学校基建修缮工程内部造价管理探析

学校基建修缮工程内部造价管理中存在随意变更、现场签证不实、计价错漏等问题,对此内部造价管理部门及管理人员要建立并规范内部造价管理程序,从内部造价管理主过程加以控制,以夯实内部造价,提高学校基建投资效益。     

离子液介质中生物催化与生物转化的研究进展

Ionic liquids have negligibly low vapor pressure, high stability and polarity. They are regarded as green solvents. Enzymes, especially lipases, as well as whole-cell of microbe, are catalytically active in ionic liquids or aqueous-ionic liquid biphasic systems. Up to date, there have been many reports on enzyme-exhibited features and enzyme-mediated reactions in ionic liquids. In many cases, remarkable results with respect to yield, catalytic activity, stability and (enantio-, regio-) selectivity were obtained in ionic liquids in comparison with those observed in conventional media. Accordingly, ionic liquids provide new possibilities for the application of new type of solvent in biocatalytic reactions.
