The composite powders consisted of Si, Ni, Ag and a series of Si-Ni alloys. The SEM and TEM results showed that the composite powder consisted of clusters with space and network structures. The composite electrode exhibited higher reversible capacity and the initial columbic efficiency was up to 87 %, which was much higher than that of the pure Si electrode.

XRD结果表明，复合材料中含有Si、Ni、Ag以及一系列Si-Ni合金相；SEM及TEM结果表明，复合材料呈现网格状的团簇结构，而且有一定的层状厚度；电化学测试显示，该材料电极具有较高的首次嵌/脱锂容量，首次效率达87%，较纯硅粉电极有了很大的提高。

When Ni〓 was equatorially coordinated by four nitrogen atoms from the same amine ligands such as ethylenediamine and N-methylethylenediamine, arenedisulfonates did not axially coordinated to Ni〓.

Ni〓与同样的胺配体（如乙二胺、N-甲基乙二胺）的四个氮原子在赤道平面配位后，芳烃二磺酸根离子并没有在轴向与Ni〓配位，水分子仍然占据轴向的位置。

Using pure Ti and Ni powders, a promising artificial bone material, nearly equiatomic stoichiometry Ti-Ni shape memory alloys porosity was prepared by combustion synthesis method.

The Ni-Fe and Mg-Al-Fe-LDH show paramagnetism at normal temperature, the calcined samples of LDHs show super-paramagnetism. The magnetization increases with the higher Fe~(3+) content and is independent of the crystal structure of LDHs. Magnetization of the calcinates of Ni-Fe-LDHs is higher than the Mg-Al-Fe-LDHs.3. Two novel SFME systems were found for the first time, that is furaldehyde/DMF/water and furaldehyde/ethanol/water system.

结果表明，Ni-Fe和Mg-Al-Fe型LDHs本身及其煅烧产物在常温下均呈现顺磁性，其煅烧产物均呈现超顺磁性；同类LDH中其煅烧产物的磁性大小与Fe~(3+)含量成正比而与LDH的晶体结构无关，Ni-Fe LDHs及其煅烧产物的磁性强于Mg-Al-Fe LDHs及其煅烧产物，。3。

Methods Twenty-four extracted teeth block were bonded with Ni-Cr alloy and 24 resin block were bonded with Ni-Cr alloy by two kinds of adhesive material. Those were Gluma comfort bond and Single bond. Those bonding complexes were stored in normal saline solution for 72 hours.
