Molecular explanation for the abnormal flux of material into a Hot Spot in Ester Monolayers
(American Chemical Society, 2017-06)
Langmuir monolayers of certain surfactants show a negative derivative of the surface pressure with respect to temperature. In these monolayers, a local temperature gradient leads to local yielding of the solid phase to a ...
Prediction of effectiveness factor using one-dimensional approximations for complex pellet shapes and abnormal kinetics expressions
(American Chemical Society, 2013-04-30)
This contribution undertakes the evaluation of one-dimensional (1D) models to approximate the behavior of actual three-dimensional (3D) catalyst pellets, in the case of abnormal kinetics and close to the limit of steady ...
Growing Fe-Mn-Al-Ni single crystals by combining directional annealing and thermal cycling
(Elsevier Science SA, 2020-01)
In pseudoelastic alloys, a fine-grained microstructure implies restrictions on the propagation and shrinkage of the martensitic phase. Thus, the pseudoelastic effect is adversely affected. For this reason, thermomechanical ...
Caracterización térmica de solidos mediante la técnica fotoacústica con normalización usando muestras líquidas
(2011-01-25)
RESUMEN: El desarrollo de metodologías para la medición de la capacidad calorífica específica de sólidos es un tema de importancia debido a la sensibilidad de este parámetro a defectos estructurales, dopaje, cambios de ...
Efeito do sombreamento artificial no desempenho e parâmetros reprodutivos de novilhos brangus em semiconfinamento
(2015-01-01)
Thirty Brangus bulls were used in a 90-d study to assess the effect of artificial shading on the performance and reproductive characteristics of semi-confined cattle. Animals were kept in four one-ha paddocks in two groups ...

Hard versus soft dynamics for adsorption-desorption kinetics: Exact results in one-dimension
(American Physical Society, 2009-11-12)
The adsorption-desorption kinetics is discussed in the framework of the kinetic lattice-gas model. The master equation formalism has been introduced to describe the evolution of the system, where the transition probabilities ...
