TRIUMF accelerator used by US researchers to visualize properties of nanoscale materials

The US researchers are at the University of California at Los Angeles (UCLA) and while it’s not explicitly stated I’m assuming the accelerator they mention at TRIUMF (Canada’s national laboratory for particle and nuclear physics) has something special as there are accelerators in California and other parts of the US.

A July 15, 2015 news item on Nanotechnology Now announces the latest on visualizing the properties of nanoscale materials,

Scientists trying to improve the semiconductors that power our electronic devices have focused on a technology called spintronics as one especially promising area of research. Unlike conventional devices that use electrons’ charge to create power, spintronic devices use electrons’ spin. The technology is already used in computer hard drives and many other applications — and scientists believe it could eventually be used for quantum computers, a new generation of machines that use quantum mechanics to solve complex problems with extraordinary speed.

A July 15, 2015 UCLA news release, which originated the news item, expands on the theme and briefly mentions TRIUMF’s accelerator (Note: A link has been removed),

Emerging research has shown that one key to greatly improving performance in spintronics could be a class of materials called topological insulators. Unlike ordinary materials that are either insulators or conductors, topological insulators function as both simultaneously — on the inside, they are insulators but on their exteriors, they conduct electricity.

But topological insulators have certain defects that have so far limited their use in practical applications, and because they are so tiny, scientists have so far been unable to fully understand how the defects impact their functionality.

The UCLA researchers have overcome that challenge with a new method to visualize topological insulators at the nanoscale. An article highlighting the research, which was which led by Louis Bouchard, assistant professor of chemistry and biochemistry, and Dimitrios Koumoulis, a UCLA postdoctoral scholar, was published online in the Proceedings of the National Academy of Sciences.

The new method is the first use of beta‑detected nuclear magnetic resonance to study the effects of these defects on the properties of topological insulators.

The technique involves aiming a highly focused stream of ions at the topological insulator. To generate that beam of ions, the researchers used a large particle accelerator called a cyclotron, which accelerates protons through a spiral path inside the machine and forces them to collide with a target made of the chemical element tantalum. This collision produces lithium-8 atoms, which are ionized and slowed down to a desired energy level before they are implanted in the topological insulators.

In beta‑detected nuclear magnetic resonance, ions (in this case, the ionized lithium-8 atoms) of various energies are implanted in the material of interest (the topological insulator) to generate signals from the material’s layers of interest.

Bouchard said the method is particularly well suited for probing regions near the surfaces and interfaces of different materials.

In the UCLA research, the high sensitivity of the beta‑detected nuclear magnetic resonance technique and its ability to probe materials allowed the scientists to “see” the impacts of the defects in the topological insulators by viewing the electronic and magnetic properties beneath the surface of the material.

The researchers used the large TRIUMF cyclotron in Vancouver, British Columbia.

According to the UCLA news release, there were also researchers from the University of British Columbia, the University of Texas at Austin and Northwestern University involved with the work.

Yarns of niobium nanowire for small electronic device boost at the University of British Columbia (Canada) and Massachusetts Institute of Technology (US)

It turns out that this research concerning supercapacitors is a collaboration between the University of British Columbia (Canada) and the Massachusetts Institute of Technology (MIT). From a July 7, 2015 news item by Stuart Milne for Azonano,

A team of researchers from MIT and University of British Columbia has discovered an innovative method to deliver short bursts of high power required by wearable electronic devices.

Such devices are used for monitoring health and fitness and as such are rapidly growing in the consumer electronics industry. However, a major drawback of these devices is that they are integrated with small batteries, which fail to deliver sufficient amount of power required for data transmission.

According to the research team, one way to resolve this issue is to develop supercapacitors, which are capable of storing and releasing short bursts of electrical power required to transmit data from smartphones, computers, heart-rate monitors, and other wearable devices. supercapacitors can also prove useful for other applications where short bursts of high power is required, for instance autonomous microrobots.

