Research Interests

Membrane Technology , Chemical and Chemical Process Safety , Chitosan Application
Membrane Technology
The focus of the research is on the synthesis of new membranes for water and wastewater treatment , ethanol dehydration , gas separation and fuel cell membrane. The research fields are concerned on reverse osmosis , nanofiltration, ultrafiltration , pervaporation, gas separation membrane and ion exchange membrane.

Chemical and Chemical Process Safety
The analysis of chemical reactivity hazards and the prevention and mitigation of uncontrolled chemical reactions are interested in. The researches are focused on the physical hazard evaluation of chemicals , study on runaway reactions , chemical instability , thermal sensitivity , material incompatibility , and uncontrolled reaction consequences.

Chitosan Application
Chitosan in the form of membrane as well as flake form are used for water and wastewater treatment , pervaporation, gas separation membrane and fuel cell membrane.
