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.

该项目旨在改进纳米级粘附力和摩擦力的测量。纳米晶须和衬底之间的粘附和摩擦的理解是至关重要的开发下一代纳米器件。然而，目前用于测量纳米级粘附力和摩擦力的方法是不准确的，并且可能产生相互矛盾的结果，这是由于掌握复杂的测量技术的极端挑战以及对其潜在机制缺乏了解。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。这项研究的成功结果不仅解决了纳米晶须应用中的一个长期存在的问题，而且还产生了新的纳米表面科学。