A July 7, 2015 MIT news release provides more detail about the research,

The new approach uses yarns, made from nanowires of the element niobium, as the electrodes in tiny supercapacitors (which are essentially pairs of electrically conducting fibers with an insulator between). The concept is described in a paper in the journal ACS Applied Materials and Interfaces by MIT professor of mechanical engineering Ian W. Hunter, doctoral student Seyed M. Mirvakili, and three others at the University of British Columbia.

Nanotechnology researchers have been working to increase the performance of supercapacitors for the past decade. Among nanomaterials, carbon-based nanoparticles — such as carbon nanotubes and graphene — have shown promising results, but they suffer from relatively low electrical conductivity, Mirvakili says.

In this new work, he and his colleagues have shown that desirable characteristics for such devices, such as high power density, are not unique to carbon-based nanoparticles, and that niobium nanowire yarn is a promising an alternative.

“Imagine you’ve got some kind of wearable health-monitoring system,” Hunter says, “and it needs to broadcast data, for example using Wi-Fi, over a long distance.” At the moment, the coin-sized batteries used in many small electronic devices have very limited ability to deliver a lot of power at once, which is what such data transmissions need.

“Long-distance Wi-Fi requires a fair amount of power,” says Hunter, the George N. Hatsopoulos Professor in Thermodynamics in MIT’s Department of Mechanical Engineering, “but it may not be needed for very long.” Small batteries are generally poorly suited for such power needs, he adds.

“We know it’s a problem experienced by a number of companies in the health-monitoring or exercise-monitoring space. So an alternative is to go to a combination of a battery and a capacitor,” Hunter says: the battery for long-term, low-power functions, and the capacitor for short bursts of high power. Such a combination should be able to either increase the range of the device, or — perhaps more important in the marketplace — to significantly reduce size requirements.

The new nanowire-based supercapacitor exceeds the performance of existing batteries, while occupying a very small volume. “If you’ve got an Apple Watch and I shave 30 percent off the mass, you may not even notice,” Hunter says. “But if you reduce the volume by 30 percent, that would be a big deal,” he says: Consumers are very sensitive to the size of wearable devices.

The innovation is especially significant for small devices, Hunter says, because other energy-storage technologies — such as fuel cells, batteries, and flywheels — tend to be less efficient, or simply too complex to be practical when reduced to very small sizes. “We are in a sweet spot,” he says, with a technology that can deliver big bursts of power from a very small device.

Ideally, Hunter says, it would be desirable to have a high volumetric power density (the amount of power stored in a given volume) and high volumetric energy density (the amount of energy in a given volume). “Nobody’s figured out how to do that,” he says. However, with the new device, “We have fairly high volumetric power density, medium energy density, and a low cost,” a combination that could be well suited for many applications.

Niobium is a fairly abundant and widely used material, Mirvakili says, so the whole system should be inexpensive and easy to produce. “The fabrication cost is cheap,” he says. Other groups have made similar supercapacitors using carbon nanotubes or other materials, but the niobium yarns are stronger and 100 times more conductive. Overall, niobium-based supercapacitors can store up to five times as much power in a given volume as carbon nanotube versions.

Niobium also has a very high melting point — nearly 2,500 degrees Celsius — so devices made from these nanowires could potentially be suitable for use in high-temperature applications.

In addition, the material is highly flexible and could be woven into fabrics, enabling wearable forms; individual niobium nanowires are just 140 nanometers in diameter — 140 billionths of a meter across, or about one-thousandth the width of a human hair.

So far, the material has been produced only in lab-scale devices. The next step, already under way, is to figure out how to design a practical, easily manufactured version, the researchers say.

“The work is very significant in the development of smart fabrics and future wearable technologies,” says Geoff Spinks, a professor of engineering at the University of Wollongong, in Australia, who was not associated with this research. This paper, he adds, “convincingly demonstrates the impressive performance of niobium-based fiber supercapacitors.”

Café Scientifique (Vancouver, Canada) makes a ‘happy’ change: new speaker for April 28, 2015

For the first time since I’ve started posting about Vancouver’s Café Scientifique there’s been a last minute change of speakers. It’s due to an addition to Dr. Kramer’s family. Congratulations!

