Glasses are ubiquitous across materials types and technological applications but their structure – property – processing relationships and underlying fundamental physics remain poorly understood. IRG 1 uses cross-fertilization of ideas and techniques from organic and inorganic glasses to address fundamental problems in glass science through the lens of stability. Glasses of the same composition can be created in states of widely varying thermodynamic and kinetic stability. The IRG seeks to use these materials to develop fundamental stability-structure-property relationships for glasses. Efforts include establishing control over stability in organic and inorganic glasses; understanding the structures associated with varying states of stability ; discovering the molecular nature of polyamorphism – the existence of two stable liquid states of the same substance; and determining the relationship between the structure and dynamics of liquids as they cool into the glassy state. The IRG integrates theory, simulations, and experiments to expand the range of ultrastable glassy materials and to enable new applications in areas as diverse as hard coatings and quantum information.
