Hector Barron Escobar and his virtual nanomaterial atomic models for the oil, mining, and energy industries

I think there’s some machine translation at work in the Aug. 27, 2015 news item about Hector Barron Escobar on Azonano,

By using supercomputers the team creates virtual atomic models that interact under different conditions before being taken to the real world, allowing savings in time and money.

With the goal of potentiate the oil, mining and energy industries, as well as counteract the emission of greenhouse gases, the nanotechnologist Hector Barron Escobar, designs more efficient and profitable nanomaterials.

The Mexican who lives in Australia studies the physical and chemical properties of platinum and palladium, metal with excellent catalytic properties that improve processes in petrochemistry, solar cells and fuel cells, which because of their scarcity have a high and unprofitable price, hence the need to analyze their properties and make them long lasting.

Structured materials that the specialist in nanotechnology designs can be implemented in the petrochemical and automotive industries. In the first, they accelerate reactions in the production of hydrocarbons, and in the second, nanomaterials are placed in catalytic converters of vehicles to transform the pollutants emitted by combustion into less harmful waste.

An August 26, 2015 Investigación y Desarrollo press release on Alpha Galileo, which originated the news item, continues Barron Escobar’s profile,

PhD Barron Escobar, who majored in physics at the National University of Mexico (UNAM), says that this are created by using virtual supercomputers to interact with atomic models under different conditions before being taken to the real world.

Barron recounts how he came to Australia with an invitation of his doctoral advisor, Amanda Partner with whom he analyzed the electronic properties of gold in the United States.

He explains that using computer models in the Virtual Nanoscience Laboratory (VNLab) in Australia, he creates nanoparticles that interact in different environmental conditions such as temperature and pressure. He also analyzes their mechanical and electronic properties, which provide specific information about behavior and gives the best working conditions. Together, these data serve to establish appropriate patterns or trends in a particular application.

The work of the research team serves as a guide for experts from the University of New South Wales in Australia, with which they cooperate, to build nanoparticles with specific functions. “This way we perform virtual experiments, saving time, money and offer the type of material conditions and ideal size for a specific catalytic reaction, which by the traditional way would cost a lot of money trying to find what is the right substance” Barron Escobar comments.

Currently he designs nanomaterials for the mining company Orica, because in this industry explosives need to be controlled in order to avoid damaging the minerals or the environment.

Research is also immersed in the creation of fuel cells, with the use of the catalysts designed by Barron is possible to produce more electricity without polluting.

Additionally, they enhance the effectiveness of catalytic converters in petrochemistry, where these materials help accelerate oxidation processes of hydrogen and carbon, which are present in all chemical reactions when fuel and gasoline are created. “We can identify the ideal particles for improving this type of reactions.”

The nanotechnology specialist also seeks to analyze the catalytic properties of bimetallic materials like titanium, ruthenium and gold, as their reaction according to size, shape and its components.

Escobar Barron chose to study nanomaterials because it is interesting to see how matter at the nano level completely changes its properties: at large scale it has a definite color, but keep another at a nanoscale, besides many applications can be obtained with these metals.

For anyone interested in Orica, there’s more here on their website; as for Dr. Hector Barron Escobar, there’s this webpage on  Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) website.

Mexican company “Medical and Surgical Center for Retina” and its painless eye drop treatment

I am confined to the materials which have been translated into English so this story is lighter on detail than I would prefer. A June 26, 2015 news item on Azonano describes a company which provides a new painless treatment for secondary blindness,

The Mexican company “Medical and Surgical Center for Retina” created a way to transport drugs, in order to avoid risks and painful treatments in people with secondary blindness due to chronic degenerative blindness such as diabetic retinopathy and degeneration of the eye. The innovative formula results eliminates the need to administrate the drug by intraocular injection.

It is a nanotechnology product, which works with last generation liposomes particles, concentrated in droplets, which function as a conveyor that wraps proteins or antibody fragments and allow its passage into the eye. Once inside, it releases the drugs.

With the nanotechnology product the costs are reduced by 80 to 90 percent and enables the elderly population to make use of it. “With this technology hospitals that have no resources can apply the needed drugs, without requiring a a specialist or a particular facility for the administration. It is necessary to be prescribed by a physician, but it can be administered at home, which lowers the cost. “

A June 25, 2015 Investigación y Desarrollo news release on Alpha Galileo, which originated the news item, provides more information about the company and what seems to be a series of clinical trials both current and upcoming,

The doctor Juan Carlos Altamirano Vallejo, medical director of the Medical and Surgical Center for Retina, mentions that the conditions that originate in the retina are mostly caused by chronic degenerative diseases such as diabetes (diabetic retinopathy) or macular alteration . Patients with this conditions usually require one injection per month which comes at a very high cost and increases if the procedure is needed for both eyes.

