L’objectif de cette étude est de comprendre le comportement sous irradiation de la phase MAX Cr2AlC, dont les propriétés mécaniques et la résistance à l’oxydation permettent d’envisager des applications dans les réacteurs nucléaires. Pour cela, des films minces polycristallins et des monocristaux de Cr2AlC ont été implantés avec des ions He+. L’inf...

Multicomponent Co25Fe25Mn5Ni25Ti20 eutectic high entropy alloy (EHEA), synthesized by vacuum arc melting followed by suction casting method resulted in two types of solid solution phases (fcc CoFeNi-rich (α) and bcc Ti-rich (β)) and Ti2(Ni, Co) type Laves phase. The hot deformation behaviours have been investigated at a temperature ranging from 107...

Au cours des dernières années, les cellules solaires à base de pérovskites hybrides ont attiré considérablement l’attention. Dès lors, grâce aux travaux de recherche intensifs déployés, les efficacités de ces cellules ont très rapidement évolué pour atteindre récemment un record de 25,2 %. Le caractère hybride (organique et inorganique) confère à c...

La méthode d’élaboration de poudre par flash combustion permet l’obtention de poudres de taille nanométrique. Des quatre combustibles testés, ceux semblant mener le plus facilement à la formation de la phase recherchée (CaZrO3) sont la glycine et la ß-alanine. Ils conduisent à des poudres cristallisées après synthèse ainsi qu’à des éramiques relati...

In this study, the reduction-carbonization property of WO3 obtained by thermal decomposition of ammonium paratungstate (APT) under N-2 and air atmosphere in a fluidized bed was investigated. The decomposition property of APT in N-2 and air was analyzed by TG analyzer. Phase, morphology, deoxidation rate and carbonization rate of the decomposed prod...

X-ray diffraction (XRD), Scanning Electron Microscope-Energy Dispersive Spectroscopy (SEM-EDS), and Fourier Transform Infrared Spectroscopy (FT-IR), were applied to analyze the organic matrix of two Molluscan shells. The Mollusca shells are mineral structure and calcium carbonate crystallized as aragonite. The FT-IR spectra showed Alkyl Halide, Alk...

Crystalline phase is the key factor for catalyst activity. The zirconium modified PCs/gamma-Al2O3 samples were prepared through a simple step incipient-wetness impregnation method. The raw materials and samples were characterized by thermogravimetric-differential analysis (TG-DTA), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (F...

Dissimilar Al-Cu joining is an emerging area of interest for both academic and industrial research. Friction stir welding being a novel solid-state joining process can overcome a number of issues raised by fusion welding of such dissimilar joint and thus good joint strength is expected. However, understanding the material flow and simultaneously th...

Ethyl acrylate (EA) is synthesized by ethyl acetate (EtOAc) with formaldehyde (FA) through aldol condensation with fixed-bed reactor, and a series of Ce-P-Cs/gamma-Al2O3 catalyst was developed. The catalysts were characterized with XRD, XPS, SEM-EDS, NH3- and CO2-TPD, BET, and pyridine FTIR. The influence of acidity and basicity on activity was dis...
