Simulation of Current Density for Electroplating on Silicon Using a Hull Cell

F. Lima[1], U. Mescheder[1], H. Reinecke[3]
[1]Hochschule Furtwangen University, Furtwangen, Baden-Wuerttemberg, Germany
[3]Institut für Mikrosystemtechnik, Freiburg im Breisgau, Baden-Wuerttemberg, Germany

Electrodeposition has a major advantage over other methods of thin film deposition. It allows deposition at atmospheric pressure and room temperature, requiring inexpensive equipment. However, there are several parameters which can influence an electroplated metal layer quality. The ... Saiba Mais

Microscale Simulation of Nanoparticles Transport in Porous Media for Groundwater Remediation

F. Messina[1], M. Icardi[1], D. Machisio[2], R. Sethi[1]
[1]Politecnico di Torino - DIATI, Torino, Italy
[2]Politecnico di Torino - DISAT, Torino, Italy

Nanoscale zerovalent iron is a promising reagent for the remediation of contaminated groundwater. The aim of the study is to simulate the transport of iron nanoparticles and their interaction with the porous media, their attachment and deposition on the soil grains. The particles ... Saiba Mais

Modeling Microwave Chiral Material Based On Crank Resonators Arrays Using COMSOL Multiphysics

J. Muñoz[1], G.J. Molina [1], M.M. Rojo[1]
[1]Dpto. Electromanetismo y Electrónica, Facultad de Química, Universidad de Murcia, Campus Espinardo, Murcia, Spain

Electromagnetic metamaterials present exotic and unusual properties hardly to be found in nature with many potential applications. They are usually built by distributing small resonant structures in periodical lattices. If the structure has chiral symmetry, the medium is called chiral ... Saiba Mais

Numerical Modeling of Heat and Mass Transfer in Porous Materials During Drying and Shrinkage

D. Lelièvre[1], P. Glouannec[1]
[1]Université de Bretagne-Sud, Lorient, France

Drying is an essential step in many manufacturing processes, for it will have an important impact on the product quality. This is why many numerical models have been realized over decades, in order to predict the hygrothermal behavior of porous media during the drying process. In this ... Saiba Mais

Comparison of Heat and Mass Transport at the Micro-Scale

E. Holzbecher[1], S. Oehlmann[1]
[1]Georg-August Universität Göttingen, Göttingen, Germany

Phenomena of heat and mass transfer are often compared, in various porous media applications. Questions of practical interest are, for example, if tracers can be used for the prediction of heat flow, or vice versa if heat can be utilized as, possibly retarded, tracer for predicting the ...

Ampacity Simulation of a High Voltage Cable Used in Offshore Wind Farms

E. Pelster[1]
[1]Wenger Engineering, Ulm, Germany

The ampacity of a cable depends on the cross section of its conductor. When selecting a cable design for a specific application it is of interest to choose the lowest possible conductor cross section in order to reduce material costs. Therefore an exact calculation of the ampacity is ... Saiba Mais

Electrochemical Impedance Spectroscopy of a LiFePO4/Li Half-Cell

M. Cugnet[1], I. Baghdadi[1], M. Perrin[1]
[1]INES - CEA, Grenoble, France

This study demonstrates that a multiphysics model of a LiFePO4/Li half-cell can be applied to simulate the impedance results from an EIS. However, it implies that the double layer capacitance has to be taken into account, since it is responsible of the semi-circle in the impedance ... Saiba Mais
