Summary: This study investigates the selectivity of acetylene over CeO2 supported single Pd catalyst and PDO-liganded Pd single catalyst using density functional theory calculations, microkinetic modeling, and ab initio molecular dynamics. The results show that PDO ligand stabilizes the single Pd catalyst through strong Pd-O/Pd-N interaction, leading to higher C2H4 formation selectivity.

Summary: In this study, the direct bonding between copper foil and PEEK film was achieved using nanosecond lasers. The surface of the copper foil was modified through UV/ozone and silane coupling treatments to enhance the interfacial bonding. The modified Cu/PEEK joints exhibited a significant improvement in peel strength, and the interaction between the treated copper foil and PEEK film was found to involve strong hydrogen bonding.

Summary: This study investigates the structural, optical, and superhydrophilic properties of zinc oxide pillars prepared by pulsed laser deposition at a high temperature. The results show that the samples prepared at high temperature exhibit larger crystallite size, higher surface roughness, improved light absorption, and enhanced superhydrophilicity. These properties are attributed to the increased interstitial zinc concentration and decreased oxygen vacancy concentration.

Summary: This study demonstrates the preparation of a high SERS activity and plasmonic photocatalytic properties nanoarray, SA-Ag/Au HCNAs, by combining Ag/Au hybrid coupled films with a sapphire array. The prepared SA-Ag/Au HCNAs show significantly enhanced plasmonic photocatalytic properties compared to pure Au and pure Ag. They also exhibit good stability and sensitivity as SERS substrates for probe molecules. This work provides a simple, low-cost, and scalable method for the preparation of hybrid coupled nanoarrays with potential applications in photocatalytic dye degradation, environmental monitoring, and biomedical analysis.

Summary: This study successfully prepared a pyrazole-directed functionalized leather waste collagen fiber composite and investigated its capture effect and mechanism on iodine vapor. The results showed that the composite had a high iodine capture capacity, which was primarily attributed to the existence of active functional groups and charge transfer between the pyrazole moieties and iodine.

Summary: In this study, borophene quantum dots were scaffolded on TiO2 nanoparticles, resulting in enhanced photoelectrochemical water splitting activity. The optimized concentration of borophene quantum dots on TiO2 nanoparticles showed a lower effective absorption edge, indicating improved photoelectrochemical response. Various characterization techniques confirmed the presence and effect of borophene quantum dots on the nanocomposite. The results suggest that the BPQDs/TiO2 nanocomposite exhibits improved photoelectrochemical water splitting activity due to the synergistic effects of the individual components.

Summary: In this study, it was found that fitting the C 1s core level spectrum of graphene grown on Ir(111) using 200 peaks based on ab initio calculations, considering non-equivalent C atoms, does not improve fit quality. On the contrary, introducing a dependency of the Lorentzian width on the distance between C and Ir first-layer atoms can significantly enhance the quantitative fit quality, indicating the different electronic properties and density of states of C atoms in different regions of graphene.

Summary: Resonant Acoustic Mixing (RAM) is used to modify the surface of milled carbon fiber quickly and without solvents, allowing for tuning of surface properties and reducing environmental impact. Fluorine-containing diazonium salts were successfully grafted onto the carbon fiber, maintaining surface integrity and increasing water contact angle. RAM proved more efficient than thermal treatment in solvent.

Summary: The structure-activity relationship of alcohol in the synergism between benzohydroxamic acid (BHA) and alcohol as mixed collectors was investigated. The results showed that an appropriate molecular structure of alcohol was advantageous for ilmenite flotation with BHA/alcohol collectors. The positive synergism was observed in BHA/alcohol systems at the gas-liquid intersurface and liquid phase, where mixed micelles were formed through hydrogen bonding and van der Waals interactions between BHA and alcohol molecules.

Summary: In this work, the dissolution of UO2 in pure water and aqueous solutions exposed to gamma-radiation was experimentally studied. The results showed that high ionic strength and solution pH affected the adsorption of dissolved UO?+ on UO2 surfaces. Additionally, Br3- was observed in the solution containing Br- and it was found to quantitatively oxidize UO2. XPS and UPS analyses revealed significant oxidation of UO2 surfaces after exposure, with U(V) as the dominant state. In the case of pure water, the formation of uranyl peroxide secondary phases was observed. UPS results indicated the presence of U(VI) on the outer layer of UO2 after exposure to aqueous solutions containing Br- and Cl-, while 100% U(VI) was found in the pure water case.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: Ion beam erosion of Si under co-deposition circumstances can form surface patterns on the nano- and micrometer scale. This study investigates the effect of surfactant sputtering on ultra precision surface finishing. It is found that the formation and evolution of structures on the substrate are induced by the silicide-forming metals, leading to higher surface roughness. On the other hand, non-silicide-forming metals do not show patterning and result in lower surface roughness. Additionally, the co-deposition material affects the Si removal rate, with the scattering and sputtering properties playing a role in determining the removal change.
