PUBLIC ABSTRACTProposal Number: CBET-0742580Principal Investigator: Sinnott, SusanAffiliation: University of FloridaProposal Title: Atomic-scale Friction Research and Education Synergy Hub (AFRESH)Friction is a critical component of everyday life. Numerous applications require some friction to function effectively, such as car brakes and tires, while for other applications minimal friction is necessary to prevent the untimely wear of parts and the inefficient dissipation of energy, which is the case for the movement of pistons in car engines. It has been established that optimization of friction performance across systems first requires a thorough atomic-scale understanding, as all sliding surfaces ultimately interact via small surface areas. However, there is still much about atomic-scale friction, and the laws that govern it, that remain unknown.This engineering virtual organization will provide a vehicle for the atomic-scale friction community to come together to (i) share data, (ii) develop, disseminate and encourage the adoption of standards for the performance and analysis of both experiments and simulation, (iii) enhance and share computational and theoretical tools, and (iv) develop powerful teaching tools and related materials. It will also train graduate students in a multi-disciplinary environment, support forums for professional networking, build a diverse atomic-scale friction community, and facilitate outreach to other scientific communities and cyberinfrastructures.

公共摘要提案编号：CBET-0742580 首席研究员：Sinnott, Susan 所属机构：佛罗里达大学提案标题：原子尺度摩擦研究和教育协同中心 (AFRESH) 摩擦是日常生活的重要组成部分。 许多应用需要一定的摩擦才能有效发挥作用，例如汽车制动器和轮胎，而对于其他应用，需要最小的摩擦，以防止零件过早磨损和能量低效耗散，汽车发动机中活塞运动的情况就是如此。 已经确定，跨系统摩擦性能的优化首先需要彻底的原子级理解，因为所有滑动表面最终都通过小表面积相互作用。 然而，关于原子级摩擦以及控制它的规律，仍然有很多未知之处。这个工程虚拟组织将为原子级摩擦社区提供一个工具，让他们聚集在一起（i）共享数据，（ii） ）制定、传播和鼓励采用实验和模拟的性能和分析标准，（iii）增强和共享计算和理论工具，以及（iv）开发强大的教学工具和相关材料。 它还将在多学科环境中培训研究生，支持专业网络论坛，建立多样化的原子级摩擦社区，并促进与其他科学界和网络基础设施的联系。
