each carbon atom bonds to four others in a dense network that makes the material the hardest substance known. But in graphite, each carbon atom bonds only to three others in a much looser arrangement of layers, each of which is weakly bonded to neighboring layers. Because individual layers of...
The carbon nano- tube film which is supported in the base substance, lines upThis invention relates to a process for preparing a substrate-supported aligned carbon nanotube film including: synthesizing a layer of aligned carbon nanotubes on the substrate capable of supporting nanotube growth, ...
He was a very clever scientist, but he had a strange habit of tasting a little of every substance he studied. This risky practice finally caught up with him. In 1 786,he was found dead in his laboratory, surrounded by a...

英文:Activated carbon removes pollutants from water by means ofadsorption. 吸收(absorption):指物质穿透或进入另一物质内部的过程,典型应用包括液体被多孔物质吸收、光或能量的吸收等。例如: 中文:吸光剂为对可见光有较强吸收作用的深色物质。 英文:The lightabsorberis a dark substance having strongabsorptionof...
Silica: Named based on its function as carbon black. It is incorrect to use the term silica to refer to a white substance with carbon black properties. Let's talk about the difference between "carbon" and "charcoal". Why is there a distinction between using "carbon" and "charcoal" in ph...
