Well dispersed M@TiO2 (M = Ag, Pd, Au, Pt) nanocomposite particles with ultrafine noble metal nanoparticles can be synthesized on a large scale by a clean photochemical route without any additives being required. The nanocomposites show good catalytic performance for CO oxidation at low temperature and antibacterial effects at a low dosage.

Stabilization of the anatase phase of Ti1-xSnxO2 (x < 0.5) nanofibers is confirmed. Photoluminescence results demonstrate the tunable nature of the optical properties with the emission maximum shifting towards higher wavelength with increasing Sn concentration.

In situ scanning electron microscopy (SEM) tension and buckling tests on single ZnO nanowires (NWs) along the polar direction [0001] were conducted. The bending modulus increased more rapidly than the tensile modulus as the NW diameter decreased from 80 to 20 nm, which demonstrates that the elasticity size effects in ZnO NWs are mainly due to surface stiffening.
