High-temperature rheological properties of amorphous poly-α-olefin/styrene-butadiene rubber composite modified asphalt

open access: yesHecheng xiangjiao gongye, 2023
Asphalt was modified by thermoplastic resin modifier amorphous poly-α-olefin (APAO) and styrene-butadiene rubber (SBR) and APAO/SBR composite modified asphalt was prepared. The basic properties of the composite modified asphalts were tested.

Myrcene‐Based Tailored Co‐Polymers as Active Pharmaceutical Excipients: Bio‐Based Solutions for Mucoadhesive Excipients

open access: yesAdvanced Functional Materials, EarlyView.
Mucoadhesive amphiphilic block and statistical copolymers were synthesized via Reversible Addition–Fragmentation Chain Transfer polymerization from bio‐sourced myrcene and polyethylene glycol methacrylate. The resulting polymers exhibit narrow molar‐mass distributions, high regioselectivity, well‐defined microstructures, and tend to self‐assemble into ...

Low‐Fraction Irregular Inclusions Trigger Large Compression Stiffening in Biopolymer Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
Irregular inclusions at low filler fractions trigger large compression stiffening in biopolymer hydrogels. By promoting contact‐network formation under compression, these inclusions induce non‐affine rearrangements, stretch surrounding fibers, and provide parallel load‐bearing pathways.

Tuning Mechanoreceptor Signaling Enhances the Adjuvant Effect of Biomaterial Vaccines

open access: yesAdvanced Functional Materials, EarlyView.
Matrix stiffness serves as an independent immunological signal in biomaterial vaccines. Stiffer microporous hydrogel vaccines enhance dendritic cell maturation and migration to draining lymph nodes, promote T follicular helper cell expansion through Yap/Taz signaling, and increase antigen‐specific antibody production.

Chamber‐Specific Decellularized Extracellular Matrices Differentially Modulate Cardiomyocyte Subtypes to Drive Engineered Heart Tissue Development and Function

open access: yesAdvanced Healthcare Materials, EarlyView.
Chamber‐specific decellularized extracellular matrices (ECMs) were developed, preserving native proteomic profiles of ventricular and atrial myocardium. These innate biochemical cues differentially modulate cardiomyocyte subtypes to drive engineered heart tissue development and function, highlighting the importance of incorporating regional ECM cues in

A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

open access: yesAdvanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.
