TiC-TiSiC gradient hybrid interphase on the surface of SiC fibers was successfully obtained through the molten salt method. The electromagnetic parameters of the prepared samples can be accurately controlled by adjusting the reaction temperature. A significant bimodal effect is observed in electromagnetic parameters patterns, corresponding to the double interface layer. TiC-TiSiC gradient hybrid interphase plays a dominant role in impedance matching, as well as in the attenuation layer through multi-interfacial polarization and conduction loss. Through the co-evaluation of the suppression of specular reflection and non-specular scattering properties of the samples, the SiC fiber with the TiC-TiSiC gradient hybrid interphase is expected to be a high temperature resistant radar absorbing material for future stealth aircraft.

The Ichkeul-Bizerte Lagoon Complex (IBLC), a critical ecosystem for local biodiversity, faces a pressing threat due to climate change and severe pollution. Despite past conservation efforts, pollution persists, particularly in the Bizerte Lagoon. This study investigated the impact of water dynamics and climatic conditions on heavy metal contamination in the IBLC's sediments.

Objective: Many cancer survivors may experience irreversible infertility due to chemotherapy treatment for childhood cancer. In this study, spermatogenesis development was evaluated following the grafting of fresh and frozen-thawed testicular tissue from neonatal mice to the epididymal fat of adult mice.
Methods: After bilateral castration of recipient mice, fresh or frozen-thawed neonatal testis tissues were grafted into the epididymal fat of the mice.

This computational study investigated the catalytic efficiency of novel RhCp complexes (X = CF, SiF, CCl, SOH) in [3 + 2] azide-alkyne cycloaddition reactions density functional theory (MN12-L/Def2-SVP). Through quantum mechanical approaches, we explore the impact of different substituents on the Cp* ligand on the mechanism, selectivity, and reactivity of these Rh-based catalysts. Non-covalent interaction (NCI) and reduced density gradient (RDG) analyses, along with frontier molecular orbital (FMO) and Hirshfeld atomic charge analyses, were utilized to assess ligand stability and catalytic performance.

Senescent cells are involved in age-related disorders in different organs and are therapeutic targets for fibrotic and chronic pathologies. Immune-modulating agents, able to enhance senescent cell detection and elimination by endogenous immune cells, have emerged as pharmacological strategies. We report herein a nanoparticle for immune cell-mediated senolytic therapy designed to recruit immune cells in response to specific enzymatic matrix metalloproteinase-3 (MMP-3) activity in the senescence-associated secretory phenotype.

Purpose: The study's purpose was to use a simple geometry phantom to validate the deformable image registration (DIR) accuracy and dose warping accuracy in carbon ion radiotherapy (CIRT) and to provide an index for dosimetry in CIRT.
Materials And Methods: We used geometric and anatomical phantoms provided by AAPM TG-132. The DIRs of 3 different settings were performed between reference and translational images for each phantom.
