9910429该奖项支持卡内基梅隆大学的Myung S.Jhon博士和韩国仁荷大学的Hyung J.Choi教授之间为期3年的合作研究项目。这项研究旨在通过研究聚合物磁盘润滑膜在固体表面铺展的基本机理，实现下一代硬盘驱动器(HDD)技术的突破。该项目的最终目标是了解润滑剂对摩擦学性能的作用，并建立HDD系统中润滑剂的分子设计标准。这项研究的重点将包括：进行SME(扫描显微椭圆仪)测量，同时系统地调整润滑剂-表面相互作用(润滑剂端基与各种高和低表面能表面的官能度)，执行流变学和表面能测量，并开发新的理论方法。该项目将与韩国仁荷大学的崔教授团队在美韩国际合作科学计划下进行，并将加强派的研究生的论文。该项目与美韩合作科学计划的目标相关，该计划旨在通过交流科学信息、想法、技能和技术以及通过在互利问题上的合作来提高美国和韩国科学家和工程师之间的合作水平。韩国的参与得到了韩国科学与工程基金会(KOSEF)的支持。

9910429JhonThis award supports a 3-year collaborative research project between Dr. Myung S. Jhon, Carnegie Mellon University, and Professor Hyung J. Choi, Inha University, Korea. The proposed research aims to obtain breakthroughs in next generation hard disk drive (HDD) technology by investigating the fundamental mechanism of spreading of thin polymeric disk lubricant films on solid surfaces. The ultimate goals of this project are to understand the role of lubricants on tribological performance and to establish molecular design criteria for lubricants in HDD systems. Highlights of the study will include:Performing SME (scanning microellipsometry) measurements while systematically tuning lubricant-surface interactions (lubricant end group functionality with various high- and low-surface energy surfaces),Performing rheology and surface energy measurements, andDeveloping novel theoretical methodologies.This project will be performed in conjunction with Professor Choi's group at Inha University, Korea under the U.S.-Korea International Cooperative Science Program and will enhance the dissertation of PI's graduate student. This project is relevant to the objectives of the U.S.-Korea Cooperative Science Program, which seeks to increase the level of cooperation between U.S. and Korean scientists and engineers through the exchange of scientific information, ideas, skills, and techniques and through collaboration on problems of mutual benefit. Korean participation is supported by the Korea Science and Engineering Foundation (KOSEF).
