Density-functional theory calculations are carried out for a biomimetic dimanganese complex,[H2O(terpy)MnⅢ(μ-O)2MnⅣ(terpy)OH2]3+(1,terpy=2,2:6,2"-terpyridine),which is a structural model for the oxyge
Within the framework of statistical mechanics,classical density functional theory(cDFT) has been developed as an approach to study structural and thermodynamic properties of ionic liquids.

Polycyclic aromatic hydrocarbons(PAHs) is one kind of the most widespread atmospheric pollutants and are very dangerous because many of them are potent mutagens and carcinogens [1].
土壤生物炭固碳是当前最有潜力的减排方式之一.土壤性质特别是pH对其固碳减排效果有重要影响[1].我国耕地土壤的27 %为红壤(pH≦5.5)[2],酸沉降及过度施用氮肥则加剧土壤酸化[3].迄今,有关酸性土壤生物炭固碳减排效果及影响因素尚不清楚,为此探讨了影响红壤地区土壤生物炭固碳减排的因素及其机制.
Soil heavy metal contamination through anthropogenic activities,in particular mining activities,is a major environmental concern,and the ecological risk associated with heavy metals is increasing.
随着电子信息等高科技产业的迅猛发展,废弃电子电器已成为增速最快的危险废物.据联合国绿色和平组织估计,全世界每年产生的电子垃圾高达2000-5000万吨,且以每年约4 %的速率增加.电子垃圾中含有大量的可继续使用的电子电器元器件及金属和非金属,因此具有极高的回收利用价值.