The company, located in Jalisco (central west state of Mexico) won the Mexican National Prize for Technology and Innovation and plans to conclude the Clinical Research regulated by the Federal Commission for Protection Against Health Risks (COFEPRIS) next year. The idea is for the medicine to be distributed in state and private health institutions. So far, the achieved results are the same as the ones obtained with intraocular injection, but without the inherent risks of this procedure, such as infection or retinal detachment.

Current talks are being held with COFEPRIS to conduct a study within several diseases and increase its use for different conditions. In the United States, patients who have followed the treatment have had positive results.

The Medical and Surgical Center for Retina provides medical care and a specialized retina Ophthalmology Clinic provides consultation, which also has an area of ​​Biotechnology and Drug Research of Biomedical Engineering, Diagnosis and Treatment Equipment.

Altamirano Vallejo says that receiving the award opens the doors to reach more people and prevent blindness. “It is the most important prize delivered by the Presidency of the Republic in the area of ​​technology and innovation. For us, to have an entity such as the award foundation to guide us and allows us to learn, know skills, strengths and company administration makes us proud, specially the opportunity for a product like this to reach the market and prevent blindness.

Back in an Oct. 9, 2014 posting, I wrote about a couple of nanotechnology-enabled eye drop projects and some of the challenges with trying to bypass the eye’s natural protections.

Finally, I was not able to locate the company (without the Spanish language name that’s not likely to be easy) but there is more information about Investigación y Desarrollo here.

South American countries and others visit Iran’s Nanotechnology Initiative Council

The Iran Nanotechnology Initiative Council (INIC) news release states eight South American countries visited. By my count there were six South American countries (Argentina, Brazil, Ecuador, Bolivia, Venezuela, and Uruguay,), one North American country (Mexico), and one Caribbean country (Cuba). All eight can be described as Latin American countries.

An easy to understand error (I once forgot Mexico is part of North America and, for heaven sakes, I live in Canada and really should know better) as the designations can be confusing. That cleared up, here’s what the June 15, 2015 INIC news release had to say about the visit,

The ambassadors and charge d’affaires of 8 South American countries of Argentina, Brazil, Ecuador, Bolivia, Cuba, Venezuela, Uruguay and Mexico paid a visit to Iran Nanotechnology Initiative Council (INIC) to become familiar with its activities.

Among the objectives of the visit, which was requested by the abovementioned countries, mention can be made of introduction with INIC and its activities, presentation of nanotechnology achievements and products in the country by the INIC, creation and modification of international cooperation and creation of appropriate environment for exporting nanotechnology-based products to these countries.

In this visit, the programs, achievements and objectives of nanotechnology development in Iran were explained by the authorities of INIC. In addition and due to the needs of the countries whose representatives were present in the visit, a number of experts from the Iranian knowledge-based companies presented their nanotechnology products in the fields of packaging of agricultural products with long durability and water purification.

As usual with something from INIC, I long for more detail, e.g., when did the visit take place?

Abakan makes good on Alberta (Canada) promise (coating for better pipeline transport of oil)

It took three years but it seems that US company Abakan Inc.’s announcement of a joint research development centre at the Northern Alberta Institute of Technology (NAIT), (mentioned here in a May 7, 2012 post [US company, Abakan, wants to get in on the Canadian oils sands market]), has borne fruit. A June 8, 2015 news item on Azonano describes the latest developments,

Abakan Inc., an emerging leader in the advanced coatings and metal formulations markets, today announced that it has begun operations at its joint-development facility in Edmonton, Alberta.

Abakan’s subsidiary, MesoCoat Inc., along with the lead project partner, Northern Alberta Institute of Technology (NAIT) will embark on an 18-month collaborative effort to establish a prototype demonstration facility for developing, testing and commercializing wear-resistant clad pipe and components. Western Economic Diversification Canada is also supporting this initiative through a $1.5 million investment toward NAIT. Improvements in wear resistance are expected to make a significant impact in reducing maintenance and downtime costs while increasing productivity in oil sands and other mining applications.

A June 4, 2015 Abakan news release, which originated the news item, provides more detail about the proposed facility, the difficulties encountered during the setup, and some interesting information about pipes,

Abakan shipped its CermaClad high-speed large-area cladding system for installation at the Northern Alberta Institute of Technology’s (NAIT) campus in Edmonton, Alberta in early 2015. Despite delays associated with the installation of some interrelated equipment and machinery, the CermaClad system and other ancillary equipment are now installed at the Edmonton facility. The Edmonton facility is intended to serve as a pilot-scale wear-resistant clad pipe manufacturing facility for the development and qualification of wear-resistant clad pipes, and as a stepping stone for setting-up a full-scale wear-resistant clad pipe manufacturing facility in Alberta. The new facility will also serve as a platform for Abakan’s introduction to the Alberta oil sands market, which, with proven reserves estimated at more than 169 billion barrels, is one of the largest oil resources in the world and a major source of oil for Canada, the United States and Asia. Since Alberta oil sands production is expected to increase significantly over the next decade, producers want to extend the life of the carbon steel pipes used for the hydro-transportation of tailings with harder, tougher coatings that protect pipes from the abrasiveness of tar-like bituminous oil sands.

