carbon 有一个formate 系graphite 佢用左3粒slectron 去form covalent bond with other carbon 由于系3个bond 佢成为左一个plane 最后个粒electron 就系plane 同plane之间自由游离 由于lee 粒electron 系free electron 所以it conduct electricity
We know that every aspect of life there are carbon reduction factor, save water, electricity, gas, can reduce the use of coal is not only a good tradition, but also the embodiment of the environmental protection consciousness, we must start from the little things that make life more green, ...
and can be dyed(上色) different colors or printed attractive patterns on.The woven network is linked to a temperature-sensitive sensor on the back of the paper, which is made from aspecial material called “ grapheme oxide", a carbon-based material which cannot conduct electricity(导电)at room...
Why do covalent compounds not conduct electricity? Why is graphite a good conductor whereas diamond is not? (Both contain infinite lattices of covalently bound carbon atoms) Why does diamond have a lower entropy than graphite? Why do metals conduct heat and electricity?

1. Low carbon city experiments Since the Kyoto Protocol was ratified in Europe in 2002, cities across the region have introduced local carbon dioxide reduction targets and climate action plans. This has led to a proliferation of low carbon experiments in many European cities. These experiments prov...
To ensure the realization of carbon neutrality and emission peak, the Chinese government promulgated the pilot policy for an emissions trading scheme (ETS) in 2011 and gradually expanded the range of the pilot program. However, it has not been systematically studied whether this policy can achieve...
Researchers have developed a new type of fiber, which has both the flexibility of cotton and the conductivity of polyaniline polymer.
