80 stalls.

Ulvac demonstrated the technology’s ability to fix common problems that plague vinyl records, such as scratching, poor heat conductivity and susceptibility to static electricity.

Ulvac staff said that the coating helps harden the polyvinyl chloride (PVC) material that records are made of and prevents it from being easily damaged, adding that the coating also allows for more refined sound quality.

Local media reported that the coating was developed by Ulvac Taiwan vice chief executive officer Clare Wei (魏雲祥), who started listening to vinyl records last year.

After discovering the problems associated with the PVC used in the production of records, Wei spent more than NT$150 million (US$4.64 million) on laboratories, equipment and personnel to try to apply the nano-scale coating material on vinyl, the Chinese-language United Daily News reported.

According to one expert, the technology for producing records hadn’t changed since the 1940’s.

Tempest in a teapot or a sign of things to come? UK’s National Graphene Institute kerfuffle

A scandal-in-the-offing, intellectual property, miffed academics, a chortling businessman, graphene, and much more make this a fascinating story.

Before launching into the main attractions, those unfamiliar with the UK graphene effort might find this background informal useful. Graphene, was first isolated at the University of Manchester in 2004 by scientists Andre Geim* and Konstantin Novoselov, Russian immigrants, both of whom have since become Nobel laureates and knights of the realm. The excitement in the UK and elsewhere is due to graphene’s extraordinary properties which could lead to transparent electronics, foldable/bendable electronics, better implants, efficient and inexpensive (they hope) water filters, and more. The UK government has invested a lot of money in graphene as has the European Union (1B Euros in the Graphene Flagship) in the hope that huge economic benefits will be reaped.

Dexter Johnson’s March 15, 2016 posting on his Nanoclast blog (on the IEEE [Institute for Electrical and Electronics Engineers] website) provides details about the situation (Note: Links have been removed),

A technology that, a year ago, was being lauded as the “first commercially viable consumer product” using graphene now appears to be caught up in an imbroglio over who owns its intellectual property rights. The resulting controversy has left the research institute behind the technology in a bit of a public relations quagmire.

The venerable UK publication The Sunday Times reported this week on what appeared to be a mutiny occurring at the National Graphene Institute (NGI) located at the University of Manchester. Researchers at the NGI had reportedly stayed away from working at the institute’s gleaming new $71 million research facility over fears that their research was going to end up in the hands of foreign companies, in particular a Taiwan-based company called BGT Materials.

The “first commercially viable consumer product” noted in Dexter’s posting was a graphene-based lightbulb which was announced by the NGI to much loud crowing in March 2015 (see my March 30, 2015 posting). The company producing the lightbulb was announced as “… Graphene Lighting PLC is a spin-out based on a strategic partnership with the National Graphene Institute (NGI) at The University of Manchester to create graphene applications.” There was no mention of BGT.

Dexter describes the situation from the BGT perspective (from his March 15, 2016 posting), Note: Links have been removed,

… BGT did not demur when asked by  the Times whether it owned the technology. In fact, Chung Ping Lai, BGT’s CEO, claimed it was his company that had invented the technology for the light bulb and not the NGI. The Times report further stated that Lai controls all the key patents and claims to be delighted with his joint venture with the university. “I believe in luck and I have had luck in Manchester,” Lai told the Times.

With companies outside the UK holding majority stakes in the companies spun out of the NGI—allowing them to claim ownership of the technologies developed at the institute—one is left to wonder what was the purpose of the £50 million (US $79 million) earmarked for graphene research in the UK more than four years ago? Was it to develop a local economy based around graphene—a “Graphene Valley”, if you will? Or was it to prop up the local construction industry through the building of shiny new buildings that reportedly few people occupy? That’s the charge leveled by Andre Geim, Nobel laureate for his discovery of graphene, and NGI’s shining star. Geim reportedly described the new NGI building as: “Money put in the British building industry rather than science.”

Dexter ends his March 15, 2016 posting with an observation  that will seem familiar to Canadians,

Now, it seems the government’s eagerness to invest in graphene research—or at least, the facilities for conducting that research—might have ended up bringing it to the same place as its previous lack of investment: the science is done in the UK and the exploitation of the technology is done elsewhere.

