Waterproof graphene electronic circuits

ScienceDaily.com: Nanotechnology News - Wed, 01/30/2019 - 19:38
Water molecules distort the electrical resistance of graphene, but a team of researchers has discovered that when this two-dimensional material is integrated with the metal of a circuit, contact resistance is not impaired by humidity. This finding will help to develop new sensors -- the interface between circuits and the real world -- with a significant cost reduction.

Graphene: Large, stable pieces of graphene produced with unique edge pattern

ScienceDaily.com: Nanotechnology News - Tue, 01/29/2019 - 19:19
Graphene is a promising material for use in nanoelectronics. Its electronic properties depend greatly, however, on how the edges of the carbon layer are formed. Zigzag patterns are particularly interesting in this respect, but until now it has been virtually impossible to create edges with a pattern like this. Chemists and physicists have now succeeded in producing stable nanographene with a zigzag edge. Not only that, the method they used was even comparatively simple.
