Graphene-based Piezoelectric Supercapacitors for Self-Powered Medical Implants Pilot Project Agreement

2021-09-13 11:49 ET - News Release

Mr. Craig Nicol reports

GMG SUPPORTS QUEENSLAND UNIVERSITY OF TECHNOLOGY DEVELOPMENT OF PIEZO-SUPERCAPACITORS FOR SELF-POWERED MEDICAL IMPLANTS

Graphene Manufacturing Group Ltd. has formalized its support to Queensland University of Technology's Centre for Biomedical Technologies (CBT) for the development of piezo-supercapacitors for self-powered medical implants by a pilot project agreement. The agreement details Graphene Manufacturing Group's contribution of expertise and graphene for the project.

The initial industry engagement grant, entitled "Piezoelectric Supercapacitors for Self-Powered Medical Implants," was awarded to Prof. Cameron Brown, associate professor Deepak Dubal, Dr. Hong Duc Pham and the chief scientific officer of Graphene Manufacturing Group, Dr. Ashok Kumar Nanjundan.

Most modern electrical medical implants (such as pacemakers, insulin delivery pumps) actively regulate or replace bodily functions and thus require batteries capable of reliably functioning for many years without failure. Implanted batteries typically require secondary surgeries for replacement, incurring significant inconvenience to patients in the forms of high costs, discomfort and the risk of infection.

This project aims to develop capability for self-charging medical implants by engineering a novel power unit called a piezo-supercapacitor, which can harvest human body motions, converting that energy into electricity and store it, in a single unit. The concept is based on a mechanism that hybridizes the two processes into one, where the mechanical energy is directly converted and simultaneously stored as electrochemical energy without going through the intermediate step of converting into electricity.

About Graphene Manufacturing Group Ltd.

Graphene Manufacturing Group is a clean tech, disruptive company that produces graphene and hydrogen by cracking methane (natural gas) instead of mining graphite.

Saint Jean Carbon Inc. Update on Guelph Lab & Graphene-based DNA Sensor +++

2021-08-19 09:24 ET - News Release

Dr. William Pfaffenberger reports

SAINT JEAN CARBON PROVIDES PROGRESS UPDATES ON THE SOLID ULTRABATTERY PLANT, MINERAL PROCESSING, CARBON SCIENCES RESEARCH AND OTCQB LISTING

Saint Jean Carbon Inc. has provided updates from its current initiatives.

Solid Ultrabattery

The company's overseas vendor has completed the prototype battery assembly line equipment and subsequent CSA certification. The equipment is currently in transit to the Guelph location and is scheduled to arrive by mid-September. The construction of the battery laboratory at the Guelph plant continues to progress rapidly with the concrete floors and fire-resistant walls now completed in anticipation of the arrival of the prototype battery assembly line. An application for a permit has been submitted to the City of Guelph for approval.

Mining processing

Saint Jean has continued to successfully optimize the computer modelling of its proprietary air classification system which separates graphite ore by means of aerodynamics. The new simulations predict that high-purity graphite can be separated in the first pass through the air classifier, which reduces the number of successive passes required for achieving purification. To validate this product, Saint Jean is currently building a working prototype of this new air classifier design for further prove out. The test feedstock will be supplied from a high-grade ore sample recently extracted from the Montpellier region of Quebec. Preparations are now under way to condition the ore as sample feedstock to the air classifier.

Carbon sciences

Saint Jean, in conjunction with the University of Western Ontario, has successfully demonstrated, in a laboratory environment, a graphene-based DNA sensor, through integrating single-strand DNA conjugated graphene quantum dots. Efforts are now under way to build and demonstrate a graphene-based DNA sensor that will be tested at Saint Jean facilities.

V-Bond Lee, chief commercialization officer of Saint Jean, states: "I am very pleased with the way things are progressing with all our projects. We are building a core team of technical experts that are highly focused on achieving results. I remain very excited about our future technology road map and am confident that we can challenge industry norms in energy storage, critical battery mineral processing and carbon-based sensing products".

OTCQB listing

The company is in the advanced stages of completing an application for its shares to be listed on the OTCQB Market in New York. Once the process completes, the company's symbol on that market will be TORVF. The company's primary listing will remain on the TSX Venture Exchange; however, the OTCQB Market's cross-trading facility will allow Saint Jean to broaden its horizons and provide investors in the United States with the ability to access the company's ordinary shares in U.S. dollars and during U.S. market hours.

Mason to Acquire Graphene Tech from Thomas Swan through Black Swan Graphene Inc.

2021-07-26 10:55 ET - News Release

Mr. Fahad al-Tamimi reports

MASON GRAPHITE ANNOUNCES INVESTMENT IN NEW GRAPHENE VENTURE

Mason Graphite Inc. has launched Black Swan Graphene Inc. and executed, on July 21, 2021, of a definitive agreement pursuant to which Mason Graphite has agreed, through Black Swan Graphene, to purchase strategic assets related to a patented graphene processing technology from Thomas Swan & Co. Ltd., a leading United Kingdom based specialty chemical company founded in 1926 exporting today to over 80 countries.

