Ben-Gurion University of the Negev (BGU) and University of Western Australia researchers have developed a new process to develop few-layer graphene for use in energy storage and other material applications that is faster, potentially scalable and surmounts some of the current graphene production limitations.
BGU explains that current methods for graphene production require toxic chemicals and lengthy and cumbersome processes that result in low yield that is not scalable for commercial applications.
The new revolutionary one-step, high-yield generation process is detailed in the latest issue of Carbon, published by a collaborative team that includes BGU Prof. Jeffrey Gordon of the Alexandre Yersin Department of Solar Energy and Environmental Physics at the Jacob Blaustein Institutes for Desert Research and Prof. H.T. Chua's group at the University of Western Australia (UWA, Perth).
According to the company, its ultra-bright lamp-ablation method surmounts the shortcomings and has succeeded in synthesising few-layer (4-5) graphene in higher yields. It involves a novel optical system that reconstitutes the immense brightness within the plasma of high-power xenon discharge lamps at a remote reactor, where a transparent tube filled with simple, inexpensive graphite is irradiated.
The process is relatively faster, safer and green, devoid of any toxic substances (just graphite plus concentrated light).
Following this proof of concept, the BGU-UWA team is now planning an experimental program to scale up this initial success toward markedly improving the volume and rate at which few-layer (and eventually single-layer) graphene can be synthesised.
Technical Fibre Products (TFP) will exhibit nonwovens for use in surface finishing, imparting EMI shielding or fire protection, and other transport applications, at the JEC Conference on The Future of Composites in Transportation, taking place in Chicago, US, on 27-28 June.
Advanced Engineering 2018, the UK’s annual gathering of OEMs and engineering supply chain professionals, has opened registration for its 10th anniversary show. The first 50 people signing up will be offered a free Ultra High Capacity Power Bank for mobile phones and laptops, to be picked up at the show.
Prodrive Composites reports that it is the first UK carbon composites business to attain full certification against the newly released IATF 16949:2016 automotive standard.
