Invited by Prof. Qibing Pei, Prof. Rujun Ma (馬儒軍) from Nankai University, visited our Institute on May 18, 2026. Prof. Ma is currently a Professor and Ph.D. supervisor at the School of Materials Science and Engineering of Nankai University.
Prof. Ma is a recipient of the China Youth Science and Technology Award, and has led many key projects of the National Key R&D Program of the Ministry of Science and Technology, etc. Prof. Ma’s main research interests are flexible active/passive solid-state cooling materials and devices and multifunctional flexible thermoelectric materials and devices. In recent years, he has published in Science (2), PNAS, Nature Communications (5), Joule (2), Chemical Society Reviews, Advanced Materials (5), and Nano Letters (10), etc. He has been authorized more than 20 patents in the United States, China, and South Korea, and has applied for 2 international patents.
Prof. Ma delivered a seminar entitled “Flexible solid state thermal management materials and devices with high efficiency”. The presentation focused on flexible, energy-saving and efficient solid-state thermal management systems, ranging from low energy consumption of the electrocaloric effect to zero energy consumption of the radiation effect thermal management system. He then discussed the self-sustainable wearable solid-state thermal management system with potential applications. Prof. Ma also introduced the zero-energy thermal management system with radiation effect, which not only solves the limitations of traditional radiation thermal management system in response to dynamic temperature changes but also realizes the zero-energy switching effect of the dual-mode of heat preservation and refrigeration. The energy-saving solid-state thermal management system highlights theoretical and technological support for the low energy consumption thermal management technology in future.