On closing of the joint venture transaction, Mason Graphite and Thomas Swan will own respectively 66.67 per cent and 33.33 per cent of Black Swan Graphene, which is expected to proceed to a going-public transaction in the coming months.

Since 2012, Thomas Swan has been developing a graphene processing technology, which has now been upscaled three times, from lab scale, through pilot scale to commercial scale. The process allows for the production of high performance graphene at a cost sufficiently low to engender rapid commercial penetration in industrial applications requiring large volumes of graphene and, in turn, requiring large volumes of graphite. The graphene produced by Thomas Swan has reached significant commercial achievements, having undergone thorough customer testing and qualification processes by globally recognized companies in different manufacturing sectors and electronics, notably for mobile handsets, and is expected to be widely used in off-the-shelf products in a near future.

The potential for battery applications was also recently evidenced with the announcement of a collaboration agreement with Johnson Matthey PLC, to use the graphene developed by Thomas Swan to enhance the overall performance of traditional lithium-ion and next-generation batteries (see a joint press release issued on June 22, 2021). Johnson Matthey, an FTSE 100 company listed on the London Stock Exchange, is a global leader in sustainable technologies and innovative battery materials that are expected to significantly improve range and cost of electric vehicles.

In addition to the assets related to the graphene processing technology and associated know-how to be sold to Black Swan Graphene, Thomas Swan will also contribute its exclusive production and commercialization expertise while providing access to subject matter expertise, such as access to personnel and technical support, and deliverables from its operation in northern England. Black Swan Graphene aims to establish a large-scale commercial production facility in Quebec, Canada, in order to leverage the province's competitive and green hydroelectricity as well as the proximity of Mason Graphite's planned production sites. These factors are key and will accelerate the production and commercialization of the graphene developed by Thomas Swan by integrating the supply chain and lowering production costs.

Graphene was first isolated in 2004 in Manchester, United Kingdom, leading to the award of the Nobel Prize in Physics to the two physicists behind the achievement. Similar to the emergence of carbon-fibre technologies of the 1990s, the ability to produce large quantities of graphene at low cost is critical to large-scale commercialization.

Graphene can notably be used to strengthen polymers with obvious applications in the lightweighting of the transportation industry. The polymer additive market is approximately $46-billion (U.S.) annually. Graphene also renders plastics recyclable and is expected to play a significant role in the global effort from governments worldwide to ban single-use plastics. Graphene is also a replacement of carbon black, which has an annual market of more than $17-billion (U.S.). Moreover, graphene is expected to support a breakthrough in lithium-ion battery technology as it allows for a meaningful increase in the silicon content of the battery anode, hence improving battery performance.

Furthermore, graphene can be used in concrete, resulting in a stronger, significantly less permeable and longer-lasting concrete able to achieve equivalent strength while using less volume of materials. As concrete is responsible for approximately 8 per cent of global greenhouse gas emissions, the reduction of concrete usage is paramount in the fight against climate change. Black Swan Graphene will benefit from an established and exclusive commercial relationship between Thomas Swan and Concrene Ltd., a United Kingdom based private nanotechnology company, which has developed a breakthrough graphene-based solution for the concrete industry.

Harry Swan, chief executive officer and owner of Thomas Swan, commented: "After a thorough review of the carbon industry and a long discussion process with several market participants, we are very excited to start this new venture with Mason Graphite, which is advancing a unique graphite project, developing a broad range of carbon-related products and working with several high-profile technical partners. This partnership creates a more efficient supply chain, which will solidify and accelerate the deployment of our graphene processing technology within a burgeoning industry."

Fahad al-Tamimi, chairman of Mason Graphite, commented: "We couldn't be more excited to embark on this new venture with Thomas Swan, a highly respected and dynamic company, in the promising world of graphene. Graphene is no longer theoretical, but undergoing a transformative progress in applications, production and commercialization. Yet, very few companies are able to produce high performance graphene at a cost sufficiently low to penetrate industrial markets; I believe Black Swan Graphene will be one of them. Not only this new venture is expected to create meaningful graphite demand and is therefore a natural extension of the Lac Gueret graphite project, but it truly transforms the company's potential as it elevates Mason to a pre-eminent position within the fastest-growing segment of the carbon industry."

Corporate leadership

The board of Black Swan Graphene will comprise two nominees from Thomas Swan and four nominees from Mason Graphite.

Thomas Swan's nominees are expected to be Harry Swan, chief executive officer and owner of Thomas Swan, and Michael Edwards, business director, advanced materials, of Thomas Swan. Mason Graphite's nominees are expected to be Peter Damouni, executive director of Mason Graphite; Dr. David Deak, an expert in materials science with significant experience in battery materials, including having led special supply chain projects and battery engineering programs for Gigafactory 1 at Tesla Inc. (see full biography herein); Roy McDowall, a director of Mason Graphite; and Simon Marcotte. While Mr. Marcotte will remain as a consultant to Mason Graphite and continue to support specific initiatives undertaken by the company in recent months, for the sake of impartiality, he will step down from the board of Mason Graphite, effective immediately, and will join the board of Black Swan Graphene on the closing of the transaction. Francois Perron will join the board of Mason Graphite, effective immediately (see biography herein).

