U.S.-Switzerland Cooperative Research: Multinuclear Nuclear Magnetic Resonance (NMR) Investigations of Superionically Conducting Glasses

该奖项将使爱荷华州立大学的Steve W.Martin博士能够与瑞士苏黎世大学的Detlef Brinkmann博士合作。他们将研究可能应用于高能量和高密度固态电池的优良导电玻璃。具体地说，他们将研究各种银离子系统、碱离子系统和玻璃的高压核磁共振(核磁共振)。他们将在原子水平上探索阳离子传导过程的动力学，以确定迁移机制，静电和应变能项对传导能量学的相对贡献，以及可移动阳离子的比例。他们的研究将测试玻璃中几种流行的离子传导模型的适用性。此外，他们还将试图确定碱的迁移机制是否类似于银材料中的机制。作为一名年轻的玻璃科学研究人员，马丁博士有着良好的记录，他将从与布林克曼博士的合作中受益，布林克曼博士以使用核磁共振表征超导晶体而闻名。由于瑞士实验室的实验能力，他们将有机会在高压下检查多核核磁共振。

This award will enable Dr. Steve W. Martin, Iowa State University, to collaborate with Dr. Detlef Brinkmann, University of Zurich, Switzerland. They will study superionically conducting glass for possible applications to high energy and density solid-state batteries. Specifically, they will examine various silver-ion systems, alkali-ion systems, and high pressure nuclear magnetic resonance (NMR) of glass. They will probe the dynamics of cation conduction processes on the atomic level to determine the migration mechanisms, the relative contributions of the conduction energetics by electrostatic and strain energy terms, and the fraction of mobile cations. Their research will test the appropriateness of several popular models of ionic conduction in glass. In addition, they will try to determine if alkali migration mechanisms are similar to those in silver materials. Dr. Martin has a good record as a young researcher in glass science and he will benefit from working with Dr. Brinkmann, who is known for his use of NMR to characterize superionic conducting crystals. Because of the experimental capability of the laboratory in Switzerland, they will have an opportunity to examine multinuclear NMR under high pressures.
