Changes of a 65Ni25Cu10A1203 catalyst consisting of Ni-enriched and Cu-enriched alloys were investigated in the bulk and on the surface during the growth of nitrogen-doped carbon nanofibers （N-CNFs） by decomposition of a 50%C2I-I4/50%NH3 mixture using in situ X-ray diffraction （XRD） analysis, ex situ X-ray photoelectron spectroscopy （XPS） and transmission electron microscopy （TEM） techniques. It was shown that N-CNF growth at 450-650 ℃is accompanied by dissolution of carbon and nitrogen in the Ni-enriched alloy, whereas Cu-enriched alloy remains inactive. A correlation between nickel and copper surface concentrations and properties of N-CNFs in relation to the nitrogen content was found. It was demonstrated that phase composition of the catalyst during N-CNF growth determines the type of N-CNFs structure.

The nanocomposites based on cobalt oxide and nitrogen-doped carbon nanofibers (N-CNFs) with cobalt oxide contents of 10–90 wt% were examined as catalysts in the CO oxidation and supercapacity electrodes. Depending on Со3О4 content, such nanocomposites have different morphologies of cobalt oxide nanoparticles, distributions over the bulk, and ratios of Со3+/Co2+ cations. The 90%Со3О4-N-CNFs nanocomposite showed the best activity because of the increased concentration of defects in N-CNFs. The capacitance of electrodes containing 10%Со3О4-N-CNFs was 95 F/g, which is 1.7 times higher than electrodes made from N-CNFs.

In recent decades,meromictic ponds attract the attention of researchers in different directions,because here the character of the physical,chemical and biological processes differ from those of typical mixing waters(Kuznetsov,1970;Hutchinson,1969).In Transbaikalia widely distributed soda and salt lakes with different *** among them is Lake Doroninskoye,which has a pronounced stratification for a

为了获得2.15～1 500μm的相干光源,研究了CO激光在高质量非线性晶体ZnGeP2和GaSe中的混频效应。为了提高转换效率,在激光锁模方式下对CO激光器的二次谐波、和频和差频的产生进行了研究。结果显示,利用GaSe晶体和ZnGeP2晶体,调Q多谱线CO激光辐射的谱线内倍频效率分别大于0.3%和1.1%。采用ZnGeP2晶体进行倍频时,可调谐锁膜CO激光器的转换效率为12.5%。模拟结果显示,二次谐波与和频产生的输出光谱相同。相邻谱线下,和频和差频的产生过程中,基波和一次谐波可以分别在4.0～5.0μm和100～≥1 200μm(太赫兹范围)形成振荡。利用锁模CO激光器在ZnGeP2晶体中的混频效应,可以得到2.15～≥1 500μm的相干光源,同时转换效率可达到甚至高于12.5%。

采用水平区熔法生长了碲(Te)掺杂浓度(质量百分比)分别为0.05%,0.1%,0.5%,1%,2%的硒化镓(GaSe)晶体,并分别对掺杂浓度为0.01%,0.07%,0.38%,0.67%,2.07%的GaSe∶Te晶体的光学性能进行了表征。首次研究了GaSe∶Te晶体中刚性层声子模式的转换。吸收光谱测试结果表明:当Te掺杂浓度小于0.38%时,振动中心位于0.59 THz附近的E'(2)刚性模式吸收峰强度可达最大值,这一过程与GaSe∶Te晶体光学性能的提高密切相关。但Te掺杂浓度的进一步提高会导致E'(2)刚性模式吸收峰强度逐渐减弱,当Te掺杂浓度为1%时,E'(2)刚性模式吸收峰基本消失。这两个过程与GaSe∶Te晶体光学质量的下降密切相关。因此,E'(2)刚性模式吸收强度达到最高时对应的掺杂浓度即是GaSe∶Te晶体中Te的最佳掺杂浓度,光整流产生太赫兹过程证实了此结论的正确性。
