What is graphene?The article offer information on graphene, an ultrathin layer of graphite.Environmental Engineering
There's been a lot of talk about graphene over the past few years. But what is it exactly? And why are people so excited about it? Why should you care?
Graphene is a one-atom-thick layer of carbon atoms arranged in a hexagonal lattice. It is the building-block of Graphite (which is used, among others things, in pencil tips), but graphene is a remarkable substance on its own - with a multitude of astonishing properties which repeatedly earn...
Graphene is known as the material of the future due to its excellent properties and multiple applications. Discover its full potential!
Graphene is one of the most promising semimetals on the face of the Earth, though, many people still have no idea as to what it is. Simply put, graphene is a super-thin material that is nonetheless remarkably strong. Here's how it works, and what it coul
Graphene is a flat hexagonal lattice of carbon atoms, just one atom thick. It is a form of carbon related to carbon nanotubes and buckyballs (C60). Although it has always occurred naturally, it is only recently that it has been isolated and it’s individual properties examined. It is now...
It is a material made of a single layer of carbon atoms. [解析]细节理解题。题干意为:石墨烯是一种新型材料吗?它是什么?(不超过15个词)根据第四段中“Graphene, first discovered in 2004, is a material made of a single layer of carbon atoms”(在2004年发现的石墨烯是一种由单层碳原子组成的...
Graphene is a single layer of graphite or carbon atoms arranged in a honeycomb lattice. More importantly, it is one of the most promising nanomaterials ever to be discovered. Graphene is the world's thinnest, strongest and most electrical and thermal conductive material. ...
