Abstract: A uniform composite nanofiber includes a tubular first nanofiber, and a second nanofiber formed inside or outside the first nanofiber. The first nanofiber is first formed within a plurality of nano-scale pores of a template placed on a current collector, and then the second nanofiber is formed on inner or outer surface of the first nanofiber, and the template is removed afterwards for obtaining the composite nanofiber.

Abstract: Methods of fabricating one-dimensional composite nanofiber on a template membrane with porous array by chemical or physical process are disclosed. The whole procedures are established under a base concept of “secondary template”. First of all, tubular first nanofibers are grown up in the pores of the template membrane. Next, by using the hollow first nanofibers as the secondary templates, second nanofibers are produced therein. Finally, the template membrane is removed to obtain composite nanofibers. Showing superior performance in weight energy density, current discharge efficiency and irreversible capacity, the composite nanofibers are applied to extensive scopes like thin-film battery, hydrogen storage, molecular sieving, biosensor and catalyst support in addition to applications in lithium batteries.

Abstract: A method for surface activation on the metallization of electronic devices is provided. It uses plasma-immersion ion implantation and electroless plating to implant the seeds onto the diffusion barrier layer as catalyst for the electroless Cu plating to accomplish the ULSI interconnect metallization. It achieves electroless Cu plating in the deep 100 nm scaled line-width ULSI interconnect metallization by the Pd plasma implantation catalytic treatment. The method can fill the 100 nm line-width vias and trenches for gaining high quality electroless plated metal interconnects, and substitute for the traditional wet activation by SnCl2 and PdCl2 solution. For the plasma implanted seeds and electroless copper techniques, good Cu step coverage and gap-filling capability are observed in the trench and via metallization process with high adhesive strength. After thermal treatment, no obvious interfacial diffusion induced electric failure is found in the interface of the Cu/(implanted Pd)/TaN/FSG assembly.

Abstract: A low-cost, simple method for manufacturing highly-ordered nanofibers is provided. The feature of the procedure is using a self-catalytic mechanism. First of all, a porous membrane template is used as a filter to spread metal nanoparticles, which have a self-catalytic characteristic, onto a current collector. After removing, the membrane template, the nanoparticles grow and become highly-ordered nanofibers by heat treatment in an oxygen atmosphere. The nanofibers show superior field emission effects and are therefore ideal field emission sources.

Abstract: The present invention provides a process for synthesizing one-dimensional nanosubstances. A membrane having channels serves as the host material for the synthesis. The anodic membrance is brought into contact with a microwave excited plasma of a precursor gas using an electron cyclotron resonance chemical vapor deposition (ECR-CVD) system. Parallel aligned nanosubstances can be synthesized in the channels of the membrane over a large area. Carbon nitride nanosubstances are synthesized successfully for the first time in the present invention.

Abstract: The present invention provides a molecular sieve composite membrane, which includes an anodic alumina membrane as a support and the uni-directionally oriented molecular sieve membrane grown in situ on the anodic alumina membrane. The close packing transitional metal containing aluminophosphate AFI molecular sieve crystals have successfully been grown on the anodic alumina. The molecular sieve phase bounded strongly and anchored into the anodic alumina membrane. Besides, the specific cylindrical channels of the anodic alumina membrane provides the template function to orient the growth of molecular sieves.

Abstract: .alpha.-Alumina fibers are produced by a sol-gel process using aluminum nitrate as a starting material. A reaction mixture including aluminum nitrate, water and aluminum particles is refluxed until the aluminum particles are completely dissolved to obtain an aluminum hydroxide sol. The aluminum hydroxide sol is then aged to increase the viscosity thereof, spun, dried and sintered to obtain .alpha.-alumina crystalline fibers.
