We prepared the ordered porous alumina membrane by a two-step anodization method in oxalic or sulfuric acids, which is a self-ordered hexagonal array of cells with an adjustable pore diameter of 20-150nm and a different pore structures (i.e. Y-branched, dendriform, toothed and torous ones). Furthermore, the template-electrodeposition, vapor-catalytic growth, and controlled chemical etching were developed for well-aligned carbon nanotubes and oxide nanopillars with adjustable diameter, Al2O3-AlN one-dimensional heterojunction, Y-junction and dendriform metal nanowires, as well as Y-junction, and torous carbon nanotubes. The resultant one-dimensional junctions were characterized by XRD, SEM, TEM,HRTEM, and STM, and the field emission of the well-aligned carbon nanotubes and the luminescence of ZnO nanopillar array have also been mearsured.

In Wistar rats, latent period of a-wave in scotopic rod response after 1-week transplantation was shorten (P.05); and latent period of a-wave in scotopic rod response after 2-week transplantation was prolonged (P.05); while latent period of b-wave in scotopic maximum response after 1-week transplantation was shorten (P.05). In RCS rats, amplitude of a-wave in scotopic rod response and photopic response after 4-week transplantation was increased (PO.05); while latent period of a-wave in scotopic rod response after 4-week transplantation was shorten (PO.05).Conclusion 1. At the age of 3 months, photoreceptors of the RCS rat degenerated completely, which leaded to the reduction of amplitudes of a-wave and b-wave.

By low temperature (145K) deposition method, we prepared such flat Pb films on the Si (111) substrate over a wide thickness range (from 10ML to 32ML). The unique growth behaviors were investigated by RHEED, STM and ARPES. A critical thickness of 10ML is established, at which the atomically flat Pb films become stable at room temperature. Between 10ML and 20ML, the growth exhibits a quasi bi-layer growth mode. Above 21ML, a layer-by-layer growth mode was observed.
采用低温生长的方法(衬底温度145K),通过对生长条件的优化,我们在Si(111)衬底上制备出了具有原子级平整度的Pb 薄膜,用STM 和ARPES确定了其特殊的生长模式:室温下成膜的临界厚度是10ML,随后是一种双层生长模式,覆盖度高于21ML 时,薄膜生长基本上是层状生长的模式。

Results show that when the thickness is less than 0.7 nm, Si3N4, normally amorphous in deposition state, could form a NaCl-type pseduocrystal structure due to the template effect of TiN crystal layer. Crystallized Si3N4 layers and TiN template layers grow coherently into columnar crystals with (111) preferred orientation. Correspondingly, the hardness of the films was enhanced to a maxim value of 38.5 GPa, showing a superhardness effect.
结果表明,在TiN调制层晶体结构的模板作用下,溅射态以非晶存在的Si3N4层在其厚度小于0.7 nm时被强制晶化为NaCl结构的赝晶体,多层膜形成共格外延生长的(111)择优取向超晶格柱状晶,并相应产生硬度显著升高的超硬效应,最高硬度达到38.5 GPa。
