Manganese is an important industrial metal used as an additive for production of various steels, non-ferrous alloys, electronic components and special chemicals. In order to get high purity (99.999%) manganese for advanced applications the electrorefining of manganese will be investigated. Electrorefining will be studied in an ammonium halide salt solution to minimize contamination of the […]

Irdeto has a need to create software that is protected in the white-box attack context, which means that attackers have direct access to the software, can execute it, modify it, and stop it to read the data being processed by the software. If attackers are able to modify software in ways that are useful to […]

Researchers from academia and industry have recently shown interest in generating electricity from the kinetic energy of the water streams. Generating electricity using hydrokinetic turbines is an emerging technology and its development depends on the good understanding of the different aspects of the technology. In this project we measure and analyze the flow velocity and […]

En présence de conditions atmosphériques spécifiques, de la glace peut se former sur les surfaces critiques d’un avion. Cette accumulation de glace nuit considérablement à la manoeuvrabilité et à la sécurité de celui-ci. Une telle situation peut même mener à la perte de contrôle et possiblement l’écrasement de l’aéronef. Le projet proposé vise à améliorer […]

Non-metallic technologies, including composite materials, have the potential to improve aircraft engines performances and fuel efficiency, and therefore gained a lot of popularity in the aerospace sector in the past decades. Therefore, the overall objective of this research project is to develop an understanding of all available non-metallic technologies, their maturity and value proposition when […]

The proposed summer exchange program is to perform experimental study of droplet generation and mixing droplets in droplet-based microreactors. The droplets are generated by feeding substrate into a tube and letting the substrate form drops from the other side of the tube. Each individual droplet acts as a small reactor under confined conditions. Accordingly, the […]

L’holographie acoustique en champ proche (Nearfield Acoustical Holography – NAH) est une technique d’imagerie acoustique permettant de visualiser un champ sonore dans l’espace tridimensionnel. Son fonctionnement repose sur l’acquisition du champ de pression acoustique à l’aide d’une matrice de microphones située dans le champ proche de la source. Le signal obtenu fait office de condition […]

Magnesium chloride (MgCI 2) is a commercial catalyst important for the production of polyolefin material. Although magnesium chloride has been used for over 50 years, the active site is still not entirely known. This research aims to learn more about the active site. The formation of defective magnesium chloride surfaces acts with Ziegler-Natta catalysts and […]

Ethanol has gained much attention as a potential fuel alternative or additive due to its environmental and long-term economic advantages. Recently, a method for synthesis of ethanol from syngas has been proposed. The purpose of this research is to explore the effects of Cu on the synthesis process, in order to find the most efficient […]

C2+ oxygenates synthesis directly from syngas is one of the most promising processes for utilizing non-oil fossil fuels cleanly and efficiently. Through previous experiments, it has been found that the reaction rates and selectivity of C2+ oxygenates increases remarkably with the addition of MnOx. However, the detailed mechanism for the promotional effect of MnOx on […]

Cavitation bubble can be generated by ultrasound, laser or spark discharge underwater. It has good potential in the application of medical treatment, environmental treatment and surface cleaning. When the bubble collapse, the vapor inside will be compressed quickly and the temperature will rise to several thousand Kelvin, even reach ten of thousand Kelvin, and the […]

This project aims at designing a high-efficiency DC-DC converter for TFT touch sensors. The main task of the converter is to step-up the low and variable input voltage to a higher and more stable voltage that is able to power the touch sensor. The most challenging part of the design is the regulation of the […]
