Relaxation dynamics of functionalized colloids on attractive substrates

C. S. Dias、Carlos Braga、N. A. M. Araújo 等 4 位作者2015-09-01arXiv (Cornell University)

Particle-based simulations are performed to study the post-relaxation dynamics of functionalized (patchy) colloids adsorbed on an attractive substrate. Kinetically arrested structures that depend on the number of adsorbed particles and the strength of the particle-particle and particle-substrate interactions are ident…

각섬석류를 활용한 하동지역 회장암체의 변성작용에 관한 연구

곽지영、Jin Beom Choi2015-09-01Journal of the Mineralogical Society of Korea

선캠브리아기의 지리산 편마암 복합체는 초기의 백립암상에서 후기의 각섬암상 또는 녹색편암상까지 후퇴변성작용을 받았으며, 편마암 복합체 내 관입한 하동 회장암체는 이 중 후기 변성작용의 영향을 받았다. 회장암체 내 주요 유색광물은 각섬석으로 이를 통해 변성조건 및 변성상에 관한 추정이 가능하다. 회장암체 내 각섬석은 개방니콜 하에서 주로 청녹색 내지 녹색을 나타내고, 반자형 내지타형의 형태를 보인다. 일부 갈색의 각섬석 주변부로 청록색으로 변하는 누대조직(zonal texture)이 존재하고, 사방휘석 내에는 각섬석으로 변하는 반응부가 존재해 후퇴변성 내지 변질 양상을…

Large Fermi Surface of Heavy Electrons at the Border of Mott Insulating State in NiS2

Sven Friedemann、Huan‐Cheng Chang、Monika Gamża 等 10 位作者2015-09-01Oxford University Research Archive (ORA) (University of Oxford)

One of the early triumphs of quantum physics is the explanation why some materials are metallic whereas others are insulating. While a treatment based on single electron states correctly predicts the character of most materials this approach can fail spectacularly, when the electrostatic repulsion between electrons ca…
