分子运输机

美国物理学家们开发了一种可以沿着晶体表面运输二氧化碳分子的"分子运输机"。分子搭在一种名叫AQ (anthraquinone)的有机化合物上面,这种有机化合物能承载住分子并运送它们至10nm以外,直至按要求将分子卸载。研究者们相信,这种现象可以为显著提高表面催化剂的效率提供动力,或者还可以促进半导体器件的处理。

Molecular carrier is on the straight and narrow (Jan 18)

A "molecular carrier" that can transport carbon dioxide molecules in straight lines across a crystalline surface has been developed by physicists in the US. The molecules hitch a ride with an organic compound called anthraquinone (AQ), which grabs hold of them and carries them over distances of about 10 nm before dropping them on request. The researchers believe that this phenomenon could be harnessed to boost the performance of surface catalysts or to improve the processing of semiconductor devices (Sciencexpress 10.1126/science.1135302).
