SYMPOSIUM 4: Glass Technology and Crosscutting Topics
Glass can be engineered with a wide range of properties and in many forms to make it important in active and passive applications for current and emerging energy and environmental technologies. This symposium will draw an arc from the fundamental approaches (interplay of theory, modeling, and experiment) via material properties (compositional influences and signatures) and their characterization (in situ, ex situ) to manufacturing (novel processing techniques).
Session 1: Glass surfaces and treatments
The structure and composition of glass surfaces dominate their interactions with the environment and other materials. Glass surfaces are commonly treated (thermally, mechanically, or chemically) prior to use, with important implications upon the resulting functionality. Advancements in thermal poling, ion-exchange strengthening, corrosion inhibition, and coating adhesion will be discussed. This session will focus on fundamental understanding of glass surface chemistry, changes in surface chemistry from treatment and processing, and the performance of real material systems from controlled surface chemistry. Contributions will include corrosion phenomena, coatings, ion-exchange, thermal forming and tempering, and associated advancements in characterization.

Session 2: Chalcogenide materials for memory applications
Phase change and conducting bridge memory devices now are established as serious competitors to conventional nonvolatile computer memory. We propose the session will emphasize the following topics.
- Materials science of memory materials
- New directions (There are some very fresh ideas emerging, such as using PCMs for neuromorphic computing.)
- Modeling and simulation (materials and device modeling, simulation as tool for materials discovery)

Session 3: Challenges in glass manufacturing
Industrially fabricated glass is one of the most important materials used in society. New applications and compositions, more stringent quality requirements, increasing costs, and compliance with environmental regulations drive constant innovation in glass equipment and processes. New laboratory and modeling approaches have dramatically increased understanding of melting and forming processes and improved energy efficiency and equipment design. This session will cover recent developments.
- Physics and chemistry of melting and forming―experiments and modeling
- Energy efficiency―combustion, heat transfer, and new energy-saving technologies
- Furnace design and process control―sensors, flue gas chemistry, and emissions
- Corrosion and wear―refractories and electrodes
- New melting and forming concepts

Session 4: Waste immobilization—Waste form development: Processing and performance
This session will focus on the use of glasses and glass-ceramics for the immobilization of nuclear and hazardous wastes. The renewed interest in nuclear power generation and fuel reprocessing means that the processing, properties, and testing of vitreous materials also needs to be expanded. Similarly, treatment of hazardous waste for disposal or recycle is of current interest in many countries.
- Materials technologies for the vitrification and sintering of nuclear, hazardous, and toxic wastes, which includes waste immobilization in durable matrices
- New and innovative applications of materials and materials processes and alternative waste form materials and processing methods
- Waste-form performance and accelerated testing to assess chemical durability
- Modeling of glass and glass-ceramic dissolution over short and long timescales
- Characterization and properties of natural and archeological analogues
- Characterization and testing techniques to quantify waste form properties
