Position Over Composition: Positional Isomerism Enables Encapsulation‐Independent Intrinsic Stability in a Conjugated Polymer

Small, EarlyView.
Repositioning side chains (para→meta) provides a composition‐invariant handle to program conjugated‐polymer chain geometry. The resulting worm‐like, kink‐suppressed conformation delivers >5× higher intrinsic photostability and enhanced resistance to energetic particle damage.

Three‐Dimensional Piezoelectric Fibrous Constructs for Muscle Regeneration

Small, EarlyView.
This study fabricates 3D piezoelectric PHBV scaffolds to enhance muscle regeneration by systematically tuning electrospinning parameters. Introducing porosity yields a 25‐fold enhancement in the effective piezoelectric coefficient (d33). A highly effective d33 signal, activated by cellular tension and fiber deformation, significantly improves myogenic ...

Regression‐based models for the torsional stiffness reduction factor in reinforced concrete beams under combined torsion and shear

Structural Concrete, EarlyView.
Abstract This paper presents a regression‐based methodology to estimate the Torsional Stiffness Reduction Factor (TSRF) of reinforced concrete beams under combined torsion and shear. A numerical database of 6816 samples was generated using the Combined Action Softened Truss Model (CA‐STM) implemented in Python, considering design guidelines prescribed ...

Strong ground motion and structural damage in the 2023 Kahramanmaraş earthquakes: A comparative case study of numerical predictions and field observations

Structural Concrete, EarlyView.
Abstract On February 6, 2023, southeastern Türkiye was struck by two catastrophic earthquakes (Mw: 7.7 and Mw: 7.6) along the East Anatolian Fault Zone, causing extensive structural failures and significant loss of life. This study evaluates the seismotectonic characteristics of the sequence, analyzes strong ground motion data against the Turkish ...

Damping ratio of reinforced concrete walls under limited damage from shaking table test and data‐driven modeling

Structural Concrete, EarlyView.
Abstract Accurate estimation of the damping ratio is critical for evaluating floor response spectra and equipment seismic demands in nuclear power plant structures. This study investigates the elastic damping ratio of reinforced concrete walls under limited damage states through shaking table tests and data‐driven modeling.
