In this award, funded by the Experimental Physical Chemistry Program of the Division of Chemistry, Professor Anders Nilsson of Stanford University, together with his graduate student researchers, will investigate the nature of the hydrogen bond network in liquid water. The main experimental techniques to be used include x-ray absorption spectroscopy, x-ray raman scattering measurements, small-angle x-ray scattering and x-ray diffraction measurements. These experiments will be carried out at the SSRL synchrotron radiation facility as well as with equipment in the Nilsson laboratory. The work will be augmented with a theoretical collaboration with a Swedish computational chemistry group.Water is the reaction medium for the most important environmental and life processes. Many of the unique chemical and physical properties of water are due to its propensity to hydrogen-bond with itself and other species. The work of Prof. Nilsson and his group is aimed at developing a better description of the hydrogen bond network in liquid water. The students working in the Nilsson laboratory will have the opportunity to work in one of the premier light sources in the country, and will further benefit from an international collaboration. Besides being intimately involved in the research work, Prof. Nilsson is an outstanding ambassador for science, participating in a number of public outreach activities at Stanford as well as at the Exploratorium in San Francisco.

斯坦福大学的Anders Nilsson教授将与他的研究生研究人员一起，研究液态水中氢键网络的性质。该奖项由化学系实验物理化学项目资助。主要实验技术包括x射线吸收光谱、x射线拉曼散射测量、x射线小角散射和x射线衍射测量。这些实验将在SSRL同步辐射设施以及尼尔森实验室的设备上进行。这项工作将与瑞典计算化学小组进行理论合作。水是最重要的环境和生命过程的反应介质。水的许多独特的化学和物理性质是由于它倾向于与自身和其他物质形成氢键。尼尔森教授和他的团队的工作旨在更好地描述液态水中的氢键网络。在尼尔森实验室工作的学生将有机会在该国首屈一指的光源之一工作，并将进一步受益于国际合作。除了密切参与研究工作外，尼尔森教授还是一位杰出的科学大使，参加了斯坦福大学和旧金山探索博物馆的一系列公共宣传活动。
