Herein, graphite fibres were prepared from polyimide (PI) fibres by doping varying contents of graphene oxide (GO) into polyimide (PI) fibres through a carbonization and graphitization process. By in situ polymerization, GO/polyamic acid (PAA) was synthesized and used for preparing GO/PI fibres via dry-jet wet spinning.
Elecjet has created a new graphene-based fast charging USB-C battery pack which has been launched via Kickstarter this week and is capable of being charged from flat to full in 20 minutes. Watch the demonstration video below to learn more about the battery pack …
A group of researchers at Technical University of Denmark, National Physics Laboratory in UK and Spanish Graphenea, explain in a recent review paper why the graphene industry needs better and faster electrical characterisation methods.
Batteries are the engine room for so much of the modern world, from smartphones to laptops and weird new scooters to the emerging fleets of autonomous trucks. So there are plenty of folks with an interest in pushing battery technology forward, and 2017 brought a raft of exciting breakthroughs aimed at making them safer, longer-lasting, faster-charging and more cost effective. Here’s the best of the bunch.
Advanced materials company, First Graphene Limited (FGR), has provided an update on its development of the graphene based FireStop™ fire retardant material.
Development of the FireStop™ material is being conducted in conjunction with the University of Adelaide as part of the Company’s participation as a Tier 1 participant in the ARC Research Hub for Graphene Enabled Industry Transformation.
In a successful collaboration between the Graphene Flagship and the European Space Agency, experiments testing graphene for two different space-related applications have shown extremely promising results. Based on these results, the Flagship are continuing to develop graphene devices for use in space.
Researchers from Pondicherry University, Puducherry and SRM University, Chennai have recently demonstrated a novel device made of Nickel/ Nickel oxide (Ni/NiO) and graphene that could be used to store hybrid-energy.
The rising use of alternative and renewable energy sources also increases the need to store enormous amounts of energy. Unlike fossil fuels, which can be burnt when there is a need for the energy, renewable sources, like solar and wind, is only available intermittently. Using these sources efficiently requires devices like batteries and supercapacitors to store the energy when it is generated. However, battery technology, unlike other technologies, has not seen huge advancements.
On December 12, Tunghsu Optoelectronic signed Agreement on Cooperation for Jointly Building Smart Cities with the related institutions in Japan, Thailand, Malaysia, Indonesia and Mongolia to form a strategic partnership. Meanwhile, Tunghsu Optoelectronic also signed an Exclusive Agency Contract and Sale Contract of more than RMB 10 million with Okura Co., Ltd. for Graphene Thermolysis High Power LED Lights.
Researchers at Columbia Engineering, experts at manipulating matter at the nanoscale, have made an important breakthrough in physics and materials science, recently reported in Nature Nanotechnology. Working with colleagues from Princeton and Purdue Universities and Istituto Italiano di Tecnologia, the team has engineered “artificial graphene” by recreating, for the first time, the electronic structure of graphene in a semiconductor device.
An international group of scientists from MEPhI, ITMO University and Hosei University (Tokyo, Japan) has begun working on a hybrid two-dimensional structure based on graphene and quantum dots with controlled optic and photoelectric properties for use in solar batteries. The project will result in a prototype solar battery more efficient than existing batteries.
