Improve the Thermal Conductivity, Insulation Performance and Mechanical Properties of Silicone Rubber by Constructing EG‐PDA‐Cu Hybrid Nanoparticles

Journal of Polymer Science, EarlyView.
In this work, a novel expanded graphite‐supported nano‐copper polydopamine composite was designed and synthesized. The procedure involved first modifying EG via a mussel‐inspired technique to deposit a polydopamine coating, after which Cu2+ ions were reduced to immobilize copper nanoparticles onto the EG‐PDA substrate.

Scalable Manufacturing of Amino Acid‐Based Piezoelectric Biocrystal Films

Small, EarlyView.
This work presents a continuous manufacturing strategy for glycine‐PVA piezoelectric films through dynamically controlled crystallization. This stable and industrially viable strategy offers significant potential for mass production of piezoelectric biocrystal films and biocompatible devices.

Quantitative Analysis of Topographic Crosstalk in DART‐ESM Arising from Feedback‐Loop‐Delay‐Induced Contact Stiffness Variations in Battery Materials

Small Methods, EarlyView.
Interpretation of Dual AC Resonance‐Tracking Electrochemical Strain Microscopy (DART‐ESM) signals is complicated by topography‐induced artifacts that distort measured responses. Using silicon with artificial trench structures as a reference, this study quantifies artifact magnitude and demonstrates that Cooling Cross‐Section Polishing (CCP) effectively

Left Bundle Branch Area Pacing Reverts Electromechanical Window Negativity to a Similar Extent as Biventricular Pacing

Pacing and Clinical Electrophysiology, EarlyView.
BiVP = biventricular pacing; CRT = cardiac resynchronization therapy; EMW = electromechanical window; LBBAP = left bundle branch area pacing; QAoC = Time interval from the onset of the QRS complex to the center of the aortic valve closure artifact; QT = QT interval measured by tangent method.

Determining properties of human‐induced pluripotent stem cell‐derived cardiomyocytes using spatially resolved electromechanical metrics

The Journal of Physiology, EarlyView.
Abstract figure legend In this study, we use human‐induced pluripotent stem cell‐derived cardiomyocyte (hiPSC‐CM) experiments and computational modelling to identify the mechanism of action of drug compounds. In the hiPSC‐CM experiments, optical measurements of cell collections are recorded in the baseline case and after drug exposure.

Elucidating the cellular determinants of the end‐systolic pressure‐volume relationship of the heart via computational modelling

The Journal of Physiology, EarlyView.
Abstract figure legend Using a multiscale computational model of left ventricular electromechanics, we investigated how sarcomere dynamics influence the end‐systolic pressure‐volume (ESPV) relationship in ejecting beats compared to isovolumetric beats.

Insights from electromechanical simulations to assess omecamtiv mecarbil efficacy in heart failure

The Journal of Physiology, EarlyView.
Abstract figure legend Impact of Omecamtiv Mecarbil (OM) on in‐silico models of heart failure. A mathematical electromechanical model of human ventricular tissue is used to simulate the effects of OM in heart failure with reduced ejection fraction (HFrEF).

Repolarization adaptation to rapid change in heart rate in human models – a review

The Journal of Physiology, EarlyView.
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

Electromechanical modelling and simulation of human‐induced pluripotent stem cell‐derived cardiomyocytes predict drug‐induced contractility effects

The Journal of Physiology, EarlyView.
Abstract figure legend A study described in this paper describes a new tool for hiPSC‐CM electromechanical behaviour simulations using mathematical modelling. The model enables in silico assays making drug testing quick, comprehensive and accurate. New hiPSC‐CM models can be used as a platform to integrate in vitro and in silico findings.

Revealing the Hidden Stress Field and Its Thermal Input Dependence in Femtosecond Laser–Processed Silicon Photonic Chip Substrates via Weak Measurement

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
A novel noncontact method based on weak value amplification enables high‐sensitivity stress mapping of femtosecond laser processed silicon photonic chip substrates. It converts microscale stress into the birefringent phase via the photoelastic effect and reads it out with weak measurement, achieving a 0.37‐kPa detection limit.