Mr. al-Tamimi added: "I also take this opportunity to welcome Francois to the board of Mason Graphite. His experience and insight in the mining industry, especially in Quebec, are sure to be highly valuable to the company."

Details of the transaction

Plasma gun sprays out high-quality grapheneThe fast, low-cost method splits graphite particles into graphene flakes, showing promise for mass productionby Prachi Patel, special to C&EN
FEBRUARY 12, 2021

Graphene has slowly made its way into sports gear, anticorrosion coatings, and even fabric face masks. But widespread use of the strong, conductive material in electronics, energy storage, and medical devices hinges on making high-quality graphene affordably and at large scale. Researchers now report an ultrafast way to peel graphene flakes a few atoms thick from graphite using a high-temperature plasma spray process (ACS Nano 2021, DOI: 10.1021/acsnano.0c09451).

The winners of the 2010 Nobel Prize in Physics first lifted monolayers of carbon atoms from graphite, the stuff of pencil lead, using ordinary sticky tape. That slow, painstaking method gives the highest quality graphene. Other exfoliation techniques yield very small amounts of graphene, and the material can have defects. Chemical vapor deposition (CVD), which grows materials from the bottom up, is now the leading method to make large amounts of graphene. But it requires multiple steps and remains expensive. con't....

-----------------------
A team of University of Arkansas physicists has successfully developed a circuit capable of capturing graphene's thermal motion and converting it into an electrical current.

"An energy-harvesting circuit based on graphene could be incorporated into a chip to provide clean, limitless, low-voltage power for small devices or sensors," said Paul Thibado, professor of physics and lead researcher in the discovery.

The findings, published in the journal Physical Review E, are proof of a theory the physicists developed at the U of A three years ago that freestanding graphene—a single layer of carbon atoms—ripples and buckles in a way that holds promise for energy harvesting.

The idea of harvesting energy from graphene is controversial because it refutes physicist Richard Feynman's well-known assertion that the thermal motion of atoms, known as Brownian motion, cannot do work. Thibado's team found that at room temperature the thermal motion of graphene does in fact induce an alternating current (AC) in a circuit, an achievement thought to be impossible.

In the 1950s, physicist Léon Brillouin published a landmark paper refuting the idea that adding a single diode, a one-way electrical gate, to a circuit is the solution to harvesting energy from Brownian motion. Knowing this, Thibado's group built their circuit with two diodes for converting AC into a direct current (DC). With the diodes in opposition allowing the current to flow both ways, they provide separate paths through the circuit, producing a pulsing DC current that performs work on a load resistor.

Additionally, they discovered that their design increased the amount of power delivered. "We also found that the on-off, switch-like behavior of the diodes actually amplifies the power delivered, rather than reducing it, as previously thought," said Thibado. "The rate of change in resistance provided by the diodes adds an extra factor to the power."

The team used a relatively new field of physics to prove the diodes increased the circuit's power. "In proving this power enhancement, we drew from the emergent field of stochastic thermodynamics and extended the nearly century-old, celebrated theory of Nyquist," said coauthor Pradeep Kumar, associate professor of physics and coauthor.

According to Kumar, the graphene and circuit share a symbiotic relationship. Though the thermal environment is performing work on the load resistor, the graphene and circuit are at the same temperature and heat does not flow between the two.

That's an important distinction, said Thibado, because a temperature difference between the graphene and circuit, in a circuit producing power, would contradict the second law of thermodynamics. "This means that the second law of thermodynamics is not violated, nor is there any need to argue that 'Maxwell's Demon' is separating hot and cold electrons," Thibado said.

The team also discovered that the relatively slow motion of graphene induces current in the circuit at low frequencies, which is important from a technological perspective because electronics function more efficiently at lower frequencies.

"People may think that current flowing in a resistor causes it to heat up, but the Brownian current does not. In fact, if no current was flowing, the resistor would cool down," Thibado explained. "What we did was reroute the current in the circuit and transform it into something useful."

The team's next objective is to determine if the DC current can be stored in a capacitor for later use, a goal that requires miniaturizing the circuit and patterning it on a silicon wafer, or chip. If millions of these tiny circuits could be built on a 1-millimeter by 1-millimeter chip, they could serve as a low- power battery replacement.

