The unusual dynamical and mechanical properties of viscous liquids and glasses underpins many existing and emerging technologies, from lubrication to the strength and fragility of bulk metallic glasses. An improved understanding of how macroscopic properties such as viscous flow, ductility and fracture emerge from the microscopic interactions between atoms and molecules will provide the enabling scientific knowledge for exploiting the properties of such materials on the nanoscale. National expertise in this area will help establish and strengthen international collaboration with leading research institutes in the field.

粘性液体和玻璃异常的动力学和机械特性支撑着许多现有和新兴技术，从润滑到块体金属玻璃的强度和脆性。更好地理解粘性流动、延展性和断裂等宏观特性如何从原子和分子之间的微观相互作用中产生，将为在纳米尺度上开发此类材料的特性提供有利的科学知识。该领域的国家专业知识将有助于建立和加强与该领域领先研究机构的国际合作。
