US-Sweden Cooperative Science: Hydrogen in Transition MetalP-Element Compounds

该奖项将支持佛蒙特大学Ted Flanagan博士和瑞典乌普萨拉大学无机化学系S. Rundqvist教授之间的合作研究。该项目的目的是研究氢在一系列具有金属磷化物化学计量的金属p元素化合物中的溶液（和氢化物的形成）。它们都有相同的四边形Ti - P结构。氢溶液的热力学测量将在佛蒙特大学进行，氢（氘）在晶格中的位置的结构测定将在瑞典使用中子衍射进行。这两种方法的结合是可取的，因为它将允许对结果作出更完整的解释。了解这些系统的行为是很重要的，因为它们与某些技术感兴趣的相关系统有共同的特征，例如硅和非晶合金中的氢。

This award will support collaborative research between Dr. Ted Flanagan, University of Vermont, and Professor S. Rundqvist, Department of Inorganic Chemistry, University of Uppsala, Sweden. The objective of the project is to investigate the solution of hydrogen (and hydride formation) in a series of metal p-element compounds which have the stoichiometry of metal phosphides. These all have the same tetragonal Ti P structure. The thermodynamic measurements of hydrogen solution will be made at the University of Vermont and the structural determinations of the hydrogen (deuterium) positions in the lattices will be carried out in Sweden using neutron diffraction. The combination of the two approaches is desirable, becuase it will allow a more complete interpretation of the results to be made. The understanding of the behavior of these systems is important because they have features in common with related systems of some technological interest, e.g. H in silicon and amorphous alloys.
