Cheng C.-L., Chen C.C., Chen T.T., Chen Y.F., Cheng C.-L., Lin H-Y, Chen C.C., Chen T.T., Chen Y.F., Cheng C.-L., Chen C.C., Chen T.T., Chen Y.F., Cheng C.-L., National Taiwan University, TW

A novel approach based on vapor-phase transport technique using Au-coated plant cell walls with metallic ions as the catalyst has been developed to synthesize ZnO nanostructures. It is shown that plant cell walls can serve [...]

Raman and Photoluminescence Spectroscopy Investigations of ZnO Nanostructures

Chen B., Chen C., Ng H.T., Chen B., Chen C., NASA Ames Research Center, US

One-dimensional inorganic nanowires are expected to play important roles in optoelectronic device applications. The unique properties such as grain boundary and high surface area of these nanostructures are clearly different from the corresponding bulk material. [...]

ZnO Nanoparticles Beaded Multiwalled Carbon Nanotubes

Zhu Y., Elim H.I., Foo Y.L., Triparthy S., Quek W.T., Ji W., Thong J., Sow C.H., National University of Singapore, SG

In this work, we report a hybrid system of ZnO nanoparticles on MWNT scaffolds synthesized via a very simple and straightforward process. This involved the coating of pure Zn on as-grown aligned MWNT films, followed [...]

Physicochemical Characterization of Nanosize Zinc Oxide and Titanium Dioxide used as UVR Sunscreen Agents in Cosmetic Formulations

Morfesis A., Fairhurst D., Malvern Instruments, Inc., US

The physical (particulate) sunscreen agents, ZnO and TiO2, are increasingly used to provide UV protection in a wide variety of cosmetic and personal care products. The particle size distribution (PSD) of the ZnO and TiO2 [...]
