Summary: A highly efficient visible-light-driven photoanode, N-2-intercalated tungsten trioxide (WO3) nanorod, was successfully synthesized by using hydrazine (N2H4) as a structure directing agent and as a nitrogen source for N-2 intercalation. Controllable formation of WO3 nanorod was achieved by changing the amount of N2H4. The addition of N2H4 resulted in a redshift in absorption edge and the appearance of new shoulders in the UV-visible diffuse reflectance spectra.

Summary: A direct photocatalytic conversion of methane to formaldehyde over gold modified cuboid-shaped tungsten trioxide with exposed crystal-O facets has been reported, achieving high productivity and selectivity of formaldehyde under room temperature conditions. The activation of C-H bonds in methane by high spin state crystal-O ions, combined with the extraction of photoexcited electrons by metallic gold, results in efficient formation of formaldehyde. Isotopic tests confirm the origin of formaldehyde from the combination of methane and crystal-O on the exposed facets.

Summary: In this study, a facile surface treatment method using Fe2+ ions was demonstrated to enhance the photo-electrochemical water oxidation of nanostructured tungsten oxide (WO3) film. The optimized WO3 film with a Fe:W ratio of -1:25 showed a 3 times higher and more stable photocurrent under back illumination compared to untreated WO3, indicating the success of the surface treatment. The improved performance was attributed to the enhanced charge transfer process at the interface, resulting in the reduction of unwanted recombination.

Summary: In this study, the structural and electronic properties as well as the hydrogen evolution reaction (HER) activity of pristine, vacancy, and carbon (C) doped o-B2N2 monolayer are investigated using first-principles based density functional theory. The introduction of vacancy and C doping modifies the structure and electronic properties of the monolayer and enhances the HER activity of o-B2N2. The HER activity is increased by 77.34%, 86.71%, and 83.59% for the BN vacancy defect, C doping at B and N sites, respectively, compared to the pristine monolayer. The modulation in the HER activity is attributed to charge redistribution after the introduction of vacancy and dopant. The results suggest that C doping turns o-B2N2 into a metal, which can be used as an electrocatalyst, while BN vacancy defected o-B2N2 monolayer is a semiconductor with a band gap of -1 eV and can be utilized as a photocatalyst for HER activity.

Summary: Dental implants made from titanium and its alloys are commonly used due to their inertness and biocompatibility. However, to improve their success rate, it is necessary to enhance the integration with bone and gum tissues and prevent bacterial infections. Various surface modification techniques, including plasma electrolytic oxidation (PEO), have been explored. In this study, the use of nitrilotriacetic acid (NTA) as a complexing agent in the PEO process was found to improve the corrosion resistance of titanium implants and reduce bacterial colonization.

SEM, TEM, and STEM were used to analyze the microstructure, while XPS and APT were employed for chemical composition analysis. The study reveals significant microstructure evolution in the TNTZ alloy surface region due to DLIP treatment, along with local chemical heterogeneity of the alloy that was not considered before in design. The laser treatment homogenizes the remelted zones and influences surface properties.

Summary: The production and usage of lithium-ion batteries (LIBs) result in a significant increase in harmful waste, which raises concerns for environmental protection and metal resource scarcity. This paper proposes a novel application of a magnetorheological fluid (MRF) made from LIBs-based liquid waste containing heavy metal ions. The waste is treated with acid-leaching to obtain cobalt-doped superparamagnetic iron oxide nanoparticles (SPIONs), effectively purifying the waste from cobalt. The nanoparticles are then used to prepare the MRF, which demonstrates enhanced viscosity in the presence of magnetic fields. This work presents a cost-effective method for utilizing harmful waste from LIBs and provides a sustainable solution for waste management.

Summary: The study demonstrates that laser processing improves the biological responses of titanium surfaces. The Direct Laser Interference Patterning (DLIP) method is proposed as a single-step functionalization technique for pre-modified titanium surfaces in biomedical applications. Calcium phosphate coatings were deposited through immersion in Hank's solution to evaluate the biomedical potential of modified Ti substrates. X-ray photoelectron spectroscopy, scratch tests, scanning electron microscopy, and energy dispersive spectroscopy were employed to investigate the bioactive effect and adhesion force of the Ca-P coating. Overall, the results confirm the positive influence of laser treatment on bone-like apatite formation and surface wear resistance.

Summary: This study demonstrates the feasibility of introducing nitrogen into titanium dioxide nanotubes by plasma nitriding under ultra-high-vacuum conditions. The resulting nanotubes have a diameter of approximately 110 nm. The study also reveals that alternating nitriding and annealing processes at 450 degrees C lead to the formation of various chemical bonds in the TiO2 crystal structure. The photoactivity of the nitrogen-doped and annealed photoanodes is significantly higher than that of the non-doped ones. The highest maximum photocurrent density is achieved by the double-nitrided and once-annealed sample, which incorporates nitrogen mainly in the interstitial positions in the TiO2 lattice. The thermo-chemical treatment also extends the operational range of the photoanodes towards visible light. Rating: 9/10.

Summary: Compared to chiral iodoarenes in organocatalysis, stoichiometric oxidants can be replaced by electric stimuli in electrosynthesis. By screening reaction parameters, an enantioselective electrochemical oxidation mediated by a chiral iodoarene has been achieved for the first time. However, the efficiency is relatively low due to the difficult electrochemical oxidation of the applied iodoarene catalyst.

Summary: Density functional theory (DFT) calculations were used to investigate the feasibility of 2D alpha-CM (M = N, P) as an anode material for Li-ion batteries (LIBs). The results showed that 2D alpha-CP is a promising candidate due to its stability, high electronic conductivity, and high specific storage capacity. The adsorption of Li atom on 2D alpha-CP led to a change in its nature from semiconducting to metallic, resulting in substantial charge transfer and improved battery performance. A diffusion barrier of 0.11 eV also indicates high ionic mobility.
