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…
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_{…
Solving the Classical Nucleation Theory with respect to the surface energy
Daniel R. Cassar
An essential parameter of the Classical Nucleation Theory (CNT) is the surface energy between a critical-size nucleus and the ambient phase, . In condensed matter, this paramete…
