论残疾人非制度化利益表达

残疾人通常根据其政治、经济、精神和社会保障等利益需要进行利益表达。当残疾人的利益表达机制不完善、缺乏利益表达意识、社会利益输出不平衡等因素造成制度化利益表达受阻,残疾人只能无奈地选择非常规的、非制度化利益表达方式。通过健全残疾人社会保障服务体系、保证残疾人制度化利益表达渠道畅通、引导残疾人合理运用网络新媒体进行利益表达,是规避由非制度化利益表达造成的社会不和谐因子的有效途径。     

论我国没收程序的没收对象问题

我国违法所得没收的特别程序规定的没收对象是违法所得及其他涉案财产,我国程序法规定的没收对象与实体法规定的没收对象有所不同,也与国际公约所规定的犯罪所得不一致.在分析违法所得与犯罪所得区别的基础上,认为我国刑事诉讼法新增违法所得没收程序的没收对象应该进一步明确和完善.     

Electrochemical properties of some cobalt antimonides as anode materi-als for lithium- ion batteries

Some cobalt antimonides have been prepared and studied as the candidate anode materials for lithium ion batter-ies. Reversible capacities of 424,423 and 546 mA·h·g-1 were measured at the first cycle for as-solidified CoSb2, CoSb3 and annealed CoSb3 respectively. A low lithium ions diffusion coefficient in the order of 10-16 m2·s-1 was estimated from the coulometric titration measurements in the annealed CoSb3 electrode. It was found that the electrochemical properties of fine powders are significantly better than coarse powders. However the SEM picture shows that the nano-sized CoSb3 powders gathered to larger granules, which worsens somewhat the capacity retention of the nano-sized materials, although the volume capacities of the annealed and ball milled CoSb3 remain near twice of that of graphite after 50 cycles.     

Preparation and characterization of TiO2 photoelectrode codoped with aluminum and boron and its application in dye-sensitized solar cell

Nanocrystalline titania films codoped with aluminum and boron were prepared by cathodic vacuum arc deposition. In the process, titanium alloy target was used under an O2/Ar atmosphere, and sensitization of films were carried out by natural dye-sensitized complex in anhydrous ethanol. The structure, surface morphology and UV-vis spectra of titania films codoped were measured by X-ray diffraction analysis, scanning electron microscopy and ultraviolet-visible spectrometer. Theas-deposited films are found to be amorphous. The films annealed were examinedto be of anatase structure with orientation along the (101) planes, the averagecrystal size is in the range between 41 and 45 nm. SEM results show that thereare some pores in the codoped titania films, the optical properties of the dye-sensitized films were also measured which reveals that the spectral responses of films shift to the visible region. Under simulated sunlight illumination, the overall energy conversion efficiency of dye-sensitized nanocrystalline solar cell is 0.9%.
