In this project, we will establish a unified description of supercooling, viscoelasticity, and vitrification in a family of molecules-the transition metal alkoxides-whose behaviour bridges that of polymers and small-molecule glass formers. The temperature-dependent properties of materials are of enormous importance to their practical application and therefore a thorough understanding of the molecular origin of these properties is critically important. A wide range of techniques will be used including advanced rheology down to -160C, DSC, Raman, and SAXS/WAXS to characterise macroscopic properties. This is combined with atomistic computer simulations (by collaborators) to provide insights into molecular level structure and dynamics responsible for the macroscopic behaviour. Our overall aim is then to forge a deep connection between polymer and glass physics in order to produce a paradigm shift in fundamental materials science that will ultimately lead to a more rational design of amorphous materials with implications for all areas where glasses are utilised from polymer, oxide, chalcogenide, metallic, organic, to metal-organic framework (MOF) glasses involving applications from amorphous drugs, ultra-strong metallic glasses used in airplane engines, optoelectronic materials, to containment for high-level nuclear waste.

在这个项目中，我们将在一个分子家族中建立对超冷，粘弹性和玻璃化的统一描述 - 过渡金属烷氧化物 - 构成了聚合物和小分子玻璃板的行为桥梁。材料的温度依赖性特性对其实际应用至关重要，因此对这些特性的分子起源有透彻的理解至关重要。将使用广泛的技术，包括先进的流变学向-160C，DSC，Raman和Saxs/Waxs来表征宏观特性。这与原子计算机模拟（由协作者）结合使用，以提供对宏观行为负责的分子水平结构和动力学的见解。然后，我们的总体目的是建立聚合物和玻璃物理学之间的深厚联系，以产生基本材料科学的范式转移，最终将导致更合理地设计无定形材料的设计，对所有玻璃的镜头均采用聚合物，氧化物，氧化物，甲状腺素，金属层，有机物，有机物，Meter-Organigry（Meter-Organigent）的玻璃（Met-Organigant）的玻璃（Meter-Ordrange）玻璃的所有区域，使得均具有飞机发动机，光电材料中使用的金属眼镜，用于高级核废料的遏制。
