A Swinburne project for safe and durable graphene supercapacitors gets closer to commercialization

Jun 19, 2017

Researchers at Swinburne University are progressing towards producing commercially viable, chemical-free, long-lasting, safe energy devices. The team is developing the Bolt Electricity Storage Technology (BEST) – a graphene oxide-based supercapacitor offering high performance and low-cost energy storage.

The team explains that this technology is this and environmentally friendly, and a patent was recently filed on it. It is reportedly on the brink of becoming a commercial prototype. Also stated was that investment in the technology's development will soon be under way through Graphene Solutions, a joint venture between graphite miner First Graphite Resources (FGR) and Australia-based electronics company Kremford.

Zenyatta Ventures and Lakehead University announce scale-up of GO program

Jun 16, 2017

Zenyatta Ventures has announced a program for a scaled-up production method of its graphite to graphene oxide for applications like water treatment, sensors, supercapacitors and Li‐ion batteries. The program is receiving grant funding from the Ontario Centres for Excellence (OCE) to allow a team of scientists at Lakehead University in Ontario, Canada to carry out this research.

The OCE funding helps established Ontario‐based companies develop, implement and commercialize technical innovations by supporting partnerships with publicly‐funded post‐secondary institutions. The focus of the research work will be on scaling up production methods for Zenyatta’s graphite to GO, a first critical step towards commercialization of the technology. The OCE VIP II $100,000 grant will be administered over two years and Zenyatta will be contributing $50,000 in cash and $60,000 in‐kind support to the project.

NanoXplore's CEO discusses the company's business and upcoming public offering

Jun 15, 2017

A few days ago Canada-based Group NanoXplore announced that it is will merge with Graniz Modal to become a public company that trades in the Canadian stock exchange. NanoXPlore's CEO and President, Dr. Soroush Nazarpour, was kind enough to answer a few questions we had regarding this IPO and NanoXplore's business.

Q: Group NanoXplore is set to become a public company soon, following the merger with Graniz Modal. Can you detail the effect this will have on NanoXplore?

Graphene-based transistor to potentially make ultra-fast computers

Jun 14, 2017

Researchers at the University of Central Florida, the University of Texas at Dallas and other collaborators have designed a graphene-based transistor which could be used to create an all-carbon spin logic design with the potential to someday lead to computers that are a thousand times faster and use a hundredth of the power.

UCF's GNR's for  graphene transistor image

The team found that by applying a magnetic field to a graphene ribbon, it is possible to change the resistance of current flowing through it. For this device, the magnetic field is controlled by increasing or decreasing the current through adjacent carbon nanotubes. Increasing or decreasing the strength of the magnetic field would also increase or decrease the flow of current through this new kind of transistor, much like a valve controlling the flow of water through a pipe.

Graphene 3D Lab releases Graphene-HIPS 3D printing filament

Jun 13, 2017

Graphene 3D Lab has announced the launch of a new graphene-enhanced 3D printing filament - the Graphene-HIPS. It is said to be a distinctly engineered and innovative semi-flexible FDM 3D Printing material reinforced with graphene and designed for high performance 3D printing.

This FDM material reportedly exhibits excellent interlayer adhesion, toughness and superb impact resistance. These properties provide an excellent mechanical and structural performance for 3D printed objects made from this material. It is well suited for printing precise functional components for engineering applications. Graphene-HIPS is both temperature and weather resistant, which makes it an ideal material for outdoor projects.

Fisker's first gen of EVs to use Li-ion batteries, graphene-based ones still under development

Jun 13, 2017

Henrik Fisker, initiator of a project to start an electric car company relying on a long-range battery that uses graphene, recently stated that the company's upcoming electric luxury sedan will use lithium-ion batteries to power the car rather than the graphene battery technology currently under development for future models.

EMotion is slated to officially debut on August 17, 2017 with a tentative release in 2019. Pricing starts at $129,900, placing it in the same range as Tesla Model S. It will be interesting to see at what point, if at all, graphene-based batteries will be used in these cars.

Researchers create color-changing nanomaterials using graphene oxide

Jun 12, 2017

Researchers affiliated with UNIST (Ulsan National Institute of Science and Technology) in Korea have engineered a new type of carbon nanomaterials, reportedly capable of changing shapes and colors depending on the type of solvents used. Such materials have attracted much attention thanks to their unique optical properties and structures.

The research team has presented a unique design and synthesis of hybrid carbon nanosheets (CNSs), which show a strong solvatochromic behavior (the ability of a chemical to change color due to a change in solvent polarity) with wide color tunability ranging from blue to orange and even to white in various solvents. This unique hybrid CNS features clusters of carbon nanorings on the surface of graphene-oxide (GO) nanosheets as the product of the hydrothermal reaction of small molecular precursors in the presence of GO nanosheets. Moreover, under UV and visible-light excitation, the hybrid CNS exhibits tunable emission spanning the wide range of colors in a series of solvents with different polarities.
