Energetic microdomains and the vascular control of neuronal and muscle excitability: Toward a unified model

The Journal of Physiology, EarlyView.
Abstract figure legend The capillary–mitochondria–ion channel (CMIC) axis scales structural resources to match functional workload. (Left) In settings of restricted energetic capacity (e.g. cortical neurons), sparse capillary networks and modest mitochondrial pools set a lower energetic ceiling, sufficient to support phasic, low‐workload excitability.

Coaxial Dipole Array With Switching Transmit Sensitivities for Ultrahigh Field MRI

Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3608-3615, June 2026.
ABSTRACT Purpose To investigate dipole antennas with electronically switchable transmit field patterns to improve flip angle homogeneity in ultra‐high field MRI. Methods Reconfigurable dipole elements that could produce two distinct electronically switchable B1+ field profiles were conceptualized and constructed.

Structural Characterization of Cardiac Free‐Running Purkinje Fibers Using Inhomogeneous Magnetization Transfer (ihMT): A Proof of Concept MRI‐Histology Approach

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
The cardiac Purkinje network is essential for synchronized ventricular activation but remains difficult to visualize with conventional MRI due to limited structural contrast. This study demonstrates that inhomogeneous magnetization transfer imaging provides enhanced contrast that differentiates free‐running Purkinje fibers, Purkinje‐Myocardial Junction,

Electromagnetic Quasinormal Modes: A Foundational Framework for Describing Fano Resonances of Extinction Spectra

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
An ab initio electromagnetic framework links quasinormal modes to Fano resonances in extinction spectra. Analytical expressions for the Fano asymmetry and intensity parameters are derived from overlap integrals, enabling rapid spectral reconstruction and physical interpretation.

Harnessing Interfacial Field Localization in Hexagonal GaP Mie Resonators

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
Сharacterization of Mie modes in self‐assembled GaP nanowires grown by MBE in vertical and horizontal configurations. The hexagonal cross‐section suppresses higher‐order modes while preserving dominant low‐order modes with spectral shifts. Simulations and dark‐field spectroscopy confirm the diameter‐dependent tunability.

4D Printing of Multimaterial Flexible Magneto‐Active Polymers

Advanced Materials Technologies, Volume 11, Issue 9, 6 May 2026.
Magneto‐active polymers are 3D‐printed with tunable mechanical and magnetic properties using both superparamagnetic and hard ferromagnetic fillers. Nano‐CT imaging reveals the spatial distribution of particles within the matrix. Programmable magnetization patterns and soft, flexible architectures enable responsive actuation, offering exciting ...
