Symposium 08

Surface properties of glass

Lead Organizer

Seong Han Kim

Pennsylvania State University, USA

Description	Although there is sufficient knowledge on effects of glass bulk composition that can be used to optimize specific properties such as processability, mechanical strength, optical transparency, dielectric constant, etc., it is still very challenging to control the surface properties of glass to maximize performance in real situations. The complexity of problems encountered in glass surface science originates from, in many cases, surface reactions of glass in various environmental conditions, as well as physical contact with foreign objects during the manufacturing and storage of glasses and during service or operation in practical conditions. One of the most common examples is the adsorption of water to the surface in humid air; water can induce corrosion of the glass surface, affect the surface wear and mechanical strength, and influence the electrostatic charge transport phenomena. Thus, fundamental understanding of surface reactions of glass under various environmental conditions (both gaseous or liquid phases) and their impact on materials properties is critically important for practical applications and usage of glass. The same need extends similarly to other related systems such as coated or functionalized glass surfaces. All of these are the main subject of this symposium.

Symposium 10

Strengthening, mechanical and thermal properties of glasses and glass fibers

Lead Organizer

Yuanzheng Yue

Aalborg University, Denmark

Description	This symposium consists of two sessions: 1) Strengthening and mechanical properties; 2) Thermal properties. The mechanical properties of glass have become (one of) the most extensively studied subjects in inorganic glass science recently. This session will provide a valuable opportunity for scientists to present both the current understanding of glass fracture and the progress in developing glass and glass fibers strengthened by different means, e.g., physical, chemical and compositional strengthening process. The symposium concerns all the glass mechanical properties such as ductility, elasticity, local plastic flow, Poisson's ratio, tensile and compressive behavior. This session will deal with a wide range of glass materials including inorganic glasses, organic glasses, metallic glasses, as well as metal-organic framework glasses. The thermal properties are crucial to understanding the phase transitions, phonon transport and structure of glass. These properties are the key factors for developing new types of glasses and glass fibers. This session will provide a forum for scientists to present their progress both in understanding the thermal behaviors of glasses and in developing glasses with outstanding thermal performances. It concerns the thermal properties of bulk glasses, glass fibers, glass foams, glass ribbons, glass films, sealing glasses. It covers a wide range of subjects such as thermal expansion, heat capacity, thermal conduction, thermal shock resistance, fictive temperature, phase transitions, enthalpy relaxation, rejuvenation, ageing, and thermal cycling. The connection between the mechanical and the thermal properties will be discussed.

Symposium 12

Optical fibers, waveguides and devices

Lead Organizer

John Ballato

Clemson University, USA

Description	Last year alone, over 500,000,000 kilometers of optical fiber were manufactured globally. One might reasonably think that such commercial maturity precluded much need for significant innovation. However, despite this ubiquity, industrial drivers such as 5G communications (and associated Internet of Things, IoT), laser cutting / welding / machining, advanced environmental and infrastructure sensing, and defense and energy applications for high energy lasers demand constant and continuous advancements in fiber optic materials and manufacturing methods. This symposium welcomes fundamental and applied innovations and advancements in optical fibers and fiber-based devices. The over-arching objective of this symposium is to communicate the glass science and engineering of fiber optic materials and manufacturing to reduce roadblocks to fiber properties and performance, particularly those efforts that disruptively marry advanced compositional, process, and modeling innovations across commodity and specialty fiber platforms.

Symposium 14

Conventional uses of glass - flat, container and fibre products

Lead Organizer

Russell Hand

University of Sheffield, UK

Description	If a member of the general public thinks about glass the chances are that they will think of glass as the material used in windows, whether in buildings or vehicles; in bottles and jars; or in fibres for insulating buildings or reinforcing polymers. These conventional bulk uses of glass are the bedrock of the glass industry – and indeed a key foundation of glass science – and are all too easily “looked through” rather than “looked at”, especially as the commodity nature of these products makes innovation challenging. However, innovations in both processes and products are essential if bulk glass is to maintain its competitive edge in an ever changing world. This symposium will provide a forum for innovative thinking about commercial glasses and their applications. Thus it aims to present and discuss the latest developments in the bulk use of glass across flat, container and fibre industries. Contributions across the full range of technology readiness levels are welcomed. These may range from fundamental compositional developments through novel approaches in the use of glass in facades and structures to near-market process and product innovations.

