Finite Element Modeling of a Thermoplastic Polyurethane Ball for Rolling Seismic Isolation

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 4, Page 926-946, 10 April 2026.
ABSTRACT The Elastomeric‐Ball Pendulum (EBP) system, which consists of an elastomeric ball rolling on a spherical concrete surface, has been proposed as an isolation system for lightweight structures. Experimental tests have shown that the mechanics of such a rolling ball are remarkably complicated because the vertical load changes the shape of the ...

Material Compatibility of Poly(Ether)urethane 80A With Vaporized Hydrogen Peroxide Sterilization: A Comprehensive Evaluation of Oxidative Stability and Biocompatibility

Journal of Biomedical Materials Research Part A, Volume 114, Issue 4, April 2026.
Hydrogen peroxide reacts with intracellular iron via a Fenton reaction, generating hydroxyl radicals that are consumed within the microbe, causing lethal oxidative damage while minimizing interaction with surrounding materials. ABSTRACT Poly(ether)urethanes (PEUs) are widely used in long term implanted medical devices. Their susceptibility to oxidative

Toward Greener Hybrid Composites: Effect of Wood Powder and Calcium Carbonate on Recycled HDPE With Tyre and MAPE Modifiers

SPE Polymers, Volume 7, Issue 2, April 2026.
Recycled high‐density polyethylene (rHDPE) was reinforced with wood powder (0–25 wt%) and calcium carbonate (5 wt%), modified with ground tyre powder (5 wt%) and maleic anhydride grafted polypropylene (MAPP, 5 wt%). The hybrid filler system demonstrated: Mechanical Enhancement: Tensile strength increased by 25.5%, stiffness by 45%, and tensile modulus ...

4D Biomimetic Wrinkled Porous Textiles via Electrospinning and Melt Electrowriting for Advanced Strain Sensing

Small Structures, Volume 7, Issue 4, April 2026.
A novel 4D fabrication method creates wrinkled, porous textiles mimicking biological tissue mechanics with J‐shaped stress–strain behavior. By combining electrospinning and melt electrowriting, these hybrid materials offer tunable stiffness and pre‐stretching control, enabling seamless integration with diverse tissues. Ideal for wearable strain sensors,

Achilles tenocytes from diabetic and non diabetic donors exposed to hyperglycemia respond differentially to inflammatory stimuli and stretch

Journal of Anatomy, Volume 248, Issue 4, Page 675-688, April 2026.
Scheme depicting the experimental set up of the study. Achilles tendons and tenocytes were isolated from heterozygous (fa/+, non diabetic: non DMT2) and homozygous (fa/fa, diabetic: DMT2) Zucker Diabetic Fatty (ZDF) rats. Tendon degeneration, collagen type 1 alpha 1 chain (COL1A1) and alpha smooth muscle actin (αSMA) expression was determined in rat ...
