Summary: Five systems of Ti alloys with 10 wt % of the second metal were electrochemically synthesized in a fluoride-containing ethylene glycol-based electrolyte. Results showed that the Ti90Ag10_40V sample exhibited the highest photocatalytic and photoelectrochemical activities, potentially due to the heterojunction between the oxides, formation of single Ag nanoparticles, and high level of self-organization.

Summary: Heavy metal pollution, especially chromium contamination, is a significant problem in water treatment. Traditional methods for treating chromium-containing wastewater have limitations in terms of complexity and secondary pollution. Therefore, finding efficient and fast processing methods is crucial. In this study, a novel composite gel (T-BSA) was synthesized by modifying sodium alginate with thiourea and mixed with biochar. The T-BSA gel showed promising results in removing 99.98% of Cr(VI) from aqueous solutions through synergistic adsorption and photocatalytic reduction under UV light irradiation. The study also analyzed the mechanism behind the removal process and demonstrated that polysaccharide-derived materials can serve as efficient photocatalysts for wastewater treatment.

Summary: The bio-inertness of titanium and severe inflammation can inhibit the regulation of osteogenesis-angiogenesis and lead to poor osseointegration of peri-implant. In this study, TiO2 nanotubes of different diameters were prepared on titanium substrate and TNT-70 showed the most significant induction of macrophage differentiation to the pro-healing M2 phenotype. TNT-70 also stimulated the osteogenic potential of MSCs and the angiogenic ability of HUVECs through paracrine signaling. In vivo experiments demonstrated that TNT-70 relieved inflammation, facilitated osteogenesis and angiogenesis, and promoted osseointegration of peri-implant.

Summary: In this study, a novel composite material was synthesized by blending CuS nano-crystals into triethylenetetramine modified sodium alginate, showing high adsorption ability for Cr(VI) and enhanced photocatalytic removal. The effects of CuS dosage, pH value, light source, and intensity on Cr(VI) removal were investigated. The synthesized composite achieved a removal rate of 98.99% within 50 minutes under UV light irradiation with citric acid as a hole scavenger. The adsorption isotherm, thermodynamics, and kinetics were discussed, indicating that monolayer and chemical adsorption were dominant mechanisms. Amino and hydroxyl groups contributed electrons in the photocatalysis reaction for the reduction of Cr(VI) to Cr(III). CuS nanocrystals enhanced the surface charge and light absorbance ability of the composite, governing the electrostatic interaction and photo-induced redox reaction in Cr(VI) removal.

Summary: Electrochemical studies and microstructure analysis were conducted on directionally solidified hypoeutectic and eutectic aluminum-copper alloys. The addition of copper in the alloys was found to increase the corrosion susceptibility due to the formation of cathodic sites, while an increase in the concentration of Al2Cu intermetallic compound resulted in higher corrosion susceptibility. The morphology of the microstructure played a crucial role in enhancing the corrosion resistance of the Al-Cu alloys.

Summary: The anodic oxidation of aluminium is an electrochemical technique that can be used to obtain low-cost nanoporous aluminium oxide films with varied morphology depending on synthesis variables. The best ordering conditions were found to be using two anodization steps in sulphuric acid at 10 degrees C and 0.3 M concentration, as well as at 5 degrees C and 2 M concentration. The pore diameter, interpore distance, and thickness of the oxide film were found to vary proportionally with changes in the anodization voltage.

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.
