Summary: This study analyzes the influence of three key factors (solvent type, immersion time, and incubation temperature) on the quality of heptadecanoic acid self-assembled monolayer (SAM) on aluminum oxide. The results indicate that high solubility hinders the formation of high-quality SAMs, possibly due to the incorporation of solvent molecules into the monolayer.

Summary: Non-thermal plasma surface functionalization of polymeric materials has gained increasing attention in various application fields in recent decades. However, the diversity of chemical reactions occurring between the surface and the active species in plasma can result in non-specific surface functional groups. Achieving controlled surface chemistries can be challenging as it requires optimization of working parameters and comprehensive analysis of plasma-surface interactions.

Summary: The article investigates the role of single-layer graphene in the oxidation process of Cu substrates and reports the evolution of interfacial oxide layers of graphene/Cu samples over time. ARXPS study reveals that the thickness of the interfacial oxide layer is positively correlated with air exposure time, and the fractional coverage of the island-like interfacial oxide layer is in the range of 0.4-0.6. For graphene/Cu samples exposed to ambient conditions for less than 6 months, graphene can inhibit the formation of Cu2O, whereas it promotes the formation of CuO in the interfacial oxide layer for long-term oxidized graphene/Cu samples (>= 12 months), resulting in an embedded structure of the interfacial oxide layer. These findings can guide the corrosion protection of copper-based devices.

Summary: The development of potential resolved electrochemiluminescence (ECL) nanoluminophores is crucial for precise and multiplex analysis. In this study, a new nanoluminophore TCPP@CRuSiO2 was designed and synthesized, which exhibited both cathode and anode ECL emissions. The nanoluminophores had a uniform sphere morphology with a diameter of around 50 nm. They generated two ECL emissions at different potentials using K2S2O8 and tripropylamine (TPrA) as coreactants. The ECL mechanisms were proposed based on the reactions between different species. The synthesized TCPP@CRuSiO2 nanoluminophores not only possessed potential and wavelength resolved ECL emissions, but also showed advantages of easy synthesis, high ECL efficiency, good stability, and easy film formation on the electrode surface. This work enriches the study of ECL nanoluminophores and has important potential applications in precise and multiplex analysis.

Summary: This study proposes a method for sensitive and selective detection of Cu2+ and L-Met using Si NPs as a fluorescent probe. The Si NPs emitting orange fluorescence were prepared via hydrothermal treatment and showed quenching with Cu2+ and turn-on response with L-Met. The approach is fast, simple, cost-effective, and environmentally friendly, with lower detection limits than the levels of Cu2+ and L-Met in drinking water and human urine samples.

Summary: This study characterized the interaction between the Dengue fusion peptide (FLAg) and selected lipid Langmuir monolayers. The results showed that membrane charge and molecular organization play important roles in the peptide-lipid binding. The study also found that charged lipid monolayers had different peptide adsorption patterns, and FLAg changed the dipole orientation of the lipid polar head groups. Furthermore, FLAg assumed a hairpin configuration, which is essential for the membrane fusion process.

Summary: The influence of K-doping on the reactive oxygen species and elementary reactions of HCHO catalytic oxidation was investigated using density functional theory (DFT). The introduction of K-doping changed the electronic structures of Ce and O, facilitating the adsorption and activation of HCHO and O2 molecules, enhancing lattice oxygen mobility, and reducing the energy barrier for HCHO oxidation. K-doping also promoted the formation of hydroxyl groups, facilitating HCHO adsorption and oxidation.

Summary: In this study, the adsorption mechanisms and detection performance of formaldehyde, ammonia, and sulfur dioxide on undoped and metal-doped ZnO surfaces were investigated using density functional theory. The results showed that formaldehyde and ammonia were physically adsorbed on the undoped ZnO surface, while sulfur dioxide was weakly chemisorbed. The adsorption energy was enhanced when ZnO was doped with metals. These findings provide theoretical guidance for the application of ZnO substrate materials in gas sensitivity research.

Summary: This study investigates Si mass transport and morphological transformations on the Si(111) surface during (root 3 x root 3)-Sn reconstruction formation and Si homoepitaxy. The research shows that the formation of different Sn phases at different temperatures affects the Si island nucleation and monatomic step shift, which in turn impact the morphology of the Sn/Si(111) interface. Electromigration-induced drift of disordered Sn domains leads to enhanced noncompensated Si mass transport and surface roughening.

Summary: Deposition of thallium (Tl) onto the Au/Si(111)5 x 2 reconstruction followed by annealing results in the formation of a surface structure with 4 x 2 periodicity. The immiscibility of Au and Tl leads to the migration of Tl atoms over the Si chains. Thallium donates electrons to the surface, converting the metallic surface into an insulating state and altering the inter-chain distance within the array of Au atomic wires.

Summary: Using ab-initio calculations, the interaction between lead adatom and both clean and doped iron (100) surfaces was investigated. It was found that the lead adatom prefers to adsorb in the hollow site, which is more stable compared to the top and bridge sites, and in this position, it is energetically favorable over the iron adatom. Moreover, lead adsorbed in the hollow site of the iron (100) surface doped with chromium was found to create a more stable system compared to nickel-doped surfaces with an iron adatom in the same position. The study also explored inter-layer distances, bonding mechanisms, magnetic behaviors, and charge density differences. The results provide insights into the role of doping in the interaction between lead adatom and iron surface, and have implications for the analysis of corrosion processes caused by liquid lead.

Summary: Alkaline water electrolysis is a simple and efficient method for renewable hydrogen production, utilizing cheap and abundant transition metals. The catalytic properties of Ni materials are enhanced by the formation of oxidized compounds on the surface. The high electrocatalytic activity of Ni (oxy)-hydroxides is directly related to water intercalation in the passivation layer, supporting the hypothesis of a water mediated OH- diffusion mechanism. The self-organization of the surface structure during passivation layer formation enables high electrode performance.
