水界面主導許多自然現象，並對於先進觸媒和能源儲存裝置的發展非常重要，但人類對於其界面微觀結構的知識卻非常有限。本院物理所開發出一種動量解析式光學技術，可用於獲得有關水界面微觀結構和帶電狀態等微觀訊息。
Water interfaces are responsible for natural phenomena and of great importance in the development of advanced catalysts and energy storage devices. The interfacial processes are directly controlled by the interface-specific hydrogen-bonding network of water. However, knowledge on the microscopic structure and the interplay between ionic and molecular species therein is limited. Institute of Physics developed a nonlinear optical scheme with varying photon momenta for retrieving the vibrational spectra of the bonded interface water layer and the ion diffuse layer and, hence, microscopic structural and charging information about aqueous interfaces. This all-optic method offers microscopic probes of electrochemical and biological interfaces.
