Electrochem. promotion (EP) of gas-phase catalysis with O2--conducting solid electrolytes is addressed. The behavior of the ref. electrode, prepd. by deposition of a gold film, was found to be quasi-reversible, 12O2/O2- being the potential detg. redox coup ...
Based on microstructure measurements in a simply shaped lake basin, the sources of vertical mixing in the stratified part of the water body were identified and estimates of their relative importance obtained by balancing turbulent kinetic energy introduced ...
The Bases of Chemical Thermodynamics: Volume 1 In this volume (volume 1), the fundamental aspects of thermodynamics are presented. The first and second laws of thermodynamics are illustrated. The need to define thermodynamic temperature and the nature of e ...
Free surface flows are extremely complex and appear in various cases such as chemistry, oceanography, thermodynamics and turbomachinery. Their complexity is due to the fact that they are composed of two distinct phases which are only separated by a thin in ...
The Bases of Chemical Thermodynamics: Volume 2 In this volume (volume 2), the tools necessary to study and understand systems in which chemical reactions can take place are developed. The variables of reaction are the keys to this understanding. Criteria f ...
The second law of thermodynamics is often expressed as the fact that the entropy of an isolated system increases when a spontaneous change takes place. While this statement is true, a more general formulation can easily be presented to students. Starting f ...
Chemical reactions and chemical equilibria. Thermodynamics of ideal and real solutions. Statistical Mechanics, microcanonical ensemble, canonical ensemble. ...
Below -60 and without catalyst, 1.2-dimethylidenecyclopentane (16), 1,2-dimethylidenecyclohexane (13), 1,2-dimethylidenecycloheptane (17), and 1,2-dimethylidenecyclooctane (18) add to sulfur dioxide in the hetero-Diels-Alder mode, giving the corresponding ...
In this work, we are interested in elaborating models and numerical methods in order to study some phenomena which arise in the solidification of binary alloys. We propose two distinct models based on the mass and energy conservation laws as well as on cla ...
The development of a conceptual framework to test different viscoelastic constitutive laws is presented. This framework has the advantage of satisfying a priori the thermodynamic restrictions and is valid for large deformations. In addition, the different ...
