양자물질초전도연구소에서 초청하신 워싱턴주립대 유충식 교수님께서 아래와 같이 특별강연을 하십니다.

학과 구성원 여러분의 많은 참석을 부탁드립니다.



일시: 10월 25일(화) 오전 11:00

장소: 7th Floor of Samsung Library

○ 연사: Prof. Choong-Shik Yoo (Washington State University)

○ Title: Crystallization of Water under Modulating Pressures 


○ Abstract:

Beauty of crystal facets and dendrites found in ice flakes and quenched metals has captured ones imagination as well as fundamental scientific interest in understanding the crystal growth mechanism associated with the roughening-faceting transition, surface instability, and fractal and dendritic pattern formation. The application of high pressure can exploit these fundamental phenomena of crystal growth, which can be readily compared with theoretical expectations. In this talk, I will describe the pressure-induced solidification of water under precisely controlled modulating pressures using dynamic-diamond anvil cell, exhibiting slow diffusion-controlled two-dimensional fractal growth, fast interfacial-controlled three-dimensional dendrite growth, shock crystal growth, and metastable crystal growth from super-compressed water.
