Jet Electrochemical Machining (Jet-ECM) is an unconventional procedure using localized anodic dissolution for micromachining. An increasing of the electrolyte temperature will lead to an increase of the electrical conductivity of the electrolyte by about 30% and to a reduction of the ... En savoir plus
The technique of magnetic drug targeting binds genetic material or drugs to superparamagnetic nanoparticles and accumulates them via an external magnetic field in a target region. However, it is still a challenge for this approach to succeed in areas with high flow rates, like the aorta ... En savoir plus
Prof. Jeng-Shian Chang received his B.Ec. degree (1974) in Mechanical Engineering from National Taiwan University, Taipei, Taiwan, and M.Sc. degree (1981) in Mechanical Engineering and M.Sc. degree (1983) in Computer Science both from Syracuse University, USA. In 1984 he received the Ph ... En savoir plus
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 ... En savoir plus
In this study, a new thermoelectric harvester with fluid flow for increased performance is introduced. The thermoelectric generator is 3D vertical configuration with p- and n-doped Silicon thermolegs. There is water flow between channels integrated through the thermoelectric columns, ...

The aim of the study is to predict the formation of porosities in the case of spot laser welding of tantalum. During the interaction, a deep and narrow cavity, called the keyhole, is generated. At the end of the interaction, surface tension provokes the collapse of the keyhole. Gas ... En savoir plus
In this paper, the mechanism of charging process was simulated and analyzed. The simulation was conducted using COMSOL Multiphysics® software, based on the laminar two-phase flow level-set interface coupling with the electrostatic interface. Meanwhile, different parameters (such as the ... En savoir plus
Different facilities for hadrontherapy have been built in the recent past. AISHa ion source has been designed by keeping in mind the typical requirements of hospital-based facilities, where the minimization of the mean time between failures (MTBF) is a key point together with the ... En savoir plus
We use finite elements simulations in order to study the fluid flow behavior in a chamber of a preconcentrator. We realized that most part of the fluid does not affect our preconcentrator because it is going out the chamber at high distance above it and parallel to the preconcentrator. ... En savoir plus
The developments of microsystems for biotechnology have been fast in the last few years, and no sign of slowing down is observed. It has begun with lab-on-chip for genomics, especially for the recognition of DNA sequences, followed by protein reactors and immunoassays, and today the ... En savoir plus
