The outer and less strongly bound electrons of matter are responsible for most material properties including color, chemical-bonding capacity, hardness, magnetism, band gap, electronic structure, and catalytic activity to electrical and heat conductivity and even super-conductivity. Having the means to measure, model, and understand the outer electrons of a material gives us the key to understanding and tailoring important physical properties. This research will employ soft X-ray spectroscopy with synchrotron radiation to answer key questions concerning the structure of new materials in 3 areas of focus:

物质的外层电子和弱束缚电子决定了大多数材料特性，包括颜色、化学键合能力、硬度、磁性、带隙、电子结构以及对导电性和导热性甚至超导性的催化活性。拥有测量、建模和理解材料外层电子的方法，为我们提供了理解和定制重要物理特性的关键。这项研究将采用软 X 射线光谱与同步加速器辐射来回答有关 3 个重点领域的新材料结构的关键问题：
