The anisotropy of magnetic emulsions induced by simultaneously acting electric and magnetic fields is theoretically and experimentally investigated. Due to the anisotropy, the electric conductivity and magnetic permeability of a magnetic emulsion are no longer scalar coefficients, but are tensors. The electric conduct…
It is well known that the long-time storage of PADC track detectors in vacuum significantly decreases the track registration sensitivity. In order to identify the chemical modification along ion tracks in PADC, we have made a series of FT-IR measurements for thin PADC films irradiated by proton and heavy ions in air.…
Etude de faisabilité d'un dispositif photovoltaïque à porteurs chauds La cellule photovoltaïque à porteurs chauds se caractérise par une population électronique hors équilibre thermique avec le réseau, ce qui se traduit par une température électronique supérieure à la température du matériau. Il devient alors possible…

Ziel dieser Diplomarbeit war es, eine vergleichende Betrachtung, zwischen einem bisher in der Textilproduktion verwendeten Vorbehandlungsprozess und dessen Optimierung, unter Einsatz neuer Prozesschemikalien und neuer Prozessparameter, durchzuführen. Die ursprüngliche und die optimierte Rezeptur werden anhand der Erge…
In this work we perform a theoretical study about fluorine adsorption in BC2N nanostructures. The fluorine interaction with the BC2N nanostructures was studied using only atomic fluorine on two nanotubos with different chiralities (zigzag(5,0) and armchair(3,3)) and a monolayer. We used first principles calculations b…

WB6101. Materiaalkunde 1 voor Werktuigbouwkunde. Leerdoelen: 1. Op basis van eigenschappen en gedrag onder externe invloeden een klassificatie te maken van materialen en op basis daarvan een eerste indruk te krijgen van hun geschiktheid in bepaalde toepassingen. 2. Inzicht te verkrijgen in de rol van materialen, mater…
In this paper we study the asymptotic behavior of a structure made of curved rods of thickness 2δwhen δrightarrow 0. This study is carried on within the frame of linear elasticity by using the unfolding method. It is based on several decompositions of the structure displacements and on the passing to the limit in fixe…

Fossil fuel is depleting rapidly due to its limited reserve and increasing demands from various industry. The corresponding issue, which causes environmental degradation as well as political and economic concern, has encouraged the needs of searching for alternative fuel. One of the solution is the biodiesel which is…
We present fatigue experiments performed on filled natural rubber and study the correlations between crack growth dynamics and fracture morphologies imprinted by an irregular crack path.Slow crack growth dynamics is obtained by cyclic fatigue in a pure shear test.We will show that an unstable crack growth regime exist…
Natural rubber (NR), cis-1,4-polyisoprene, has remarkable mechanical properties which are generally explained by strain-induced crystallization (SIC). SIC is commonly investigated by wide-angle X-ray diffraction (WAXD) (see Murakami et al. 2002, Toki et al. 2003, Trabelsi et al. 2003a, among others, for a more complet…
Thermoplastic elastomers (TPEs) form a class of soft polymeric material of great practical interest. They typically show the high elongations to break and low stiffnesses associated with natural and synthetic rubbery materials, and hence are of value in a wide range of products where flexibility and resilience are req…
A novel underwater strategy was developed at the INL as an interim action to reduce the hazards associated with maintaining excess SFPs containing water, sludge and other debris. It is estimated that hundreds of these facilities exist around the world. They present a hazard to the environment in that they often leak a…
In the article the results of research of selective detoxications properties of method of continius hemofiltration are resulted in treatment of sharp thallium intoxication. The concentrations of thallium are investigational in the whey of blood during procedure of hemofiltration. Conclusions are done in relation to po…
This work has been carried out in the frame of a French national research program on new refractories for glass production (NOREV) and focussed on the numerical simulation of the post-casting cooling of fused-cast refractories with a very high zirconia content (HZ). A numerical model of the cooling-down sequence of a…