“Our aim is to fast-track market entry of our wear-resistant clad pipe products for the transportation of oil sands and mining slurries. We have received commitments from oil sands producers in Canada and mining companies in Mexico and Brazil to field-test CermaClad wear-resistant clad pipe products as soon as our system is ready for testing. Apart from our work with conventional less expensive chrome carbide and the more expensive tungsten carbide wear-resistant cladding on pipes, Abakan also expects to introduce new iron-based structurally amorphous metal (SAM) alloy cladding that in testing has exhibited better performance than tungsten carbide cladding, but at a fraction of the cost.” Robert Miller stated further that “although more expensive than the more widely used chrome carbide cladding, our new alloy cladding is expected to be a significantly better value proposition when you consider an estimated life of three times that of chrome carbide cladding and those cost efficiencies that correspond to less downtime revenue losses, and lower maintenance and replacement costs.”

The costs associated with downtime and maintenance in the Alberta oil sands industry estimated at more than $10 billion a year are expected to grow as production expands, according to the Materials and Reliability in Oil Sands (MARIOS) consortium in Alberta. The development of Alberta’s oil sands has been held up by the lack of materials for transport lines and components that are resistant to the highly abrasive slurry. Due to high abrasion, the pipelines have to be rotated every three to four months and replaced every 12 to 15 months. [emphasis mine] The costs involved just in rotating and replacing the pipes is approximately $2 billion annually. The same is true of large components, for example the steel teeth on the giant electric shovels used to recover oil sands, must be replaced approximately every two days.

Abakan’s combination of high productivity coating processes and groundbreaking materials are expected to facilitate significant efficiencies associated with the extraction of these oil resources. Our proprietary materials combined with CermaClad large-area based fusion cladding technology, have demonstrated in laboratory tests a three to eight times improvement in wear and corrosion resistance when compared with traditional weld overlays at costs comparable to rubber and metal matrix composite alternatives. Abakan intends to complete development and initiate field-testing by end of year 2016 and begin the construction of a full-scale wear-resistant clad pipe manufacturing facility in Alberta in early-2017.

Given that there is extensive talk about expanding oil pipelines from Alberta to British Columbia (where I live), the information about the wear and tear is fascinating and disturbing. Emotions are high with regard to the proposed increase in oil flow to the coast as can be seen in a May 27, 2015 article by Mike Howell for the Vancouver Courier about a city hall report on the matter,

A major oil spill in Vancouver waters could potentially expose up to one million people to unsafe levels of a toxic vapour released from diluted bitumen, city council heard Wednesday in a damning city staff report on Kinder Morgan’s proposal to build a pipeline from Alberta to Burnaby [British Columbia].

In presenting the report, deputy city manager Sadhu Johnston outlined scenarios where exposure to the chemical benzene could lead to adverse health effects for residents and visitors, ranging from dizziness to nausea to possible death.

“For folks that are on the seawall, they could be actually struck with this wave of toxic gases that could render them unable to evacuate,” said Johnston, noting 25,000 residents live within 300 metres of the city’s waterfront. “These are serious health impacts. So this is not just about oil hitting shorelines, this is about our residents being exposed to very serious health effects.

  • Kinder Morgan’s own estimate is that pipeline leaks under 75 litres per hour may not be detected.

While I find the presentation’s hysteria a little off-putting, it did alert me to one or two new issues, benzene gas and when spillage from the pipes raises an alarm. For anyone curious about benzene gas and other chemical aspects of an oil spill, there’s a US National Oceanic and Atmospheric Administration (NOAA) webpage titled, Chemistry of an Oil Spill.

Getting back to the pipes, that figure of 75 litres per hour puts a new perspective on the proposed Abakan solution and it suggests that whether or not more and bigger pipes are in our future, we should do a better of job of protecting our environment now. That means better cladding for the pipes and better dispersants and remediation for water, earth, air when there’s a spill.

Graphene not so impermeable after all

I saw the news last week but it took reading Dexter Johnson’s Dec. 2, 2014 post for me to achieve a greater understanding of why graphene’s proton permeability is such a big deal and of the tensions underlying graphene research in the UK.

Let’s start with the news, from a Nov. 26, 2014 news item on Nanowerk (Note: A link has been removed),

Published in the journal Nature (“Proton transport through one-atom-thick crystals”), the discovery could revolutionise fuel cells and other hydrogen-based technologies as they require a barrier that only allow protons – hydrogen atoms stripped off their electrons – to pass through.

In addition, graphene membranes could be used to sieve hydrogen gas out of the atmosphere, where it is present in minute quantities, creating the possibility of electric generators powered by air.

A Nov. 26, 2014 University of Manchester news release, which originated the news item, describes the research in greater detail,

One-atom thick material graphene, first isolated and explored in 2004 by a team at The University of Manchester, is renowned for its barrier properties, which has a number of uses in applications such as corrosion-proof coatings and impermeable packaging.

