Ion-selective membranes can be used in lab-on-a-chip devices for various portable applications in this field. These devices can be used as concentrators for analytical chemistry and for micro-scale filtration. Here, a binary aqueous electrolyte solution in a microchannel has a potential bias applied across it and it is driven through an ion-selective membrane. Ion concentration gradients form ...

The purpose of this paper is to present a numerical modeling of plasma phenomena in beryllium emissions using COMSOL Multiphysics software. The Beryllium films were deposited on mirror polished fine grain graphite substrates using the Thermionic Vacuum Arc (TVA) technology available at NILPRP – Magurele, Romania. The developed system for thin film deposition using thermionic vacuum arc (TVA) ...

Erodible polymeric scaffolds can mitigate long-term risks associated with permanent implants currently used to treat ischemic artery disease. However, safe deployment of erodible scaffolds is predicated on understanding the interactions between evolved material by-products and local biological tissues. We developed an integrated computational model of polymeric scaffold degradation, by ...

We treat a gradient constrained minimization problem which has applications in mechanics and superconductivity. A particular case of this problem is the elastoplastic torsion problem. In order to solve the problem we developed an algorithm in an infinite dimensional space framework using the concept of the generalized Newton derivative. The Desktop environment of COMSOL Multiphysics 4.1 was ...

Evanescent-wave optical waveguide is widely used as sensing platform for chemical/biological sensor applications. Our research group contributed to on-chip IR sensor technology and made recent progress in miniaturizing such devices utilizing quantum cascade lasers (QCL) in combination with planar GaAs/Al0.2Ga0.8As waveguides. Furthermore progress is reported toward microfabricated Mid-infrared ...

For the educational program of Fluid Dynamics at the Fontys Hogeshool of Applied Physics, a wind tunnel was developed for tests of flow profiles of objects, such as a ball, cube or plate. Students are expected to measure the air resistance of a variety of objects, and verify the measurements with the turbulent CFD module of COMSOL. The measurements and the COMSOL simulations match nicely, and ...

The actuator comprises of a temperature sensitive composite deflecting beam, a piezoelectric substrate and a field effect transistor. The temperature rise causes an expansion in the composite beam thereby causing it to deflect. The deflecting beam impinges on the piezoelectric crystal and generating voltage. Response curves for the deflection versus temperature for temperature ranges ...

Monitoring of indoor CO2 concentration is of particular interest to detect room occupancy in order to optimize power consumptions of building. One approach to monitor the indoor CO2 concentration is to use optical detection using specific absorption lines of CO2 molecules in the infrared domain close to 4.2 µm. Such optical sensors include a detector, typically a micro-bolometer, an IR source ...
