The presently disclosed invention provides for the fabrication of porous anodic alumina (PAA) films on a wide variety of substrates. The substrate comprises a wafer layer and may further include an adhesion layer deposited on the wafer layer. An anodic alumina template is formed on the substrate. When a rigid substrate such as Si is used, the resulting anodic alumina film is more tractable, easily grown on extensive areas in a uniform manner, and manipulated without danger of cracking. The substrate can be manipulated to obtain free-standing alumina templates of high optical quality and substantially flat surfaces. PAA films can also be grown this way on patterned and non-planar surfaces. Furthermore, under certain conditions, the resulting PAA is missing the barrier layer (partially or completely) and the bottom of the pores can be readily accessed electrically. The resultant film can be used as a template for forming an array of nanowires wherein the nanowires are deposited electrochemically into the pores of the template. By patterning the electrically conducting adhesion layer, pores in different areas of the template can be addressed independently, and can be filled electrochemically by different materials. Single-stage and multi-stage nanowire-based thermoelectric devices, consisting of both n-type and p-type nanowires, can be assembled on a silicon substrate by this method.

The present invention relates to a nano-sized photocatalytic sol and application thereof. The invention utilizes spherical nano-photocatalyst and non-spherical photocatalytic sol for coating a photocatalyst layer on a substrate. Because of the stereo, interlaced and composite structure between spherical photocatalyst and non-spherical photocatalyst, a hard and well adhesion coated layer of photocatalyst with good photocatalytic activity can be obtained without using binder.

The nanotube has a central region on the insulating layer above the gate electrode and first and second ends on the gate dielectric. A source is formed on the first end and spaced from the central region and gate electrode by a first peripheral region. A drain is formed on the second end and spaced from the central region and gate electrode by a second peripheral region. The first and second peripheral regions are doped with Cl2, Br2, K, Na, or a molecule of polyethylenimine using wet deposition or evaporation.

摘要:
A visible-light-activated photocatalyst powder and method for producing and modifying the same are provided. The visible-light-activated photocatalyst powder is produced by improving the process conditions or by modifying with platinum oxide. Further, the UV light-activated titanium dioxide is modified to be more visible light activated by loading platinum oxide on the surface of titanium dioxide. The methods enhance the conversion of sunlight irradiation to chemical energy. The air-born pollutants can be degraded by the treatment with the photocatalyst under UV or visible light irradiation.