For example, it would take the lifetime of the universe for hydrogen, the smallest of all atoms, to pierce a graphene monolayer.

Now a group led by Sir Andre Geim tested whether protons are also repelled by graphene. They fully expected that protons would be blocked, as existing theory predicted as little proton permeation as for hydrogen.

Despite the pessimistic prognosis, the researchers found that protons pass through the ultra-thin crystals surprisingly easily, especially at elevated temperatures and if the films were covered with catalytic nanoparticles such as platinum.

The discovery makes monolayers of graphene, and its sister material boron nitride, attractive for possible uses as proton-conducting membranes, which are at the heart of modern fuel cell technology. Fuel cells use oxygen and hydrogen as a fuel and convert the input chemical energy directly into electricity. Without membranes that allow an exclusive flow of protons but prevent other species to pass through, this technology would not exist.

Despite being well-established, fuel-cell technology requires further improvements to make it more widely used. One of the major problems is a fuel crossover through the existing proton membranes, which reduces their efficiency and durability.

The University of Manchester research suggests that the use of graphene or monolayer boron nitride can allow the existing membranes to become thinner and more efficient, with less fuel crossover and poisoning. This can boost competitiveness of fuel cells.

The Manchester group also demonstrated that their one-atom-thick membranes can be used to extract hydrogen from a humid atmosphere. They hypothesise that such harvesting can be combined together with fuel cells to create a mobile electric generator that is fuelled simply by hydrogen present in air.

Marcelo Lozada-Hidalgo, a PhD student and corresponding author of this paper, said: “When you know how it should work, it is a very simple setup. You put a hydrogen-containing gas on one side, apply small electric current and collect pure hydrogen on the other side. This hydrogen can then be burned in a fuel cell.

“We worked with small membranes, and the achieved flow of hydrogen is of course tiny so far. But this is the initial stage of discovery, and the paper is to make experts aware of the existing prospects. To build up and test hydrogen harvesters will require much further effort.”

Dr Sheng Hu, a postdoctoral researcher and the first author in this work, added: “It looks extremely simple and equally promising. Because graphene can be produced these days in square metre sheets, we hope that it will find its way to commercial fuel cells sooner rather than later”.

The work is an international collaboration involving groups from China and the Netherlands who supported theoretical aspects of this research. Marcelo Lozada-Hidalgo is funded by a PhD studentship programme between the National Council of Science and Technology of Mexico and The University of Manchester.

Here’s more about the research and its implications from Dexter Johnson’s Dec. 2, 2014 post on the Nanoclast blog on the IEEE (Institute of Electronics and Electrical Engineers) website (Note: Links have been removed),

This latest development alters the understanding of one of the key properties of graphene: that it is impermeable to all gases and liquids. Even an atom as small as hydrogen would need billions of years for it to pass through the dense electronic cloud of graphene.  In fact, it is this impermeability that has made it attractive for use in gas separation membranes.

But as Geim and his colleagues discovered, in research that was published in the journal Nature, monolayers of graphene and boron nitride are highly permeable to thermal protons under ambient conditions. So hydrogen atoms stripped of their electrons could pass right through the one-atom-thick materials.

The surprising discovery that protons could breach these materials means that that they could be used in proton-conducting membranes (also known as proton exchange membranes), which are central to the functioning of fuel cells. Fuel cells operate through chemical reactions involving hydrogen fuel and oxygen, with the result being electrical energy. The membranes used in the fuel cells are impermeable to oxygen and hydrogen but allow for the passage of protons.

Dexter goes into more detail about hydrogen fuel cells and why this discovery is so exciting. He also provides some insight into the UK’s graphene community (Note: A link has been removed),

While some have been frustrated that Geim has focused his attention on fundamental research rather than becoming more active in the commercialization of graphene, he may have just cracked open graphene’s greatest application possibility to date.

I recommend reading Dexter’s post if you want to learn more about fuel cell technology and the impact this discovery may have.

Richard Van Noorden’s Nov. 27, 2014 article for Nature provides another perspective on this work,

Fuel-cell experts say that the work is proof of principle, but are cautious about its immediate application. Factors such as to how grow a sufficiently clean, large graphene sheet, and its cost and lifetime, would have to be taken into account. “It may or may not be a better membrane for a fuel cell,” says Andrew Herring, a chemical engineer at the Colorado School of Mines in Golden.

Van Noorden also writes about another graphene discovery from last week, which won’t be featured here. Where graphene is concerned I have to draw a line or else this entire blog would be focused on that material alone.

Authenticating ancient Mesoamerican artifacts with nanoSEM

A Nov. 12, 2014 news item on Azonano describes an upcoming Nov. 14, 2014 presentation from researchers at the Smithsonian Institute about authenticating artifacts at the 61st annual AVS symposium being held in Maryland (US) from Nov. 9 – 14 , 2014,

Geologist Timothy Rose of the Smithsonian Institution’s Analytical Laboratories is accustomed to putting his lab’s high-tech nanoscale scanning electron microscope (nanoSEM) to work evaluating the mineral composition of rocks and meteorites. Lately, though, the nanoSEM has been enlisted for a different kind of task: determining the authenticity of ancient Mesoamerican artifacts.