Globe says Paradigm's Wolff sticks with Nanoxplore "buy" Call

2020-06-04 08:37 ET - In the News

The Globe and Mail reports in its Thursday, June 4, edition that Nanoxplore's third quarter results matched the expectations of Paradigm Capital analyst J. Marvin Wolff. The Globe's David Leeder writes in the Eye On Equities column that accordingly, Mr. Wolff raised his share target to $4.85 CAD from $3.85 CAD. Mr. Wolff is sticking with his "buy" call. Analysts on average target the shares at $3.07. Mr. Wolff says in a note: "With the graphene plant set to start commercial production soon and supply contracts under negotiation, we are maintaining our target EV/EBITDA multiple of 17.5 times using 2023 (a full year of 10,000-tpa graphene production), EBITDA of $48.5-million and a 7.5-per-cent discount rate (10 per cent prior), reflecting management's strong execution ability and the retirement of production risk. We are increasing the target price as the company nears commercial production. While the former Sigma operations will have short-term negative performance, we concentrate on the longer-term highly valued graphene production and value of the graphene production patents."

Top 7 Topics for Materials Science Research in 2020

1. Graphene

Let’s start with graphene, the research topic on our list with by far the highest number of publications in 2018 at over 20,000. Graphene is the material that received the most hype, especially since 2009. It may seem lately from the drop in media reports about the larger than life properties of the thinnest material in the world that graphene was an interesting material for research but has lost it’s novelty factor.

However, the stats above show that the number of publications for graphene is still increasing strongly from year to year, albeit it with a slightly slower rate of increase in comparison to the period from 2009 to 2014.

Why is this? As our understanding of the material matures, research is transitioning into finding ways to produce graphene at larger scales and also into new interesting applications.

Researchers at The University of Manchester have devised graphene sensors embedded into RFIDs, which have the potential to revolutionise the Internet of Things (IoT).

By layering graphene-oxide (a derivative of graphene) over graphene to create a flexible heterostructure the team have developed humidity sensors for remote sensing with the ability to connect to any wireless network.

Graphene was the world's first two-dimensional material isolated in 2004 at The University of Manchester, it is stronger than steel, lightweight, flexible and more conductive than copper.

Since then a whole family of other 2-D materials have been discovered and continues to grow.

Using graphene and other 2-D materials, scientists can layer these materials, similar to stacking bricks of Lego in a precisely chosen sequence known as van der Waals heterostructures to create high-performance structures tailored to a specific purpose.

As reported in Scientific Reports, the groundbreaking nature of this development is that such sensors can be printed layer-by-layer for scalable and mass production at very low cost. The device also requires no battery source as it harvests power from the receiver.

Sensors with a RFID enabler are at the heart of the IoT. This new development can provide various applications such as battery-free smart wireless monitoring for manufacturing processes that are sensitive to moisture, food safety, healthcare and nuclear waste.

The developed technique has the potential to simplify how the information is gathered through its wireless system, nor is it is limited to a particular wireless network and has the ability to be compatible with networks including WiFi and 5G.

Dr. Zhirun Hu who led the work said, "The excitement does not end with this new application here, but leads to the future possibilities of integrations of this technique with other 2-D materials to open up a new horizon of wireless sensing applications."

Professor Sir Kostya Novoselov, who won the Nobel Prize in Physics and coordinated the project, added, "It is the first example of the printable technology where several 2-D materials come together to create a functional device immediately suitable for industrial applications. The Internet of Things is the fast growing segment of technology, and I'm sure that 2-D materials will play an important role there."

Zenyatta to focus on graphene converted from Albany

2018-01-29 17:15 ET - News Release

Mr. Aubrey Eveleigh reports

ZENYATTA WILL FOCUS FUTURE EFFORTS ON VALUE-ADDED GRAPHENE CONVERTED FROM ALBANY GRAPHITE IN A VERTICALLY INTEGRATED STRUCTURE

Zenyatta Ventures Ltd.'s strategic focus is on the extraordinary nanomaterial called graphene, which is easily converted from the company's highly crystalline Albany graphite deposit. Graphene is emerging as the most promising new material in modern times for enhancing applications in various industries due to its unique combination of mechanical, electrical and thermal properties. Graphene, a single sheet of carbon discovered in 2004 at the University of Manchester, can perform all of these functions.

During 2017, independent labs in Japan, United Kingdom, Israel, United States and Canada have demonstrated that Zenyatta's rare form of graphite easily converts (exfoliates) to graphene using a variety of simple mechanical methods. It has become apparent that the effort from these various collaborative programs has created significant additional value for the company's specific material. It is also important to note that the graphene produced by Zenyatta's partners is a consistent and high-quality nanomaterial, including the most desirable, monolayer to trilayer forms. The company's graphene also has excellent dispersion properties and therefore is highly suitable for enhancing present-day composite materials like rubber and concrete, as confirmed by the University of Sussex and the Ben-Gurion University, respectively. The composite material market represents a very-large-volume end use for graphene and graphene-oxide. A significant business opportunity has now evolved related to this graphene product, which currently sells at prices of thousands of U.S. dollars per kilogram*. The prior business model in the company's PEA (preliminary economic assessment) from 2015 included producing and selling high-purity graphite at $7.50 (U.S.) per kg.

