In this paper, a surface plasmon resonance （SPR） sensor chip for detection of bovine serum album （BSA） was prepared by electropolymerization of 3-aminophenylboronic acid （3-APBA） based on molecularly imprinted polymer （MIP） technique. The surface morphology of MIP and non-imprinted （NIP） films were characterized by scanning electroscopy （SEM）. SEM images exhibited nanoscale cavities formed on the MIP films surface homogeneously due to the removal of BSA templates. The effects of pH, ion strength of rebinding BSA, the specific binding and selective recognition were studied for MIP films. Results indicated that the BSA-imprinted films exhibited a good adsorption of template protein （0.02-0.8 mg/mL） in 0.05 mol/L sodium phosphate buffer at pH 5.0 with the limit of detection （LOD） of 0.02 mg/mL.

为了探究锐钛矿相TiO_(2)(a-TiO_(2))对柴油中典型氮化物(吡啶、苯胺、喹啉)及非氮化物的吸附行为和选择性,利用模拟计算方法研究了吡啶、苯胺、喹啉及非氮化物在a-TiO_(2)(101)晶面吸附过程中的吸附构型、吸附能、Mulliken电荷、电荷密度、差分电荷密度和态密度等。结果表明:吡啶、苯胺、喹啉吸附于a-TiO_(2)(101)晶面的吸附能分别为-188.59,-100.99,-201.63 kJ mol,3种氮化物均能稳定吸附于a-TiO_(2)(101)晶面,其吸附稳定性由大到小的顺序为喹啉>吡啶>苯胺;在吸附过程中,氮化物将自身一定量的电荷转移到a-TiO_(2)(101)晶面,形成氮化物→a-TiO_(2)(101)晶面的电荷转移通道;吡啶和喹啉在a-TiO_(2)(101)晶面吸附时形成N—Ti化学键,苯胺的氨基H和a-TiO_(2)(101)晶面的O形成氢键。芳烃、烷烃、环烷烃等非氮化物在a-TiO_(2)(101)晶面的吸附强度相近,均弱于氮化物。a-TiO_(2)对氮化物有较好的吸附脱除效果,能选择性去除柴油中的碱性氮化物。

Using the direct method for a coupled KdV system, six types of the similarity reductions are obtained. The group explanation of the results is also given. It is pointed out that, in order to find all the results by nonclassical Lie approach, two additional condition equations should be satisfied at the same time together with two original equations.

The dynamics of quantum entanglement described by the yon Neumann entropy is studied for the localized states of Fermi-resonance coupling vibrations in molecule CS2, where the interacting energy between the stretching and the bending modes is considered to establish a connection between entanglement and energy. It is shown that entanglement reveals dominant anti-correlation with the interacting energy for the stretch-localized state, while that exhibits dominantly positive correlation for the bend-localized state. The entanglement and the energy for the dislocalized states are discussed as well. Those are useful for molecular quantum computing and quantum information in high dimensional states.

Developing renewable energy is now becom- ing a hot topic as it is important in dealing with climate change issue and energy supply issue. With the growing demand of energy, it has become urgent to develop the effective policies and measures that would enable people to maintain the living standards. Among all the measures, price is an essential one. In order to evaluate the costs and prices of the electricity from renewable energy sources （RES-E） and their effects to the market, this paper firstly focus on the extra costs of the RES-E by breaking it into four parts, including investment, construction, connection and operation. Then, the policy choices made in some typical industrialized countries are examined to find answers to the problems RES-E can raise. Finally, the choices made in China are examined in comparison to industrialized countries so as to determine how the current situation could be improved.
