Current Research Interests
Research in Professor Kang"s group focuses on the study of chemical problems on various types of surfaces and interfaces by using modern spectroscopic methods. Part of our research effort involves the exploration of chemistry of ice surfaces. Ice surfaces offer a unique reaction environment much different from that in liquid water, but current knowledge of reactions on ice is very limited. We aim at understanding fundamental chemical properties of ice surfaces, and seek for relevant interpretation for environmentally important processes such as chemistry in the polar region, in the stratosphere, and in interstellar space. Another project involves the local probe investigation of solid-liquid interfaces. A miniaturized potential probe is developed to measure the electrical potential of a solid-liquid interface with nanometer spatial resolution. Current research endeavor with this new local probe includes exploring the electrical double layer at an electrode-electrolyte interface and the electron transfer process across a charged interface. The above-mentioned approaches are applicable to a host of other research fields such as nanotechnology, environmental chemistry, physics, and biology. The work involves largely experimental investigation, but occasionally computer simulations as a supplementary method.
