Summary: In this study, laminated reduced graphene oxide (rGO) was used to induce the growth of SnCoS4 particles and self-assembled into a nanosheet-structured SnCoS4@rGO composite through a solvothermal procedure. The optimized material showed abundant active sites and facilitated Na. ion diffusion due to the synergistic interaction between bimetallic sulfides and rGO. As the anode material of sodium-ion batteries, this composite maintained a high capacity of 696.05 mAh g-1 after 100 cycles and a high-rate capability of 427.98 mAh g-1 even at a high current density of 10 A g-1. Our rational design provides valuable inspiration for high-performance sodium-ion battery anode materials.

Summary: By controlling the dosage of triethanolamine, two nanocomposites of monoclinic-ZrO2@rGO and tetragonal-ZrO2@rGO were successfully prepared, with the tetragonal-ZrO2@rGO exhibiting a higher adsorptive amount for OTC. Both nanocomposites show a selective uptake of OTC among tetracycline antibiotics, with adsorption reaching equilibrium in 15 minutes and being independent of pH in the range of 4-8. The interactions between OTC and the nanocomposites were revealed through Fourier transform infrared and XRD analysis, with surface complexation, pi-pi, and cation-pi bonding interactions playing a crucial role.

Summary: This study aims to achieve high mineralization efficiency of oxytetracycline (OTC) in a dissolved oxygen (DO) activated Fenton-like system by constructing a catalyst with unique catalytic performance. The synthesized three-dimensional graphene anchored nZVI hybrid MnO2 (3D-rGO@nZVI/MnO2) with layered and porous structures was characterized. The experimental results showed that OTC removal efficiency reached 100.0% with outstanding total organic carbon (TOC) decrease of 84.0% in the 3D-rGO@nZVI/MnO2-DO system. Reactive oxygen species (ROSs) detection and analysis confirmed the unique catalytic degradation mechanism of OTC in the system.

Summary: Temperature has a significant effect on adsorption processes, particularly on adsorption equilibrium. While the effect of temperature on adsorption kinetics has been less explored, likely due to a lack of a simple and suitable kinetic model. This study analyzed kinetic data using the Elovich equation and found that most adsorption processes had an activation energy in the range of 12.1 to 25.6 kJ mol(-1).

Summary: In this study, chitosan (CS) and graphene oxide (GO) were combined to synthesize CS/GO composites with different GO contents. The combination of CS and GO not only improved the surface area by reducing agglomeration of GO sheets, but also significantly enhanced the adsorption capacity of cationic dye on CS. The Langmuir adsorption capacity of methylene blue (MB) reached 259.5 mg/g at pH 8 and 30 degrees C for the CS/GO12 material. The composite showed good adsorption-regeneration performance.

Summary: This study experimentally confirmed the absorption of carbon dioxide (CO2) from CO2-N2 gas mixtures using water and monoethanolamine (MEA) solution in polypropylene (PP) hollow-fiber membrane contactors. Gas flow occurred inside the module while the absorbent liquid flowed counter-currently outside the shell. Various gas- and liquid-phase velocities as well as MEA concentrations were tested, and the effect of pressure difference between the gas and liquid phases on CO2 absorption was investigated. A simplified mass balance model incorporating the non-wetting mode and overall mass-transfer coefficient was proposed to predict the effective length of the fiber for CO2 absorption. The model also emphasized the significance of membrane wetting when using high concentrations of MEA in the chemical absorption process.

Summary: In Taiwan, the excessive emissions of pollutant gases from over 14 million motorcycles contribute significantly to air pollution in urban areas. In this study, the fine structures and oxidation states of Pt/Pd/Rh/Ce species in washcoat catalysts of motorcycle catalytic converters were investigated. The results showed that using Pt/Rh/Pd/Ce species on ceria/alumina washcoat effectively controlled the emissions of HCs pollutants through CO exclusion. The presence of an oxygen-rich environment facilitated the oxidation of Rh and Pd species, while the oxidation of Pt species was relatively more difficult. The transition metal in the washcoat catalysts was found to be consistent with the La-O distances at approximately 2.49 angstrom.