So, Tuesday, April 28, 2015’s  Café Scientifique, held in the back room of The Railway Club (2nd floor of 579 Dunsmuir St. [at Seymour St.], will be hosting a talk from a different speaker and on a different topic,

Ph.D candidate and Vanier Scholar, Kostadin Kushlev from the Department of Psychology at UBC presenting his exciting research. Details are as follows:

Always Connected: How Smartphones May be Disconnecting Us From the People Around Us.

Smartphones have transformed where and how we access information and connect with our family and friends. But how might these powerful pocket computers be affecting how and when we interact with others in person? In this talk, I will present recent data from our lab suggesting that smartphones can compromise how connected we feel to close others, peers, and strangers. Parents spending time with their children felt more distracted and less socially connected when they used their phones a lot. Peers waiting together for an appointment connected with each other less and felt less happy when they had access to their phones as compared to when they did not. And, people looking for directions trusted members of their community less when they relied on their phones for directions rather than on the kindness of strangers. These findings highlight some of the perils of being constantly connected for our nonvirtual social lives and for the social fabric of society more generally.

On looking up the speaker online, I found that the main focus of his research is happiness, from the University of British Columbia’s (UBC) Graduate and PostGraduate webpage for Kostadin Kushlev,

 Research topic: Happiness and well-being
Research group: Social Cognition and Emotion Lab
Research location: UBC Vancouver, Kenny Building, 2136 West Mall
Research supervisor: Elizabeth Dunn

Research description
My research focuses on the emotional experience of people. The topics that I am currently investigating range from what gives (or takes away from) people’s experience of meaning in life to how people react to shame and guilt, and to what extent new technologies introduce stress and anxiety in our lives.

Home town: Madan
Country: Bulgaria

Given that the United Nations’ 2015 World Happiness Report (co-authored by UBC professor emeritus John Helliwell) was released on April 23, 2015,  the same day that the Museum of Vancouver’s The Happy Show (Stefan Sagmeister: The Happy Show) opened, Kostadin Kushlev seems like a ‘happy’ choice for a substitute speaker just days later on April 28, 2015, especially since the original topic was ‘pain’.

Tune in, turn on, and drop out—LSD and psychedelic talk at Vancouver’s (Canada) Café Scientifique on March 31, 2015

There seems to be a lot of interest in psychedelics these days and not least here in Vancouver. Next Tuesday, March 31, 2015 Cafe Scientifique, held in the back room of The Railway Club (2nd floor of 579 Dunsmuir St. [at Seymour St.], will be hosting a talk on LSD (from the March 16, 2015 announcement,

Our speaker for the evening will be Dr. Michael Hughesa Research Associate in the Department of Medical Genetics at UBC (University of British Columbia) …

Psychedelic Medicine: The History & Science of LSD in the Clinic

Ergot is a fungus that grows on rye and other grains that has been blamed (rightly or wrongly) for episodes of mass hysteria throughout history. Lysergic acid diethylamide (LSD) was first synthesized from ergot in 1938 by a Swiss chemist named Albert Hoffman, who, at the height of World War II, also discovered (somewhat mysteriously) its psychedelic properties. LSD soon came to the attention of the U.S. Army who quickly proceeds to buy up all the supply – primarily to keep it out of the hands of its enemies. Throughout the Cold War, elements in U.S. defense and security agencies engage in experiments by secretly slipping LSD to citizens with dangerous (and sometimes comical) consequences with the goal of perfecting brainwashing and mind control. Canadian scientists at McGill participated in some of these studies, thinking they could use LSD to cure psychoses. These unethical and largely unscientific experiments were akin to psychological torture. Meanwhile, the public discovered the recreational benefits of LSD and the hippie movement adopted the drug as a symbol and vehicle to enlightenment. Largely for this reason, in the early ‘70s LSD was classified as a Schedule-1 drug in the U.S. restricted legal access stopped most research and hopes of the clinical benefits of LSD was abandoned and all but forgotten. Recently, scientists, mostly working outside of the U.S. and Canada, have rediscovered LSD’s efficacy for the treatment of psychiatric disorders including post-traumatic stress syndrome (PTSD) and existential fear in terminally ill patients. Are we ready for a new wave of ethical human research to (re)-discover the clinical benefits of LSD? Take a journey through the strange history of LSD research and learn about its potential applications in medicine. What a long, strange trip it’s been.

