Summary: This study aimed to improve the aqueous solubility of 4-hydroxycoumarin by using deep eutectic solvents (DESs). The results showed that the solubility of 4-hydroxycoumarin significantly increased with higher DES concentration and temperature. The Wilson model provided the best correlation for aqueous solutions containing different DES compositions, and the dissolution process of 4-hydroxycoumarin was found to be endothermic. Quantum mechanical Density functional theory (DFT) calculations confirmed the spontaneous formation of DESs and DES/4-hydroxycoumarin complexes through hydrogen bonding interactions.

Summary: New polymeric pipes have been used to overcome the challenges posed by metal pipes in gas transmission, such as corrosion and leakage. This study investigates the diffusivity and potential leakage of methane and ethane gases in glass-reinforced epoxy (GRE) composite using diffusion and solubility cells. The results demonstrate that the diffusivity of both gases increases with temperature, while gas solubility decreases. Furthermore, novel correlations for estimating gas diffusion coefficient and mass flow rate have been developed based on experimental data.

Summary: The dissolution and diffusion properties of hydrogen in transition metal carbides were studied using first-principles calculations. It was found that hydrogen tends to occupy the trigonal site in these carbides, with the bonding interaction between hydrogen and the nearest-neighbor carbon atom playing a key role in stability. Temperature-dependent solubility and diffusion coefficients were determined, with hydrogen showing poorer solubility and difficulty in migration in TMC compared to pure vanadium. Additionally, a linear relationship was observed between diffusion barrier and hydrogen solution energy in transition metal carbides.

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. The reaction parameters and catalyst stability were also investigated.
