1. MECHANISMS OF ENHANCED ACTIVITY OF MODEL TiO2/CARBON and TiO2/METAL NANOCOMPOSITE PHOTOCATALYSTS
Abstract : TiO2 is the most widely used photocatalyst for energy and environmental applications because of its outstanding physical and chemical properties. However, the quantum efficiency of TiO2 is greatly diminished by fast electron-hole pairs recombination and light absorption only in the UV region. READ MORE

5. Angle dependent light scattering of functional nanoparticle composites
Abstract : Varies functional nanoparticles play crucial roles in energy- and optical- related applications. The incorporation of functional nanoparticles into non-absorbing polymers to form optical absorption and scattering thin films have attracted considerable interest due to a successful selection of particles and matrices, synergistic effects of separation and fixation of particles, and controllable layer thicknesses and structures.
