Session 3: Structural characterizations of glasses and melts

This session will present on recent advances on the structural characteristics of glasses and melts, crucial for both research and industrial applications. Contributions are sought on basic glass characterization and correlations between structure, properties, and processing. Highlighted techniques include magnetic resonance spectroscopy, X-ray, neutron, and light scattering, as well as X-ray absorption and emission spectroscopy, vibrational spectroscopy, and scanning probe and electron microscopies. Key topics encompass spectroscopic studies to reveal the structures of glasses and melts, but also experimental measurements of physical properties (viscosity, density, diffusivity, elemental partitioning), and computational methods such as molecular dynamics simulations and ab initio calculations.This session aims to bring together specialists in the structural aspects of glasses and melts, as well as those working on macroscopic properties. It will provide a global view of glasses and liquids and cross the boundaries between them.

Session 4: Atomistic simulation and predictive modeling of glasses

Modeling and simulation are integral to advancing materials research, especially in the realm of glass, ceramics, amorphous and nanostructured materials, which possess intricate characteristics and challenges to characterize experimentally. This session aims to delve into sophisticated computer simulations and modeling approaches employed to unravel the structures, properties, and behaviors of glasses and glass-forming liquids. We particularly seek to explore the latest advancements and applications of first-principles, classical, and mesoscale methods, with a focus on their integration to expand the spatial and temporal scales traditionally explored by conventional modeling techniques. Additionally, we encourage numerical investigations that facilitate the interpretation of experimental data and structural validation, utilizing techniques such as X-ray and neutron diffraction, solid-state NMR, and various spectroscopic methods. As an emerging technology, we will also highlight applications of machine-learning interatomic potential in this domain.

Session 5: Data-driven modeling and machine learning for glass science

Data-driven methods and artificial intelligence-based models have attracted much attention in recent years to solve complex problems in the field of glass science. In particular, machine learning has been successfully applied to solve long-standing problems, such as predicting composition–property relationships, developing optimized glass compositions, accelerating glass modeling, and even understanding some fundamental aspects of the glass transition. This session will focus on recent advances in the use of machine learning and artificial intelligence in glass science, technology, and modeling. Topics of interest include, but are not limited to, the application of machine learning and artificial intelligence to develop and interpret composition–property relationships, design optimized glass compositions, 3D printing and additive manufacturing of glasses, advanced computational modeling by developing machine-learned interatomic potentials and accelerating glass simulations, image processing, predicting the structure of glasses, identifying key structural patterns/descriptors that govern glass properties, and understanding the fundamentals of the glassy state.

Session 6: Mechanical properties of glasses

This session will discuss the mechanical properties of disordered materials across multiple scales while bridging the fields of oxide and non-oxide glasses, as well as mechano-optical and mechanoelectrical couplings. We will consider the structural origin of elasticity, plasticity, and fracture with the objective of designing glasses with superior toughness, defect tolerance, and stiffness, combining mechanical and various functional properties. Particular attention shall be given to the identification of general, material-independent constitutive laws, which may be used as guidelines to improve the mechanical properties; the combination of experimental approaches and computational modeling of the stress response of glasses and early stages of damage infliction; and the interplay between size and time effects, stress corrosion, and the chemical aspect of fracture. The topics covered in this session include, but are not limited to, the following:

• Dynamic fracture and brittleness, or crack initiation, including the application of in-situ techniques
• Slow crack growth and stress corrosion cracking, the underlying chemistry and transport phenomena in high-stress fields
• Multiscale investigation of elasticity, plasticity, and hardness in relation to bulk topology through combining mechanical analyses with structural analyses
