9614531 Angell This focus of this investigation of glasses and amorphous liquids is on five broad areas: polyamorphic transitions and possible connections with biopolymers; studies of microemulsion systems with an emphasis on glass-forming microemulsions; studies of Vogel-Fucher deviations in thermodynamic properties; studies of molecules which may exhibit two-state complexity; and destablization of the crystal phase by electrochemical methods, and by crystal desolvation. %%% The amorphous state of solids is central to many areas of advanced materials technologies involving areas such as polymers, ceramics, metals and pharmaceuticals. Research investigations such as this aimed at describing at the molecular level the nature of the amorphous state and how it is prepared and stabilized will lead possibly to new routes for synthesizing new materials with unique properties. ***

小行星9614531 玻璃和无定形液体研究的重点是五个广泛的领域：多晶转变和与生物聚合物的可能联系;微乳液系统的研究，重点是玻璃形成微乳液;热力学性质的Vogel-Fucher偏差的研究;可能表现出两态复杂性的分子的研究;以及通过电化学方法和通过晶体去溶剂化使晶相稳定。 固体的无定形状态是许多先进材料技术领域的核心，涉及聚合物、陶瓷、金属和制药等领域。 诸如此类的研究调查旨在在分子水平上描述非晶态的性质以及它是如何制备和稳定的，这可能会导致合成具有独特性能的新材料的新途径。 ***
