Machine learning unveils composition-property relationships in chalcogenide glasses
Saulo M. Mastelini, Daniel R. Cassar, Edesio Alcobaça +3
Due to their unique optical and electronic functionalities, chalcogenide glasses are materials of choice for numerous microelectronic and photonic devices. However, to extend the r…
Is the Structural Relaxation of Glasses Controlled by Equilibrium Shear Viscosity?
Ricardo F. Lancelotti, Daniel R. Cassar, Marcelo Nalin +2
Knowledge of relaxation processes is fundamental in glass science and technology because relaxation is intrinsically related to vitrification, tempering as well as to annealing and…
Designing optical glasses by machine learning coupled with a genetic algorithm
Daniel R. Cassar, Gisele G. dos Santos, Edgar D. Zanotto
Engineering new glass compositions have experienced a sturdy tendency to move forward from (educated) trial-and-error to data- and simulation-driven strategies. In this work, we de…
ViscNet: Neural network for predicting the fragility index and the temperature-dependency of viscosity
Daniel R. Cassar
Viscosity () is one of the most important properties of disordered matter. The temperature-dependence of viscosity is used to adjust process variables for glass-making, from mel…
Which glass stability parameters can assess the glass-forming ability of oxide systems?
Jeanini Jiusti, Daniel R. Cassar, Edgar D. Zanotto
Glass forming ability (GFA) is a property of utmost importance in glass science and technology. In this paper, we used a statistical methodology---involving bootstrap sampling and…
Critical assessment of the alleged failure of the Classical Nucleation Theory at low temperatures
Daniel Roberto Cassar, André Hofmeister Serra, Oscar Peitl +1
The Classical Nucleation Theory allegedly fails to describe the temperature dependence of the homogeneous crystal nucleation rates below the temperature of maximum nucleation, $T_{…
