用化学腐蚀制备多孔硅太阳电池减反射膜的研究

采用HF HNO3溶液化学腐蚀 ,在硅片上制备减反射效果优良的多孔硅太阳电池减反射膜 ,借助原子力显微镜 (AFM)和X光电子谱 (XPS)对其表面形貌和成分进行观察 ,发现该膜与电化学阳极腐蚀得到的多孔硅具有相似性 ,其主要成分为非化学配比的硅的氧化物SiOx(X <2 )。采用带积分球的光度分光计 ,测得形成多孔硅减反射膜后 ,硅片表面反射率大大下降 ,,在波长 330～ 80 0nm范围反射率只有 1 5～ 2 9%。研究指出这种强减反射作用 ,与多孔硅具有合适的折射率及其多孔特性的光陷阱作用有关     

共晶碳化物团球化对铸铁激光熔敷层抗裂性的影响

为提高铸铁表面大面积激光熔敷层抗裂性问题，通过冶金因元素控制熔敷层组织形态在熔敷材料中加入碱金属元素钾，研究了在激光快速加热条件下钾对铸铁激光熔敷层组织团球化的影响，进而分析了该球状组织对熔敷层抗裂性的影响，结果表明随熔敷金属内钾含量增多熔敷层内共晶碳化物组织呈球状及孤岛状，这种组织明显提高了熔敷层抗裂性，此外大量的渗碳体组织确保了熔敷层具有较高的耐磨性；获得了无裂纹的大面积搭接熔敷层，其对应合金系统为Fe-C-Si-Ni-K。     

Corrosion behaviour of low-Si alloyed steels in neutral reducing conditions at 90 °C

Electrochemical investigations on low-Si alloyed steels with Si content ranging from 0.25 to 3.2 wt.% were carried out in a 0.1 M NaCl borate-buffered solution (pH 8.4) in reducing conditions at 90 °C. Silicon as an alloying element was proved to degrade at first the steel ability to passivate. For longer immersion times, protective effects developed more efficiently on the steel containing 3.2 wt.% silicon. Passive layers electrochemically formed in the transpassive domain on the steel containing 3.2% Si were shown to be significantly different from those grown at rest potential.

Evaluation of Digitally Encoded Layer‐by‐layer Coated Microparticles as Cell Carriers

To obtain more biologically relevant data there is a growing interest in the use of living cells for assaying the biological activity of unknown chemical compounds. Density ‘multiplex’ cell‐based assays, where different cell types are mixed in one well and simultaneously investigated upon exposure to a certain compound are beginning to emerge. To be able to identify the cells they should be attached to microscopic carriers that are encoded. This paper investigates how digitally encoded microparticles can be loaded with cells while keeping the digital code in the microcarriers readable. It turns out that coating the surface of the encoded microcarriers with polyelectrolytes using the layer‐by‐layer (LbL) approach provides the microcarriers with a ‘highly functional’ surface. The polyelectrolyte layer allows the growth of the cells, allows the orientation of the cell loaded microcarriers in a magnetic field, and does not hamper the reading of the code. It has further been shown that the cells growing on the polyelectrolyte layer can become transduced by adenoviral particles hosted by the polyelectrolyte layer. It is concluded that the digitally encoded microparticles are promising materials for use in biomedical and pharmaceutical in‐vitro research where cells are used as tools.     

苏里格低渗强非均质性气田开发技术对策探讨

鄂尔多斯盆地苏里格气田储集层具有低渗、强非均质性、中强压敏的特点，气井产能低，稳产期短。根据单井模拟及生产动态分析，气井低产量生产可以降低压敏效应的影响，加强气井低产量生产阶段的管理，有利于合理利用地层能量，提高井控外围低渗区储量动用程度；分层压裂、多层合采可以在纵向上充分动用气井控制储量，增加气井最终累计产气量和稳产时间；地质研究与地震相结合，是提高储集层预测精度和钻井成功率的技术关键；降低成本，争取优惠政策也是提高经济效益的有效途径。
