Summary: One of the basic principles of green chemistry is to find less harmful alternative solvents. This study provides density data for two hydrophilic deep eutectic solvents (choline chloride + ethylene glycol or glycerol) and two hydrophobic eutectic solvents (camphor + thymol or menthol) at various pressures and temperatures. The Tait equation of state and the PC-SAFT equation of state are used to correlate the data and calculate derived properties. The results show that the hydrophilic solvents are more compact and exhibit abnormal thermal behavior.

Summary: In this study, gluten/zein (G/Z) blends were electrospun with acetic acid as a solvent. The effects of zein content on the morphology, structure and properties of assembled gluten nanofibers were investigated. The presence and distribution of both proteins in the G/Z nanofibers were confirmed. The results showed that the diameter and surface morphology of the nanofibers varied with the zein content. The alpha-helix structure, crystallinity and hydrophobicity increased with increasing zein to gluten ratio. DSC analysis revealed a single glass transition temperature in the G/Z nanofibers, indicating the miscibility of the blend. The flexibility of the fibers increased as the amount of zein decreased.

Summary: The study demonstrates that hydrophobic deep eutectic solvents (DESs) are efficient in eliminating hydrophilic VOCs due to their high absorption capacity and favorable gas-to-liquid mass transfer. Among the DESs explored, the one containing thymol and decanoic acid in a 1:1 molar ratio exhibits the highest acetone absorption capacity, showing the key role of hydrogen bonding interaction in achieving superior solubility of acetone in DESs. The absorbed acetone can be easily removed from the DESs, making the process economically and ecologically beneficial for hydrophilic VOC elimination.

Summary: Nanofluid has attracted attention as a heat transfer fluid due to its superior thermal conductivity and rheological properties. In this study, a novel one-step preparation method was developed using Cu(OH)(2) as a precursor and deep eutectic solvents (DESs) as dispersing medium to overcome the poor stability and short liquid range associated with traditional nanofluids. The as-prepared nanofluid exhibited extraordinary static stability for at least two months without sedimentation and wide liquid range due to the in-situ formed Cu2O nanoparticles in DESs under microwave irradiation. The nanofluid's structural analysis and thermophysical properties were comprehensively studied, revealing that the thermal conductivity was slightly affected by the presence of Cu2O nanoparticles at low mass fractions. Importantly, the DESs-based nanofluid demonstrated promising photothermal conversion with the addition of 0.1 wt% Cu2O nanoparticles. This study provides an important approach for preparing nanofluids with high static stability.

Summary: This study aims to develop a biocompatible scaffold for dermal applications using thermally annealed electrospun propolis-loaded zein nanofibers. The results show that nanometric size ribbon-like fibers ranging from 420 to 575 nm can be obtained due to the favorable interactions between zein and propolis. When loaded into fibers, propolis is gradually delivered to cells and exhibits no cytotoxicity. The findings provide promising prospects for the development of propolis-loaded nanofiber patches for wound healing.

The chemical structure of PEICT ENM was confirmed using FTIR and XPS spectroscopy, while the hydrophobic nature and excellent fibroblast adhesion were demonstrated through a water contact angle test. Overall, the results suggest the potential of PEICT ENMs as a biomaterial.
