Developing innovative methodologies to understand nano-adhesion/friction

该项目旨在改进纳米级粘附和摩擦的测量。了解纳米晶须与衬底之间的粘附和摩擦对于开发下一代纳米器件至关重要。然而，由于掌握复杂的测量技术和缺乏对其潜在机制的理解，目前测量纳米尺度粘附和摩擦的方法是不准确的，并且可能产生相互矛盾的结果。该项目旨在开发创新的“推剥”和“推滑”方法，以准确测量这些特性，并进一步了解它们的基本起源。该研究的成功成果不仅解决了纳米晶须应用中的一个长期难题，而且还催生了新的纳米表面科学。

The project seeks to improve the measurement of nanoscale adhesion and friction. The understanding of adhesion and friction between a nanowhisker and a substrate is crucial for developing next-generation nanodevices. However, the current methods for measuring nanoscale adhesion and friction are inaccurate and can produce contradictory results, due to the extreme challenges in mastering sophisticated measuring techniques and the lack of understanding of their underlying mechanisms. This project aims to develop innovative ‘push-peel’ and ‘push-slide’ methods to accurately measure those properties and to further understand their fundamental origins. Successful outcomes from this study would not only solve a long-standing problem in the application of nanowhiskers, but also generate new nanosurface science.
