1Institute of Physics, Polish Academy of Sciences, al. Lotnikow 32/46, 02-668 Warsaw, Poland

The monocrystalline semiconductor nanowires (NWs) attract great interest as they reveal new properties that differs from the ones of the bulk equivalents. In addition to small size (10-100 nm diameter), one of their advantages is extremely high surface to volume ratio. This determines ... Read More

Modelling Ion Production inside an Electron Impact Ionizer for High-Vacuum Gas Analysis

1TNO NanoInstrumentation, Delft, The Netherlands
2TNO, Delft, The Netherlands

Residual Gas Analyzers (RGA) are often used to measure background gases and contaminations in vacuum systems. An ionizer is used to ionize gas molecules and these ions are accelerated and focused by an electrical field from the ion source to form an ion beam. The ions can be ... Read More

Understanding the increased performance of novel interconnected-channel monolithic reactors

P. López1, F. García, A. Quintanilla, J.A. Casas1
1Universidad Autónoma de Madrid, Madrid, Spain

The versatility of the 3D printing technology has allowed developing originally structured catalysts for interesting reactions, for instance, the 0.5wt.%Fe/SiC monoliths for the treatment of industrial wastewater. These monolithic structures, manufactured by Robocasting, have ... Read More

3Department of Energy, Environmental and Chemical Engineering, Washington University in St. Louis, St. Louis, MO 63130, USA

Industrial catalytic processes require tailored catalysts with an optimized performance to reduce energy consumption and waste products. Besides an optimum temperature, pressure, and composition, the distribution of active material can be seen as a valuable additional design variable. ... Read More

Simulation of Laser-Induced Forward Transfer of High-Viscosity pastes

Juan José Moreno Labella1, Miguel Morales1, D. Munoz-Martin1, C. Molpeceres1

1Centro Láser, Universidad Politécnica de Madrid, Spain

Laser-Induced Forward Transfer (LIFT) is a direct-write technique for transferring small volumes (even picolitres) of material through laser irradiation. The characteristics of this material can be in a wide range of viscosities and can respond to different rheological behaviors, from ... Read More

Particle Steering in Magnetic Drug Targeting: A Simple Comsol Model
