Summary: This study investigated the effect of adding 1μm α-Al2O3 particles on the microstructure and mechanical properties of the AZ91E magnesium alloy. The results showed that the addition of Al2O3 improved the grain size, yield strength, ultimate tensile strength and ductility of the alloy. The refinement of the alloy secondary phases was also observed. These improvements were attributed to a combination of grain refinement and coefficient of thermal expansion mismatch between the matrix and the reinforcement particles.

Summary: The TiZrNb metal-matrix composites reinforced by in-situ formed borides were produced using different amounts of TiB2. The composites exhibited varying microstructures and mechanical properties with the increase in boride content. Load transfer strengthening was found to be the main contributor to the overall strength of the composite. The biocompatibility evaluation suggested a decrease in the proliferation rate of mesenchymal stem cells with an increase in boride content.

Summary: Two nanomicas with different particle size distributions were used to prepare transparent epoxy nanocomposites. The nanocomposites showed homogeneous dispersion and no aggregation of nanoparticles. Despite the good dispersion, no exfoliation or intercalation was observed. The nanocomposites exhibited a slight decrease in transparency and no significant change in thermal behavior. The mechanical characterization revealed an increased Young's modulus but reduced tensile strength. A peridynamics-based approach was implemented to estimate the effective Young's modulus and fracture toughness of the nanomodified materials, and the results were validated against experimental data. The mica-based composites showed high volume resistivity and could be used as insulating materials.

Summary: The key features of lead halide perovskites, including short emission lifetime and excellent luminous efficiency in the green emission region, are well-suited for underwater wireless optical communication (UWOC). However, the poor stability of perovskite nanocrystals (NCs) restricts its application underwater. This study reports extremely stable CsPbBr3 NCs in an all-inorganic amorphous glass matrix, showing high photoluminescence quantum yield and excellent stability towards water, thermal treatment, and intensive laser irradiation. The refraction index can strongly influence the lifetime values of radiative transitions in the perovskite NCs, and the large refraction index of the glass matrix enhances their radiative transition rates. Finally, the first application of perovskite NCs for UWOC shows promising results with high bandwidth and data rates.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
