Robust β‐myrcene block copolymer elastomeric vitrimers

open access: yesPolymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Multifrequency Multiparameter Magnetic Resonance Elastography Applied to an In Vivo Porcine Model for Assessing Portal Hypertension

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
Portal hypertension, a critical complication in chronic liver disease, has long relied on invasive hepatic venous pressure gradient measurement for definitive diagnosis. This study establishes that multifrequency three‐dimensional magnetic resonance elastography (3D‐MRE) can noninvasively quantify portal pressure, with splenic stiffness and loss ...

Dual‐Crosslinked Hydrogels With Enhanced Mechanical and Thermal Properties

open access: yesJournal of Polymer Science, EarlyView.
An illustrative depiction of a dual‐crosslinked polymer network achieved with dynamic crosslinkers (blue) and covalent crosslinkers (red). ABSTRACT Creating artificial skin requires materials that can mimic the mechanical properties and structural integrity of natural skin.

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.

Relation of Bulk‐to‐Shear Loss Factors in Viscoelastic Auxetic Metamaterials

open access: yesphysica status solidi (b), EarlyView.
This article examines the dynamic behavior of isotropic auxetic viscoelastic materials, highlighting how negative Poisson's ratios affect energy dissipation, damping, and the interplay between bulk and shear moduli. By extending established viscoelastic theories to the auxetic range, it defines bound limits and underscores how dynamic Poisson's ratio ...