Many corporate and academic R&D (research and development) facilities around the world are currently competing to find the most effective, cost-efficient and scalable process to produce high-quality graphene. These companies still require a consistent source (or precursor) material for conversion to graphene, which is then applied to their various products for enhancement. Zenyatta has a significant competitive advantage with the ownership of a large and high-quality supply of source material, Albany graphite, in Canada. The company is currently assessing the various simple graphene conversion methods being utilized on its high-purity graphite material by its network of collaborative partners. Zenyatta plans to source the appropriate equipment required for a graphene manufacturing (exfoliation) process and also evaluate the associated costs for graphene production in a vertically integrated structure.

Zenyatta will continue to focus on advancing the Albany graphite deposit toward production and will supply consistent, high-quality graphite or graphene to its wholly owned subsidiary ZEN-tech Materials Ltd. in a vertically integrated structure. The formation of ZEN-tech is a strategic move that will provide a downstream vehicle to market, capture value and advance graphene application development separate from the mineral development company.

Zenyatta Ventures is developing the 100-per-cent-owned Albany graphite deposit situated in Northeastern Ontario, Canada. The deposit is a large and unique type of igneous-hosted, fluid-derived mineralization containing highly crystalline graphite in two adjacent breccia pipes. The deposit is situated 30 kilometres north of the Trans-Canada Highway, power line and natural gas pipeline near the communities of Constance Lake First Nation and Hearst. A rail line is located 50 kilometres away with an all-weather road approximately 10 km from the deposit.

ZENYATTA VENTURES AND WESTERN UNIVERSITY INITIATE A PROJECT TO DEVELOP GRAPHENE ENHANCED PLASTIC FOR THE AEROSPACE AND AUTOMOTIVE SECTORS

Zenyatta Ventures Ltd. has commenced a collaborative research project with Dr. Takashi Kuboki at Western University to develop an advanced plastic (polymer composite) using Zenyatta graphene (or graphene-oxide) derived from the Albany high-purity graphite deposit. An enhanced polymer composite material will be attractive to the automotive, aerospace and construction industries that seek lightweight materials with added strength, electrical and thermal properties. Graphene, a single sheet of carbon discovered in 2004 at the University of Manchester, is a new and exciting nanomaterial that can perform all of these functions.

The quickest, simplest and most effective way for commercializing large volumes of graphene is to combine it with existing products in the marketplace that need enhancement, like composite materials. Zenyatta recently announced significant success using its high-quality graphene to improve compressive and tensile strength of concrete in Israel and enhanced rubber composites in the United Kingdom. This new project may expand the company's business opportunities as a graphene nanomaterial supplier for the polymer composite markets also.

Zenyatta recently announced the easily exfoliation of Albany graphite via sonication to produce a consistent one- to four-layer graphene which was then homogenously dispersed into a concrete and rubber composite to improve performance. The dispersion quality of the graphene will be of paramount importance for boosting the performance of a polymer composite as well.

Aubrey Eveleigh, president and chief executive officer of Zenyatta, commented: "We continue to find that the unique properties of our graphite enable easy production of a consistent high-quality and easily dispersible graphene which is opening doors for new and important disruptive technologies, especially composites. Zenyatta recently achieved success demonstrating the use of its graphene in concrete and rubber composites with Dr. Oren Regev at Ben-Gurion University in Israel and Dr. Alan Dalton at University of Sussex in England. Using graphene in composites is considered 'low-hanging fruit' and the company will continue to play an increased and active role on collaborative research in this valuable sector."

Dr. Takashi Kuboki, assistant professor of mechanical and materials engineering at Western, commented: "During this research and testing project, injection moulded plastic will be manufactured using Zenyatta's graphene (or graphene oxide) as an additive. Many industries, including aerospace and automotive, are very important to Ontario and Canada. These sectors strive to adopt new technology components made from plastics or polymer composites to reduce weight and improve fuel efficiency but maintain strength. Also, graphene enhanced electrical properties of composites may protect against electrostatic discharge (i.e. lightning) while increased thermal properties are important for dissipating high temperature (i.e. heat sink in electronics)."

This project is receiving federal funding from the Natural Science and Engineering Research Council of Canada (NSERC) Engage Grant program to allow a team of scientists under the direction of Dr. Kuboki at Western in London, Ont., Canada, to carry out this advanced nanomaterial research. There is a significant opportunity for the Canadian plastic and composite manufacturing industry to benefit from a high-quality graphene material located in Northern Ontario to produce new lighter, stronger, more thermally stable technology products. This can contribute to the global competitiveness of a leading-edge domestic industry to enhance the growth of the Canadian economy.

Mr. Eveleigh also stated: "We are very pleased to receive recognition and support from the Canadian NSERC Engage program which complements our various other collaborative research partnerships. The Albany project has the potential to produce high-purity graphite product that is converted to high-quality graphene. This material could lead to high-tech, value-added business opportunities to emerge in Ontario and Canada. On behalf of Zenyatta, I would like to thank the Canadian government for this important support in developing a novel product."

Tokyo Tech Identifies Key Reasons for the Ease & High-yield Conversion of Zenyatta's Albany Graphite to Graphene

2017-10-19 09:02 ET - News Release

Mr. Aubrey Eveleigh reports

Testing results from the Tokyo Institute of Technology in Japan have identified key reasons for the ease and high-yield conversion of Zenyatta Ventures Ltd.'s Albany graphite to graphene.

