Mixing a little dry ice and a simple industrial process cheaply mass-produces high-quality graphene nanosheets, researchers report. Mixing a little dry ice and a simple industrial process cheaply ...

Graphene, a new class of two-dimensional carbon nanostructure, has attracted tremendous attention from both the experimental and theoretical scientific communities in recent years 1. This unique ...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers have ...

we reported on a strategy to 'stitch' reduced graphene oxide (rGO) nanosheets into ultra-strong and highly conductive graphene films using only small amounts of cross-linker. Advancing their previous ...

Cobalt oxide has proven fruitful, but there are other graphene analogs that the team ... Transformation Route to Atomically-thick Co3O4 Nanosheets Realizing Enhanced Lithium Storage Performance" ...

Among several techniques adopted to synthesize graphene from graphite, the liquid phase exfoliation methods have been found to be facile and cost-effective. Yet, the use of strong solvents and ...

They "cooked" cannabis bark into carbon nanosheets and built supercapacitors "on a par with or better than graphene" - the industry gold standard. Electric cars and power tools could harness this ...

Among several techniques adopted to synthesise graphene from graphite, the liquid phase exfoliation methods have been found to be facile and cost-effective. Yet, the use of strong solvents and ...

Waterloo researchers tackled that problem by creating the world’s first all-graphene ink by engineering graphene nanosheets that can disperse in water while still maintaining conductivity. In addition ...

oxide or graphene nanosheets layer by layer. Both processes require high temperatures of around 3000 °C and processing times of an hour. In CVD, the required temperatures are lower (between 700 to ...

To form large-area graphene nanosheet films, a solution of solvent and the edge-carboxylated graphene nanosheets was cast on silicon wafers 3.5 centimeters by 5 centimeters, and heated to 900 degrees ...
