Graphene is a flat monolayer of carbon atoms, arranged in a two-dimensional hexagonal structure, with extraordinary electrical, thermal, and physical properties. Moreover, the molecular structure of graphene can be chemically modified with molecules of interest to promote the development of high-perform...

There are a variety of situations that may call for the implantation of electrodes in the brain, ranging from thetreatment of neurological conditionsto possibly evenrestoring the function of paralyzed limbs. A newly-developed hydrogel could someday replace such electrodes, allowing for better functional...
"In your body, you don't see many surfaces acting like plastic or glass," said Alex Savchenko, a research scientist at the University of California San Diego School of Medicine. "Our hearts are extremely good at conducting electricity. In the brain, it's electric conductivity that allows me...
Use of graphene in a transistor configuration offers an alternative to metal electrodes for the recording of ultraslow neural potentials that occur in neurologic diseases. Jed A. Hartings Article|31 December 2018 High-resolution mapping of infraslow cortical brain activity enabled by graphene microtrans...
S Liu,D Akinwande,D Kireev,JAC Incorvia 摘要: Analog neuromorphic computing systems emulate the parallelism and connectivity of the human brain, promising greater expressivity and energy efficiency compared to digital systems. Though many devices have emerged as candidates for artificial neurons and ...

INBRAIN’s BCI platform leverages the exceptional properties of graphene, a material made of a single layer of carbon atoms. Despite being the thinnest material known to science, graphene is stronger than steel and possesses a unique combination of electronic and mechanical properties that make it ...
On the contrary, its derivatives, such as graphene oxide (GO) and reduced graphene oxide (RGO), have excellent properties and can be easily produced in large quantities. GO/RGO nanohybrids with porphyrins were shown to possess great potential in the field of photocatalytic hydrogen production, ...
Computers are huge calculators with numerous switches with a value of 0 or 1. They use several of these binary systems to perform calculations very fast. But, in other respects, computers are not so efficient. When compared to a standard microprocessor, the human brain uses less energy to rec...
