In this research, Manganese aluminate (MA), Nickel aluminate (NA), and Zinc aluminate (ZA) nanocrystallites were synthesized using the combustion method at a temperature of 1173 K. This technique was selected for its effectiveness in producing nanocrystalline materials with high purity and precise compositional control. The synthesized nanocrystall...

We investigated bandgap engineering of spinel-structured MgB 2O4 (B = Al, Ga, In) alloys. The trend of bandgap change was tunable from approximated 7.8–3.6 eV by substituting group III cation atoms in MgB 2O4. To evaluate the doping possibility, we have calculated the natural band alignment and doping pinning energy of the normal and inverse spinel...
Black-to-brown Chinese ceramics have sparked the interest of material scientists since the widespread discovery of complex dendritic structures containing mainly the rare ɛ-Fe 2 O 3 polymorph in their glazes. This study proposes to tackle this issue using two electron diffraction mapping techniques, transmission Kikuchi diffraction and automated cr...

Pink spinel anorthosite (PSA) and pink spinel troctolite (PST) are two lunar lithologies known to contain Mg-rich spinel. PSA rich in spinel and lacking mafic minerals, was detected by the visible and near-infrared reflectance spectroscopy. PST clasts were found in returned lunar samples and meteorites. NWA 13191 is a recently approved lunar meteor...
L’opération réalisée en 2021 entre les numéros 220 et 251 et à l’angle de la rue de Saint-Didier à Briord (Ain, 01) en amont du projet d’aménagement d’une maison individuelle a permis de documenter l’évolution d’un secteur de l’agglomération antique de Briord en rive droite du Rhône. La surface de l’assiette du projet, d’environ 2070 m2, se situe n...

Microwave dielectric ceramic (MWDC) is crucial in advancing the development of 5G technology and the communication field. The prediction or calculation of its properties is of great significance for accelerating the design and development of MWDCs. Therefore, the prediction of permittivity of spinel MWDCs based on machine learning was investigated ...
The surging adoption of lithium-ion batteries, driven by diverse applications including electric vehicles, renewable energy storage, and portable electronics, has intensified the demand for high-energy cathode materials. The existing methods to produce cathode materials typically include high-temperature (>800 °C) sintering for a long period of tim...

To understand the effect of refractories in the ladle lining system on the evolution of inclusions in the secondary refining process, refractory samples were taken from different locations in the ladle system (Slag lining bricks, Sidewall bricks, Refractory mortar, and Bottom bricks). Laboratory experiments were carried out using heavy-rail steel s...

High-entropy thin films of Mn0.6Co0.6Ni0.6Mg0.6Cu0.6O4, Mn0.6Co0.6Ni0.6Mg0.6 Zn0.6O4, and Mn0.6Co0.6Ni0.6Cu0.6Zn0.6O4 (MCNMC, MCNMZ, and MCNCZ) with equiatomic proportions were synthesized using chemical solution deposition on silicon substrates. Structural analysis confirmed a consistent face-centered cubic spinel structure, while significant diff...
