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 ...

Amentoflavone, a Preferentially TGF‐β Receptor 1 Inhibitor, Alleviates Cardiac Remodeling and Dysfunction Through Modulating the TGF‐β/Smad and MAPK Signaling Pathways

Phytotherapy Research, EarlyView.
Amentoflavone, a preferentially TGF‐ββ receptor 1 inhibitor, attenuates transverse aortic constriction (TAC)‐triggered cardiac hypertrophy, fibrosis, and dysfunction by suppressing downstream Smad and MAPK signaling cascades in cardiomyocytes and cardiac fibroblasts.

Press Hardening for Sustainable Lightweight Chassis Design in Heavy‐Duty Vehicles: A Material Performance and Life Cycle Assessment Approach

steel research international, EarlyView.
The article explores how high‐strength steels and press hardening revolutionize lightweight chassis design for heavy‐duty vehicles. It reveals that press hardened steels combined with shot peening can cut weight by up to 34% and reduce environmental impact by 21%–32%.

The clashing of in situ and pre‐cast technologies—Western trends and local traditions in concrete engineering shaping shell construction in 20th‐century Hungary

Structural Concrete, EarlyView.
Abstract After a blossoming pre‐World War II (WWII) period, the concrete construction industry in then‐socialist Hungary existed in a relative isolation from the Western World during the mid‐20th century. In this paper, we focus on the body of work of one of the then newly established state‐owned design offices, IPARTERV, to show how the isolation ...

Modeling the response of UHPC shear‐critical beams: Integrating nonlinear finite element analysis and artificial neural network

Structural Concrete, EarlyView.
Abstract An analytical framework suited for the analysis of shear‐critical ultra‐high performance concrete (UHPC) members is presented. The numerical methodology utilizes a nonlinear finite element analysis formulation integrated with an artificial neural network (ANN) that characterizes the UHPC tension response based on its mix design. In addition, a
