A sandwich of two graphene layers can conduct electrons without resistance if they are twisted at a ‘magic angle’’, physicists have discovered. The finding could prove to be a significant step in the decades-long search for room-temperature superconductors.
Researchers at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory are part of a scientific collaboration that has identified a new electrocatalyst that efficiently converts CO2 to carbon monoxide (CO), a highly energetic molecule.
Fraunhofer scientists have developed biosensors with graphene electrodes, produced cheaply and simply by roll-to-roll printing. A system prototype for mass production has already been established. This may change the current situation in which cell-based biosensors can be quite expensive to make, which often prevents them from being used. Cost factors for sensors that perform measurements electrically are the expensive electrode material and complex production.
Scientists from CSIR–Central Electrochemical Research Institute (CSIR-CECRI) and CSIR–Central Salt and Marine Chemicals Research Institute (CSIR-CSMCRI) in India have collected discarded lithium-ion batteries and created reduced graphene oxide from them. The material reportedly showed high specific capacity at low current, making it an ideal material for next generation high-performance supercapacitors.
Researchers at the Korean Advanced Institute of Science and Technology (KAIST) have developed a graphene-based aqueous hybrid capacitor that is stable, safe and boasts high energy and power densities, in addition to recharging in under 30 seconds.
The Mobile World Congress in Barcelona is a major annual event for the international mobile telecoms community…

Foldable phones will be on the market within five years, according to the Graphene Flagship programme. As Ivor Bennett reports, the miracle material will revolutionise not only mobiles but medicine too.

Scientists at UCL have explained for the first time the mystery of why adhesive tape is so useful for graphene production. The study, published in Advanced Materials, used supercomputers to model the process through which graphene sheets are exfoliated from graphite, the material in pencils.

Many of you will know about graphene and how it has been touted as the new wonder material that will change the face of many nanotechnology applications. Whilst graphene is the most promising in terms of its commercial potential, there are a host of other 2D materials out there with amazing properties that are still relatively unheard of in the scientific community. For clarification, a material is considered to be 2-dimensional when they are a single atomic layer with their electrons confined to 2-dimensional space.

Sir Kostya Novoselov told the BBC that many scientists were dependent on funding from Europe and the UK needed to be much more proactive in supporting technology companies if it wanted to compete with China.
