Le débat entre la théorie et la pratique dans l'enseignement sur l'importance de chacun comme base de la formation en Master existe depuis plusieurs années. Ce lien est souvent sous-évaluée et on a tendance à oublier que de la théorie naît la pratique et que la pratique est basée sur la théorie. A l'université Polytechnique des Hauts-de-France, dan...

La structuration progressive des activités industrielles à l’échelle mondiale a entraîné dans son sillage une construction de filières de recyclage des matériaux basées sur un retour à l’état de matière pouvant être directement réintroduite dans des chaînes techniques de production standardisées. Cette standardisation garantissant ainsi des objecti...

The influence of the chromia volatilization on the oxidation kinetics of Inconel 625 was investigated at 900 ◦C under flowing wet air (74%N2-18.5%O2-7.5%H2O) through an interdisciplinary approach, coupling experiments and gas phase simulation. Oxidation tests showed a strong decrease in the volatilization rate of lined-up samples from the inlet to ...

During the 20th century, polymers developed at a very high speed, due to their ease of production and their versatility, allowing the development of different classes of materials depending on the intended application. Due to their popularity, the production of polymers has resulted in a huge amount of waste. In particular, vulcanized elastomers ha...

Agricultural soils are exposed to multiple contaminants through the use of agrochemicals or sewage sludge, introducing metals, nanomaterials and others. Among nanomaterials, carbon nanotubes (CNTs) are known for their large surface area and adsorption capabilities, possibly modifying other element behavior. However, to date, very little is known ab...

β-FeSi2 is a promising material for thermoelectric application, especially if it can be nanostructured to decrease the lattice contribution to the thermal conductivity. It can be even more interesting if the entire chain of processes implemented to obtain it is not too time and energy consuming. In this paper we report a simple route to synthesize ...

The chemical vapor deposition of carbon is performed onto a commercial yttria-stabilized zirconia (3YSZ) powder bed. This produces few-layered-graphene (FLG) film uniformly covering the 3YSZ grains, without the manipulation of any pre-existing nanocarbon in the form of graphene platelets. The powders are then consolidated by spark plasma sintering,...

The goal of this study is to investigate the mechanical and elastic characteristics of the Mn15Si26 compound via experimental nanoindentation measurements and ab-initio calculations. The mechanical properties such as Young’s modulus (E) and nanohardness are important inputs for improving the design and mechanical reliability of thermoelectric modul...

Micrometer to millimeter platelets-like single crystals of the 2D-derivated perovskite structure Cs2PbCl2I2 were synthesized by a very simple route using the humid ambient environment surrounding a DMSO solution containing the salt precursors. Cs2Pb1-xMxCl2I2 formation was also evidenced by single crystal X-ray diffraction, with M = Bi, Ga, In and ...
