Aluminium has been widely used in many field of application due to the low density, sensitive to corrosion, high mechanical strength and ease of fabrication. Plating of metal on aluminium is complex and difficult because aluminium always reacts with air to form oxide. It is difficult to obtain a good adhesive property…
Two and three dimensional carbon nanotube networks (2D- and 3D-CNTNs) were prepared over silica glass substrate and in silica matrix, respectively. The aptitudes of various CNTs (single-, double- and multi-walled CNTs: SWCNTs, DWCNTs and MWCNTs, respectively) to form percolating CNTNs were compared by measurement of t…
Thermoelectric properties of the p-type (Bi,Sb) Te , hot-pressed with the (Bi,Sb) Te powders fabricated by melting/grinding method, were characterized with variation of the hot-pressing conditions. Thermoelectric characteristics of the hot-pressed (Bi,Sb) Te were also analyzed with addition of ZrO as nano inclusions.…
We report the measurement of the viscosity of pure n-dodecane and n-hexane and their binary mixtures under combined conditions of high pressure up to 200 MPa and at ambient and sub-ambient temperatures of 20oC and 5oC. Using a thermostatically controlled falling sinker-type viscometer, reproducible and reliable viscos…
L’effet de l’ozone sur la viscosite, la morphologie des fibres, le comportement au raffinage et la resistance mecanique des pâtes kraft est un sujet controverse qui anime les fabricants de pâte a papier, les fournisseurs d’ozone et les laboratoires de recherche. L’objectif de cette these est d’accroitre la connaissanc…
Nanocomposites of nanoparticles dispersed throughout a polymer matrix have been studied to great length to improve the overall polymer properties. These enhancements are observed in the thermal, physical, and/or optical characteristics. Being able to harness nanoparticles in such a way may help improve fiber technolog…
L’Echelle Internationale de Temperature (EIT-90) est materialisee par un ensemble de points fixes lies aux transitions de phases (fusion ou congelation) de metaux de hautes puretes. Ces points-fixes permettent, entre autres, d’etalonner les thermometres a resistance de platine. Ces travaux proposent une methode altern…
The dynamic modeling of the interfacial structure in two-phase flows is accomplished by using the interfacial area transport equation with various bubble interaction mechanisms as the source and sink terms. In the present study, the one-group interfacial area transport equation and two-group interfacial area transport…
du rayonnement de l'antenne réseau LWA 2D à recyclage-croisé sont améliorées.Le résultat mesuré de l'antenne réseau LWA 2D à cinq éléments donne une amélioration de 160% du niveau d'efficacité du rayonnement.Contrairement au recyclage-croisé, le deuxième concept nommé l'auto-recyclage est appliqué qu'à une seule anten…
The vibrational spectra of iron(I) porphinone, and related species were studied in this work. The iron(I) complexes were synthesized by the sodium anthracenide reduction method. The extent of reduction was monitored by UV-visible spectroscopy. The products were precipitated with heptane. Efforts to obtain single cryst…
Industry has plans for the development of an intermediate pork segment, whereby the fattening pigs will be housed on a surface area of 1.0 m2 per animal. This study analysed the economic consequences of this bigger living area. The production costs will rise by around 2 euro-cents per kg slaughter weight in a newbuild…

Resistance-capacitance delay, crosstalk, and power dissipation associated with the increasing capacitance of interconnect structures limits the performance of high-speed microelectronics and leads to the demand for porous ultralow dielectric constant (ULK) material introduction. Process integration of ULK dielectrics…
The machinery and equipment elements operating in a turbulent fluid flow, are exposed to destruction as a result of the impact of the cavitation, corrosion and abrasion processes, among which are hardest to minimize the imploding cavitation bubbles. Repeated cavitation implosions of bubbles give rise to cracks, materi…
This thesis concerns the study of Enhanced Raman Scattering phenomena, for which Surface Enhanced Raman Scattering (SERS) and Tip Enhanced Raman Scattering (TERS) experiments have been carried out. Using a variety of different techniques (silver and gold thermal evaporation, gold nanoparticle grafting on patterned sub…
Photodynamic therapy is a promising treatment for cancer. It involves the combination of a photosensitizer and light of an appropriate wavelength (laser source) to cause the destruction of cancer cells. Phthalocynanines are second–generation photosensitizers with enhanced photophysical and photochemical properties. In…
In magnetized target fusion (MTF), an imploding, conducting liner compresses a magnetized plasmoid, such as a spheromak or field-reversed configuration. The increasing magnetic field of the target reduces thermal conduction, and the liner's inertia provides transient plasma stability and confinement. Almost all of the…
La therapie photodynamique (PDT) est une methode therapeutique qui permet un ciblage specifique de lesions par irradiation lumineuse localisee de photosensibilisateurs. L’utilisation d’une excitation biphotonique pourrait accroitre son interet en augmentant sa profondeur de penetration dans les tissus et en confinant…
Nanoparticles (NPs) are ultrafine particle with lenghts in two or three dimensions > 1 nm and < 100 nm. Nanoparticles have unique properties, which make them useful for countless applications in a broad spectrum of industrial branches. However, their unique properties could present a potential hazard to the environmen…
Nous avons imagine et concu un nouveau dispositif calorimetrique, destine a caracteriser les pertes de puissance dans les composants electriques. Dans ce nouveau calorimetre, l'echange de chaleur entre le composant et la cellule de mesure s'effectue par rayonnement thermique. Ce dispositif permet de s'affranchir de la…
