FEM modeling of highly strained monocrystalline ZnTe/CdTe core-shell hetero-nanowires

Serhii Kryvyi1, Slawomir Kret1, Dorota Janaszko1, Jakub Plachta1, Piotr Wojnar1
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

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

ENGINEERING INTERCONNECTED-CHANNEL MONOLITHIC REACTORS: FROM COMSOL TO 3D PRINTING

F. García-Missana1, G. Vega1, A. Quintanilla1, J.A. Casas1
1Chemical Engineering Department, Universidad Autónoma de Madrid, Spain

Three-dimensional (3D) printed 0.52 wt.% Fe/SiC monoliths with interconnected channels, fabricated by direct ink printing or Robocasting, are feasible and robust catalysts for the hydroxylation of phenol to dihydroxybenzenes using hydrogen peroxide as oxidant in aqueous media [1]. ... Read More

Shadowing Effects of Monofunctional Catalysts in TAP Reactors

B. Denis1, D. Constales1, V. Galvita2, G.S. Yablonsky3

2Laboratory of Chemical Technology, Ghent University, Ghent, Belgium
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

A. Thalmayer1, S. Zeising1, D. Ahmed1, G. Fischer1, J. Kirchner1
1Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), Germany

Magnetic nanoparticles offer numerous applications in medical diagnosis and therapy. One example of a possible application is the so-called Magnetic Drug Targeting (MDT), which is a therapeutic approach in cancer therapy. Thereby, the cancer drug is bounded to magnetic nanoparticles, ... Read More

Corrosion marks were found in specific areas on the outer wall of a process container. The container is cooled by a spiral cooling jacket. The corrosion marks were found in the lower and upper circumference of the container and also in the areas adjacent to the water inlet and outlet. ... Read More

Static Magnetic Localization of Capsule Endoscopes: A Differential Method

S. Zeising1, K. Ararat1, A. Thalmayer1, G. Fischer1, J. Kirchner1
1Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), Germany

Wireless capsule endoscopy (WCE) is a less invasive alternative to conventional endoscopy. In WCE, a patient swallows a small capsule equipped with a camera, allowing a video of the gastrointestinal tract (GIT) to be captured for diagnostic analysis. To ensure an accurate diagnosis and ...