Research at Tokyo Technology provides exciting feedback on Zenyatta graphene

One of the greatest challenges for commercializing graphene in various applications, since its discovery at the University of Manchester, is how to produce high-quality material, on a large scale at low cost, in a consistent manner.

Dr. Yoshihiko Arao, assistant professor in the department of chemical engineering at Tokyo Tech, stated: "Zenyatta's high-purity graphite material was tested by our scientific team on mechanical conversion to graphene and discovered it converted much easier and with higher yields of graphene than our reference material. We have tested many types of natural graphite but found Zenyatta's graphite material to have better exfoliation performance and produce better graphene particles than the reference material. We believe that this is an extraordinary, unique material and we would like to carry out further collaborative work with Zenyatta on graphene applications."

Research by Dr. Arao and professor Dr. Masatoshi Kubouchi at Tokyo Tech has shown the following significant test results:

D-spacing measurements of Zenyatta carbon material is relatively larger compared with three other commercially available high-purity graphite samples. D-spacing is unique to all crystals and described as the distance between two (graphene) atomic layers or interlayer spacing. The Albany graphite also exhibited some turbostratic structure or natural irregular stacking.
Importantly, these factors have contributed to the ease of conversion and greater yield of high-quality graphene from Albany graphite. This can be attributed to the unusual geologic mode of formation (igneous hydrothermal process) which accounts for the superior purity, crystallinity and overall quality of the graphite found in this unique deposit.
Graphene exfoliated from Albany graphite showed the highest aspect ratio with an average thickness of 1.43 nanometres or one to four graphene layers. Also, the optical absorbance of the Zenyatta graphene dispersion was two to 10 times better than the other three tested reference samples which demonstrate concentrated graphene dispersion can be obtained.
This further confirms the reason for success on graphene development initiatives, especially in composites, from other collaborators in the United Kingdom, Canada, United States and Israel. Tokyo Tech has established that Zenyatta's graphite converts (exfoliates) easily to graphene, producing mono-layer to tri-layer material, has excellent dispersion properties, and is highly suitable for many graphene and graphene-oxide applications.
Aubrey Eveleigh, president and chief executive officer for Zenyatta, stated: "The obstacle to widespread use of graphene since discovery is the high manufacturing cost. A lower-cost and disruptive approach is to use high-purity natural graphite, like Albany material, as the starting point to get easier and higher yields of graphene in an environmentally friendly manner. We are eager to start another phase of testing at a world-class facility like Tokyo Tech using our high-purity graphite material for various innovative graphene applications."

Zenyatta Ventures continues to develop its large and unique Albany graphite deposit in Ontario, Canada. The company's highly crystalline graphite deposit is situated 30 kilometres north of the Trans-Canada Highway, power line and natural gas pipeline near the communities of Constance Lake First Nation and Hearst. A rail line is located 30 km away with an all-weather road approximately 10 km from the graphite deposit. The world trend is to develop products for technological applications that need extraordinary performance using ultrahigh-purity graphite powder and graphene at an affordable cost.

Zenyatta Ventures Ltd. has begun a collaboration program with Alliance Rubber Company and the University of Sussex, United Kingdom, to develop enhanced rubber products using graphene converted from the company's high-purity Albany graphite.

Alliance, an American company founded in 1923, is based in Hot Springs, Ark., that manufactures 2,200 products and markets them in 55 countries. It is financing research at Sussex under the guidance of Dr. Alan Dalton, professor of experimental physics, to develop enhanced new rubber products using graphene produced from Zenyatta graphite. The program is focused on rubber sensor products that will hold credit and debit cards to prevent hacking of information stored on the chip. The global radio frequency identification (RFID) chip market is growing rapidly from $5.6-billion (U.S.) in 2010 to a projected market value of $21.9-billion (U.S.) in 2020*. This market includes software/services, labels, fobs, tags, readers and all other similar types.

The Alliance program will also focus on a rubber sensor product attached to food produce that changes colour when the produce item reaches a set temperature or after a certain amount of time passes since harvest. This product can also act as a bar code on produce in grocery stores.

Jason Risner, director of business strategy at Alliance, stated: "Alliance has a long history of innovation and it is vital for us to play an active role in leading edge rubber technology that uses a disruptive nanomaterial like graphene. It is also critical that we partner with scientific leaders like Dr. Alan Dalton at Sussex and a company like Zenyatta with a special raw material graphite source located in North America."

Graphene can enhance the mechanical, thermal and electrical properties of a vast range of composite materials. It can be added to rubber to make it lighter, stronger and conductive for improving its performance in a large variety of industries.

