Solving heat conduction problems with phase-change under the heat source term approach and the element-free Galerkin formulation
(Pergamon-Elsevier Science Ltd, 2019-07)
The present work has been conducted in order to introduce an alternative solution for heat transfer problems with phase-change and moving boundaries, via the element-free Galerkin (EFG) method. In this novel approach, the ...
Simultaneous calculation of chemical and phase equilibria using convexity analysis

Two-phase Stefan problem with nonlinear thermal coefficients and a convective boundary condition
(Pergamon-Elsevier Science Ltd, 2021-04)
A solidification process for a semi-infinite material is presented through a non-linear two-phase unidimensional Stefan problem, where a convective boundary condition is imposed at the fixed face x=0. The volumetric heat ...
Rotating disk sorptive extraction of cu-bisdiethyldithiocarbamate complex from water and its application to solid phase spectrophotometric quantification
(Japan Society for Analytical Chemistry, 2014)
This study demonstrates the first use of polydimethylsiloxane (PDMS) immobilized on a rotating disk for the extraction of copper from aqueous matrices and its subsequent direct determination by solid phase UV-Visible ...
Nondegeneracy and stability in the limit of a one-phase singular perturbation problem
(Amer. Inst. Mathematical Sciences-AIMS, 2023)
We study solutions to a one-phase singular perturbation problem that arises in combustion theory and that formally approximates the classical one-phase free boundary problem. We introduce a natural density condition on the ...
Understanding Chemical Equilibrium: The Role of Gas Phases and Mixing Contributions in the Minimum of Free Energy Plots
(American Chemical Society, 2017-03)
The use of free energy plots to understand the concept of thermodynamic equilibrium has been shown to be of great pedagogical value in materials science. Although chemical equilibrium is also amenable to this kind of ...
