GMG sends graphene aluminium-ion batteries to customers for testing

Graphene Manufacturing Group (GMG) has announced that its graphene aluminium-ion batteries ("G+AI Battery") 2032 type coin cell prototypes have been sent to a number of prospective customers around the world.

GMG reports that coin cell testing to date has demonstrated that the GMG 2032 type G+AI Battery coin cell prototypes are fully rechargeable in several seconds, retain capacity for several thousand charge and discharge cycles, are non-flammable, and are relatively non-toxic and almost fully recyclable. These characteristics compare favorably against typical rechargeable Lithium-Ion 2032 type coin cells which take 3-6 hours to recharge, are toxic and can be quite harmful if ingested, are difficult to recycle, are flammable under certain conditions, and degrade more rapidly in performance.

Researchers stabilize the edges of graphene nanoribbons and measure their magnetic properties

Researchers at Lawrence Berkeley National Laboratory (Berkeley Lab) and UC Berkeley have developed a method to stabilize the edges of graphene nanoribbons and directly measure their unique magnetic properties.

The team, co-led by Felix Fischer and Steven Louie from Berkeley Lab’s Materials Sciences Division, found that by substituting some of the carbon atoms along the ribbon’s zigzag edges with nitrogen atoms, they could discretely tune the local electronic structure without disrupting the magnetic properties. This subtle structural change further enabled the development of a scanning probe microscopy technique for measuring the material’s local magnetism at the atomic scale.

New graphene-based neural probes improve detection of epileptic brain signals

Researchers the UK and Spain have demonstrated that tiny graphene neural probes can be used safely to improve our understanding of the causes of epilepsy.

The graphene depth neural probe (gDNP) consists of a millimeter-long linear array of micro-transistors imbedded in a micrometer-thin polymeric flexible substrate. The transistors were developed by a collaboration between The University of Manchester’s Neuromedicine Lab and UCL’s Institute of Neurology along with their Graphene Flagship partners.

Researchers develop graphene-biosensors for brain machine interfaces

Researchers at the University of Technology Sydney (UTS) have developed a novel graphene-based biosensor, set to drive new innovations in brain-controlled robotics.

The biosensor adheres to the skin of the face and head in order to detect electrical signals being sent by the brain. These signals can be translated into commands to control autonomous robotic systems. The sensor, made of epitaxial graphene grown onto a silicon carbide on silicon substrate, overcomes the major challenges of corrosion, durability and skin-contact resistance.
