美国科学家发现 ,通过调整温度 ,能够精确地控制一种钛硅酸盐材料中的孔洞大小 ,制造出精密的新型分子筛。一些晶体材料内部有着大量均匀的微孔 ,尺寸比孔洞小的分子能够穿过 ,而大分子不能穿过 ,因此可以起到分离不同分子的作用 ,这类材料被称为分子筛。科学家在英国《自然》? American scientists found that by adjusting the temperature, can accurately control the size of a hole in a titanosilicate material to create a sophisticated new molecular sieve. Some crystalline materials have a large number of uniform micropores inside, smaller than the hole size of the molecules can pass through, and macromolecules can not pass through, so you can play a role in the separation of different molecules, these materials are called molecular sieves.
