Dr. Zhang to Present at E-MRS Conference

Dr. Zhang will be giving a presentation at this spring’s E-MRS Virtual Conference on June 3rd. He will be presenting on the topic of advances in thermophotovoltaics: materials, devices and systems. His presentation will be focusing on the impact of photon entropy and chemical potential on thermophotovoltaic generators.

Zhang Honored with AIAA and ASME Awards

“Professor Zhuomin Zhang’s selection as the recipient of the 2021 AIAA Thermophysics Award is well-deserved recognition of his many contributions in the area of micro and nanoscale thermophysics. Professor Zhang is the consummate faculty member and researcher. He has and continues to provide strong leadership to the AIAA and other professional societies through his outstanding scholarship, mentorship of students and other faculty, and his active involvement and engagement in the heat transfer community.”

Four Endowed Professors Named

“I would like to congratulate each one of these faculty members on the outstanding achievements they have attained in their careers,” said Eugene C. Gwaltney, Jr. School Chair Samuel Graham. “These professors have distinguished themselves through research and leadership, and we are excited to invest in their futures. This would not be possible without the support of the Ring and Love families, and we are grateful for their ongoing commitments to the Woodruff School.”

About Us

Thermal radiation has played an important role in incandescent lamps, solar energy utilization, temperature measurements, materials processing, remote sensing for astronomy and space exploration, combustion and furnace design, food processing, cryogenic engineering, as well as numerous agricultural, health, and military applications.

The objective of our research group is to investigate the fundamental mechanisms of thermal radiation and to design and fabricate suitable micro/nanostructures for emerging technologies such as nanoelectronics, microscale thermophotovoltaic devices, nanothermal manufacturing, surface thermal metrology, and biotechnology. We investigate radiative energy conversion devices for power generation and refrigeration, as well as spectral absorptance of particles for solar energy harvesting.

Recent studies have shown that the near-field effects can realize emerging technologies, such as superlens, sub-wavelength light source, polariton-assisted biosensors, and energy conversion devices. Because of the important applications to energy transport and conversion, the study of engineered surfaces with desired thermal radiative characteristics using controlled micro/nanostructures has emerged as a new frontier in thermophysics and radiative transfer research.