Hughes works as a team member in the Hematopoietic Cell Development laboratory at the University of British Columbia’s (UBC) Biomedical Research Centre.

Last week on March 18, 2015, The UBC Neuroscience Graduate Student Association hosted a screening of Neurons to Nirvana: Understanding Psychedelic Medicines at the Pacific Cinematheque theatre in Vancouver (Note: Links have been removed),

A thought-provoking and visually-stunning documentary that explores the potential of five powerful psychedelic substances (LSD, psilocybin, MDMA, ayahuasca, and cannabis) as psychotherapeutic medicines. Despite the potential promise shown by such drugs in research conducted in the 1950s, the increasingly restrictive anti-drug policies of successive governments effectively shut down further enquiry. As one of the many world-renowned researchers, writers, psychologists, and scientists interviewed in the film says: “The government does not allow this research to take place, and then says there’s no research to support it. It’s beyond hypocrisy.” The film is a cogent call to put irrational, fear-based beliefs aside in order to allow clinical, evidence-based research into psychedelics in areas such as addictions, PTSD, anxiety, depression, and end-of-life care.

Post-screening discussion with co-director Oliver Hockenhull and Mark Haden.

A teacher and essayist as well as a filmmaker, Oliver Hockenhull has presented at numerous universities in Canada, the US, and Europe. He has blended the documentary, essay, and experimental genres in such previous works as Aldous Huxley: The Gravity of Light (1996), Building Heaven, Remembering Earth (1999), and Evo (2002).

Mark Haden worked for Vancouver Coastal Health Addiction Services for 28 years and is now an Adjunct Professor at the UBC School of Population and Public Health. He is a pivotal voice in the drug policy reform movement, providing viable models for reforming drug education and regulating markets for currently illegal substances. Mark is also the Chair of the Board of MAPS Canada (Multidisciplinary Association for Psychedelic Studies).

Moderated by Dr. Harry Karlinsky, Clinical Professor, Department of Psychiatry, University of British Columbia.

Perhaps popular demand will lead to another showing. In the meantime, there’s Hughes’ talk and if his description is indicative it should be fascinating.

For anyone who did not recognize it,  ‘tune in, turn on, and drop out’, is a phrase that Timothy Leary, the high priest of psychedelics, psychologist, and former lecturer at Harvard University popularized during the 1960s and 70s. According to the ‘tune in, turn on, and drop out‘ entry in Wikipedia, the phrase was given to Leary by Canadian media theorist, Marshall McLuhan.

ETA March 27, 2015 at 1610 PDT: I just received a newsletter from Canada’s National Film Board where the feature item is this,

All About Acid: Hofmann’s Potion

Open your mind with this powerful feature documentary that retraces the history of LSD, a substance first used to treat addiction and mental illness that became the self-understanding tool of a generation.

The secret life of leaves at Vancouver’s (Canada) Café Scientifique on Jan. 27, 2015

Vancouver’s next Café Scientifique is being held in the back room of the The Railway Club (2nd floor of 579 Dunsmuir St. [at Seymour St.], Vancouver, Canada), on Jan. 27,  2015*. Here’s the meeting description (from the Jan. 19, 2015 announcement),

Happy New Year!  We hope you all had an enjoyable and relaxing holiday season.  We’d like to send out a big thank you for your generosity in our crowdfunding campaign and your help in its promotion.  Your donations and support will help to keep us running for another year and more!

Speaking of which, our next café will happen on Tuesday, January 27th, at 7:30pm at The Railway Club. Our speaker for the evening will be Dr. Chris Muir, a Postdoctoral Fellow in the Biodiversity Research Centre at the University of British Columbia.  The title of his talk is:

More than salad: the inner lives of leaves

To most of us, leaves are the green things in a salad or the emblem on our flag. To a biologist, leaves are the critical interface between a plant and its environment. I will talk about some of the remarkable ways that leaves adapt plants to their environment. First, I will cover some basic functions that leaves perform for a plant: How do plants eat? How do plants avoid being eaten? What goes on inside a leaf? Next, I will talk about some of the unorthodox ways that leaves help plants make a living: How do plants without roots get water? Why do leaves track the sun? How did the Swiss Cheese Plant get its holes? The close connection between a leaf’s form and its function to the plant attests to the relentless action of natural selection in adapting organisms to their environment.