In ongoing studies, Rose and his colleague Jane Walsh have now analyzed hundreds of artifacts, including carved stone figurines and masks and ceramic pieces from the ancient Olmec, Maya, Teotihuacan and Mezcala civilizations dating from 1500 B.C. to A.D. 600. “With our modern imaging and analytical tools we can look at objects at very high magnification, which can reveal new details about how, and sometimes when, objects were created,” he said.

A Nov. 12, 2014 AVS news release, which originated the news item, describes the work in more detail,

The nanoSEM used by Rose and his colleagues has the ability to function over a range of pressures. “Being able to work in the low-vacuum mode allows us to put samples into the microscope au naturel without coating them with an electrically conductive material such as carbon, which would be almost impossible to remove from a specimen,” he said.

In one study, Rose and colleagues used the nanoSEM to study stone masks from Teotihuacan, a pre-Columbian site located 30 miles northwest of Mexico City. The masks, about the size of a human face, were too big to be put into the device (and, more importantly, could not be removed from their respective museums or drilled or otherwise altered to obtain samples for analysis). However, silicone molds that were made of the objects to study tool marks with an optical microscope did remove tiny mineral grains from deep within cracks and drill holes. Chemical evaluation of these grains using the nanoSEM’s X-ray spectrographic analysis system showed that some were diatoms—common single-celled algae with cell walls made of silica. Diatomaceous earth is “a very fine powdery siliceous rock comprised entirely of diatoms that would make very nice polish for the stone of these specific masks,” Rose said. “We believe we found abrasive grains and polish that was used in the manufacturing process.”

In a separate study of artifacts confiscated by the federal government, the researchers found some pieces to be partially coated with a layer of what looked to be modern gypsum plaster. In other words, the pieces were fakes. However, Rose noted, a surprisingly small percentage of the objects evaluated to date have shown modern tools marks or other evidence of recent origins. One unique ceramic handled pot analyzed in detail, for example, had five chemically distinct layers that appeared to be original Olmec fresco paint—a level of craftsmanship that, he said, is unlikely to have been the work of modern artisans.

Presentation #CS-FrM3, “Faces from the Past: Microbeam Imaging and Analysis of Artifacts from Ancient Mesoamerica,” is at 9:00 a.m. Eastern Time on Friday, Nov. 14, 2014.

AVS provides a symposium introduction page explaining the purpose of these meetings,

The AVS International Symposium and Exhibition addresses cutting-edge issues associated with materials, processing, and interfaces in both the research and manufacturing communities. The weeklong Symposium fosters a multidisciplinary environment that cuts across traditional boundaries between disciplines, featuring papers from AVS technical divisions, technology groups, and focus topics on emerging technologies. The equipment exhibition is one of the largest in the world and provides an excellent opportunity to view the latest products and services offered by over 200 participating companies. More than 2,000 scientists and engineers gather from around the world to attend.

At one time, AVS stood for American Vacuum Society but over time things change and while I imagine they didn’t want to lose their branding as AVS, they also didn’t want to constrain themselves with the word ‘vacuum’, hence the change to AVS as a ‘word’ much like IBM doesn’t refer to itself by its original name, International Business Machines.

MIT (Massachusetts Institute of Technology) signs agreement with Mexican university, Tecnológico de Monterrey

The deal signed by the Massachusetts Institute of Technology (MIT) and one of the largest universities in Latin America covers a five-year period and its initial focus is on nanoscience and nanotechnology. From a Nov. 3, 2014 news item on Azonano,

MIT has established a formal relationship with Tecnológico de Monterrey, one of Latin America’s largest universities, to bring students and faculty from Mexico to Cambridge [Massachusetts, US] for fellowships, internships, and research stays in MIT labs and centers. The agreement will initially focus on research at the frontier of nanoscience and nanotechnology.

An Oct. 31, 2014 MIT news release, which originated the news item, describes the deal and the longstanding relationship between the two institutions,

The agreement was celebrated today with a signing ceremony at MIT attended by a delegation from Tecnológico de Monterrey that included President Salvador Alva; the chairman of the board of trustees, José Antonio Fernández Carbajal; Mexico’s ambassador to the United States, Eduardo Medina Mora; and Daniel Hernández Joseph, the consul general of Mexico in Boston.

“We feel honored for the confidence that the MIT community has placed in us,” Alva says. “Our goal is to educate even more entrepreneurial leaders with the capacity and the motivation to solve humanity’s grand challenges. Leaders capable of creating and sustaining economic and social value. Leaders that will transform the lives of millions of people.”

