Summary: This study investigates the interface chemistry of organosilane self-assembled monolayers (SAMs) through the use of time-of-flight secondary ion mass spectrometry (ToF-SIMS). A comparison of ion fragmentation differences between octadecyltrimethoxysilane (OTMS) SAMs, free OTMS molecules, and oxide substrates was conducted. It was demonstrated that ToF-SIMS is capable of verifying the hydrolysis of OTMS molecules and assessing the polymerized -Si-O-Si- network in their SAMs. This provides unique information for understanding the interface chemistry of OTMS SAMs formed on oxides.

Summary: The effect of chemistry change on corrosion mechanisms and passive film characteristics of model Ni-P and Co-P metallic glass coatings on mild steel was investigated. Increasing phosphorus content enhanced corrosion resistance, with the presence of hypophosphite and phosphate anions observed on the corroded surfaces. Enrichment of phosphorus in the passive layer facilitated the restoration of the protective hypophosphite anion layer during dissolution. A correlation between electronic structure and corrosion resistance was established, as the relative work function increased with higher phosphorus content.

Summary: This study reveals the nanoscale origin and important characteristics of enhanced dielectric breakdown capabilities in gold nanoparticle/polymer nanocomposites. The improved breakdown strength is related to the interfacial charge retention capability at the nanoscale. At the meso- and macroscales, the concentration and distribution of nanoparticles play a crucial role in determining and enhancing the dielectric properties.

Summary: The formation and surface structure of pentafluorobenzeneselenolate (PFB-Se) self-assembled monolayers (SAMs) on Au(111) were examined by scanning tunneling microscopy (STM). Results showed that the structural order of the SAMs was improved by vapor deposition compared to solution deposition. Kelvin probe force microscopy measurements exhibited a significant difference in the work function between pentafluorobenzenethiolate and PFB-Se SAMs due to their different domain and packing structures.

Summary: In this study, the use of SAMs formed from disulfide lipoic acid-based compounds significantly improved charge injection in organic semiconductor devices by altering the interaction between the polymer and the metal surface. This research sheds light on how the nature of functional groups in SAMs and the number of bonds formed with the metal electrode influence the performance of organic semiconductor devices.

Summary: Molecules of 12-o-carboranyldodecylphosphonic acid can form a novel self-assembled monolayer on alumina, effectively tuning charge carriers in organic field effect transistors by assembling dipoles at the semiconductor-dielectric interface. This SAM enables p-channel OFETs of pentacene and ambipolar charge transport in n-type organic semiconductors like chlorinated tetraazapentacene, while the surface electrostatic potential of the SAM correlates with the observed shift of threshold voltage in OFETs.

Summary: In this study, a water transfer method was developed to fabricate thin-film patterns on 3D curvilinear surfaces. By suspending crystalline silver nanoplates in ethanol with a surfactant and spreading the suspension over the water surface, a self-assembled thin film was generated. The thin film could be effectively transferred to object surfaces with nanometer thickness and exhibited superior conductivity without thermal sintering.

Summary: This study combines electrochemical and XPS experiments to investigate the conformational rearrangement of self-assembled monolayers (SAMs) on an electrode surface due to the application of an electrical field. It was found that activation and deactivation processes play a crucial role in reaction yields and conformational rearrangement, ultimately impacting the performance of bioelectronic devices.

Summary: The adsorption of octadecylphosphonic acid (ODPA) on copper substrates was studied, showing that a multilayer film was formed with increasing deposition time. The robustness of the film was attributed to the formation of Cu-ODPA complexes. Preadsorbing a monolayer of octadecylthiol (ODT) prevented the adsorption of ODPA by abolishing the release of Cu(I) ions.

Summary: Sodium-metal chloride batteries are a sustainable and safe alternative to lithium-ion batteries for large-scale stationary electricity storage, but their rate capability is limited. Metal-ion diffusion in the electrolyte is found to limit the chlorination process of both nickel and iron electrodes, instead of metal-ion migration through the metal chloride conversion layer.

Summary: Rechargeable all-solid-state Li batteries with solid electrolytes are a promising solution for safe and high capacity energy storage. In this study, Neutron Depth Profiling (NDP) was used to investigate the response of a potential electrolyte, Lithium Conductive Glass Ceramic (LICGC), to applied voltage. The in-situ NDP measurements allowed for direct monitoring of lithium ion migration and quantification of the formation of a space charge layer with depleted Li atoms, which depended on biasing time.

Summary: In modern oral maxillofacial surgery, long-term stability of implants is closely related to the quality of osseointegration. This study investigates the influence of femtosecond laser-texturing on physicochemical properties, blood-implant interactions, and osseointegration potential of titanium-aluminium-vanadium (TiAlV) implant surfaces. Laser-texturing enables the production of designer surfaces with defined micro-scale features, showing comparable biological performance to state-of-the-art implants.

Summary: In this study, electrodeposited manganese oxides (MnyOx) films were used as a visible-light-driven photocatalyst for the removal and mineralization of Tetracycline (TC) antibiotics. The best performing manganese oxide showed 92.4% TC mineralization efficiency after 180 min of LED visible illumination. Hydroxyl radicals (center dot OH) were found to be the main active species responsible for the TC degradation. The degradation of the oxide surface structure was identified as the key factor limiting the photocatalytic activity.
