Summary: In order to improve the extraction yield of bioactive compounds from L. rivularis stems, sequential supercritical extraction experiments were carried out in three stages using CO2 and ethanol-modified-CO2. The use of cosolvent and increased pressure resulted in higher total yield of extract and target compounds compared to one-stage extraction. Experiment 4 achieved the highest extraction yields of extract (6.29 g/kg d.s.), terpenes (699.9 mg/kg d.s.), flavonoids (741.9 mg/kg d.s.), and alkaloids (6.22 mg/kg d.s.).

Summary: In this study, the potential use of subcritical water hydrolyzed soybean husks as a biosorbent for the removal of basic Red 9 dye was evaluated. The biosorbent showed efficient uptake of the dye at a pH of 8.0, and the Langmuir model described the biosorption equilibrium well. The thermodynamic parameters indicated that the biosorption process was spontaneous and endothermic. The biosorption equilibrium was reached in 60 minutes, and the diffusivity values were calculated using the Linear Driving Force model.

Summary: In this study, four polythiourethane films with different types of polyols and isocyanates were synthesized, characterized, and foamed. The results showed that the type of isocyanate greatly influenced the crystallinity and stiffness of the polymers, while the type of polyol modified the FT-IR spectra and the decomposition curve of the material with temperature. Furthermore, the choice of isocyanate also affected the properties of the foams obtained from the polymeric material.

Summary: This study experimentally assessed the hydrodynamic characteristics of supercritical-pressure R134a in a horizontal circular tube. It was found that the hydrodynamic characteristic curve of R134a under supercritical pressure does not have a negative-slope region but a transition region. The transition region becomes more evident with increasing heat flux, while it weakens with increasing pressure and inlet temperature. Moreover, the onset of the transition region shifts in the direction of high mass flow rate with increasing heat flux.

Summary: This research aimed to valorize brewery spent grain (BSG) using subcritical water hydrolysis (SWH) modified by six different natural deep eutectic solvents (DES) and determining their bipotentialities. The findings showed that BSG hydrolysates obtained through DES-induced SWH contained high levels of sugars, proteins, flavonoids, phenolic compounds, and essential amino acids. The hydrolysates also demonstrated antimicrobial activities, and the presence of bioactive compounds was confirmed through FT-IR analysis. This comprehensive profiling of bioactive compounds from BSG using DES-mediated SWH can contribute to the efficient valorization of BSG for industrial purposes.