Muir has an eponymous website where you can find out more about his work and about him.

Canada’s federal scientists bargain for the right to present scientific results without government interference

I believe this latest bargaining round (h/t Dec. 3, 2014 news item on phys.org) between the Canadian federal government (Treasury Board) and the Professional Institute of the Public Service of Canada (PIPSC; a multi-disciplinary professional union representing 60,000 members employed by the Canadian federal government) is extraordinary. To my knowledge, no other union in this country has ever bargained for the right to present information without political interference or, more briefly, integrity. (Should you know otherwise, please let me know.)

Kathryn May in a Dec. 2, 2014 article for the Ottawa Citizen seems to have broken the news,

The Professional Institute of the Public Service of Canada, which represents more than 15,000 scientists, researchers and engineers, is tabling a negotiating position for managing science in the “public interest” with a list of demands for Treasury Board negotiators that dramatically push the boundaries of traditional collective bargaining in the public service.

The 7,000 members of PIPSC’s large applied science and patent examination group are the first at the table with Treasury Board this week, followed by 2,300 members of the research group next week.

A document obtained by the Citizen shows the union is looking for changes to deal with the ongoing spending cuts in science and “interference” in the integrity of scientific work.

The integrity policies will ensure science is done in the public interest; information and data is shared; scientists can collaborate, seek peer review and be protected from political meddling, “intimidation,” “coercion” or pressure to alter data.

It’s hard to tell how much of this is political grandstanding but it should be noted that there has been international notice of the situation in Canada (from the news article),

About a month ago [late October or early November 2014], hundreds of scientists from around the world signed an open letter appealing to Prime Minister Stephen Harper to end the “burdensome restrictions” Canada’s scientists face in talking about their work and collaborating with international colleagues.

The letter, signed by 800 scientists from 32 countries, was drafted by the Union of Concerned Scientists, which represents U.S. scientists.

May’s article goes on to note,

The union has extensively surveyed federal scientists in recent years and issued two major reports that found scientists don’t feel they can freely speak and that spending cuts are affecting Canadians’ health, safety and environment.

A quarter of scientists surveyed said they have been asked to exclude or alter information. That request, whether explicit or implicit, came from the department, ministers’ offices or the Prime Minister’s Office. At the same time, nearly three-quarters of scientists believe policy is being compromised by political interference.

Specifically, PIPSC wants a scientific integrity policy for Treasury Board and the 40 science-based departments and agencies. The union would be consulted in the drafting and the final policy would be part of the collective agreements and made public.

The policy would touch on a range of issues and existing policies, but the key proposal is the “right to speak.” The union wants a clause guaranteeing scientists the right to express their personal views while making clear they don’t speak for government.

The other big demand is professional development, allowing scientists to attend meetings, conferences and courses to maintain their professional standards.

Do please read May’s article in its entirety (assuming the news paper continues to make it freely available) as it is riveting for anyone interested in this topic.

A Dec. 3, 2014 PIPSC news release provides more details about specific negotiating points,

The proposal being tabled would see enforceable policies negotiated that, among other things, ensure:

  • federal scientists have the right to speak;
  • reinvestment in research programs;
  • adequate national and international collaboration among scientists;
  • preservation of government science knowledge and libraries, and;
  • a guaranteed role in informing evidence-based public policy.

“It’s sad, frankly, that it’s come to this,” added Daviau [Debi Daviau, PIPSC president]. “But negotiating provisions in our collective agreements seems to be the only way to get this government’s attention and adopt meaningful, enforceable scientific integrity standards. At least this way our members would have the chance to grieve violations of standards they argue are essential to maintaining adequate public science services.”

