美国特拉华大学化学工程学教授亨利C.富利和杜邦公司的工程研究员马克B.希夫利特合作,利用超声波制成一种坚固的纳米孔碳素膜,氧分子透过膜孔的速度比氮分子快30倍。这种陶瓷膜经进一步开发后可能用于工业气体分离和蛋白质液体培养基的富集,还可能用于催化和燃料电池。这?.. Henry C. Foley, a professor of chemical engineering at the University of Delaware, and Mark B. Schmidt, an engineering researcher at DuPont, used ultrasound to make a solid nano-porous carbon membrane through which oxygen molecules flow 30 times faster than nitrogen molecules. This ceramic membrane, after further development, may be used for industrial gas separation and enrichment of protein broths, possibly for catalysis and fuel cells. This?..
