美研究人員研發出新物質

　　12月8日口譯文章：美研討職員研發出新物資,硬度比鉆石還高

　　北卡羅萊納州立大學的研討職員研發出一種名為“Q-碳”的新物資，其硬度比鉆石還高。

　　研討論文的第一作者傑伊·納拉楊在聲明中說：“天然界中，大概也就只有在某些行星的內核處能找到這類物資了。”

　　該物資被發明前，固體碳只有兩種分歧形態：石墨和鉆石。Q-碳不但硬度比鉆石高，位於低能量狀況下還能發光。這類特征使它特別實用於制作電子裝備堅固、通亮的表現屏。

　　要想天生Q-碳，研討職員需應用單脈沖激光沖激資料外面的無定形碳(即無晶體構造的碳)。

　　然後將資料冷卻，便可獲得Q-碳或碎鉆。這類鉆石可以用來制造醫用微型針頭，或是用來制作本事極度高溫的產業電子元件。

　　“這一系列進程都是在室平和通俗的大氣情況下完成的，咱們所用的激光也和眼部激光手術用的那種差未幾，”納拉楊說道。“是以，咱們不但能持續研發這類物資的新用處，並且研發本錢也相對於低廉。”

　　There is a new substance that is harder than diamond. It's called Q-carbon, and it was created by researchers at North Carolina State University.

　　"The only place it may be found in the natural world would be possibly in the core of some planets," Jay Narayan, lead author on the papers describing the work, said in a statement.

　　Before its discovery, there were two distinct forms of solid carbon: graphite and diamond. Q-carbon is not only harder than diamond, but also glows when exposed to low levels of energy. That could make it very useful for creating strong, bright screens for electronic devices.

　　Researchers created the Q-carbon by blasting material covered in amorphous carbon (i.e. carbon without a crystalline structure) with a single laser pulse.

　　They can cool the material to create either Q-carbon or tiny diamonds. Those diamonds could be used to build things such as microneedles for medical use, or electronics that can withstand extremely high temperatures for other industries.

　　"And it is all done at room temperature and at ambient atmosphere — we're basically using a laser like the ones used for laser eye surgery," Narayan said. "So, not only does this allow us to develop new applications, but the process itself is relatively inexpensive."
