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.

At a recent show he unveiled four new pets: a portable lightning machine that spits 9-foot bolts of crackling blue lightning at nearby machines; a 120-decibel whistle driven by a jet engine; a military rail gun that uses magnetic propulsion to fire a burning comet of molten iron at 200 miles per hour, which upon impact explodes into a fine drizzle of burning droplets; and an advanced tele-presence cannon, a human/machine symbiont that lets a goggled operator aim the gun by turning his head to gaze at the target. It fires beer cans stuffed with concrete and dynamite detonators.

Mr Thompson's approach deals summarily with geology, Herdwick sheep, mining and the Celts and Norse-Irish who bequeathed many of the place names to the eight valleys that, according to Wordsworth's description, radiate "from the nave of a wheel", a nub of rock formed by volcanoes as powerful as Vesuvius.

The prepared PU was an elastic solid,which could dissolved in ethanol,and it exhibited strong deep purple fluorescence at the peak of 365 nm along with a shoulder at 386 nm as a thin film. Obviously,the prepared PU also was a kind of uncommon ultraviolet-emitting polymer materials.2.A novel water-soluble rod-coil block copolymer was designed and prepared successfully via the facile isocyanic acid polycondensation method using polyfluorene as rod segment and polyethylene glycol as coil segment in the main chain for the first time.
所制备的聚氨酯是一种弹性固体,可以溶解在乙醇中,同时又显示出具有半导体性质的荧光性能——最大荧光发射峰在365 nm并且在386 nm处有一个小的侧肩峰,可见它又是一种非常难得的紫外发光聚合物材料。2、首次采用了简单的异氰酸酯反应,成功地将聚芴作为刚性链段和聚乙二醇作为柔性链段,以嵌段方式连结到聚合物分子主链上,从而形成了一种新型的具有刚性链—柔性链结构的嵌段共聚物。

XRD showed hexagonal wurtzite structure. Room-temperature PL spectra of perfectly overcoated CdSe/ZnS only showed a narrow band edge emission. Emission peak was great red-shifted relative to absorption and the shift increases as the size decreases. The size-dependence of shift could be explained very well in terms of excition fine-structure model and stress at interface owing to lattice mismatch contributes to the shift between CdSe and CdSe/ZnS with the same size.
结果显示表面修饰完善的样品的荧光光谱只有一个窄而强的带边发射;所有样品的荧光峰相对于1S-1S吸收峰有较大的红移,并且移动量随尺寸的减小而增加,利用激子的精细结构模型很好地解释了红移量和尺寸的关系;核/壳结构的样品的吸收峰和荧光峰相对于同尺寸的单量子点也有红移现象,这是由于CdSe和ZnS的晶格失配在界面上产生压力造成的。
