Novel submicron scale composites with hollow hexagonal cylinder structures were prepared by hydrolysis of tetraethyl orthosilicate in a micelle solution composed of polyoxyethylene (n = 15) cetyl ether/cyclohexane/water containing Co-N 2H 4 compound nanoparticles.

Pt metal catalyst covered with silica layers oxidized methane preferentially in the competitive oxidation of methane and isobutane with gaseous oxygen. Selectivity in the competitive oxidation of mixed hydrocarbons over the catalyst was controlled by the diffusion rates of the reactants in the silica layers which wrapped Pt metal particles.

Monodispersed polymer/polydiacetylene composite particles were synthesized by soap-free seeded emulsion polymerization of styrene and methyl methacrylate; the products were characterized by XRD, SEM, TEM, UV-visible spectroscopy, and single particle scattering spectroscopy. In the synthesis process, polydiacetylene nanocrystals were found to act as inhibitor, and consequently a relatively low concentration was necessary. Different monomers lead to the differences in reaction condition and particle morphology; the PMMA composite particles were simpler in preparation than polystyrene particles, but the latter have better spherical morphology. The composite particles were composed of polymer shells and polydiacetylene cores, which kept their crystal structure and optical properties. A high percentage of cored particles could be achieved with optimized reaction conditions where the amount of seed was sufficient and the oily oligomer by-product was suppressed.

This paper presents single particle fluorescence spectroscopy of perylene nanocrystals coupled with AFM observation of their topographic shapes. The fluorescence spectra of individual nanocrystals confirmed clearly and precisely a blue-shift in the excimer emission maximum on the reduction of their volume. The result can be explained in terms of "lattice softening", which makes intermolecular interaction weaker and modified the energy level of the excimer state in nanocrystal. © 2005 Materials Research Society.

A general strategy for preparing a stable assembly of nanoparticles was demonstrated. It was emphasized that almost all the titanium dioxide-wrapped particles could be dispersed independently using this technique and their aggregation was not observed. As such, this nanoparticle assembly and wrapping technology can be widely applied to other metal and semiconductor particles as well as to nanosized materials.

A study is conducted to demonstrate how layered nanocomposite of close-packed gold nanoparticles and TiO2 gel layers. The study demonstrates the preparation of alternate layers of ultrathin TiO2 films and modified gold nanoparticles. The modified gold nanoparticle possesses surface hydroxyl groups, and they behave as an active component in the surface sol-gel process. Nanocomposites obtained from these components will be composed of high concentrations of nanoparticles in metal oxide thin films. Gold nanoparticles are prepared by reduction of HAuCl4 by NaBH4 in methanol/acetic acid in the presence of (SC11OH)2. Each particle had a spherical shape of a uniform size.
