Summary: In order to improve the removal efficiency of carbonyl sulfide (COS) and develop a green desulfurization process, a novel ternary desulfurization system was constructed with TBEE as catalyst, PEG200 as promoter, and H2O as reactant. The absorption performance of COS can reach 95% under atmospheric pressure and ambient temperature with an optimal volume proportion of 3:3:4 (TBEE:PEG200:H2O, V/V/V). The study established the first-order hydrolysis reaction kinetic of the desulfurization system and COS from 298 to 338 K, and demonstrated that TBEE and PEG200 enhance gas-liquid mass transfer as gas phase transfer agents.

Summary: This study investigates the use of foaming agents to foam cathode-ray-tube panel glass and explores the impact of carbon type, MnxOy, and furnace atmosphere on foaming effect and physical properties of foams. The results show that the best foaming effect is achieved with MnO2 in an oxidizing atmosphere, while oxidation of carbon is facilitated by Mn3O4 in an oxygen-free atmosphere, leading to the formation of CO and open porosity. The study demonstrates the potential for improving thermal insulation by decreasing density in closed-porous samples produced with carbon black and Mn3O4.

Summary: A study explored a ternary solvent extraction system containing a water-soluble beta-cyclodextrin derivative for the selective extraction of glabridin from Glycyrrhiza glabra. The optimal extraction system consisted of a sulfobutylether-beta-cyclodextrin aqueous phase and an n-octanol: n-hexane organic phase. Multi-stage centrifugal fractional extraction under ideal conditions yielded glabridin with a purity of 95% and a yield of 97%. This technique provides an effective, environmentally-friendly and cost-effective method for separating glabridin from the crude extract.

Summary: The conductor-like screening model was used to identify ILs for efficient extraction of PFOA, with [P6,6,6,14][Piv] found to be a suitable IL due to its strong chemical attraction for PFOA and beneficial physicochemical properties. Experimental results showed [P6,6,6,14][Piv] could remove >99.9% of PFOA in aqueous solution, but emulsification issues limited the removal rate to 80-91% at low PFOA/IL molar ratios. Washing the IL with 1% NaOH partially regenerated its ability to extract PFOA, allowing for reuse with a slightly decreased removal rate per cycle.

Summary: Polyvinyl butyral (PVB) waste, collected from end-of-life vehicles and post-consumer building laminated glass, is a valuable polymeric material that can be recycled. A lack of appropriate recycling techniques results in a significant amount of PVB waste being buried in landfills each year. This study focuses on purifying PVB from contamination by dissolving post-consumer polymeric materials in single and binary organic solvents. Experimental measurements and optimization of the dissolution time of PVB were conducted. The study found that PVB dissolves faster using a binary solvent (2-propanol + ethyl acetate) compared to pure 2-propanol. The obtained PVB solutions can be widely used as glues for various materials or transparent paint additives.

Summary: Cold thermal energy storage, particularly in the form of passive thermal protection, is becoming increasingly important globally. This study presents three eutectic Phase Change Materials (ePCMs) composed of n-alkanes, which provide passive temperature control automatically at around 4 degrees C and are chemically neutral. The study investigates the solid-liquid equilibrium (SLE) and solid-liquid-liquid equilibrium (SLLE) of various ePCMs, and analyzes the design and predictive capabilities of eutectic mixtures. Furthermore, the study explores the improvement of the thermal conductivity of paraffins with the addition of nanomaterials and demonstrates the feasibility of creating a long-lasting composite material with enhanced thermal conductivity.

Summary: A new association model, CPA-MHV1, combining the SRK equation of state with the CPA equation based on Michelsen's improved Huron-Vidal mixing rule, is developed. The model is used to investigate the vapor-liquid equilibrium of binary mixtures involving CH4, CO2, and H2O, as well as ternary mixtures containing NaCl. The results show that considering the solvation between CO2 and H2O yields the best performance, while CH4 with a pseudo-association scheme has the highest comprehensive prediction performance.

Summary: In this study, the solid-liquid coexistence curve for water was developed using coarse-grained mW and machine-learned ML-BOP water models. The ML-BOP model exhibited lower densities, a broader density-temperature hysteresis loop, and higher free energy compared to the mW model. The pressure dependence fusion curve for both models aligned with previous literature. This analysis demonstrates that the free energy method accurately captures the solid-liquid transformation and the thermodynamic melting point of water.

Summary: A generalized theoretical framework is introduced for multicomponent reactive nonuniform systems, combining the modified and generalized Cahn-Hilliard equation with a chemical kinetics model. The framework allows for the modelling and investigation of the combined reaction and diffusion in reactive liquid-liquid systems. It is found that for reacting mixtures with much smaller reaction rates than diffusion rates, the mixture will remain in phase equilibrium upon reaction and the interfacial chemical reaction will not affect the overall system dynamics, which are only influenced by the kinetics of the bulk phases.
