Summary: AA7017 + x vol. % Al2O3 (x = 5, 10, 20) nanocomposite powders were synthesized by HEBM process, and the powders milled for 20 hours showed better performance. The synthesized powders were characterized using XRD, HR-SEM, HR-TEM, Zeta particle size analyzer, and TG-DSC. The particle sizes obtained from different diffraction analysis models were compared with the results from PSA, HR-SEM, and HR-TEM analyses.

Summary: In this study, ZnGa2O4 nanocomposites were synthesized via a hydrothermal method and used for the photocatalytic degradation of organic dyes under UV irradiation. The structure, morphology, size, and optical properties of ZnGa2O4 were characterized using various techniques, and the degradation process followed second-order kinetics. The results demonstrated high efficiency in degrading industrial dyes, suggesting potential for more efficient ZnGa2O4 nanocomposites for photocatalytic applications.

Summary: In this study, different weight percentages of amine-functionalized nano-alumina (F-Al) were added into diglycidyl ethers of bisphenol-A (DGEBA) epoxy resin and areca fiber (AF) composite. The F-Al acted as an adhesion promoter and improved the thermal, mechanical, and thermo-mechanical properties of DGEBA/AF nano-composites.

Summary: The study found that a Si modified steel SIMP exhibited better oxidation resistance compared to T91 in 500 degrees C steam with a flow rate of 5 m/s, and the oxidation rate was significantly enhanced at relatively low dissolved oxygen levels. This suggested that not only alloy composition and dissolved oxygen, but also the flow rate, played important roles in the corrosion behavior of ferritic-martensitic steels.

Summary: The technical potential of WCu alloys is limited by the modest fracture characteristics of the material system in its coarse-grained condition. To address this, a W-50 at.% Cu composite with a nanocrystalline microstructure was processed using high-pressure torsion deformation. The resulting microstructures were quantified, and the mechanical properties were investigated. The study found that the processed specimens had smaller grain sizes and increased amount of mechanically intermixed W in the Cu grains. The mechanical properties of the processed specimens were comparable to those of the coarse-grained specimens.

Summary: The corrosion resistance of the TiB2-12(Fe-Co-Cr-Ni) cermets can be improved by reducing the size of TiB2 powder, increasing the proportion of Fe-Co-Cr-Ni solid solution, and controlling the porosity of the cermet and the precipitation of secondary borides. The corrosion kinetics exhibits a linear relation with the immersion time.

Summary: The structure and properties of TGDDM/F-Al nanocomposites were studied by adding various weight fractions of F-Al reinforcement in TGDDM epoxy. The results showed that the addition of 1 wt% F-Al significantly improved the mechanical properties of TGDDM epoxy nanocomposites and increased both Tg and IDT.

Summary: This study investigates the fabrication and characterization of Cu-Ti-B alloys through ball milling of Cu, Ti, and B powders, focusing on the in situ formation of TiB2 and its impact on the mechanical properties of the composites. The results indicate that the in situ formation of TiB2 particles plays a crucial role in determining the mechanical properties of the alloys, which improve with increasing Ti and B content.

Summary: The effect of nanoclay on the mechanical properties of E-glass/epoxy composites was investigated. It was found that the shear strength, tensile strength, and modulus of elasticity in the fiber direction, as well as the tensile strength in the transverse direction, decreased for all ratios. However, the Poisson's ratio increased at the ratios of 3 and 5 wt%, while the modulus of elasticity in the transverse direction increased at the ratio of 1 wt%. Additionally, the flexural strength and interlaminar shear strength increased at the ratio of 1 wt%.

Summary: This study focuses on the synthesis of Dy3+ doped Potassium Strontium Vanadate (KSrVO4) nanopowders and investigates their structural, spectroscopic, optical, and morphological characteristics. The results show that the nanophosphors have a small crystallite size, consistent functional groups, and particle size. Under UV light excitation, three major peaks were observed. Furthermore, the nanophosphors exhibited suitable CCT, enhanced color purity, and high quantum yield, suggesting potential applications in w-LED devices.
