The team reports that robust detection in a wide range of NO2 concentrations, 10-154 ppb, was achieved, highlighting the great potential for graphene-based NO2 sensors, with applications in environmental pollution monitoring, portable monitors, automotive and mobile sensors for a global real-time monitoring network.

Talga reports positive initial test results on its graphene silicon lithium-ion anode

Talga Resources logo 2017Australian advanced materials technology company, Talga Resources, recently announced positive initial test results from the development of its graphene silicon lithium-ion anode in the UK.

The results are the first under Talga’s UK Government-funded “Safevolt” project - a Talga-led program run in conjunction with consortia partners, Johnson Matthey, the University of Cambridge and manufacturing research group, TWI.

Graphene Flagship partners design graphene-based phase modulators for faster mobile technology

Graphene Flagship Partners at the National Inter-University Consortium for Telecommunications (CNIT) in Italy, IMEC in Belgium and University of Cambridge in UK have designed and tested a graphene-based phase modulator that reportedly outperforms existing silicon-based ones.

Modern optical data and telecommunications employ phase modulators to increase the amount of data relayed and data rate efficiency, i.e. the speed at which information is relayed. Phase modulators traditionally work by grouping several bits of information into fewer symbols, or packets, reducing the overall size, or spectral width. The smaller the spectral width, the higher the data rate efficiency. However, this efficiency is reaching a maximum with silicon based devices, and so a novel solution is needed to bridge the gap between the increase in demand for data and the efficiency in transmitting it.

Versarien provides updates on several energy storage R&D fronts

Versarien LogoVersarien, the advanced materials engineering group, has provided an update on its activities in relation to graphene-enhanced power storage devices like batteries and supercapacitors. The primary goal of incorporating graphene into these devices, Versarien says, is to significantly increase power storage capacity and reduce charging times.

Versarien has been working with WMG (Warwick Manufacturing Group) and their partner companies and scientists at the universities of Warwick and Cambridge to collaborate on the production of power storage devices such as batteries and supercapacitors using Versarien's proprietary Nanene graphene nano platelets. Significant advances have been made through incorporating the Company's high quality graphene into these devices and the Company looks forward to commercial products becoming available in due course.

Talga to participate in ‘Faraday Battery Challenge’ program

Talga Resources logo 2017Australia-based Talga Resources and its UK subsidiary Talga Technologies recently announced collaboration agreements to commence three UK Government Faraday Challenge battery programs. The execution of formal agreements follows the awarding of the grants under Faraday, a £246 million UK Government commitment over the next four years into battery development for automotive electrification. The initiative will encompass cell manufacture, modules, battery pack design/assembly and vehicle applications, and follows an undertaking by the UK Government to place a ban on new petrol and diesel engines by 2040.

Talga’s participation in the funding program of Innovate UK, the government development body, follows successful tests by Talga of its natural carbon materials and technologies in Li-ion batteries. Talga, together with its consortia partners, secured significant funding support under the ‘Innovation’ aspect of Faraday. Talga will receive a 70% rebate against its eligible costs, including salaries, consumables, equipment and contractor expenses. Talga’s participation in the programs range from 12-24 months and development activities will be led from Talga Technologies Limited in Cambridge UK, utilizing the Company's Swedish high grade graphite and functionalized graphene processed at Talga’s test facility in Germany.
