This renewal award will continue support of the Rensselaer Polytechnic Institute MRG glass science group. Its research is focused on chemical and microstructural aspects of glass stability. Topics of a chemical nature include diffusion of water into glass, dissolution rates of glass in aqueous solutions, rates of attack in seawater, stability of fluoride and chalcogenide IR transmitting glasses, and defects in ion- implanted silica glass. Additional research deals with glass structure: influence of dissolved volatiles on phase separation and phase stability, structural relaxation processes, light scattering and phonon attenuation mechanisms, behavior under high pressure, and effects of nitrogen doping. The collaborative, multi-investigator group includes four faculty from materials engineering, one from physics, and one from geology.

该更新奖将继续支持Rensselaer理工学院MRG Glass Science Group。 它的研究集中在玻璃稳定性的化学和微观结构方面。 化学性质的主题包括将水扩散到玻璃中，玻璃在水溶液中的溶解速率，海水的攻击速率，氟化物和甲状腺素化IR传播玻璃的稳定性以及离子植入的二氧化硅玻璃中的缺陷。 其他研究涉及玻璃结构：溶解的挥发物对相位分离和相位稳定性，结构弛豫过程，光散射和声音衰减机制，高压下的行为以及氮掺杂的影响。 该协作，多启动分组组包括来自材料工程的四个教职员工，一个来自物理学的教职员工，一个来自地质学的教师。
