Design of an 8‐Channel Transmit 32‐Channel Receive 11.7T Head Coil and Evaluation of SNR Gains

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 4, Page 2004-2018, October 2026.
ABSTRACT Purpose To design and develop an 8‐channel transmit 32‐channel receive 11.7T head coil for the strongest human MRI scanner to date, demonstrate safety, and evaluate signal‐to‐noise ratio (SNR) gains compared to 7T, the most used ultra‐high‐field (UHF) platform.

Role of Binders on the Performance of SnO2‐Based Gas Diffusion Electrodes for Electrochemical CO2 Reduction to Formic Acid

open access: yesChemElectroChem, Volume 13, Issue 18, 19 September 2026.
Highlights Ionomers (PIL1‐d, Nafion, Sustainion XA9 & PTFE) have a significant effect on the performance of SnO2‐based gas diffusion electrodes (GDE) for eCO2RR. PIL1‐d effectively stabilizes SnO2 catalyst nanoparticles in spray‐coating inks and enhances eCO2RR towards formic acid.

CO2 Activation by Small Copper, Cobalt, and Yttrium Oxide Clusters Probed via Infrared Multiple‐Photon Dissociation Spectroscopy

open access: yesChemPhysChem, Volume 27, Issue 17, 14 September 2026.
Infrared multiple photon dissociation spectroscopy is used to study the activation of CO2 on Cu‐, Co‐, and Y‐oxide clusters. While CO2 activation is not possible on cationic clusters, the binding motif on anionic clusters depends on a fine interplay between the nature and energetic location of the molecular orbitals and the charge (oxidation state) on ...

Low‐Complexity Phase–Transition‐Based VO2 Transmissive Reconfigurable Intelligent Surface for Indoor Millimeter‐Wave Communications

open access: yesNanophotonics, Volume 15, Issue 17, 11 September 2026.
We demonstrate a VO2‐based transmissive reconfigurable intelligent surface for indoor millimeter‐wave communication. The TRIS replaces conventional PIN and varactor diodes with geometrically tailored VO2 switches, enabling transmitted phase control through phase‐transition‐based switching.

Mechanically Compliant, Precision‐Porous Brain Implants Reduce the Foreign Body Reaction and Guide Regeneration

open access: yesAdvanced Healthcare Materials, Volume 15, Issue 33, 4 September 2026.
This study explores how the brain responds to implants of different properties. Hydrogels with various mechanical properties and pore sizes were implanted in adult rat brains. It is observed that hydrogels with mechanical property closely matched to the brain and 40 µm pore size elicit a pro‐healing response from the brain by modulating the immune ...
