Summary: Lithium-sulfur (Li-S) batteries are considered promising next-generation batteries due to their theoretical energy density. However, the practical application is hindered by the sluggish conversion reaction from Li2S2 to Li2S. This study establishes a theoretical model to understand the Li2S2 conversion mechanisms. The effects of electrode potential are accurately described, and it is predicted that Fe single atom catalysts can provide the highest electrode potential. Analysis on electronic structures confirms the electrocatalysis activity comes from the chemical bonds between S and transition metal atoms. This work unveils the Li2S2 conversion mechanisms and opens new exploration possibilities for redox reactions in Li-S batteries and other energy storage systems.

Summary: In this study, a Fe-doped NiO nanoarray interlayer-modified Pd/Ni foam (Pd/Fe-NiO/NF) was synthesized as an efficient cathode catalyst for electrocatalytic hydrodechlorination (ECH) of 2,4-dichlorophenoxyacetic acid (2,4-D). The Fe-NiO nanoarray on the nickel foam increased the electrochemically active surface area of the electrode and improved the dispersion of catalytically active Pd nanoparticles (Pd NPs). Introducing the Fe-NiO interlayer facilitated water ionization and atomic H* generation, providing more atomic H* for the ECH process. Compared to the conventional Pd/NF electrode, the Pd/Fe-NiO/NF showed enhanced dechlorination efficiency and reduced Pd requirement, with excellent reusability and stability.

Summary: Non-conventional amines are being researched worldwide to overcome the limitations of traditional amines like MEA and MDEA. Adequate process and thermodynamic models are crucial for understanding the applicability and performance of these amines in CO2 absorption, but studies on process modeling for these amines are limited. This study used rate-based modeling and Deshmukh-Mather method to model CO2 absorption by DETA solution in a packed column, validated the model with experimental data, and conducted a sensitivity analysis of mass transfer correlations. The study also compared the CO2 absorption efficiency of DETA solution with an ionic solvent [bmim]-[PF6] and highlighted the importance of finding optimum operational parameters for maximum absorption efficiency.

Summary: The utilization of smart water in EOR operations has gained attention, but more research is needed to understand the complex mechanisms involved. This study investigated the interfacial tension between smart water and crude oil, considering factors such as salt, pH, asphaltene type, and aged smart water. The results revealed that the hydration of ions in smart water plays a key role in its efficacy, with acidic and basic asphaltene acting as intrinsic surfactants. The pH also influenced the interfacial tension, and the aged smart water's interaction with crude oil depended on asphaltene type, salt, and salinity.

Summary: In this study, high-performance solid catalysts based on phosphotungstic acid (HPW) supported on Zr-SBA-15 were synthesized and evaluated for the one-pot conversion of furfural (FUR) to γ-valerolactone (GVL). The catalysts were characterized using various techniques, and the ratio of HPW and Zr was found to significantly affect the selectivity of GVL. The HPW/Zr-SBA-15 (2-4-15) catalyst exhibited the highest GVL yield (83%) under optimized reaction conditions, and it was determined that a balance between Bronsted acid sites (BAS) and Lewis acid sites (LAS) was crucial for achieving higher catalytic performance.
