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 […]

Biodiesel refers to a vegetable oil or animal fat based diesel fuel consisting of saturated and unsaturated long-chain alkyl esters. Low value biodiesel has been developed on a commercial scale, however the application is limited. The conversion of biodiesel to high value C8-16 n-alkanes currently uses metal catalysts (Pt/C), which is an expensive technique. Designing […]

The alkylation of benzene is receiving increased attention in petrochemical industry. This is because it is potentially an alternative to produce xylene (used in production of polyester and plastic water bottles) from coal and natural gas. It is expected that changing the acidity of the reaction catalyst would improve the utilization of methanol in the […]

Ce projet concerne de la formation et le deplacement de nanoparticules de Carbone dans des plasmas basse pression aves presence d’un champ magnetique. On appelle communement ces milieux plasmas poussiereux. Nous travaillerons sur les mecanismes physico-chimiques permettant de generer des nanoparticules dans le volume du plasma et depuis les parois du reacteur. Nous porterons une […]
