Bio‐Based Polyurethanes: Mechanical Performance, Structure–Property Relationships, and Future Directions

Journal of Polymer Science, EarlyView.
This review examines bio‐based polyurethanes from renewable feedstocks, focusing on structure‐property relationships governing mechanical performance. It analyzes reinforcement strategies, benchmarks against petrochemical counterparts, and explores future directions, including non‐isocyanate routes and circular economy integration for sustainable high ...

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

physica 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 ...

Roughness Measurements at Small and Uneven Surfaces of Ceramic Foam Filters

Surface and Interface Analysis, EarlyView.
ABSTRACT This study investigated the possibility of roughness characterization of ceramic foam filters using a laser scanning microscope, examining the influence of magnification, measured area, cutoff wavelength (λc), measured roughness parameter, and position within the ceramic foam on the measured roughness data. Firstly, the effect of magnification
