RESEARCH AREA
The
interdisciplinary chemistry research of our new research group focuses on
studies of chemical/biological processes on solid-state surfaces. This
includes:
(I)
Synthetic and mechanistic metal-organic chemistry.
(II)
Nanoscale assembly of molecular-derived thin films.
(III)
New strategies for thin film formation.
(IV)
Structural and optical properties of the thin film.
(V)
Reactivity, nuclease activity and molecular recognition by immobilized
supramolecular structures on various surfaces.
(VI)
Developing general methods for directing the formation of inorganic
clusters, solids, and molecules, particularly as a means of influencing the
physical properties and reactivity of such materials.
(VII)
Using variety of physio-chemical techniques, including air-free
synthesis, solvothermal synthesis, X-ray crystallography, optical spectroscopy,
electrochemistry, atomic force microscopy, x-ray photoelectron spectroscopy,
ellipsometry etc
