한국이 만든 ‘꿈의 신소재’ 세계 1위 찍다! 과학계 ‘발칵 뒤집은’ 초고성능 열전 신소재 / YTN 사이언스

Energy is essential for maintaining our smooth daily lives. However, only about 32% of our energy is used for daily activities, while the remaining 67% evaporates as heat and is ultimately wasted. To reduce energy waste, there is a scientist conducting research to recycle this wasted heat and convert it into electricity. Professor Jeong In of Seoul National University is that scientist. Professor Jeong In has developed a thermoelectric material that converts thermal energy into electrical energy using two substances: tin (Sn) and selenium (Se). Thermoelectric efficiency is higher when thermoelectric materials possess low thermal conductivity and high electrical conductivity. Since tin oxide increases thermal conductivity, Professor Jeong In spent years researching ways to eliminate tin oxide to address this issue. Finally, by developing a method to remove tin oxide, he created a thermoelectric material with the world's highest efficiency, capable of converting thermal energy into electrical energy with a conversion rate exceeding 20%. Professor Jeong In, who has opened a new horizon for ultra-high-performance thermoelectric technology. Based on his advisor's teaching that one must conduct original research that others do not pursue, rather than merely applying the results of other researchers, he has created his own unique world. Furthermore, his research motto is that the fundamentals are paramount for achieving originality. Rather than relying on existing data, he reportedly conducts experiments and observations directly using the elements of the periodic table... Let's listen to the story of Professor Jeong In, who creates substances that do not exist on Earth through scientific originality. 👉This video is a segment from a broadcast aired in April 2023.
