Grafoid unveils GPURE graphene membrane for Li-ion batteries

Mar 15, 2017

Grafoid logoGrafoid, the Canadian graphene R&D, investment and technology company, announced the development of its GPURE Graphene Polymer nano-porous membrane intended for next generation Li-Ion battery applications.

The GPURE graphene polymer membrane (GPM) was developed as a chemically inert, freestanding membrane using graphene composites to test ion selectivity using both monovalent and divalent ions. Ion selectivity is a key requirement for a semi permeable membrane in a Li-ion battery structure. By protecting the sensitive electrode materials from unwanted chemical species GPURE GPM diffuses only energy harvesting monovalent ions such as Li+, Na+ etc.

Thomas Swan launches a high-performance graphene intermediate product for coatings

Mar 15, 2017

Thomas Swan logoThomas Swan has announced the launch of a high-performance graphene intermediate product for coatings formulators. The new Elicarb Graphene product is a cost effective, stable, easy to handle dispersion of Elicarb Materials Grade Graphene powder for formulation into epoxy-based coating formulations. The product is available now in liter quantities for testing and evaluation.

Thomas Swan has established a 20 tonne per year capability for the manufacture of Elicarb Graphene and Elinova Boron Nitride products at its UK manufacturing site in Consett, County Durham. Elicarb Graphene Epoxy Dispersion is a high performance intermediate product which is intended for further optimization and incorporation into customers’ existing proprietary coating systems. The graphene dispersion is targeted at improving corrosion resistance, thermal conductivity, chemical barrier and mechanical resistance in industrial coatings.

Directa Plus announces graphene-enhanced eyewear collection by Ray-Ban collection with G+ inside

Mar 14, 2017

Directa Plus, a producer and supplier of graphene-based products for use in consumer and industrial markets, recently announced that its graphene-based materials have been selected by Luxottica Group, a company that designs, manufactures and sells eyewear, to enhance a new range of Ray-Ban glasses.

Ray-Ban updates that during the creation process of this collection, every detail—from design to production techniques—has been studied to make the best use of the characteristics of graphene. The molds, for example, were designed with special care to facilitate equal distribution of the material, a special mixture of resins and graphene, all over the front of the frame.

Graphene-Enhanced Composite Materials Improve Lightning-Strike Performance

Haydale Composite Solutions are pleased to announce the production of graphene-enhanced electrically-conductive carbon fibre-reinforced composite materials with improved resistance to damage from a severe lightning-strike event.

Carbon fibre-reinforced composite materials, as used in many aerospace structures and components, are vulnerable to damage from lightning strikes. However, the addition of functionalised nano materials to the epoxy resin through the use of Haydale’s patented plasma functionalisation process, HDPlas™, has been demonstrated to significantly improve the electrical conductivity of the epoxy resin which allows the laminate to dissipate the energy of the lightning strike throughout the structure thereby reducing the localised heating which causes damage in a lightning-strike event. Importantly, these improvements have been achieved without any major issues with existing manufacturing processes.

The AGILE R100 is designed to provide biophysical data to pharmaceutical and biotherapeutics companies seeking more informed decisions earlier in the drug discovery process. However, the company also plans a significant impact on the healthcare industry with innovative new products that enable cutting-edge life science research, drug discovery applications, and diagnostic and health monitoring platforms.

China's Chowei Power announces graphene-enhanced lead-acid battery

Mar 09, 2017

Update: Our sources in china say that it is highly unlikely that this battery actually has any graphene materials in it...

Chinese battery manufacturer Chaowei Power launched a new version of its Black Gold battery — a lead-acid battery that reportedly uses graphene as an additive. The company states that the battery resistance is reduced by 52% and that performance of the battery in low temperature operations has been greatly improved.

Chaowei makes lithium and lead acid automotive batteries under the Chilwee brand. Its Black Gold high-energy VRLA series was launched in February 29, 2016, when it reportedly first applied graphene technology to a commercial, mass-produced rechargeable lead battery.

Graphene may grant control over terahertz waves

Mar 07, 2017

Researchers from the University of Geneva, working with the Federal Polytechnic School in Zurich (ETHZ) and two Spanish research teams, have come up with a technique based on the use of graphene that allows for terahertz waves to be controlled accurately. This discovery paves the way for a practical use of terahertz waves, in particular for imaging and telecommunications.

Graphene to allow control over terahertz waves image

Terahertz waves allow for the detection of materials that are undetectable at other frequencies, but the use of these waves is limited by the absence of suitable devices and materials allowing to control them. The team developed a technique in which graphene allows for the potentially very quick control of both the intensity and the polarization of terahertz light. "The interaction between terahertz radiation and the electrons in graphene is very strong and we have therefore come to the hypothesis that it should be possible to use graphene to manage terahertz waves," the team explains.
