Summary: In this study, we investigate the atomic structures and electronic properties of the As-terminated GaAs(001) surface in the presence of hydrogen using ab initio density functional theory. By calculating energy landscapes and density of states, we provide a phase diagram dependent on the chemical potentials of As and H, and show the effect of hydrogen adsorption on the states near the fundamental band gap.

Summary: The anodization of titanium is an effective method to protect titanium and its alloys from corrosive environments. In this study, the electrochemical corrosion behavior of Ti-6Al-2Sn-4Zr-2Mo and Ti-6Al-4V alloys anodized in 1M H2SO4 and H3PO4 solutions was evaluated. The anodized samples showed changes in E-corr values and a higher passivation zone. EIS analysis revealed a higher resistance for samples anodized in H3PO4 and Ti-6Al-2Sn-4Zr-2Mo.

Summary: The time-dependent corrosion behavior of pure aluminum (Al) in a chloride-containing environment was studied. It was found that the surface film of pure aluminum continuously dissolved over time, while the increasing thickness of the passive oxide film enhanced the resistance. Corrosion kinetics increased in the early stage of immersion due to accelerated localized corrosion, but were inhibited after longer immersion times due to corrosion product deposition.

Summary: This study investigates the adsorption structure and mechanism of imidazolium-based ionic liquids (ILs) as corrosion inhibitors for iron using density functional theory (DFT) and ab initio molecular dynamics (AIMD). The results show that ILs strongly adsorb on the metal surface through chemisorption. The alkyl chain length of the cation significantly affects the adsorption energy. DFT calculations provide more accurate modeling of the adsorption process compared to classical molecular dynamics calculations. This computational study contributes to understanding the nature of adsorption in green and sustainable corrosion inhibition using ILs.

Summary: The investigation presents the superior corrosion inhibition capabilities of two novel indoline compounds for oil well/tubing steel in 15% HCl solution. The gravimetric studies confirm high corrosion inhibition efficiency, while the electrochemical analysis approves the reduction in cathodic corrosion reaction and anodic reaction due to inhibitor adsorption. The substrate surface analysis reveals the formation of a protective film to protect the surface from aggressive acid solution, and theoretical studies support the experimental corrosion parameters.

Summary: The corrosion inhibition effects of a novel thiazolidinedione derivative named B1 were investigated on mild steel in 1 M HCl using gravimetric analysis, electrochemical analysis, and Fourier transform infrared spectroscopy. B1 showed a maximum percentage inhibition efficiency of 92% at 303.15 K in gravimetric analysis and 83% in electrochemical analysis at the same temperature. Thermodynamic parameters indicated that B1 adsorbs onto the MS surface via a mixed type of action at lower temperatures and exclusively chemisorption at higher temperatures.

Summary: Mineral coatings have shown great potential in combating wear and corrosion in industries at a cost-effective ratio compared to synthetic ceramics. This study focuses on the deposition of chromite coatings with a high concentration of Chromium oxide (Cr2O3) on steel substrates using High Velocity Oxygen Fuel (HVOF) and Atmospheric plasma spray (APS) techniques. The effects of deposition processes and Cr2O3 enrichment on the microstructure, hardness, tribological, and electrochemical behavior of the coatings are investigated. Results indicate that coatings deposited with APS exhibit excellent wear resistance, and higher Cr2O3 content contributes to improved hardness, compactness, tribological, and corrosion performance.

Summary: High-spatial-resolution local electrochemical impedance spectroscopy (LEIS) was achieved using scanning electrochemical cell microscopy (SECCM-LEIS), with a spatial resolution of approximately 180 nm. The stability and reliability of this platform were confirmed through long-term tests and Kramers-Kronig transformation. This technology revealed larger electric double-layer capacitance and smaller interfacial resistance at the edges of N-doped reduced graphene oxide compared to the planar surface, suggesting high electrochemical activity at the edges.

Summary: A method using 3D printing technology to prepare ZVI@PLA catalysts without post etching treatment was reported. The use of non-contact heating by magnetic induction (MIH) was shown to reactivate the surface of the catalyst, allowing for the ZVI@PLA catalyst to be reused up to 10 cycles with maintained efficiency. On the other hand, traditional thermal bath heating resulted in a gradual decrease in kinetic constant over 10 cycles.

Summary: Fe3O4 catalyst was synthesized in a single step via electrochemical synthesis for the degradation of Ofloxacin (OFX) using sodium persulfate (PS). The effects of catalyst and oxidant concentration, as well as temperature, on the degradation kinetics were studied. The results showed that higher reaction temperature, catalyst, and initial PS dose strongly influenced the degradation efficiency. Thermal activation of persulfate at 60 degrees C resulted in a much greater degradation efficiency compared to 20 degrees C.

Summary: The temperature effect on the corrosion inhibition process of API 5L X60 steel in 1 M H2SO4 was studied using three vinylimidazolium poly(ionic liquid)s (PILs) by electrochemical techniques, surface analysis, and computational simulation. The maximal inhibition efficiency (75%) was achieved by Poly[VIMC4][Im] at 308 K and 175 ppm. PILs exhibited E-corr displacements indicating mixed-type corrosion inhibitors (CIs). The presence of PILs resulted in less surface damage, confirming their inhibiting effect.

Summary: In this study, 15 ionic liquids (ILs) derived from quaternary ammonium and carboxylates were synthesized and characterized. Their evaluation as corrosion inhibitors (CIs) for API X52 steel in 0.5 M HCl was conducted. Potentiodynamic tests showed that the inhibition efficiency (IE) varied with the chemical configuration of the anion and cation. The ILs were found to be mixed-type CIs and the IE was directly proportional to the CI concentration. Surface analysis by scanning electron microscopy confirmed the reduced steel damage in the presence of CI due to the inhibitor-metal interaction.

Summary: This study focuses on manganese doped CdS thin films synthesized by chemical bath deposition. The incorporation of Mn2+ cations in CdS was found to influence the crystalline structure, morphology, and optoelectronic properties. Doped thin films exhibited a uniform hexagonal structure, changed growth orientation, and showed scale-like and needle-like morphologies. The bandgap and rectification speed of Schottky diodes were modified by introducing manganese. This study suggests the potential for affordable high-speed optoelectronic devices.
