Summary: This study investigates the effect of electrospun nylon-6 nanofibrous membranes (NFMs) on the concentration of bitter compounds and antioxidants in grapefruit juices during dead-end filtration processes. The results show that NFMs selectively retain low molecular weight antioxidants at early filtration stages and remove bitter glycosylated phenolics at a variable ratio depending on membrane thickness. Filtration of fresh grapefruit juice using NFMs reduces flavanones associated with immediate bitterness and completely removes limonin, the compound responsible for persistent bitterness. NFMs have potential in selectively reducing bitter terpenoids and glycosylated flavonoids from grape juice in the production of beverages.

Summary: Covalent adaptable networks (CANs) combine the advantages of traditional thermosets and thermoplastics, and have attracted significant attention. The dynamics of reversible covalent bonds and polymer chain mobility in CANs are crucial for their self-healing and reprocessing properties. In this study, an ionic liquid was introduced into dimethylglyoxime-urethane (DOU)-based CANs to regulate reversible bond dynamics and polymer chain mobility. The ionic liquid catalyzed dynamic DOU bond exchange and increased the mobility of polymeric chains by breaking hydrogen bonds. This study also demonstrated the potential of using ionic CANs for high-performance multifunctional wearable electronics responsive to various stimuli.

Summary: An intrinsic flame retardant copolyester based on PET and thermo-tropic liquid crystalline polymer (PET/TLCPx) was designed and prepared via a simple and efficient one-step melt copolymerization. PET/TLCPx exhibits excellent thermal stability, fire resistance, and non-dripping properties due to the formation of a denser char layer and the increase of complex viscosity and molecular weight during combustion. These high-performance copolyesters are highly valuable for high-end applications with strict requirements for fire safety and thermal stability.

Summary: The reasons behind the occurrence of a second/end peak heat release rate (PHRR) during wood combustion under radiative heating were investigated. The type of rear material, wood thickness, char progression, and its microstructure, as well as moisture content/transport in spruce wood, were found to affect the second/end PHRR. The intensity of the second/end PHRR with insulating Kaowool was significantly higher than with conducting steel, suggesting that the rear material boundary condition plays a role in determining the heat losses and temperature of the specimen, which in turn influences the pyrolysis rate and the occurrence of the second/end PHRR. The presence of cracks in char during the second/end PHRR resulted in wider char growth and affected the overall heat release.

Summary: The surge towards a sustainable future in the construction industry requires the use of bio-based insulation materials as an alternative to conventional ones for improving energy efficiency in structures. The features of bio-based insulation materials, including their thermal conductivities, moisture buffering value, fire performance, and life cycle evaluations are examined. It is clear that pre- and post-treatment of the bio-based materials used for insulation materials optimize their properties. Life cycle analysis reveals a significant reduction in global warming potential (GWP) compared to conventional foams, and producing bio-based insulation materials on a larger scale will further decrease the net GWP. The article proposes the implementation of policies that will promote the commercialization of bio-based insulation materials.

Summary: In this study, we proposed a general strategy to facilitate tissue repair by modulating endogenous electric fields using nonadjacent wireless electrotherapy. We developed a 3D printed entirely soft and bioresorbable triboelectric nanogenerator-based stimulator which has biomimetic mechanical properties similar to those of soft tissue. The feasibility of constructing an electrical double layer with tissue for nonadjacent wireless electrotherapy was demonstrated and significant improvements in tissue repair were observed in the treated groups compared to the control group.

Summary: In this study, different coating systems, including solvent-based epoxy and water-based acrylic resins, were evaluated as alternatives to chromate coatings for their potential to avoid Cr(VI) toxic hazards. The corrosion resistance of the coatings on galvanized ST12 steel plates was investigated and the impact resistance of polymeric coatings with different binders and pigments was evaluated. The results showed that epoxy coatings completely peeled from the substrate, while water-based acrylic coatings only had few small cracks. Overall, this study provides insights into the development of an inexpensive and environmentally friendly acrylic coating as a promising replacement for chromate coatings.
