Knitting Severed Spinal Cords With Graphene Ribbons

A new material made of graphene nanoribbons and a common polymer might help knit damaged or even severed spinal cords. The nanoribbons are highly soluble in polyethylene glycol (PEG), a biocompatible polymer gel used in surgeries, pharmaceutical products, and in other biological applications. When the nanoribbons have their edges functionalized with PEG chains and are […]

Graphene-Based Interfaces Do Not Alter Target Nerve Cells

Researchers have successfully demonstrated how it is possible to interface graphene – a two-dimensional form of carbon – with neurons, or nerve cells, while maintaining the integrity of these vital cells. The work may be used to build graphene-based electrodes that can safely be implanted in the brain, offering promise for the restoration of sensory […]

3D White Graphene Could Keep Electronics Cool

Three-dimensional structures of boron nitride might be the right stuff to keep small electronics cool. Rice University researchers Rouzbeh Shahsavari and Navid Sakhavand have completed the first theoretical analysis of how 3D boron nitride might be used as a tunable material to control heat flow in such devices. In its two-dimensional form, hexagonal boron nitride […]

Graphene Film Cools Electronics 4 Times Better Than Copper

An effective method for cooling electronics using graphene-based film has been developed by researchers at Chalmers University of Technology. The thermal conductivity capacity of the film is four times greater than copper’s. Not only that, but the graphene film can be attached to electronic components made of silicon. This gives favourable performance compared to typical […]
