An effective hydrogen diffusion coefficient has been calculated for two solidifying Al - 4.5 wt.% Cu and Al - 10 wt.% Cu alloys as a function of the volume fraction of solid. For this purpose, in situ X-ray tomography was performed on these alloys. For eac ...
The paper describes a level set framework for the finite-element modelling of recrystallization in polycrystalline materials, including the nucleation, primary recrystallization and grain growth stages. A set of convection- reinitialization-diffusion equat ...
Numerical calculations of the evaporation kinetics of bulk volatile liquids and of water from smectite clay granules are compared with experimental results. The weight loss of the volatiles is analyzed by thermogravimetry and differential calorimetry. Unde ...
CuO have potential applications in various fields, such as gas sensors, solar energy and catalysis. With the aim of trying to obtain CuO with a high specific surface area, an oxalate precipitation route followed by thermal decomposition was studied. Four d ...
Under broad assumptions, breaking of Lorentz invariance in gravitational theories leads to tension with unitarity because it allows for processes that apparently violate the second law of thermodynamics. The crucial ingredient of this argument is the exist ...
Following the analytic approach to thermodynamics developed by Stuckelberg, we study the evolution equations of a closed thermodynamic system consisting of point particles in a fluid. We obtain a system of coupled differential equations describing the mech ...
The present book is the result of more than half a century of teaching and research in thermodynamics at the Swiss Federal Institute of Technology (Ecole Polytechnique Fédérale of Lausanne), known as the EPFL, in Switzerland. Its objective is to facilitate ...

We study some mechanical problems in which a friction force is acting on a system. Using the fundamental concepts of state, time evolution and energy conservation, we explain how to extend Newtonian mechanics to thermodynamics. We arrive at the two laws of ...
The aim of this contribution is to review the application of thermodynamics to live cultures of microbial and other cells and to explore to what extent this may be put to practical use. A major focus is on energy dissipation effects in industrially relevan ...
In the prospect of reducing the greenhouse gas emissions contributing to the global warming the study of CO2 capturing processes is essential. The purpose of this project would be to study more in detail the chemical absorption with amines for CO2 separati ...
