Identification of reaction and mass-transfer rates in gas-liquid reaction systems

Dominique Bonvin, Michael Amrhein, Nirav Pravinbhai Bhatt

This paper deals with the identification of reaction and mass-transfer rates from concentrations measured in gas-liquid reaction systems. It is assumed that the reactions take place in the liquid bulk only. The identification proceeds in two steps: (i) est ...

Liquid-phase sintering (LPS) is an industrial process used to consolidate materials composed of two different kinds of metallic and/or ceramic powders. At constant temperature, the amount of the present liquid-phase is constant. However, the shape of parti ...

Elsevier2010

A multi-domain finite element formulation has been applied to determine the semi-solid permeability of an equiaxed granular structure. The granular model was constructed from a Voronoï tessellation algorithm. The liquid-solid interface is represented impli ...

Photoelectrochemical properties of sensitized thin films

Mohamad Hojeij

In recent years, the fabrication of novel ultrathin film systems featuring multi-functionalities has been extensively studied due to their potential applications in photonics, sensors and solar cells. In a general sense, the primary goal of the present the ...

Crystallization of the resonating valence bond liquid as vortex condensation

Frédéric Mila, Dmitri Ivanov

We show that the liquid-to-crystal quantum phase transition in the Rokhsar-Kivelson dimer model on the two-dimensional triangular lattice occurs as a condensation of vortexlike excitations called "visons." This conclusion is drawn from numerical studies of ...

Liquid charge transporting material

Michael Graetzel, Shaik Mohammed Zakeeruddin, Henry Snaith

The present invention relates to optoelectronic and/or electrochemical devices comprising an organic charge transporting material which is liquid at a temperature of =180 DEG C. In particular in dye-sensitised solar cells, quantum efficiency higher than wi ...

Intense near-infrared luminescence of a mesomorphic ionic liquid doped with lanthanide b-diketonate ternary complexes

Jean-Claude Bünzli, Kurt Schenk

The ionic liquid 1-dodecyl-3-methylimidazole chloride ([C12- mim]Cl) is doped with 1 mol-% of the lanthanide ternary complexes [Ln(tta)3(phen)] (tta = thenoyltrifluoroacetonate, phen = 1,10-phenanthroline, Ln = Nd, Eu, Er, Yb), resulting in luminescent mes ...