The agreement sets the stage for increasing long-term cooperation and collaboration between the two universities with an initial academic program that will enable undergraduates, graduate students, postdocs, and junior faculty from Tecnológico de Monterrey to visit the MIT campus, where they will be embedded in labs and centers alongside MIT faculty and students. The participants will gain direct experience in disciplines and topics that match their interests. The program may change or expand its focus after five years.

“The goal for the first five years is to provide students and scholars from Tecnológico de Monterrey with a world-class research experience in nanoscience and nanotechnology and to accelerate research programs of critical importance to Mexico and the world,” says Jesús del Álamo, the Donner Professor of Electrical Engineering, who will coordinate the program at MIT. “And because faculty hosts of participants in the initial program will be recruited from any MIT academic department with relevant activities, we will be able to accommodate interests in nanoscale research over a very broad intellectual front.”

MIT is currently constructing a new facility, MIT.nano, that will be a key resource for future extensions of the program. The new 200,000-square-foot facility, which is being constructed on the site of Building 12 at the center of the MIT campus, will house state-of-the-art cleanroom, imaging, and prototyping facilities supporting research with nanoscale materials and processes — in fields including energy, health, life sciences, quantum sciences, electronics, and manufacturing.

In honor of the new relationship, the facility’s Computer-Aided Visualization Environment will be named after Tecnológico de Monterrey, says Vladimir Bulović, the Fariborz Maseeh Chair in Emerging Technology and faculty lead for the MIT.nano building project.

“When it is completed, MIT.nano will enable students and faculty from Tecnológico de Monterrey to learn and work in one of the most advanced facilities in the world and will give them invaluable experience at the forefront of innovation,” says Bulović, who is also the associate dean for innovation in MIT’s School of Engineering and co-chair of the MIT Innovation Initiative.

Tecnológico de Monterrey is one of the largest universities in Latin America, with nearly 100,000 high school, undergraduate, and graduate students; 31 campuses in Mexico; and 19 international locations and branches in the Americas, Europe, and Japan. This week’s agreement establishes a new relationship between MIT and Tecnológico de Monterrey, but the two institutions have a shared history.

Tecnológico de Monterrey was founded in 1943 by Eugenio Garza Sada, who graduated from MIT in 1914 with a degree in civil engineering. After studying at MIT, Garza Sada — with his brother, Roberto, who graduated from MIT in 1918 — grew his family’s brewery in Mexico into a company that today is known as FEMSA, the largest beverage company in Mexico and Latin America. Tecnológico de Monterrey’s founding director-general was León Ávalos Vez, a mechanical engineer from the MIT Class of 1929.

“We believe that both MIT and Tecnológico de Monterrey play a leadership role in shaping minds and creating knowledge, in serving as catalysts for innovation, entrepreneurship and economic growth, but they also have a responsibility to address the critical problems in the world,” says Fernández, the chairman of the board of trustees at Tecnológico de Monterrey. “This agreement will encourage the implementation of educational programs and accelerate research in nanotechnology in ways that will truly make a difference.”

The new program will commence next spring, with the first students and faculty targeted to come to MIT next summer [2015].

It’ll be interesting to note if this exchange ever reverses and MIT students start visiting Tecnológico de Monterrey campuses. It seems there’s a quite a selection with 31 in Mexico and 19 in various locations internationally.

Nanofiltration of heavy metals from water in Mexico

A June 3, 2013 news item on Nanowerk highlights a technology for filtering heavy metals from water,

The methods traditionally used to remove heavy metals from wastewater have limitations because they only withdraw a certain percentage and the remaining amount is very difficult to remove. This motivated a young graduate researcher at the National Polytechnic Institute (IPN) in Mexico, Gabriel Ramirez Monter, to create a technology capable of removing such contaminants at low cost and with an efficiency that surpasses existing technologies.

According to Monter Ramirez, this project led him to design some structures called dendrimers, which are highly branched molecules with shape similar to a shrub or a tree with multiple branches.

“Dendrimers adhere and spread on a microfiltration membrane; ie, thin sheets of porous material that are not normally capable of retaining heavy metals due to its pore size. Once placed, it achieves total removal of heavy metal ions in the same way a marine anemone would act, using tentacles to concentrate and catch food; in this case, the branches of the dendrimers capture pollutants, “says the researcher.

He explains that through dendrimers the team converted a microfiltration membrane into a nanofiltration one. “Another advantage of these structures is that they can be washed and reused, plus the captured metals are removed without problem.”

A May 27, 2014 Investigación y Desarrollo news release (Spanish language), which originated the news item, provides more details (or you can check Nanowerk for an English translation).

After some searching I found this 2012 YouTube presentation featuring researcher, Gabriel Ramirez Monter, discussing his work in Spanish,

According to the news item on Nanowerk, Ramirez Monter is in the early stages of commercializing his work. While the partner organization is identified as ‘Nanotecnología México’, I believe the correct name is Nano Tec México.

Canadian nanobusiness news bitlets: NanoStruck and Lomiko Metals

The two items or ‘news bitlets’ about Canadian nano business don’t amount to much; one concerns a letter of intent and the other, an offer of warrants (like stock options) which likely expired today (March 13, 2014).

