Research Topic

Electrochemical Engineering
The electrochemical technology has been applied extensively to many fields such as plating, surface finishing, corrosion, battery, sensors, wastewater treatment, electronic industry, etc. Our research is on applying the fundamental principles of electrochemical engineering and science to various electrochemical systems. In an electrochemical system it involves the electrode kinetics on the electrode surface, current flow in solution, fluid flow and mass transport of relevant species to surface, and chemical reactions if they happen, In our research the mathematical model of the electrochemical system is set up and compared with the experimental results. Recent studies include the electrochemical drug delivery and the simulation of lithium batteries.

 

Wastewater and Soil Treatments
The electrochemical techniques, such as electrolysis, electroflotation and electrocoagulation have been found to be useful for wastewater treatments. The metal recovery from dilute solutions by high specific surface-area electrodes, such as packed bed electrodes and fluidized bed electrodes, and the electrolytic destruction of toxic chemicals such as cynides have been studied in our laboratory. Currently the electrokinetic processing in porous media is being investigated, and it has potential application for the remediation of contaminated soils.

 

Spinning Processes in Electronic Materials Processing
The operation of spinning units, such as spin coating and spin-on-glass is quite important in semiconductor processing and other related fields. The study of the spin coating in the lithographic process, which involves many chemical engineering principles, is currently under way.
