查询词典 ions

Through the calculating of doping materials, we can see electrons are easy to transation or transfer, which strengthens the conduction properties of materials. Especially the stability of materials doping with Mn or Al is more strong, and the ionizing energy is more lower. These indicate that the electrons in the outest orbit are easier to lose, that is to say the Li+ ions are easier to imbed into materials. The discharge voltage of material doping with Co decreases, the oxidization of electrolyte is more difficult, and the cycling performance is improved.

通过对掺杂材料的计算可见掺杂后电子更容易跃迁或转移，增强了材料的导电性能，其中掺锰和掺铝的材料稳定性更强，电离能降低，说明失去最外层电子更容易，也就是说锂离子在材料中嵌入和脱出更加容易；掺钴之后材料的放电电压降低，电解液氧化的可能性减小，循环性能得到改善。

Results show that the iron acts as active site in the film which makes the overpotential lower, and changes the rate-limiting from primary discharge of OH - ions to the recombination of oxygen atom.

By controlling the potential of the electrolyte solutions,this technique can be employed in studies formation of DNA strand breaks.CT-DNA was cleaved by adding amounts of CuL or NiL complex in the absence of chemical reagent when appropriate electrode potential(sufficiently negative or positive to reduce or oxidate metal ions) was applied.

根据获得的实验结果，CuL或NiL存在下，电解溶液的电位合适时(足够负或足够正的电位，保证金属离子的还原或氧化)，不需要加入额外的氧化剂或还原剂，同样可以切割小牛胸腺DNA，CuL劈裂能力强于NiL配合物。
