信息产业发展中的若干物理问题

为庆祝爱因斯坦创造奇迹100周年,2005年被确定为“世界物理年”．1905年爱因斯坦工作的论题涉及光电效应、布朗运动、特殊相对论和固态量子论．这些贡献推动诸多领域的进步并使每一个人从中受益。例如电视、激光、手机、计算机、互联网,乃至全球定位系统．此篇综述强调物理学在几乎所有工程技术领域的基础作用,内容包括巨磁电阻效应、自旋晶体管、纳米离子导体开关、单电子晶体管、碳纳米管、超导单光子探测器、SQUID器件和超导微波通信滤波器等。     

Applying Study of Hydrogen Storage Alloy

Hydrogen is an important source of energy.The natural resouces of hydrogen is plenty and it gives us lots of heat, and it is dean. One of difficulties of developing hydrogen sources of energy is hydrogen storage. Hydrogen storage tank is either dangous or a little of capacity. Liquid hydrogen occupys small space. Liquefaction temperature of hydrogen is -253℃ and need better heat insulation protection, the volumn and weight of heat insulation layer are equal to hydrogen storage tank. Hydrogen storage utillizing hydrogen storage material is a very safety, economical and effective method. Hydrogen storage material is either a medium of sofid hydrogen storage or is negative pole active material of Ni-H battery,and is the one of key technoloy of fuel and Ni-H battery, it is an important material of new sources of energy too.Nanotechnology is introduced Mg-matrix hydrogen storage alloy and is achieved progress gteatly,but hydrogen storage alloy need be mode further improvment on applying investigation.

Molecular insights into the novel aspects of diatom biology

Diatoms are unicellular photosynthetic eukaryotes that are thought to contribute as much as 25% of global primary productivity. In spite of their ecological importance in the worlds oceans, very little information is available at the molecular level about the novel aspects of their biology. Recent advances, such as the development of gene transfer protocols, are now allowing the genetic dissection of diatom biology. Notable examples are advances in understanding the genetic basis for the silica-based bioinorganic pattern formation of their cell walls and for elucidating key aspects of diatom ecophysiology. The potentiation of current research will allow an evaluation of the use of diatoms to construct submicrometre-scale silicon structures for the nanotechnology industry and will reveal the molecular secrets underlying their ecological success.
