This study assesses the impact of grape juice-based alginate or chitosan edible coatings, followed by UVC treatment, on the preservation of post-harvest quality of Red Globe grapes. Coated grapes were stored at 5 °C for 28 days, and their physical, chemical, microbiological, and sensory properties were assessed during the storage period. Films were prepared with grape juice using alginate and chitosan and exposed to 32.

Natural materials with highly oriented heterogeneous structures are often lightweight but strong, stiff but tough and durable. Such an integration of diverse incompatible mechanical properties is highly desired for man-made materials, especially weak hydrogels which are lack of high-precision structural design. Herein, we demonstrate the fabrication of hierarchically aligned heterogeneous hydrogels consisting of a compactly crosslinked sheath and an aligned porous core with alignments of nanofibrils at multi-scales by a sequential self-assembly assisted salting out method.

This work presents the effect of Polyhydroxybutyrate nanospheres (PHB-NSs) on the bacterial activity of plasmonic nanoparticles (NPs). The PHB-NSs were used as a substrate for the metal-NPs. Silver and gold NPs in colloidal solution were synthesized by chemical reduction, while PHB-NSs were synthesized by a physical method.

Air pollution significantly contributes to the global burden of respiratory and cardiovascular diseases. While single source/compound studies dominate current research, long-term, multi-pollutant studies are crucial to understanding the health impacts of environmental aerosols. Our study aimed to use the first air-liquid interface (ALI) aerosol exposure system adapted for long-term in vitro exposures for ambient air in vitro exposure.

The traditional understanding of brain function has predominantly focused on chemical and electrical processes. However, new research in fruit fly (Drosophila) binocular vision reveals ultrafast photomechanical photoreceptor movements significantly enhance information processing, thereby impacting a fly's perception of its environment and behaviour. The coding advantages resulting from these mechanical processes suggest that similar physical motion-based coding strategies may affect neural communication ubiquitously.
