The energy crisis and environmental pollution have stimulated the interests of scientists and researchers worldwide in the exploration of new renewable energy sources and development of environmentally friendly energy conversion technologies. Our group is interested in modern electrochemical technologies coupled with external parameters, such as heat and light, for energy conversion and recycling; these combined approaches can open new horizons and provide synergistic effects. The current research focuses on the development of new electrochemical technology for (1) low-grade heat-to-electricity conversion, (2) solar and indoor light harvesting, and (3) nanomaterial fabrication. Our work is interdisciplinary and combines mechanical engineering, chemical engineering, electrical engineering, and materials science.
