据《MIT技术评论》杂志网站8月16日报道,美国莱斯大学的科学家日前通过计算发现,一种新形式的碳具有极高的强度和硬度。这种新形式的碳被称为碳炔,也是碳的一种同素异形体。天文学家一直认为他们曾在太空中发现过碳炔的信号,化学家则为是否能在地球上合成这种材料争辩了几十年。直到几年前,有人合成出了44个原子长的碳炔链,才
According to MIT Technology Review’s website, August 16, scientists at Rice University in the United States recently found that a new form of carbon has very high strength and hardness. This new form of carbon is called acetylene and is an allotrope of carbon. Astronomers have long believed they have been signaling the presence of alkyne in space, and chemists have argued for decades whether or not they can synthesize it on Earth. Until a few years ago, someone synthesized a long chain of 44 carbon atoms alkyne chain, only
