Due to COVID-19 (Coronavirus) the GOMD meeting is rescheduled for August 2-6. The NEW DATE for Nucleation and Crystallization in Glasses course is August 1-2
Nucleation, Growth and Crystallization in Glasses—Fundamentals and Applications
Saturday August 1, 2020 (3-6 p.m.) and Sunday, August 2, 2020 (9:00 a.m.–noon)
Hotel Monteleone, New Orleans, Louisiana - Held in conjunction with GOMD 2020
Instructor: Edgar Zanotto, Center for Research, Technology and Education in Vitreous Materials, Federal University of São Carlos, Brazil
Learn the theories of nucleation, growth, and overall crystallization
After completing the course and homework, participants will learn how to apply these theories to avoid spontaneous devitrification to produce new glasses, as well as start designing some glass-ceramics having simple nano or microstructures.
Who Should Attend
This course is aimed at those interested in an updated, high level, introduction to the intricate (dynamic and thermodynamic) processes that control crystal nucleation, growth and overall crystallization of glasses, including industry professionals, post-graduates, and advanced undergraduate students. This knowledge is key to the production of novel glasses and for the development of new or improved glass-ceramics. It is recommended that the participants have a significant background in materials science or engineering, chemistry or physics. Previous knowledge and experience in glass science would be beneficial.
- Relevance of crystal nucleation, crystal growth and overall crystallization for the understanding of the vitreous state, as well as for glass and glass-ceramic technology.
- Crystal nucleation in glass-forming liquids: phenomenology, experimental methods, homogeneous and heterogeneous nucleation, surface crystallization, non-steady state effects, classical nucleation theory (CNT), experimental tests of CNT, metastable phase formation, temperature and size dependent surface energy, the courtyard effect, the effect of elastic stresses, maximum nucleation rates (Imax) versus glass transition temperature (Tg).
- Crystal growth in glass-forming liquids: growth models, experimental methods (OM, DSC, etc.), tests with several glasses, growth rate maxima, Umax vs. Tgr, the breakdown of the Stokes-Einstein-Eyring equation.
- Overall crystallization: JMAK (Johnson-Mehl-Avrami-Kolmogorov) – model, experimental methods, tests with some glasses, critical cooling rates for vitrification, glass-forming ability, glass stability against crystallization
- Glass-ceramics (GC): Historical development, existing glass-ceramics, new GC that are yet in the development stage, such as: large grain transparent GC, bioactive GC, sintered GC, PTRG and Laser crystallized GC.
Edgar Dutra Zanotto is professor of materials science and engineering at the Federal University of São Carlos (UFSCar) in Brazil, and director of the Center for Research, Technology, and Education in Vitreous Materials (CeRTEV). He is an editor of the Journal of Non-Crystalline Solids. Zanotto chaired 6 of the most important glass congresses and delivered over 300 conference presentations, which include approximately 130 invited and 30 plenary talks. He is a member of 6 science academies. He has received 53 awards, including several glass awards and distinctions, for example, ICG's Gottardi Prize, the JNCS Zachariasen Award, the ACerS Morey Award, and the Turner, Cooper, and Scholes award lectures. Zanotto's studies include fundamental research on the crystallization kinetics and properties of glasses and glass-ceramics. His research work encompass rigorous tests, improvement or development of nucleation and growth models for glasses, the effects of liquid phase separation on nucleation, surface crystallization kinetics, overall crystallization, glass stability versus glass-forming ability, correlations between molecular structure and nucleation mechanism, sintering with simultaneous crystallization, diffusion processes controlling crystallization, as well as mechanical, rheological, thermal and biochemical properties of glasses and glass-ceramics. More recently, he has been working on the use of Artificial Intelligence techniques for the design of new glasses. The technological branch of Zanotto's team includes projects in partnership with over 25 companies over the last four decades. He has registered 27 patents. He is also interested in the development or improvement of glass-ceramics with improved or new functionalities. He has published over 300 scientific articles, 20 book chapters, and 2 books on glass science and technology.
