■ Kwon Oh-hoon/Professor of Chemistry at UNIST The 54th protagonist! Dr. Kwon Oh-hoon! Dr. Kwon Oh-hoon has developed the world's only ultra-fast 4D electron microscope, and is discovering the structure and phenomena of substances that were not previously seen. The reason why the electron microscope developed by Dr. Kwon is special is because it can capture the moment when substances react and combine, and by stitching these photos together, it is possible to observe the changes and movements of substances as if they were a 'video'. This was possible because the limitations of existing electron microscopes were overcome by adding a 'femtosecond laser'. The world of substances that occur within 'femtoseconds (1/1000 trillionth of a second)' is unfolding before our eyes. He is studying the structure and phenomena of various substances that react to light with the microscope he developed. He succeeded in 'directly elucidating' the mechanism of how 'gold nanoparticles' convert light energy into heat energy, and also captured the wrinkle formation process of the 2D material 'black phosphorus' for the first time. Dr. Kwon Oh-hoon is receiving worldwide attention for his extraordinary technological prowess. But there is a very special person behind the glory of today? Dr. Kwon, who says that the advancement of science begins with the discovery and observation of new phenomena. We will learn about the research secrets of Dr. Kwon, who broadened the 'vision of science' with infinite positivity and patience and presented 'new eyes' to mankind. We will look into the research and lives of scientists who are leading science in Korea and cheer them on (Bravo K-SCIENTIST) #CellTherapy #Semiconductor #Display #EVCell #ElectronMicroscope [YTN Science Original Article] https://science.ytn.co.kr/program/pro...
