A highly ordered and crystallized titania (TiO(2)) nanotube array is fabricated by a low-voltage anodization plus a post-embedding calcination process. Polyoxophosphotungstate-titania (POPTA-TiO(2)) composite catalyst is synthesized by embedding POPTA in TiO(2) tubule channels to improve the photoelectrochemical properties. The morphological characteristics(More)
The first to fourth generation (G1-G4) of sectorial poly(amido amine) (PAMAM) dendrimers with ethanolamine core and amino terminals are synthesized by a divergent route. Blue fluorescence emission from these dendrimers is observed. It is found that there is a remarkable difference in the fluorescence behavior for these different generations of dendrimers.(More)
The glucose oxidase (GOD) modified polypyrrole/titania nanotube enzyme electrode is fabricated for electrochemical biosensing application. The titania nanotube array is grown directly on a titanium substrate through an anodic oxidation process. A thin film of polypyrrole is coated onto titania nanotube array to form polypyrrole/titania nanotube hybrid(More)
In this paper, dimer and trimer assemblies were prepared through covalent coupling of the monomer, i.e., carboxyl monofuntional gold nanoparticles using Tris(2-aminoethyl)amine (Tren) as a bridging ligand. TEM examination showed that the dimer structures could be obtained with an increased yield using Tren instead of ethylenediamine (EDA) as a bridging(More)
