Summary: This study aimed to improve the stability and bioavailability of EGCG in aqueous solutions and in vivo by preparing EGCG glycosylated arachin nanoparticles and EGCG glycosylated casein nanoparticles. The results showed that the DPPH scavenging activity of the nanoparticles was stable within temperature range of 25-70 degrees Celsius. EGCG enhanced the crosslinking effect of molecular particles in the glycosylation complexes solution. The glycosylated protein nanoparticles were stable to acid-base and enzymolysis in simulated gastrointestinal fluid.

Summary: The potential allergenicity of amandin was reduced by binding it with EGCG using different methods, such as alkaline, free radical, ultrasound-assisted alkaline, and ultrasound-assisted free radical methods. The binding of amandin to EGCG was found to be covalent or non-covalent, and was mainly through cysteine and glutamate residues. This study provides a new method and theoretical basis for developing hypoallergenic almond food.

Summary: This study presents a strategy to tailor soy protein-derived amyloid fibrils (SAFs) into hydrogels using (-)-epigallocatechin-3-gallate (EGCG). EGCG can cleave SAFs and induce the formation of branched chains, leading to gel-like structures. SAFs-EGCG complexes show superior antibacterial activity and are non-toxic to human cells.

Summary: This study investigated the stability and antioxidant capacity of epigallocatechin gallate (EGCG) in cell culture medium DMEM. It was found that EGCG was unstable in DMEM, forming various degradation products over time. Ascorbic acid improved EGCG stability and its antioxidative properties decreased over time, consistent with its degradation.

Summary: This study focuses on estimating repair time and time-dependent availability of gas turbine power plant components and subsystems based on human experience. Fuzzy logic and adaptive neuro-fuzzy inference system were used for simulation and prediction. The Monte Carlo simulation method was utilized to estimate the time-dependent availability for 20 years. The results revealed the critical components in the power plant units and indicated lower availability for the fuel system and lubrication system. The highest availability of 95% was estimated in the 16th year, while the lowest availability of 87% was predicted in the 19th year.

Summary: This study investigates binder evaporation as a significant microscale phenomenon in fluidized bed wet granulation. It models the evaporation of a single droplet, a sessile droplet, and a liquid bridge, taking into account the effects of operational conditions and liquid/particle properties. The results show that higher relative velocity and smaller equilibrium contact angle increase the evaporation rate, while increasing the length of the binder bridge reduces the rupture time.

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 study compared the effects of supercritical carbon dioxide dewatering (SCD) and conventional kiln drying (CKD) at a temperature of 55 degrees C on the dewatering rate, moisture transfer and distribution, shrinkage, and stress characteristics of bamboo strips. The results showed that SCD had a faster dewatering rate and lower shrinkage compared to CKD, but was less effective in reducing drying stress in bamboo.

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.