It seems NanoStruck Technologies is continuing to make headway in Mexico (as per my Feb. 19, 2014 posting about the company’s LOI and gold mine tailings in Zacatecas state) as the company has signed another letter of intent (LOI), this time, to treat wastewater in the region of Cabo Corrientes. From a March 11, 2014 news item on Azonano,

NanoStruck Technologies Inc. (the “Company” or “NanoStruck”) announces the signing of a Letter of Intent (LOI) with the town of El Tuito to use the Company’s NanoPure technology to treat wastewater from the municipality of Cabo Corrientes in Mexico.

The parties are in dialogue for the treatment of household residual water, which contains food, biodegradable matter, kitchen waste and organic materials. The Company’s NanoPure solution uses chemical-free processes and proprietary nano powders that can be customised to remove such contaminants.

The March 10, 2014 NanoStruck Technologies news release (which originated the news item) link on the company website leads to the full text here on heraldonline.com (Note: Links have been removed),

Homero Romero Amaral, President of the Municipality of Cabo Corrientes said: “NanoStruck’s NanoPure technology is a proven solution for the treatment of residual water in an environmentally friendly way. Its low energy consumption means it also maintains a low carbon footprint.”

Bundeep Singh Rangar, Interim CEO and Chairman of the Board said: “We are privileged to be given the opportunity to work with the Cabo Corrientes municipality to create a long-term residual wastewater treatment solution.”

El Tuito is the capital of Cabo Corrientes, a cape on the Pacific coast of the Mexican state of Jalisco. It marks the southernmost point of the Bahía de Banderas (Bay of Flags), where the port and resort city of Puerto Vallarta is situated.

The Municipality and NanoStruck have commenced negotiation of a definitive agreement regarding the use of the NanoPure technology and hope to complete a binding agreement within 90 days.

My next bitlet concerns, Lomiko Metals and its short form prospectus and offering. From the company’s March 7, 2014 news release (also available on MarketWired),

LOMIKO METALS INC. (TSX VENTURE:LMR) (the “Company” or “Lomiko”) is pleased to announce that it has obtained a final receipt for its short form prospectus (the “Prospectus”) in each of the provinces of British Columbia, Alberta and Ontario, which qualifies the distribution (the “Public Offering”) of (i) a minimum of 6,818,182 units (the “Units”) and a maximum of 27,272,727 Units of the Company at a price of $0.11 per Unit, and (ii) a maximum of 7,692,308 flow-through units (the “Flow-Through Units”) of the Company at a price of $0.13 per Flow-Through Unit, for minimum total gross proceeds of $750,000 and maximum total gross proceeds of $4,000,000.

Each Unit consists of one common share of the Company (each, a “Common Share”) and one-half of one common share purchase warrant (each whole warrant being a “Unit Warrant”). Each Flow-Through Unit consists of one Common Share to be issued on a “flow-through” basis within the meaning of the Income Tax Act (Canada) (each a “Flow-Through Share”) and one-half of one common share purchase warrant (each whole warrant being a “Flow-Through Unit Warrant”).

Each Unit Warrant will entitle the holder thereof to purchase one common share of the Company (the “Unit Warrant Shares”) at a price of $0.15 per Unit Warrant Share at at any time before the date that is 18 months following the closing date of the Public Offering. Each Flow-Through Unit Warrant will entitle the holder thereof to purchase one common share of the Company (the “Flow-Through Unit Warrant Shares”) at a price of $0.20 per Flow-Through Unit Warrant Share at at any time before the date that is 18 months following the closing date of the Public Offering. The Public Offering will be conducted on a “best effort” agency basis through Secutor Capital Management Corporation (the “Agent”), pursuant to an agency agreement dated March 6, 2014 (the “Agency Agreement”) between the Company and the Agent in respect of the Public Offering.

Pursuant to the Agency Agreement, the Company has also granted an over-allotment option to the Agent, exercisable for a period of 30 days following the closing of the Public Offering, in whole or in part, to purchase additional Units and Flow-Through Units in a maximum number equal to up to 15% of the number of Units and Flow-Through Units respectively sold pursuant to the Public Offering. In connection with the Public Offering, the Company will pay the Agent a cash commission equal to 8% of the gross proceeds of the Public Offering and grant compensation options to the Agent entitling it to purchase that number of common shares of the Company equal to 6% of the aggregate number of Units and Flow-Through Units issued and sold under the Public Offering (including the over-allotment option) for a period of 18 months following the closing date of the Public Offering, at a price of $0.11 per common share.

