Summary: This study explores the use of Ti3AlC2 MAX phase as a support for palladium nanoparticles to catalyze the removal of formaldehyde and production of hydrogen under mild conditions. By optimizing the experimental conditions, the Ti3AlC2/Pd catalyst exhibits a higher capability for hydrogen production and a lower apparent activation energy compared to conventional Pd nanoparticles.

Summary: This study presents an autonomous chemical synthesis robot that uses real-time spectroscopic feedback, theory, and machine learning algorithms to explore, discover, and optimize nanostructures. By controlling the reaction conditions and allowing selective templating of reactions, the robot achieves the transfer of materials as seeds between exploration cycles, similar to gene transfer in biology. Through the exploration of seed-mediated multistep synthesis, the robot discovered five categories of nanoparticles by performing only around 1000 experiments in three hierarchically linked chemical spaces. The platform optimizes nanostructures with desired optical properties by combining experiments and extinction spectrum simulations, achieving a yield of up to 95%.

Summary: This study proposes a chemical interface damping (CID) mechanism to explain the deviation of the optimal excitation wavelength (OEW) from the local surface plasmon resonance (LSPR). Simulations and experiments demonstrate that molecular adsorption-induced CID results in a significant red-shift of the OEW, beyond the region of LSPR, influencing the surface-enhanced Raman spectroscopy (SERS) measurements.

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: The present study synthesized Ni-M-Tb/Al2O3 (M: Mg, Ca, Sr, and Ba) nanostructured catalysts with different ratios of alkali metals by the ultrasonic-assisted one-pot method. The catalytic performance was evaluated through H2-TPR analysis, and the structural properties were characterized by XRD, SEM, TEM, and BET equation. The 2Ni-5Mg-5Tb/Al2O3 catalyst exhibited the highest CO2 conversion of 75.37% and CH4 selectivity of 100% at 400 degrees C with a molar ratio of H2:CO2:3.5 for 100 hours, attributed to the unique electronic structure of Tb in combination with Mg and Ni, which minimized agglomeration according to SEM and BET results. These findings suggest that tuning the combination of alkali and rare earth elements as promoters in Ni-based catalysts could lead to novel catalysts with high CO2 conversion efficiency to CH4.

Summary: The dispersion of nickel catalysts plays a crucial role in CO2 methanation reactions. Various fabrication methods, including ultrasonic, hydrothermal, microwave, and co-precipitation, have been used to prepare 25Ni-5Er-Al2O3 catalysts. Among them, the ultrasonic method shows the best catalytic performance in terms of methane selectivity at a temperature of 400 degrees C. The addition of Erbium promotes the dispersion of nickel on the supports and enhances the reaction due to erbium oxygen vacancies.

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.
