Making graphene in your kitchen
Graphene has been touted as a wonder material—the world's thinnest substance, but super-strong. Now scientists say it is so easy to make you could produce some in your kitchen.
Researchers improve performance of III-V nanowire solar cells on graphene
(Phys.org) —Imagine a field of small wires—standing at attention like a tiny field of wheat—gathering the Sun's rays as the first step in solar energy conversion.
Proposed graphene cardboard has highly tunable properties
Quasi-particle swap between graphene layers
Belgian scientists have used a particle physics theory to describe the behaviour of particle-like entities, referred to as excitons, in two layers of graphene, a one-carbon-atom-thick honeycomb crystal. In ...
Graphene origami opens up new spintronics features
Two teams independently find that adding vibration helps couple light to graphene
Graphene 'onion rings' have delicious potential
Concentric hexagons of graphene grown in a furnace at Rice University represent the first time anyone has synthesized graphene nanoribbons on metal from the bottom up—atom by atom.
Imperfect graphene renders 'electrical highways'
(Phys.org) —Just an atom thick, 200 times stronger than steel and a near-perfect conductor, graphene's future in electronics is all but certain. But to make this carbon supermaterial useful, it needs to ...
Jagged graphene edges can slice into cell membranes
(Phys.org) —A collaboration of biologists, engineers, and material scientists at Brown University has found that jagged edges of graphene can easily pierce cell membranes, allowing graphene to enter the ...
Researchers fine-tune the sensitivity of nano-chemical sensor
Researchers have discovered a technique for controlling the sensitivity of graphene chemical sensors.