The Company is also pleased to announce it has received conditional approval from the TSX Venture Exchange for its previously announced concurrent non-brokered offering of up to 15,346,231 flow-through units (the “Private Placement Units”) for additional gross proceeds of $2,000,000 (the “Private Placement”). The securities underlying the Private Placement Units will be issued on the same terms as the securities underlying the Flow-Through Units to be issued under the Public Offering. The Company has agreed to pay to Secutor Capital Management Corporation a finder’s fee of 8% in cash and the issuance of a warrant to purchase the number of common shares of the Company equal to 6%, exercisable at $0.13 per share for 18 months from the date of issuance. The securities to be issued under the Private Placement will be subject to a four-month hold period from the closing date of the Private Placement.

The net proceeds from the Public Offering and the Private Placement will be used by Lomiko primarily in connection with the exploration program on the Quatre-Milles East and West mineral properties (Quebec), for business development and for working capital and general corporate purposes. In particular, the proceeds of the flow-through shares under the Public Offering and the Private Placement will be used by the Company to incur eligible Canadian Exploration Expenses as defined by the Income Tax Act (Canada).

Closing of the Public Offering and of the Private Placement is expected to occur on or about March 13, 2014, or such other date as the Agent and the Company may determine. The TSX Venture Exchange has conditionally approved the listing of the securities to be issued pursuant to the Public Offering and the Private Placement. The Public Offering and the Private Placement are subject to customary conditions and the final approval of the TSX Venture Exchange.

The Units, the Flow-Through Units and the Private Placement Units have not been, nor will they be, registered under the United States Securities Act of 1933, as amended (the “1933 Act”), and may not be offered, sold or delivered, directly or indirectly, within the United States, or to or for the account or benefit of U.S. persons unless the Units, the Flow-Through Units and the Private Placement Units are registered under the 1933 Act or pursuant to an applicable exemption from the registration requirements of the 1933 Act. This press release does not constitute an offer to sell, nor it is a solicitation of an offer of securities, nor shall there be any sale of securities in any state of the United States in which such offer, solicitation or sale would be unlawful.

You’re on your own with regard to determining how good an investment this company might be. The company’s March 10, 2014 newsletter does point to two analyses (although, again, you’re on your own as to whether or not these are reputable analysts), The first analyst is Gary Anderson (self-described as a Investor, trader, researcher, and writer- exclusively in 3D Printing Stocks.). He writes this in a Dec. 27, 2013 posting on 3DPrintingStocks.com,

I spend a great deal of time looking for what I believe are legitimate, undiscovered stocks in the 3D printing space because I believe that’s where the major gains will be over a 3-6 month period as they undergo discovery by the broader market.

The little-known penny stock [Lomiko Metals] I’m introducing today has legitimate upside potential for 3D printing investors based on four factors:

  1. The market for their product
  2. Current and potential future value of existing assets
  3. Supply and demand imbalance predicted
  4. Entrance into 3D printing materials market with an established leader

….

3D printing investors looking for a materials supplier as part of their 3D printing portfolio may want to consider Lomiko Metals.  I believe there is limited downside risk at current levels due to the intrinsic value of the company’s hard assets in their Quatre Milles graphite property, and potential for significant share price appreciation due to the four factors discussed above.

Graphene has extraordinary potential as a game-changing material for 3D printing.  Early movers like Lomiko Metals in partnership with Graphene Labs could become the beneficiaries of this amazing material’s potential as it becomes commercialized and utilized in 3D printed components and products that contain revolutionary properties.

Disclosure:    I am long shares of Lomiko Metals.  I received no compensation from Lomiko Metals or any third party for this article.

NanoStruck’s Letter of Intent about gold tailings in Mexico

As I’ve come to expect from Canadian company NanoStruck, there’s not much detail in this Feb. 19, 2014 news item on Nanowerk,

NanoStruck Technologies Inc. announces a non-binding Letter of Intent (“LOI”) signed with Tierra Nuevo Mining Ltd (TNM), a private exploration company with mining assets in Mexico BG Partners Corp., brought this business relationship to NanoStruck.

The Feb. 18, 2014 NanoStruck news release, which originated the news item, describes the property where the Tierra Nuevo Mining would like to test NanoStruck’s technology,

The LOI is to explore the potential of TNM engaging NanoStruck to recover gold and silver from TMN’s tailings material using the NanoMet Technology at TNM’s Noche Buena Mine site, located in Zacatecas state, 10 kilometers northeast of Goldcorp’s Peñasquito Mine. The Noche Buena mine began operations sometime between 1926 and 1930 and was worked continuously until 1992 when it was shut down due to the collapse of metal prices.

Brian Mok, Senior Mining Consultant at BG Partners Corp. said: “This is a great opportunity for NanoStruck to demonstrate its technology and expertise in the mine tailings industry.”

Bundeep Singh Rangar, interim CEO and Chairman of the Board said: “A credible counter-party greatly accelerates the development and go-to-market strategy of our unique mine tailings processing technology.”

I last wrote about NanoStruck and mine tailings in a Feb. 10, 2014 posting titled: 96% of 9.1 grams per metric ton, or 0.32 ounces per ton, of gold recovered in gold tailings tests. As I noted at the time, I am hopeful the company will provide more information as to its technology at some point in the future, preferably sooner rather than later.
