    Compositionally Disordered Doped with Cerium Crystalline Garnet Type Materials for Brighter and Faster Scintillations by M. V. Korzhik

    Published 2021-12-01
    “…Ce-doped tetracationic garnets (Gd, M)3Al2Ga3O12(M = Y, Lu) form a family of new multipurpose promising scintillation materials. The aim of this work was to evaluate the scintillation yield in the materials of quaternary garnets activated by cerium ions with partial isovalent substitution of the matrix-forming gadolinium ions by yttrium or lutetium ions.Materials were obtained in the form of polycrystalline ceramic samples, and the best results were shown by samples obtained from the raw materials produced by the coprecipitation method. …”

    Acoustic topology optimization using a mixed formulation and a three-material scheme by B. Ferrándiz, F.D. Denia, J. Martínez-Casas, E. Nadal, J.J. Ródenas

    Published 2025-03-01
    “…In this work, this formulation is applied only to a localized design subdomain to balance its high computational cost, while the remaining acoustic domain uses a conventional pressure-based approach. A three-material interpolation scheme is introduced to optimize designs with air, solid, and porous materials, and is applied to three case studies. …”

    Destabilization of Immersed Dense Granular Material Submitted to Localized Fluidization: An Experimental and Numerical Study by Aboubacar Sidiki Dramé, Li Wang, Yanping Zhang

    Published 2021-01-01
    “…An alternative experimental approach and a numerical analysis for the study of destabilization by localized fluidization of an immersed dense granular material are presented. To visualize the evolutions of the internal structure of the granular medium, the hydrogel beads, composed of about 99% of water and having substantially the same refraction indexes, are used as solid phase. …”
