Dec. 18, University of Manchester: Scientists at the University of Manchester have developed a new way of printing graphene electronics that could be cheaper and faster than standard techniques. Current conductive inks use nanoparticles, which can be expensive or prone to odixation, for their high electrical conductivity. However, the U of M team found that using a material called dihydrolevogucosenone (known as Cyrene) is non-toxic, environmentally friendly, and can provide higher concentrations and conductivity.
