Stability of Glasses

这一更新奖项将继续支持伦斯勒 理工学院MRG玻璃科学组。 其研究 专注于玻璃的化学和微观结构方面 稳定 化学性质的主题包括扩散 玻璃在水溶液中的溶解速率 解决方案，在海水中的攻击率，氟化物的稳定性， 硫系红外透射玻璃，以及离子- 植入石英玻璃。 其他研究涉及玻璃 结构：溶解挥发物对相分离的影响 和相稳定性，结构弛豫过程，光 散射和声子衰减机制，高 压力和氮掺杂的影响。 合作， 多研究者小组包括四名教师， 一个是工程学，一个是物理学，一个是地质学。

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.
