Daniel Roberto Cassar holds a Ph.D. in Materials Science and Engineering from the Federal University of Sao Carlos (UFSCar), and a BSc in Materials Engineering with an emphasis in polymeric materials from the same institution. He currently performs research in glass science, glass formation, and crystallization processes as a postdoctoral fellow at the Vitreous Materials Laboratory of UFSCar, part of the Center for Research, Technology, and Education in Vitreous Materials (CeRTEV), under the supervision of Professor Edgar Dutra Zanotto. His interests include glass materials, crystal nucleation and growth, equilibrium and non-equilibrium viscosity, relaxation, and diffusion processes. He is also interested in applying machine learning algorithms to induce models that can predict the properties of materials. (Source: Lattes Curriculum)
Heated glasses undergo a variety of kinetic processes that are very important both scientifically and technologically, such as crystallization. When controlled, crystallization is the key to make glass-ceramics but it must be avoided in order to make a glass. In this research we will study some microscopic aspects of crystallization. For example, we want to investigate the eluding "diff...
The Stokes-Einstein/Eyring (SEE) equations are frequently used to estimate the effective diffusion coefficients that control crystallization by using viscosity data. Such equation is accepted for low to medium values of viscosity (10^-1 - 10^5 Pa.s) but has been questioned for higher viscosities (near 10^12 Pa.s). Nucleation and crystal growth mechanisms have received increasing attenti...
