Novel Recyclable Hierarchical Carbon Fiber/Epoxy Composites: Preserving Fiber Length and Orientation Using Elium

open access: yesPolymer Composites, EarlyView.
Schematic illustration of a hierarchical recycling approach that preserves reinforcing fiber orientation. ABSTRACT Current recycling methods for polymer matrix composites produce short, unoriented carbon fibers, limiting their use to intermediate‐strength applications.

Bio‐Based Multilayer Composites Based on Blended Electrospun Fibers and Luffa Cylindrica for Enhanced Low‐Frequency Noise Absorption

open access: yesJournal of Polymer Science, EarlyView.
Bio‐based multilayer composites consisting of Luffa Cylindrica and electrospun microfibers exhibit enhanced sound absorption, shifting peak performance towards lower frequencies. The multilayer configuration improves acoustic wave dissipation, providing a tunable and sustainable solution for urban and traffic‐related noise mitigation.

Revealing Intrinsic Functionalization, Structure, and Photo‐Thermal Oxidation in Hexagonal Antimonene

open access: yesSmall, EarlyView.
Cross‐sectional electron microscopy reveals that antimonene hexagons exhibited inner defects and protective organic functionalization against oxidation. Temperature and power‐dependent Raman spectroscopy on varying thicknesses of FLA hexagons show that thinner flakes (<20 nm) exhibited a blueshift and intensity decrease, contrasting with the redshift ...

Influence of Temperature on the Reliability of Graphene‐Based Ozone Sensors

open access: yesSmall, EarlyView.
The reliability and stability of inkjet‐printed graphene flake sensors are evaluated. Stress assessments take place in ozone‐rich environments and at elevated temperatures, with the observation of a change in resistance. Surface‐sensitive techniques serve to investigate the failure and degradation mechanisms of printed graphene.
