Versarien reports strong performance in World Cup competition using graphene-enhanced equipment

Versarien LogoVersarien has noted the recent strong performances by British Skeleton World Cup competitor Dominic Parsons utilizing graphene-enhanced equipment provided by Versarien’s collaboration partner Bromley Technologies.

Versarien has been collaborating with Bromley since May 2016 to incorporate Versarien’s graphene enhanced carbon fibre into the skeleton sleds being produced by Bromley. Utilizing one of three Bromley X22 prototype sleds, Parsons set the fastest speed of 137.3 km/hr at the International Bobsleigh & Skeleton Federation World Cup Race in St. Moritz.

Crumpled graphene balls to enhance Li-ion batteries by preventing dendrite growth

Researchers at Northwestern University in the U.S have designed a way to use "crumpled graphene balls" to improve Li-ion batteries. The team explained that in current batteries, lithium is usually atomically distributed in another material like graphite or silicon in the anode. However, using an additional material 'dilutes' the battery's performance.

Since Lithium is a metal, it sounds logical to use lithium by itself, but researchers have spent years trying to do so without sufficient success. The biggest challenge has been that when lithium charges and discharges, it can generate dendrites and filaments, with implications for safety and reliability. The team said: "At best, it leads to rapid degradation of the battery's performance. At worst, it causes the battery to short or even catch fire."

New graphene-based 'atomristors' could pave the way towards more powerful computing

Researchers at The University of Texas at Austin, in collaboration with Peking University scientists, have developed what they refer to as the thinnest memory storage device with dense memory capacity, paving the way for faster, smaller and smarter computer chips for everything from consumer electronics to big data to brain-inspired computing.

They named their creation "atomristors", and stated that before this work, it was considered impossible to make memory devices from materials that were only one atomic layer thick, The the "atomristors" improve upon memristors, an emerging memory storage technology with lower memory scalability.

New graphene-based catalyst for hydrogen production could be a step toward clean fuel

Researchers at UC Santa Cruz South and the China University of Technology have developed a graphene-based nanostructured composite material that shows impressive performance as a catalyst for the electrochemical splitting of water to produce hydrogen. An efficient, low-cost catalyst is essential for realizing the promise of hydrogen as a clean, environmentally friendly fuel.

The team has been investigating the use of carbon-based nanostructured materials as catalysts for the reaction that generates hydrogen from water. In a recent study, they obtained good results by incorporating ruthenium ions into a sheet-like nanostructure composed of carbon nitride. Performance was further improved by combining the ruthenium-doped carbon nitride with graphene, to form a layered composite.

XG Sciences to expand with new graphene production facility

XG Sciences, a US-based developer and producer of graphene flakes, has announced its plan to invest millions in expanding its Lansing-area facilities. The company will start operating out of new 64,000 square-foot facility in Vevay Township in March.

The company was formed in 2006 based on work out of Michigan State University. The company's technology can be used in automotive batteries and as wire coatings in electronics to prevent microchips from overheating. Some of the material has been used in Samsung phones as a thermally conductive adhesive, said current CEO Philip Rose. Rose also said the expansion marks the first phase in a move toward larger scale commercialization for the company.

Dotz Nano enter MOU with Recochem and eyes the Australia and NZ markets

Dotz Nano is now planning to sell its graphene quantum dots into Australia and New Zealand after entering an exclusive distribution agreement with Australia-based Recochem. The agreement between the companies allows for a five-month evaluation period where the companies can explore each other’s performance in the regions’ markets, with a comprehensive agreement to be finalized by June.

Under the initial MoU, Dotz Nano will provide Recochem with samples of its graphene quantum dots for numerous applications, with sales terms to be agreed on a customer-by-customer basis.

GF1 - a new smart health watch with a CVD graphene touch screen

Wuxi Graphene Film, a wholly-owned subsidiary of The Sixth Elements Materials, has launched a new graphene-enhanced product in the Chinese market: The GF1 Graphene Watch. It is a smart health watch, with CVD graphene film acting as the conductive element for the touch screen (as a replacement for the usually-used ITO).

The Company kindly sent us one of these new watches to try out. So thanks! and here are our impressions: First of all, it is an attractive-looking watch, with a futuristic design and a quality feel to it. The display is a 1.3'' monochrome white OLED with a 128X64 resolution. The watch comes with an accompanying app, and includes features like pulse and heart rate monitoring, step meter, sleep quality tracking and more.

Haydale and Talga sign a commercial supply and development agreement

Haydale logoTalga Resources logo 2017UK-based advanced materials group Haydale Graphene Industries has entered into a commercial supply and development agreement with Australian-listed Talga Resources. The agreement will see the two companies work together on the production, sales and marketing of jointly developed graphene-based transparent conductive ink products for industrial applications in Asia.

The two companies have been working together for a few years, and will now look to enhance the properties of Haydale’s graphene-based, transparent conductive ink by using Talga’s highly conductive graphitic materials. Initial tests showed that Talga’s material can enhance electrical conductivity of Haydale's transparent inks by 15% or more above that of synthetic graphite.
