Summary: The SARS-CoV-2 pandemic has led to increased interest in durable, cost-effective, and environmentally friendly antipathogenic coatings for high-touch public surfaces. In this study, cuprous oxide powder was rapidly nanostructured using high-energy cryomechanical processing, resulting in coatings that exhibited a passive contact-kill response to E. coli bacteria. The processed cuprous oxide coatings showed a significantly faster bacteria reduction compared to unprocessed coatings and no viable bacteria were detected after two hours of exposure.

Summary: Metallic glasses are promising catalysts for dyeing wastewater remediation due to their metastable nature, but the influence of inorganic ions on their degradation capability needs to be systematically studied. Different inorganic ions have significant effects on the surface morphology, degradation capability, mineralization, and durability of metallic glasses, which should be considered before their application for dye degradation in contaminated water or saline wastewater.

Summary: The use of a sn-containing binary co-catalyst enhances the performance of Pd in the photocatalytic production of green hydrogen from methanol:water mixtures. A Pd:Sn molar ratio of 1:1 leads to an outstanding enhancement of activity under UV, visible and sunlight illumination, with a quantum efficiency value of 4 % in the latter case. The interaction between Pd metal nanoparticles and Sn oxo-hydroxyde nanoentities results in an electronic modification of both components.

Summary: Different materials based on an L-rich polylactide (PLA) matrix, acetyl tri-n-butyl citrate (ATBC) plasticizer, and mesoporous MCM-41 particles as nucleating agent were obtained by melt extrusion. The incorporation of plasticizer and nucleating particles reduced the phase transition temperature of PLA and promoted its crystallization. A significant increase in PLA crystallization rate was observed due to the synergistic effect of ATBC and MCM-41.

Summary: Diamond properties can be controlled by doping and ion-beam irradiation, which can also cause damage and other aftereffects. Boron doping is of particular interest as it can turn diamond into a p-type semiconductor at suitable concentrations and a superconductor at higher concentrations. However, the creation of superconducting boron-doped diamond is hindered by amorphization and graphitization after annealing. This study analyzed the damage and recovery of diamond irradiated with 9 MeV B ions at different fluences, using various techniques. The results showed that higher fluences led to carbon migration and increased amorphous fraction, while low fluences could fully recover the diamond structure without graphitization. However, annealing at 1200 degrees C for high fluences caused incomplete healing and the presence of graphite traces.

Summary: Functionalized silver nanoparticles were successfully incorporated into PLA solutions to produce multifunctional polymeric fibers using centrifugal force-spinning. The effects of nanoparticle incorporation and fiber preparation method on morphology, thermomechanical properties, biodisintegration, and antimicrobial behavior were investigated. The results showed that the best thermomechanical behavior was achieved with 1 wt% of nanoparticles, and the fibers exhibited antibacterial activity with a killing percentage between 65 and 90%. All samples were disintegrable under composting conditions. Additionally, a good thermally activated shape-memory effect was observed in fiber mats with 2 wt% of nanoparticles.

Summary: Composites based on PLLA and MCM-41, either neat or modified with Ag, are prepared and show antimicrobial properties. The thermal stability, nucleation efficiency, and mechanical response of PLLA are influenced by MCM-41 nature and content. WAXS measurements reveal the formation of ordered ff crystals in the composites containing MCM-41@Ag. The composites with higher silica content exhibit higher MH values and remarkable antimicrobial features.

Summary: Structure-sensitive catalyzed reactions can be influenced by several parameters. It has been established that Pd-C species are responsible for the behavior of Pd nanoparticles in a butadiene hydrogenation reaction. Experimental evidence suggests that subsurface Pd hydride species govern the reactivity of this reaction, and the formation/decomposition of PdHx species is sensitive to the dimensions of Pd nanoparticle aggregates, which controls the selectivity in this process. High-energy X-ray diffraction (HEXRD) is the main methodology used to determine this reaction mechanism.

Summary: A series of catalysts with increasing amounts of Niobium were prepared using Pd as a co-catalyst and a high surface area titania support. The samples exhibited a consistent Pd particle size of approximately 4.6 nm, and Niobium was found to be present in the pores of anatase without affecting the primary particle size of the main oxide. The activity of the samples in hydrogen production under UV and visible illumination was tested and measured, showing that the optimal catalyst contained 1 mol. % of Niobium and demonstrated a quantum efficiency value of 2.8%.

Summary: This research analyzed the impact of adding zirconium oxide to titanium oxide-supported gold systems on photocatalytic hydrogen production. The highest activity was achieved with a 1.75 mol.% zirconium oxide, showing a quantum efficiency close to 1.9% under sunlight, which was over two orders of magnitude improvement compared to the original titanium system. The addition of zirconium influenced the recombination of charge carriers and boosted photoactivity through the interaction between gold and zirconium.

Summary: In this research, composite catalysts based on mixtures of titanium and cobalt oxides were synthesized and tested for thermo-photo reduction of carbon dioxide. The results showed that the sample doped with 4% Co exhibited the best catalytic performance, achieving high selective production of carbon monoxide. The physico-chemical characterization revealed that the cobalt oxide was embedded in nanocrystalline anatase nanoplatelets in an amorphous form. In-situ infrared analysis provided conclusive evidence for the promotion of catalytic performance under dual excitation.
