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
