First In Vivo 23Na Human Imaging at 10.5 T Using a Combined Sodium‐Proton Transceiver Body Array

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2429-2441, April 2026.
ABSTRACT Purpose To demonstrate the first in vivo human 23Na MRI at 10.5 T using a novel dual‐tuned transceiver body array and to evaluate a self‐gating approach for respiratory motion compensation, focusing on renal imaging. Methods A custom‐built eight‐channel 23Na‐loop 1H‐dipole transceiver array was designed, constructed, and characterized.

RF‐Shielding of Laser‐Cut Venous Stents: Calculations, Simulations, and Experiments

Magnetic Resonance in Medicine, Volume 95, Issue 4, Page 2331-2344, April 2026.
ABSTRACT Purpose To develop an analytical model of the RF‐shielding of laser‐cut venous stents for different orientations and stent geometries. Methods Laser‐cut venous stents are modeled as a grid composed of circular and rectangular loops. As these loops are orthogonal they shield different components of the transmit RF field.

Smart and Flexible Optical Solar Reflectors for Passive Radiative Cooling Regulation in Space Using a W:VO2 Metasurface

Nanophotonics, Volume 15, Issue 3, 12 February 2026.
Passive regulation of thermal management in space relies on engineered radiative coatings that can vary their emissivity with temperature. Here a smart and flexible solution is presented combining a W:VO2 metasurface with a low‐emissivity solar reflector. This highly durable first‐surface coating survives space qualification tests and offers attractive

Diameter Dependence of Light Absorption in GaAs Nanowires Evidenced by Photoluminescence Spectroscopy

Advanced Optical Materials, Volume 14, Issue 5, 2 February 2026.
Photoluminescence spectroscopy is introduced as a qualitative method to probe light absorption in highly phase‐pure GaAs nanowire arrays and single nanowires, for which direct absorption measurements are challenging. Using defect‐line saturation and the exciton‐to‐plasma transition as indicators for the density of photogenerated charge carriers, a ...