Separately from the above Alliance project, Zenyatta will also be working with a team of scientists at Sussex under the direction of Dr. Dalton using graphene produced from Zenyatta graphite on other projects such as:

-Motion sensors: Create a flexible (rubber-graphene) sensor that can detect motions as subtle as those associated with breathing and pulse for health care monitors and sportswear use.
-Emulsions: Where the control of electrical and thermal properties is critical for performance. Examples of such applications include inkjet printing, thin wires, stress sensors, thermal management liquids and fluid conductors.
-Energy storage devices -- The goal is to develop supercapacitor devices based on a self-assembly of nanomaterials to produce electrode structures and a better battery using graphene.
-Automotive industry: to develop more sensitive airbags and vehicle batteries made with stacked graphene for faster charging and more energy.
Aubrey Eveleigh, president and chief executive officer of Zenyatta, commented: "We are very pleased to have a collaborative research program with an end-user like Alliance and the great team of scientists at Sussex on exciting new and innovative products. Technology companies around the world are making significant investments which are accelerating the pace of graphene development. We are delighted to play a part in the advancement of this new innovative material by providing a high-quality and consistent graphite material for conversion to graphene."

Zenyatta Ventures forms ZEN-Tech Materials

2017-07-25 08:43 ET - News Release

Mr. Aubrey Eveleigh reports

ZENYATTA ANNOUNCES THE FORMATION OF A WHOLLY OWNED SUBSIDIARY, ZEN-TECH MATERIALS LTD., TO DEVELOP & COMMERCIALIZE GRAPHENE RELATED OPPORTUNITIES

Zenyatta Ventures Ltd. has formed a wholly owned subsidiary called ZEN-tech Materials Ltd. with a registration in England and Wales. ZEN-tech will focus on the development and commercialization activities of graphene applications and the allocation of any associated intellectual property (IP) and worldwide licensing. The formation of ZEN-tech is a strategic move that will provide a vehicle to capture value and advance graphene application development separate from the mineral development company. Zenyatta will continue to focus on advancing the Albany graphite deposit toward production and will supply highly crystalline, purified graphite to ZEN-tech, academics and end-users.

"It has become apparent in the last 12 months that Zenyatta has created additional value from our global collaboration and development related to various graphene initiatives. It makes strategic sense to create a subsidiary to hold the various opportunities and handle these initiatives with our partners," stated Aubrey Eveleigh, president and chief executive officer of Zenyatta. "ZEN-tech has the advantage of developing proprietary graphene-based technology with a consistent supply of high-quality raw material from Zenyatta's wholly owned Albany graphite deposit. We have demonstrated that Zenyatta's graphite converts (exfoliates) easily via sonication to graphene, including mono-layer to tri-layer, has excellent dispersion properties and is highly suitable for many graphene and graphene-oxide applications."

Graphene has shown to enhance the properties of many existing products since its discovery in 2004. The technology pipeline for ZEN-tech includes graphene applications for concrete composites, rubber composites, sensors, filtration, emulsions and silicon-graphene batteries. The formation of a subsidiary will help facilitate and focus the integration of Zenyatta graphene into the next generation of commercial technologies, providing various industries with advanced materials that have improved performance.

ZEN-tech, a private incorporated company, will have access to the high-purity graphite from Zenyatta Ventures for graphene and graphene-related opportunities. There is a high level of interest, especially in Europe, from sophisticated technology or cleantech entities, particularly related to a need for access to a unique raw material graphite source that converts to high-quality graphene for various applications. The United Kingdom is a centre for graphene research, innovation and financing and consequently this attracts many global graphene industry specialists. By locating in U.K., ZEN-tech will be able to tap into the extensive resources available there and will be on the leading edge of the developments in this new and fast growing materials sector. The subsidiary will operate independently of Zenyatta and will be assembling an expert management team once the structure is in place. Details on company structure and related developments will be announced in the near future.

Harbin researchers 3D print the un-printable with graphene oxide injected ink

View Larger Image

Researchers at the Harbin Institute of Technology and Ministry of Education in China have released a paper demonstrating the use of graphene oxide in a 3D printable ink.

The material developed by the team in China exhibits a tensile strength putting it in the same performance range as high-strength concrete, and a level of electrical conductivity among the highest conductive ceramic nanocomposites.

Finding the flow

At its base, the 3D printable ink in this study is a geopolymer – a material first defined in the 1950s with heat resistant and insulating properties, and an ability to encapsulate waste material in its structure. Examples of geopolymers include high temperature ceramics, and concrete made from recycled materials, such as the géobéton created by Russian construction company Renca.

As a raw material, the geopolymer alone does not have the rheological properties to flow through a nozzle for 3D printing. And so, in order to change its rheology (flowability), researchers investigate the use of graphene oxide as an additive.

Materials in the mix

The base geopolymer is made from a mixture of alkaline-source particles, found in soil or clay, and aluminosilicates particles, which is a mineral consisting of aluminium, silicon, and oxygen. During stirring, graphene oxide (GO) particles are injected into the mixture to create four samples of the material with different GO to geopolymer ratios.

What happens in the molecular structure of the geopolymer is that the GO particles act as a kind of lubricant in between the alkaline-source particles and aluminosilicates. The study assumes that interaction between the particles creates a thick layer of water film between them and, as such, GO/Geopolymer inks with higher GO concentration are more fluid than the others.