The March 13, 2016 Sunday Times article [ETA on April 3, 2016: This article is now behind a paywall] by Tom Harper, Jon Ungoed-Thomas and Michael Sheridan, which seems to be the source of Dexter’s posting, takes a more partisan approach,

ACADEMICS are boycotting a top research facility after a company linked to China was given access to lucrative confidential material from one of Britain’s greatest scientific breakthroughs.

Some scientists at Manchester University working on graphene, a wonder substance 200 times stronger than steel, refuse to work at the new £61m national institution, set up to find ways to exploit the material, amid concerns over a deal struck between senior university management and BGT Materials.

The academics are concerned that the National Graphene Institute (NGI), which was opened last year by George Osborne, the chancellor, and forms one of the key planks of his “northern powerhouse” industrial strategy, does not have the necessary safeguards to protect their confidential research, which could revolutionise the electronics, energy, health and building industries.

BGT, which is controlled by a Taiwanese businessman, subsequently agreed to work with a Chinese manufacturing company and university to develop similar graphene technology.

BGT says its work in Manchester has been successful and it is “offensive” and “untrue” to suggest that it would unfairly use intellectual property. The university say there is no evidence “whatsoever” of unfair use of confidential information. Manchester says it is understandable that some scientists are cautious about the collaborative environment of the new institute. But one senior academic said the arrangement with BGT had caused the university’s graphene research to descend into “complete anarchy”.

The academic said: “The NGI is a national facility, and why should we use it for a company, which is not even an English [owned] company? How much [intellectual property] is staying in England and how much is going to Taiwan?”

The row highlights concerns that the UK has dawdled in developing one of its greatest discoveries. Nearly 50% of ­graphene-related patents have been filed in China, and just 1% in Britain.

Manchester signed a £5m “research collaboration agreement” with BGT Materials in October 2013. Although the company is controlled by a Taiwanese businessman, Chung-ping Lai, the university does have a 17.5% shareholding.

Manchester claimed that the commercial deal would “attract a significant number of jobs to the city” and “benefit the UK economy”.

However, an investigation by The Sunday Times has established:

Only four jobs have been created as a result of the deal and BGT has not paid the full £5m due under the agreement after two projects were cancelled.

Pictures sent to The Sunday Times by a source at the university last month show that the offices at the NGI [National Graphene Institute], which can accommodate 120 staff, were deserted.

British-based businessmen working with graphene have also told The Sunday Times of their concerns about the institute’s information security. Tim Harper, a Manchester-based graphene entrepreneur, said: “We looked at locating there [at the NGI] but we take intellectual property extremely seriously and it is a problem locating in such a facility.

“If you don’t have control over your computer systems or the keys to your lab, then you’ve got a problem.”

I recommend reading Dexter’s post and the Sunday Times article as they provide some compelling insight into the UK situation vis à vis nanotechnology, science, and innovation.

Global overview of nano-enabled food and agriculture regulation

First off, this post features an open access paper summarizing global regulation of nanotechnology in agriculture and food production. From a Sept. 11, 2015 news item on Nanowerk,

An overview of regulatory solutions worldwide on the use of nanotechnology in food and feed production shows a differing approach: only the EU and Switzerland have nano-specific provisions incorporated in existing legislation, whereas other countries count on non-legally binding guidance and standards for industry. Collaboration among countries across the globe is required to share information and ensure protection for people and the environment, according to the paper …

A Sept. 11, 2015 European Commission Joint Research Centre press release (also on EurekAlert*), which originated the news item, summarizes the paper in more detail (Note: Links have been removed),

The paper “Regulatory aspects of nanotechnology in the agri/feed/food sector in EU and non-EU countries” reviews how potential risks or the safety of nanotechnology are managed in different countries around the world and recognises that this may have implication on the international market of nano-enabled agricultural and food products.

Nanotechnology offers substantial prospects for the development of innovative products and applications in many industrial sectors, including agricultural production, animal feed and treatment, food processing and food contact materials. While some applications are already marketed, many other nano-enabled products are currently under research and development, and may enter the market in the near future. Expected benefits of such products include increased efficacy of agrochemicals through nano-encapsulation, enhanced bioavailability of nutrients or more secure packaging material through microbial nanoparticles.

