Silver nanoparticles are valuable in the field of plasmonics since silver has a higher field enhancement factor compared to other metals that possess plasmonic properties. The plasmonic properties of silver nanoparticles can be finely tuned to the incident light wavelength through their ... Mehr lesen

Numerical Analysis of Radiant Heat Emission Systems

F. Ochs [1], M. Magni [2], M. Bianchi Janetti [1],
[1] University of Innsbruck, Unit for Energy Efficient Buildings, Innsbruck, Austria
[2] University of Bologna, Bologna, Italy

Radiant heating generally addresses all heat emission systems having a share of radiant heat emission greater than 50%, compared to a convector or fan coil where the heat is transferred mainly by means of convection. Recently, so-called infrared-heating systems are discussed as a cost ... Mehr lesen

2D Modeling of Elastic Wave Propagation in Solids Containing Closed Cracks

[1] Fraunhofer UMSICHT, Oberhausen, Germany

Fuel vapor restraint systems are used in vehicles to avoid discharge of volatile hydrocarbons from fuel tanks. The topic of this paper is the proper operation of fuel vapor restraint systems depending on the composition of bioethanol-fuel-blends. Experimental data serve as input to a ... Mehr lesen

A Modified Koutecký-Levich Equation for the Analysis of Electrochemical Flow Cells with Complex Geometries

[1] Paul Scherrer Institut, Villigen, Switzerland
[2] ETH Zürich, Zürich, Switzerland

Electrochemical flow cells have found widespread use in analytical chemistry due to their short response time, high sensitivity and selectivity. The geometrical flexibility and therefore, the ease of coupling the electrochemical to other experimental techniques has attracted considerable ... Mehr lesen

Numerical Simulations of Ion Cyclotron Range of Frequency (ICRF) Wave Fields in a Linear Plasma Device

Fusion devices (tokamaks, stellarators) require hundreds of millions degree Celsius temperature to reach the plasma state when the fusion reactions start to occur. Ion cyclotron resonance heating (ICRH) is a method of energy transfer to the ions in the plasma from electromagnetic ... Mehr lesen

Simulating Organogenesis with COMSOL Multiphysics® software: Phase-Field Based Simulations of Embryonic Lung Branching Morphogenesis

L. D. Wittwer [1], R. Croce [1], D. Iber [1],
[1] ETH Zürich, Zurich, Switzerland

While many biological details in organogenesis have been uncovered, fundamental questions regarding the control of growth and shape during lung and kidney morphogenesis remain unsolved. Using mathematical models, we recently showed that only ligand-receptor based Turing models ... Mehr lesen

Determination of the Load-dependent Thermal Conductivity of Porous Adsorbents

O. Kraft [1], J. Gaiser [1], M. Stripf [1],
[1] University of Applied Sciences, Karlsruhe, Baden-Würtemberg, Germany

Standard measuring techniques for thermal conductivity cannot be readily applied to determine the load-dependent thermal conductivity of porous adsorbents, because the local ad- and desorption inside the specimen and the thickness of the specimen are not considered. Hence, in this work a ... Mehr lesen

Melt Homogenization Improvement By Optimizing the Rotation Profile

J. Petit [1], V. Tabouret [1], B. Viana [2],
[1] ONERA, Chatillon, France
[2] IRCP/CNRS, Paris, France

During the last decades, mid-IR (3-12µm) laser sources have attracted attention due to their potential applications in different fields like infrared counter-measures (e.g: missile jamming) and remote chemical sensing. In this context, Onera has been working on the development of non ... Mehr lesen
