Graphene is a wonder material with extraordinary electrical and thermal conductivity but it is ___. A. cheap and widely available B. in the research and development stage and its cost is very high C. easy to produce D. not very useful ...
During this decade, graphene which is a thin layer of carbon material along at ease with synthesis and functionalization has become a hot topic of research owing to excellent mechanical strength, very good current density, high thermal conductivity, superior electrical conductivity, large surface area...
aGraphene is an ideal material for the construction of FET biosensors because it is a zero-band gap semiconductor, and the band gap can be tuned by surface modification. Graphene是理想的材料为FET生理传感器的建筑,因为它是零带空白半导体,并且带隙可以由表面修改调整。 [translate] ...
Graphene(石墨烯) is a type of mineral, which experts often call 'The Material of the 21st Century' because of its special properties. Some U.S. companies are already using graphene for new technology products. Graphene is often described as a one-atom-thick layer of carbon. The material ha...

This is possible thanks to a wonder material called graphene.这里一句话里出现了两个动词啊,is是动词而thanks也是动词,这不是重复了吗。 网校学员Jas**在学习流利商务口语初中高级连读【2月班】时提出了此问题,已有1人帮助了TA。 网校助教 Funny助助...
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?
(1)词义猜测题。根据第二段Graphene,a material made from a single layer of carbon atoms,is a good electrical conductor resistant to heat and acids.But a working graphene semiconductor which can be controlled to conduct or separate electricity at will,
Graphene, a single-atom-thick sheet of graphite, is a new material which combines aspects of semiconductors and metals.
