Summary: Electrode materials for electrochemical hydrogen storage (EHS) were synthesized using the sol-gel process with PrCoO3 Perovskite, CuO, and Graphitic carbon nitride. Flower-like structures with PrCoO3 nanoparticles on scaly-shaped CuO on g-C3N4 nanosheets were observed by SEM. The effect of natural fuel and maleic acid on the synthesis of PrCoO3 was compared. X-ray diffraction showed pure phase of PrCoO3 at 700 degrees C, but impurity phases were present at 600 and 800 degrees C. PrCoO3/CuO/g-C3N4 exhibited higher hydrogen storage capacity compared to pristine PrCoO3. The improved performance suggests the potential application of PrCoO3/CuO/g-C3N4 in electrochemical hydrogen storage.

Summary: A group of rare-earth metals functionalized mesoporous Ni-M/Al2O3 (M = Tb, Dy, Nd) composite oxides were prepared and applied in the CO2 methanation process. The addition of terbium (Tb) improved the catalytic performance, particularly at low temperatures. The superior catalytic performance of 25Ni-5Tb-Al2O3 could be attributed to the appropriate fabrication method and the promotion effect of terbium.

Summary: The treatment of real or synthetic industrial effluents and the study of photocatalysts have attracted a lot of attention from scientists. Among various metal oxide photocatalytic materials, narrow bandgap compounds are particularly significant for their suitable efficiency in optical applications. In this study, pristine ErVO4 was synthesized using the microwave-assisted method, with different solvents and power intensities employed for size and shape control. The properties of the samples, including phase purity, surface area, magnetic and optical features, were analyzed. Microwaves with a power of 900W and ethylene glycol solvent were found to be optimal conditions for generating uniform nanosized particles. The nanostructured ErVO4 was used as a catalyst for the decolorization of colored pollutants, showing high photocatalytic efficiency in experiments with different dye concentrations and catalyst loadings.

Summary: Recent years have witnessed the growing prominence of implants in the health field and the revival of damaged organs. Planktonic bacteria on the surface of implants pose risks of infections and biofilm formation, which can lead to severe pain and even death. The risk of infection after orthopedic surgery remains high. Biofilm infections destroy adjacent tissues and hinder antibiotic delivery, making treatment difficult. Topical drug delivery, using antibiotic-loaded implants, metallic and metal oxide nanoparticles, polymers, and antimicrobial peptides, offers promising solutions to reduce these risks.

Summary: With increased development and electricity generation, it is crucial to consider energy storage systems to overcome the discontinuity in renewable production. Hydrogen is an ideal energy carrier for future mobility, such as automotive applications. However, current hydrogen storage materials do not meet all requirements in terms of storage capacity and commercialization. Developing new materials with large surface area, homogeneous texture, active-conductive profiles, large oxygen vacancies, and low cost is crucial. Multiphase materials composed of these materials can meet the requirements in this field.

Summary: In this study, a type-I DyVO4/AgBr heterojunction was prepared using a simple and cost-effective co-precipitation method, exhibiting excellent performance as a photocatalyst for water treatment. The reaction temperature and molar ratios of H2Salen to dysprosium were found to significantly impact the morphology of the synthesized products. Comparative photodegradation experiments demonstrated that DyVO4/AgBr outperformed pure DyVO4 and AgBr under both UV and visible light, degrading 79.8% and 72.0% methylene blue, respectively, after 90 minutes of exposure. The kinetics study revealed that DyVO4/AgBr exhibited the highest rate constant (k = 0.0187 min-1) for photodegradation.
