Preparing different phases of Mg-Li-Sm alloys by molten salt electrolysis in LiCl-KCl-MgCl2-SmCl3 me
Different phases of Mg-Li-Sm alloys were prepared by galvanostatic electrolysis in LiCl-KCl-MgCl2-SmCl3 melts at 670 ℃.The electrolysis process and phase contr
Density functional theory (DFT) calculations were carried out on the compounds Cp2Ln-guan for Ln=Y, Lu, Yb, Dy and Gd, [guan=(iPrN)2CN(iPr)2]. The results were
土壤蓝藻结皮在干旱和半干旱地区广泛分布.沙埋是生长在流动沙丘表面的植物面临的重要的环境因子.实验研究了温室条件下干燥沙子不同掩埋时间(0,5,10,15,20,30天)和深度(0,0.2,0.5,1,2cm)对人工藻结皮生物量、叶绿素荧光活性和胞外多糖的影响.结果表明:大体上随着沙埋时间的延长和深度的增加人工藻结皮的F_v/F_m值和胞外多糖含量逐渐降低,但是在20天和30天沙埋处理之间,两者在不
As a mixed conductor,LaSr3Fe3O10-δ with triple layer perovskite intergrowth structure can be used as an oxygen separation membrane material and cathode materia
The phase evolution,microstructure and magnetic properties of Nd9-xYxFe72Ti2Zr2B1s(x=0,0.5,1,2)nanocomposite ribbons were investigated.It was found that substit
采用化学混凝法,以MgSO4为混凝剂、阴离子聚丙烯酰胺为助凝剂,分别对棉布印染过程中排放的活性染料废水进行实验研究.结果表明,pH对脱色率有较大的影响,当pH＞12.0时,脱色率基
Fe/Cu/Ce modified coal-based activated carbon (AC) was prepared by the sol-gel method, and the effect of FedCu/Ce on catalytic properties of Fe/AC, Fe-Cu/AC and
