Polyvinyl alcohol

open access: yes
Polyvinyl alcohol (PVA) is one of the main exploited Water-Soluble Polymers (WSPs), from packaging production to biomedical purposes. However, despite its widespread use, there still seems to be some controversy regarding its chemical safety.

Beyond the Camera: Epidermal Sensor Platforms for Intelligent Facial Expression Recognition and Interactive Human Monitoring

open access: yesAdvanced Intelligent Systems, EarlyView.
Skin‐conformal epidermal sensors enable camera‐free intelligent facial monitoring by converting facial deformation and muscle activity into electrical signals through piezoresistive, capacitive, electrophysiologic, and self‐powered mechanisms. Coupled with artificial intelligence (AI), these platforms support facial expression recognition, human ...

Multifunctional PVC/PVA‐ZnO Nanocomposites: Bridging Dielectric Response and Antibacterial Activity for Active Packaging Applications

open access: yesJournal of Applied Polymer Science, EarlyView.
PVC and PVA polymer blends are studied as a function of frequency at room temperature to find the composition that gives the AC conductivity. The blend that has 75% PVC and 25% PVA is chosen as the matrix. Then 10% ZnO nanoparticles are added for food packaging. The change, in conductivity is used as a sign of activity and food freshness. ABSTRACT This

Comparative Performance of Poly(Vinyl Alcohol)/Chitosan Hydrogels Reinforced With Kraft Lignin and Kraft Lignin Nanoparticles

open access: yesJournal of Applied Polymer Science, EarlyView.
The use of kraft lignin and kraft lignin nanoparticles in poly(vinyl alcohol)/chitosan hydrogels was comprehensively compared. The results showed that a higher loading of lignin nanoparticles than bulk kraft lignin could be incorporated while maintaining favorable hydrogel properties, leading to improved overall performance. ABSTRACT The development of

Development of Biocatalysts Based on Lipase B From Candida antarctica Immobilized on Magnetic Poly(Styrene‐Co‐Divinylbenzene) for Application in Esterification Reactions

open access: yesJournal of Applied Polymer Science, EarlyView.
Magnetic biocatalysts can be recovered from high‐viscosity reaction media, such as those used in esterification, via magnetic attraction, thereby streamlining the bioprocess and reducing costs. This work builds on prior studies by providing additional data on how particle morphology influences immobilization parameters and by further exploring ...

Distribution of doublecortin in the developing retina of birds: A comparative analysis

open access: yesThe Anatomical Record, EarlyView.
Abstract The avian retina presents an elegant and highly accessible model for investigating the spatial and temporal dynamics of neurogenesis within the central nervous system. In recent years, the microtubule cytoskeleton has emerged not merely as a structural scaffold, but as a dynamic regulator of the transition of a morphologically homogeneous pool

Micro‐ and nanoplastics in gastrointestinal disorders: Mapping the translational gap between exposure, biomonitoring, and pathogenic mechanisms

open access: yesBMEMat, EarlyView.
This review highlights critical “translational gaps” in understanding micro‐ and nanoplastics impacts on gastrointestinal diseases, bridging exposure, detecting, and mechanistic toxicology. Abstract Micro‐ and nanoplastics (MNPs) have become pervasive environmental contaminants with increasing evidence linking them to adverse health outcomes.

Exosome‐mimetic vesicle‐encapsulated multi‐responsive antibacterial hydrogel core‐shell microneedle patch promotes scarless healing of infected wounds

open access: yesBMEMat, EarlyView.
The core‐shell microneedle patch VP@FNV‐CuO2‐MN was fabricated by encapsulating n‐CuO2 in a moderately crosslinked PVA/CMCS/Borax4 hydrogel shell and VP‐loaded fibroblast membrane nanovesicles (VP@FNV) in a highly crosslinked PVA/CMCS/Borax6 hydrogel core. Upon application to an infected wound, the acidic microenvironment triggers Fenton‐like reactions
