摘要:Quantum behaviors of protons in terms of tunneling and zero-point motion have significant effects on the macroscopic properties, structure, and dynamics of water even at room temperature or higher. In spite of tremendous theoretical and experimental efforts, accurate and quantitative description of the nuclear quantum effects (NQEs) is still challenging. In this talk, I will highlight the recent advances of scanning tunneling microscopy (STM) and qPlus sensor based non-contact atomic force microscopy (nc-AFM), which allows the access to the quantum degree of freedom of protons both in real and energy space. Then I will discuss how the STM/AFM are used to directly visualize the concerted quantum tunneling of protons within the water clusters and quantify the impact of zero-point motion on the strength of a single hydrogen bond (H bond) at a water/solid interface. At last, I will highlight the crucial role of NQEs in surface chemistry and material science.
