Making graphene from waste

We can now make graphene from sources that are inexpensive, including cookies, dog feces and other waste.

See the vid below for demonstration, or see a pretty good source article from Guardian on the whole story.

New 2D material on the scene

MoS2, molybdenum disulfide may not have the best name to it yet, but seems promising with its electrical properties.

A few videos on graphene

This is with Andrew Geim, one of the two awarded the Nobel prize for experiments in graphene.

And the second with Nobel prize winner Konstantin Novoselov

Quick charge and discharge with graphene

With use of graphene in batteries, we could have 10x faster charge and discharge. Those are the aspects regular batteries are not handling very well today. Especially those in electric cars and mobiles would benefit from this development big time.

See the article for more info.

Graphene properties change based on where it is

According to a few articles, chemical and physical properties of graphene change based on what material is near it. Since graphene is so thin, the bonds btw atoms can be easily affected by the surroundings.

This is useful in creating various patterns for sensors. The other dimension is that it behaves differently when more layers of graphene are added as well.
