Water‐driven dispersible fiber electrode arrays for position‐dependent intracardiac electrophysiological recording

FlexMat, EarlyView.
Abstract Intracardiac electrophysiological recording plays an essential role in identifying abnormal cardiac electrical activity and guiding arrhythmia diagnosis and treatment planning. A key challenge for minimally invasive intracardiac electrodes is to combine reliable transvascular delivery with stable and compliant endocardial contact.

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...

Multiscale Modeling of Hole Damage Evolution During Dynamic Installation of Interference Bushings in CFRP

Polymer Composites, EarlyView.
Multiscale modeling for dynamic installatioin. ABSTRACT The dynamic installation of metal interference bushings has demonstrated significant potential for improving the mechanical performance of carbon fiber‐reinforced polymer (CFRP) joints. However, the underlying mechanisms governing the remaining life enhancement remain insufficiently understood ...

Adhesive Protein Nanoparticles Control Emulsion Properties via Tunable Interdroplet Linking

Small, EarlyView.
In this study, pea protein nanoparticles were probed for their ability to link emulsion droplets. Experiments across multiple length scales showed that the nanoparticles form shear‐resistant links via bridging interactions from the thin film between droplets.
