Drug-design Lessons Applied To Production Of Industrial Minerals
2013-06-18 08:46:22

Rice University Taking a page from computer-aided drug designers, Rice University researchers have developed a computational method that chemists can use to tailor the properties of zeolites, one of the world's most-used industrial minerals. The research is available online and will be featured on the June 21 cover of the Royal Society of Chemistry's Journal of Materials Chemistry A. The method allows chemists to work backward by first considering the type of zeolite they want to make...

Zeolites (Greek, zein,"to boil";lithos,"a stone") are minerals that have a porous structure. There are about four dozen recognized naturally occurring zeolite minerals and as many or more synthetic varieties. They are basically hydrated alumino-silicate minerals with an "open" structure that can accommodate a wide variety of positive ions, such as Na+, K+, Ca2+, Mg2+ and others. These positive ions are rather loosely held and can readily be exchanged for others in a contact solution. Some of...