As with any other regulated product, applicants applying for market approval have to demonstrate the safe use of such new products without posing undue safety risks to the consumer and the environment. Some countries have been more active than others in examining the appropriateness of their regulatory frameworks for dealing with the safety of nanotechnologies. As a consequence, different approaches have been adopted in regulating nano-based products in the agri/feed/food sector.

The analysis shows that the EU along with Switzerland are the only ones which have introduced binding nanomaterial definitions and/or specific provisions for some nanotechnology applications. An example would be the EU labelling requirements for food ingredients in the form of ‘engineered nanomaterials’. Other regions in the world regulate nanomaterials more implicitly mainly by building on non-legally binding guidance and standards for industry.

The overview of existing legislation and guidances published as an open access article in the Journal Regulatory Toxicology and Pharmacology is based on information gathered by the JRC, RIKILT-Wageningen and the European Food Safety Agency (EFSA) through literature research and a dedicated survey.

Here’s a link to and a citation for the paper,

Regulatory aspects of nanotechnology in the agri/feed/food sector in EU and non-EU countries by Valeria Amenta, Karin Aschberger, , Maria Arena, Hans Bouwmeester, Filipa Botelho Moniz, Puck Brandhoff, Stefania Gottardo, Hans J.P. Marvin, Agnieszka Mech, Laia Quiros Pesudo, Hubert Rauscher, Reinhilde Schoonjans, Maria Vittoria Vettori, Stefan Weigel, Ruud J. Peters. Regulatory Toxicology and Pharmacology Volume 73, Issue 1, October 2015, Pages 463–476 doi:10.1016/j.yrtph.2015.06.016

This is the most inclusive overview I’ve seen yet. The authors cover Asian countries, South America, Africa, and the MIddle East, as well as, the usual suspects in Europe and North America.

Given I’m a Canadian blogger I feel obliged to include their summary of the Canadian situation (Note: Links have been removed),

4.2. Canada

The Canadian Food Inspection Agency (CFIA) and Public Health Agency of Canada (PHAC), who have recently joined the Health Portfolio of Health Canada, are responsible for food regulation in Canada. No specific regulation for nanotechnology-based food products is available but such products are regulated under the existing legislative and regulatory frameworks.11 In October 2011 Health Canada published a “Policy Statement on Health Canada’s Working Definition for Nanomaterials” (Health Canada, 2011), the document provides a (working) definition of NM which is focused, similarly to the US definition, on the nanoscale dimensions, or on the nanoscale properties/phenomena of the material (see Annex I). For what concerns general chemicals regulation in Canada, the New Substances (NS) program must ensure that new substances, including substances that are at the nano-scale (i.e. NMs), are assessed in order to determine their toxicological profile ( Environment Canada, 2014). The approach applied involves a pre-manufacture and pre-import notification and assessment process. In 2014, the New Substances program published a guidance aimed at increasing clarity on which NMs are subject to assessment in Canada ( Environment Canada, 2014).

Canadian and US regulatory agencies are working towards harmonising the regulatory approaches for NMs under the US-Canada Regulatory Cooperation Council (RCC) Nanotechnology Initiative.12 Canada and the US recently published a Joint Forward Plan where findings and lessons learnt from the RCC Nanotechnology Initiative are discussed (Canada–United States Regulatory Cooperation Council (RCC) 2014).

Based on their summary of the Canadian situation, with which I am familiar, they’ve done a good job of summarizing. Here are a few of the countries whose regulatory instruments have not been mentioned here before (Note: Links have been removed),

In Turkey a national or regional policy for the responsible development of nanotechnology is under development (OECD, 2013b). Nanotechnology is considered as a strategic technological field and at present 32 nanotechnology research centres are working in this field. Turkey participates as an observer in the EFSA Nano Network (Section 3.6) along with other EU candidate countries Former Yugoslav Republic of Macedonia, and Montenegro (EFSA, 2012). The Inventory and Control of Chemicals Regulation entered into force in Turkey in 2008, which represents a scale-down version of the REACH Regulation (Bergeson et al. 2010). Moreover, the Ministry of Environment and Urban Planning published a Turkish version of CLP Regulation (known as SEA in Turkish) to enter into force as of 1st June 2016 (Intertek).

The Russian legislation on food safety is based on regulatory documents such as the Sanitary Rules and Regulations (“SanPiN”), but also on national standards (known as “GOST”) and technical regulations (Office of Agricultural Affairs of the USDA, 2009).
