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Propopals编号：CBET-0742580原理研究者：Sinnott，Susanaffiliation：佛罗里达大学佛罗里达大学的摩擦研究与教育协同枢纽（Afresh）摩擦是日常生活的关键组成部分。 许多应用需要一些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，对于防止零件的磨损和能量效率低下的能量耗散是必要的最小摩擦，这是汽车发动机中活塞的这种情况。 已经确定，在整个系统中优化摩擦性能首先需要彻底的原子尺度理解，因为所有滑动表面最终都通过小型表面区域相互作用。 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 材料。 它还将在多学科环境中培训研究生，支持专业网络的支持论坛，建立多样化的原子尺度摩擦界，并促进与其他科学社区和网络基础设施的宣传。
