Summary: Using thermally activated chemical vapor deposition (CVD), Ti1-xAlxN coatings with Al contents up to x > 0.8 can be synthesized due to their high global Al content and self organized nanolamellar microstructure. However, the formation mechanism of the microstructure and the resulting coating properties are not fully understood. The study investigates the effects of deposition temperature, pressure, and gas feed rotation speed on the microstructure and mechanical properties.

Summary: This paper presents the interfacial, tensile, and bending properties of a novel wide-angle woven fabric/ethylene propylene diene monomer (EPDM) composites. The results show that the wide-angle fabric/EPDM composites have higher tensile strength and modulus compared to the orthogonal fabric/EPDM composites. The bending strength of the two composites is similar, but the bending modulus of the wide-angle fabric/EPDM composites is significantly higher.

Summary: The investigation focused on the synthesis of nanocomposite polymers reinforced with TiO2 and SiO2 nanoparticles at different concentrations. The interaction between the nanoparticles and the polymer matrix resulted in improved mechanical properties with low weight concentrations. The crystalline and morphological properties of the nanoparticles were characterized, and the molecular structure of the coatings was analyzed. The crosslinking efficiency, hydrophobicity, and adhesion of the nanocomposites were evaluated, and mechanical tests showed significant increases in hardness, elastic modulus, and tensile strength with increasing nanoparticle concentration while maintaining ductility.

Summary: The creep behavior of poly(ether-ketone) (PEK)/MWCNT nanocomposites prepared by solution method and hot pressing was studied for the first time. The addition of MWCNT significantly increased the hardness, storage modulus, and glass transition temperature of PEK. The dispersion of MWCNT in the matrix affected the reinforcing efficiency of the nanocomposites, with lower loading of MWCNT showing better performance at higher temperatures. The creep strain and unrecovered strain of the nanocomposite decreased with the incorporation of 2.07 vol% MWCNT, but increased with further addition of MWCNT.

Summary: In this study, Ti3SiC2/Al2O3 composites were prepared using Ge as a sintering aid, which improved the purity and mechanical properties of the composites. The optimal amount of Ge was found to be 0.3 mol, resulting in composites with high flexural strength, fracture toughness, and microhardness. The formation of Ti-3(Si1-xGex)C-2 was confirmed through various analyses, and a model crystal structure was established with the calculated solid solubility of Ge.

Summary: The effect of deposition temperature on the structural and nanomechanical properties of Mg doped hydroxyapatite (HAP) was studied. By adding Mg into the HAP matrix, the hardness and elastic modulus values of the coatings were significantly improved. XRD analysis revealed the presence of HAP and Mg in the coated samples. Increasing the deposition temperature improved the electrochemical behavior of the coatings. Additionally, by increasing the deposition temperature and incorporating Mg into the HAP matrix, the hardness and elastic modulus were increased by more than two-fold.

Summary: The presence of oxides generated during coal combustion affects the ash fusion temperature (AFT). Coals from Meghalaya, particularly those with higher amounts of acidic components and lower amounts of basic components, have lower slagging and fouling indices and increased AFT. Statistical analysis confirms the influence of various fluxing agents on the AFT of the coal samples.

Summary: Bio-nanocomposite films of sodium alginate/polyvinyl alcohol (SA/PVA) blend with boehmite alumina (BA) nanoparticles were developed in this study. The films exhibited high transparency and eco-friendliness. The BA nanoparticles showed a homogeneous dispersion at low loading but agglomerated at high loading. The addition of 3 wt% BA nanoparticles improved the mechanical properties and hydrophobicity of the films. The films also demonstrated good thermal stability. The novel ternary SA/PVA/BA bio-nanocomposite films have potential applications in biomedical and packaging fields.

Summary: A ferrocene-functionalized 2-phenylpyridine iridium(III) pentamethylcyclopentadienyl complex was synthesized and investigated for oxygen evolution from water. The high activity of this catalyst can be explained by a proposed Fe(III)/Ir(IV) transient intermediate, where bimetallic redox synergism between the Fe and Ir centers possibly provides an alternative pathway instead of a conventional Ir(V)-based cycle.

Summary: The aim of this research is to enhance the mechanical and water-resistance properties of soy protein isolate (SPI) biofilm. Modified nanocellulose with 3-aminopropyltriethoxysilane (APTES) was added to the SPI matrix with citric acid cross-linker. The results showed that the modified nanocellulose-incorporated film had better mechanical and thermal properties, as well as improved water resistance compared to the non-modified film. Additionally, the coating of citral essential oil onto the SPI nanocomposite film displayed antimicrobial properties.