Printing the un-printable

3D printing this ink is performed using a modified commercially available UP Plus2 3D printer. After direct writing the ink into a design, the structures are cured in a controlled chamber for 5 days. They are then sintered at 1000? to turn the graphene oxide particles of the mixture into graphene, giving extra strength and conductive properties.

As a conclusion, authors state that

The unique properties of GO as we show in this study will further expand the range of applications where GO can be used. In particular, our strategy makes it possible to explore the employment of GO as rheology property modifier by encapsulation, and enable 3D printing materials that was un-printable previously, and thus offer opportunity to create new 3D printing materials

In the form of carbon nanotubes, graphene is gaining widespread popularity in the 3D printing industry. Award winning 3D printer company Markforged is a leader in the field of carbon fiber 3D printers, and fiber-reinforced materials have become a hot topic for applications in automotive and aerospace components.

Researchers at MIT have also taken a theoretical approach to 3D composition of graphene that, by nature, exists as a single-atom sheet.

3D printing strong and conductive geo-polymer nanocomposite structures modified by graphene oxide discussed in this article is published online in Carbon journal, Volume 117, June 2017. It is co-authored by Jing Zhong, Guo-Xiang Zhou, Pei-Gang He, Zhi-Hua Yang and De-Chang Jia.

Talga reports impressive concrete strength test results using its graphene

May 21, 2017

Australia-based technology minerals company, Talga Resources, recently announced impressive initial concrete prototype strength results from trials undertaken at the commercial concrete/cement laboratory of Betotech Baustofflabor in Germany.

Graphene and graphite enhanced cement and concrete are key priority product targets for Talga. Concrete test prototypes were formulated with Talga graphene and graphite additives combined with a European industry cement and aggregate mixture. Results from the trial showed significant increases, about 26% in flexural strength and 14% in compressive strength, using Talga materials over reference concrete at 28 days cure time.

Further optimization of the formulation is planned along with a larger range of performance tests including abrasion, shrinkage and permeability, among other tests. Electrical conductivity tests are also underway. Talga will continue to progress its product and commercialization strategy in the construction sector using these prototype test results as the catalyst to initiate joint development programs with global suppliers.

In September 2016, Zenyatta Ventures announced that it has signed a collaboration agreement with Larisplast, an Israeli business that specializes in the field of concrete admixtures. Zenyatta and Larisplast have both received grant funding from the Canada-Israel Industrial R&D Foundation under the Ontario-Israel Collaboration Program to further test the effect of adding graphene generated from Zenyatta’s Albany graphite to concrete on a pilot scale.

Floating graphene cooks up clean water
BY KATRINA KRÄMER18 MAY 2017

Graphene aerogel converts sunlight into heat to produce water vapour at room temperature

A sunlight-harvesting graphene film can produce steam without boiling the water. The material, which has been made by Chinese scientists, could convert sea or wastewater into drinking water in places where fuel or access to electricity is limited.

Desalinating seawater to make drinking water usually means boiling it, and then collecting and condensing the steam. Heating water to its boiling point, however, requires a great deal of energy either in the form of fuel or electricity. There are solar stills that desalinate water using only sunlight, but they’re slow and not always efficient enough to provide sufficient drinking water for a person’s daily needs.

Xianbao Wang and colleagues from Hubei University have now made a graphene aerogel film capable of producing water vapour at room temperature using only sunlight. The aerogel floats on the surface, where it heats up only a small section of the water column, ‘while the temperature of the bulk water is far below the boiling point’, as Wang explains.

Source: American Chemical Society

The researchers tested how the addition of different materials affected the heating of water in simulated sunlight, including reduced graphene oxide (rGO), graphene oxide (GO), graphene oxide aerogel membrane (GOAM) and the graphene aerogel (GA) that performed best of all

Under simulated sunlight, the aerogel could heat up 100ml of water to 45°C – 13°C higher than water without the aerogel. The material’s porous structure pumps the generated steam away from the surface, allowing water to evaporate 13 times faster than it would without the aerogel.

While other steam-generating materials are based on expensive raw materials such as gold, the basis for Wang’s aerogel is powdered graphite – a cheap and widely available resource. ‘In the context of solar steam generation, the current work has a major contribution in fabricating an efficient sunlight absorber in a simple method, which is scalable,’ comments Satoshi Ishii, a photonics nanoengineering researcher at the National Institute for Materials Science in Japan.

Generating solar steam with the graphene aerogel could be more efficient than using electricity from a photovoltaic cell. ‘The efficiencies of commercial photovoltaic cells are 10–20%, such that the efficiencies of generating steam using photovoltaic cells cannot exceed 20%,’ explains Ishii. Wang’s floating graphene has an efficiency of 54%, reaching up to 83% under focused sunlight.

However, if the material is to be used in a desalination device, Wang’s team will need to improve the material’s toughness – it is easily broken when picked up. ‘I do not see fundamental difficulties in bringing the current technology into real-life applications, although much more feasibility studies should be done,’ adds Ishii.
