See the unseen with electron microscope!
에너지 생성, 전달 과정에서 일어나는 원자, 이온, 전자들의 움직임, 재분포를 최첨단 원자분해능전자현미경을 이용하여 실시간 관찰하여 에너지 생성 메커니즘을 이해하고, 성능 향상과 새로운 에너지 소재 설계에 기초자료를 제공합니다.
Using the state-of-the-art electron microscope, we trace the dynamic motions of atoms, ions and electron in real-time with picometer precision during the energy generation and transfer processes to reveal the fundamental mechanisms and provide a clue to the design of new energy materials.
