The project aims for the thorough investigation of the scale effect and the associated energy dissipation in nanoscale mechanical resonator operated in air. An integrated research program is proposed which combines unique experimental approaches with advanced research tools and appropriate theoretical analyses. Nanoscale beam resonators integrating individual nanostructures will be developed. An all-electronics approach will be realized for the driving and sensing of the resonance. The experimental study will be further corroborated with theoretical analysis in order to gradually develop a comprehensive and solid understanding of scale effect and energy dissipation in such a nanosystem. The study of nanoscale mechanical resonator systems has previously mostly limited to vacuum environment or cryogenic temperature. The proposed study, besides providing fundamental knowledge on an interesting scientific subject, namely the scale effect in mechanical resonance system at the nanoscale, can ultimately lead to the development of novel nanoscale devices for high sensitivity mass and biomolecular sensing in ambient environment. A multifaceted educational program coupled with the proposed research provides also a perfect learning and training opportunity for the active participation and effective education of students and the public, which facilitates the wide dissemination and transfer of scientific knowledge and ultimately benefits the society.

该项目旨在彻底研究空气中运行的纳米级机械谐振器的尺度效应和相关能量耗散。 提出了一个综合研究计划，将独特的实验方法与先进的研究工具和适当的理论分析相结合。 将开发集成单个纳米结构的纳米级光束谐振器。 将实现全电子方法来驱动和传感谐振。 实验研究将进一步与理论分析相证实，以逐步对这种纳米系统中的尺度效应和能量耗散产生全面而扎实的理解。 纳米级机械谐振器系统的研究以前大多局限于真空环境或低温。 所提出的研究除了提供一个有趣的科学主题（即纳米尺度机械共振系统的尺度效应）的基础知识外，最终还可导致开发用于环境环境中高灵敏度质量和生物分子传感的新型纳米尺度设备。 多方面的教育计划与拟议的研究相结合，还为学生和公众的积极参与和有效教育提供了完美的学习和培训机会，从而促进科学知识的广泛传播和转移，最终造福社会。