Symposium 15

Glasses for waste immobilization and recycling

Lead Organizer

Cheon Woo Kim

Korea Hydro and Nuclear Power Co., Ltd., Korea

Description	Glass has long been recognized as a promising medium for use in remediating high and low-level radioactive wastes, and is now being investigated for remediation of a diverse range of hazardous wastes, such as asbestos-containing waste and incinerator ash. Vitrification is to incorporate waste in the stable glass matrix as waste is fed on the glass melt. Vitrification destroys hazardous organics and immobilizes heavy metals and radioactive elements to form a chemically durable and highly leach-resistant vitrified form. Especially, vitrification process in the field of combustible LLW treatment provides exceptional volume reduction and is attractive for minimizing disposal volume. This session will focus especially on various R&D results gained from the glass formulation development using borate and silicate glasses, iron-phosphate glass, etc. The physicochemical properties including viscosity and electrical conductivity of the glass melt, solubility and redox behavior of oxides, chemical durability of the vitrified form, etc. will be presented and discussed. In addition, the session will provide the vitrification process quality from the lab- and/or pilot-scale demonstration tests by using JHCM, CCIM, In-can Melter, PTM, etc. Vitrification process by using a lab-scale CCIM will be presented and discussed for a rare-earth oxide waste generated from the pyro-processing. Vitrification process by using PTM will be presented and discussed for an asbestos-containing hazardous material which was simulated for a decommissioning waste. If possible, recent vitrification demonstration tests using the simulated Fukushima ALPS wastes will be presented as an invited speech. Finally, several operational experiences from the commercial vitrification facilities will be presented and discussed.

Symposium 17

Glass under extreme conditions

Lead Organizer

Morten Mattrup Smedskjaer

Aalborg University, Denmark

Description	The structure and properties of glasses depend not only on the temperature, pressure, and composition, but also on their complete formation history, e.g., thermal and pressure histories. By understanding the response of glasses to extreme conditions, such as high temperature, pressure, stress, cooling rate, and irradiation, it is possible to design them in a way to withstand such conditions, as well as to utilize such conditions to synthesize them with superior properties. However, despite recent efforts of glass scientists, numerous challenging questions concerning the above-mentioned issues still remain unanswered. Session topics include, but are not limited to, preparation of glasses using aerodynamic levitation, hyperquenching and vapor deposition techniques, access to forbidden glassy states, response of glasses to high-pressure, high-stress, highly reactive conditions, irradiation, extreme rejuvenation or aging, etc. Both experimental and computational studies will be considered and presentations of advanced tools for the in situ and ex situ characterization of these materials will be welcomed.

Symposium 18

Challenges for solution processing of glasses: monolithic composite, thin films and nano materials toward functionalities

Lead Organizer

Masahide Takahashi

Osaka Prefecture University, Japan

Description	Solution processing, represented by Sol-Gel approach, offers new molecular approach to glassy materials with unprecedented functionalities. In other words, we can synthesize materials with desired functionalities in electronics, photonics and mechanics via a rational “molecular design”, like organic chemists! For example, organic-inorganic hybrid composites can be easily obtained because the maximum temperature of the processing is limited by the boiling point of the solvent. One of advantages of such hybrids is explained by that the resultant materials possess high functionality from organic components and industrial reliability by inorganic moieties. This session will provide great opportunity to discuss on the recent innovation of the processing, resultant materials, and functionalities. The session topic includes processing of glassy materials in variety of shapes (bulk, thin films and nano objects), new functionalities in electronics, photonics, magnetics, and other applications.