The negotiating point (4th bullet) about libraries seems to have arisen from a specific cost-cutting exercise involving the Dept. of Fisheries and Oceans libraries mentioned in my Jan. 30,  2014 posting. (The disbursement of some priceless volumes along with standard texts appeared to have been done with all the grace and thoughtfulness one would expect from a mindless mob.)

On a related note, I attended a four-day international congress in August 2014 and was surprised by the lack of Canadian scientists at this meeting. Perhaps this is not an area (alternatives to animal testing) where we have invested much research money but it was surprising and somehow shocking that so few Canadian scientists were giving presentations; there was one scientific presentation from a group at the University of British Columbia.

The issues around scientific integrity are complex and I’m not comfortable with the notion of including the principles in a union contract. My experience is that unions can be just as repressive and reductive as any government agency. That said, I think the practice of scientific integrity in Canada needs to be addressed in some fashion and if the only means we have is a union contract then, so be it.

It may be a few weeks before I get back to the topic of scientific integrity and the right to speak as I’m still catching up from all that teaching but I hope to have a more thoughtful and complex piece on these issues written before the year’s end.

ETA Dec. 4, 2014 1245 hours (PDT), coincidentally or not the Canadian federal government announced today * a $1.5 billlion fund (over 10 years) for research (from a Dec. 4, 2014 University of British Columbia [UBC) news release),

The University of British Columbia [UBC] welcomes today’s announcement of the $1.5-billion Canada First Research Excellence Fund (CFREF), designed to significantly enhance the capabilities and competitiveness of Canada’s post-secondary institutions, says President Arvind Gupta.

“Thanks to this investment by the Government of Canada, our universities have an extraordinary opportunity to foster globally significant research on issues that have the capacity to change people’s lives and shape our future,” said Gupta. “Excellence in research makes our reputation, and enables us to attract the best faculty, students and staff from around the world.”

UBC will be among Canada’s top universities competing for up to tens of millions of dollars annually in CFREF funding over the course of the 10-year program. These new funds could support UBC’s emerging research and innovation strategy, designed to put students at the cutting edge of knowledge, providing access to the latest discoveries and revelations, noted Gupta.

UBC is internationally recognized for research excellence in such areas as: Quantum materials; translational genomics and precision oncology; economics; neurosciences; biodiversity; bio-economics; and microbial diversity, among others.

You can read the full UBC news release here. There were a few details more to be had in a U15 Group of Canadian Research Universities Dec. 4, 2014 news release,

The U15 Group of Canadian Research Universities applauds the official launch of the Canada First Research Excellence Fund (CFREF). Prime Minister Stephen Harper launched the Fund today, accompanied by Ed Holder, minister of state for science and technology, at an event attended by representatives from the post-secondary education sector and industry.

“Since its announcement in Budget 2014, The U15 has been looking forward to the official launch of CFREF as a significant commitment by Canada to support globally competitive research excellence,” said Dr. Feridun Hamdullahpur, chair of The U15 and president and vice-chancellor of the University of Waterloo. “This Fund will allow successful institutions to better compete on the international stage in established areas of research strength as well as new and emerging areas that will support Canada’s scientific standing and long-term economic advantage.”

Planets beyond the solar system at Vancouver’s (Canada) Nov. 25, 2014* Café Scientifique

Vancouver’s next Café Scientifique is being held in the back room of the The Railway Club (2nd floor of 579 Dunsmuir St. [at Seymour St.], Vancouver, Canada), on Nov. 25,  2014. Here’s the meeting description (from the Nov. 17, 2014 announcement),

… Our speaker for the evening will be Dr. Aaron Boley. The title of his talk is:

More Than Science Fiction: Planets beyond the Solar System

For centuries we have relied on only the Solar System for understanding our origins. To dream of distant worlds was a mixture of reasoning, conjecture, and science fiction. Now, thousands of planets have been discovered outside of the Solar System, and we continue to learn more about the Solar System itself. In this talk, we will explore the wide variety of planetary systems that have so far been observed in the Galaxy. These new worlds, both alien and familiar, challenge our theories, but also give us new information for unlocking planet formation’s secrets.
