Chia-Liang Cheng, Professor of Physics at National Dong Hwa University, Taiwan
will be giving a joint MSI/Physicsl Chemistry talk titled:

"Nanodiamond: Spectroscopy and Biological Applications"

Research Interests:

Spectroscopic studies of nanomaterials. Methods used include Infrared, Raman spectroscopy, confocal laser fluorescence microscope, surface characterization methods such as SEM, TEM, etc; the nanomaterials studied include Diamond-like carbon, single crystal diamonds, nanodiamonds, carbon nanotubes, visible-light activated TiO2 nanoparticles, CuO nano wires.

1. Spectroscopic studies of single crystal diamonds, diamond-like carbons, nanodiamonds, and thin diamond films using IR and Raman spectroscopy to characterize the materials.
2. Study visible-light activated TiO2 nanoparticles: To characterize the visible-light activated TiO2 nanoparticles; to develop theory of
carbon-containing visible-light activated TiO2 for phtocatalytic applications.
3. Develop nanodiamond-protein complexes for bio applications using nanodiamond's spectroscopic signal (fluorescence or Raman signals) as a marker for bio labeling.
4. Spectroscopic study of a single CuO nanowire includes; the deposition, the characterizing and its growth mechanism.
