Summary: The role of subsurface carbon and the synergistic effects of Au and KOAc in the acetoxylation of ethylene have been investigated. The presence of subsurface carbon in Pd-Au/SiO2 catalyst was found to enhance the catalytic performance in VAM synthesis. Experimental and theoretical analysis also suggests that the coupling reaction between acetate and ethylene is effectively promoted by the synergistic contributions of Au and interstitial carbon, inhibiting ethylene dehydrogenation and CO2 formation. These insights provide new possibilities for the design of catalysts with improved catalytic performance.

Summary: The NiSe2/Ni3Se4 dual-phase electrocatalysts synthesized on Ni foam show improved efficiency in oxygen evolution reaction (OER) and hydrogen evolution reaction (HER), with lower voltage and good durability. The composition of the catalyst influences the charge-state of Ni and the phase distribution, impacting the catalytic performance significantly. The interfacial electron transfer between Ni3Se4 and NiSe2 enhances conductivity and improves adsorption/desorption energies, contributing to the overall efficiency of the electrolyzer.

Summary: PdxSny nanoparticles (NPs) synthesized using an oil-bath method exhibit excellent electrocatalytic activity in ethanol oxidation reaction (EOR), with Pd20Sn24 (x/y=0.83) NPs showing the best performance. The enhanced performance of PdxSny NPs may be attributed to changes in the electron structure of Pd, varied interatomic distance within a unit cell, and weak adsorption of oxygen or carbon-containing intermediate species. Experimental data suggest that higher catalytic temperature, higher pH values, and higher ethanol concentration can accelerate each step of electrooxidation in EOR.

Summary: In this study, we investigated the reduction reaction kinetics of ciprofloxacin organic molecules on Bi05Na05Ba(TiO3)2 (BNT-BT) thin films based on their structural and micromorphological conditions. XRD and Raman spectroscopy confirmed the presence of surface defects and the coexistence of rhombohedral and tetragonal structures in the annealed BNT-BT thin films. We found that BNT-BT thin films annealed at 600 degrees C exhibited unique structural and micromorphological properties, which resulted in their superior electrocatalytic performance compared to films annealed at higher temperatures.

Summary: This study investigated the structural modifications and electronic behavior of composites obtained from the admixture of a biphasic titanate ceramic system (Na2Ti3O7/Na2Ti6O13) with a poly(o-methoxyaniline, POMA) matrix. The addition of sodium titanates to the POMA matrix increased the thermal stability of the composites and significantly increased the electrical resistivity. The XRD, FTIR, and UV-Vis analysis revealed mostly the presence of POMA, but the titanates could be identified in the composites with higher concentration.

Summary: This work reports on the variation in the structural and electrical properties of lithium-doped sodium titanate synthesized through an ultrafast microwave-assisted method. X-ray diffraction and Rietveld analysis were used to identify the phases present and their composition. Na2Ti3O7 was identified as the main phase, while Na2Ti6O13 was obtained as a secondary phase in all samples. The addition of 0.5% lithium ions resulted in the appearance of an additional phase, NaLiTi3O7. The microstructure of the ceramic samples showed increased grain size and the presence of small particles on the grain surface. The electrical properties of the samples were improved with increased doping, with sigma(dc) values of 1.94 x 10(- 5) S cm(- 1), 2.51 x 10(- 5) S cm(- 1), and 4.00 x 10(- 5) S cm(- 1) determined for Na2 - xLixTi3O7 with x = 0.0%, 0.1%, and 0.5% of Li+.

Summary: This work investigates the impact of lithium hydroxide (LiOH) amalgamation on polyvinyl alcohol thermoplastic membranes obtained by the solvent casting method. The results suggest that Li+ ions affect the vibrations of C=O, C-O, and O-H functional groups, as evidenced by FTIR and Raman spectroscopy. The semi-crystalline nature of the samples is confirmed by X-ray diffraction analysis. Density functional theory calculations reveal an insulator-metal transition due to the incorporation of lithium in the polymer. Furthermore, the complex impedance study shows that the resistance values of the membranes improve with an increase in lithium content, up to 7% of LiOH (7*10(2) Omega). These findings highlight the importance of such materials as potential candidates for solid-state electrolytes.

Summary: In this study, the effect of Sn-substitution on the electrical conductivity of SrFe12O19 hexaferrite synthesized by the solid-state reaction method was investigated. The complex impedance curves of samples containing Sn(4+) cations show the existence of conductive processes. The conductivity values increase with the dopant cations content in the Sn-doped SrM ceramics samples. Additionally, the Sn4+ cations insertion in the SrM crystal structure contributes to the emergence of two conductive processes: a DC-conductivity process at low frequency and a second frequency-dependent conductive process at high frequency. The existence of a small polarons tunneling mechanism with long-range mobility and low frequency and an electron hopping mechanism with a correlated barrier model and activation energy ranging from 0.135 to 0.355 eV were found.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
