Nanotribology and Nanorheometry: A Fundamental Study of the Dynamic Interactions of Particles and Surfaces at the Molecular Level

摩擦和变形是由微观颗粒和表面的相互运动和相互作用产生的。本研究旨在通过将数学分析和数值计算与动态力测量、表面修饰以及纳米和分子长度尺度的表面表征相结合，来发展针对这些非平衡现象的新的理论和测量技术。这些见解和数据将在设计节能和耐磨的低摩擦表面、开发软聚合物和生物材料的机械和结构特性的纳米探头以及在技术先进的应用中控制附着力和颗粒聚集的高性能涂层方面至关重要。

Friction and deformation occur from the mutual motion and interaction of microscopic particles and surfaces. This research aims to develop new theories and measurement techniques for these non-equilibrium phenomena by combining mathematical analysis and numerical computations with dynamic force measurement, surface modification, and surface characterisation on nanometre and molecular length scales. These insights and data will be critically important in designing low-friction surfaces that save energy and wear, in developing nanoscopic probes for the mechanical and structural properties of soft polymeric and bio-materials, and in making high performance coatings that control adhesion and particle aggregation in technologically advanced applications.
