양자물질초전도체창의연구소에서 워싱턴 주립대학의 유충식 교수님을 초청하여 10 25일에 특별 강연을 개최합니다.

유교수님은 고압력 연구에 명망이 있는 재미한인 과학자입니다. 많은 분이 참석하시면 좋을 것 같습니다.

 

Title: Crystallization of Water under Modulating Pressures

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

Time: 11:00 am on Oct. 25th, 2016

Place: Seminar Room on the 7th floor of Samsung Library

 

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.
