The convergence of nanotechnology and biotechnology has led to substantial advancements in nano-biomaterials (NBMs) used medical devices (MD) advanced therapy medicinal products (ATMP). However, there are concerns that applications NBMs for diagnostics, therapeutics regenerative medicine could also pose health and/or environmental risks since the current understanding their safety is incomplete. A scientific strategy therefore needed assess all emerging along life cycles these products. To...
Les auteurs ont etudie l'interdiffusion dans les systemes binaires : Ti-Nb, Zr-Nb, V-Nb, Mo-Nb, W-Nb. La methode experimentale est fondee sur l'analyse a la microsonde de couples differentiels Nb-Alliage, et metaux purs. A temperature donnee, Matano permet le calcul variations des coefficients d'interdiffusion avec composition, Hall, d'heterodiffusion. Pour chaque impurete, coefficient d'heterodiffusion varie suivant une loi d'Arrhenius. theories classiques ne permettent pas d'expliquer tres...
This work deals with the study of ignition and explosion characteristics nanoparticles. It has been carried out on various powders: zinc, aluminum, carbon blacks... Specific behaviours have highlighted during first phase this project (Nanosafe 2). For instance, it demonstrated that there mainly exists two combustion regimes are either kinetically controlled, for small size particles, or diffusion large particles (generally diameters greater than 1 2 μm). found as particle decreases, minimum...
The ionization distribution in depth has been determined experimentally for two elements, lead and titanium, at various incident electron energies, by the sandwich tracer technique previously used Castaing Descamps.
2014 L'aluminiure de niobium NbAl3 est le constituant principal des couches protec- trices à base d'aluminiures alliages niobium.L'oxydation ce composé a été étudiée dans domaine températures 600-1 400 °C.Au-dessus 1 100 °C, l'oxydation contrôlée par un mécanisme diffusionnel avec formation deux couches, une couche interne Nb2Al, externe d'alumine NbAl3/Nb2Al/Al2O3 .Au-dessous 1100 d'oxydation beaucoup plus complexe.En outre, parallèlement l'oxydation, au-dessous 200 il se produit...
