The Iseult Coil, a Hybrid RF Coil for the First Human Brain Images at 11.7 T: Receive Performance Comparison With a Twin Coil at 7 T

NMR in Biomedicine, Volume 39, Issue 10, October 2026.
Our 8‐Tx/32‐Rx coil is based on two rows of transceiver microstrips intertwined with receive‐only loops. Comparison of the intrinsic SNR at 7 and 11.7 T leads to a 2.2 ratio for the human brain, and 2.75 for a 16‐cm agar sphere, translating into α = 1.5 and 1.95 in the B0α$$ {B}_0^{\alpha } $$‐SNR model, respectively.

Photofluidization of Azobenzene‐Based Smart Materials: Fundamental Mechanisms, Structural Classifications, and Surface Patterning Applications

SmartMat, Volume 7, Issue 5, October 2026.
Azobenzene materials possess reversible photofluidization, promising for surface patterning. This review summarizes state‐of‐the‐art advances in azo‐material photofluidization, including photoisomerization mechanisms, molecular/polymer structural categories, emerging patterning applications, remaining challenges and future outlooks.

Nanosecond, Nanometer Movies of MEMS/NEMS Dynamics in a Standard SEM Using Time‐Tagged Secondary Electrons

Small Methods, Volume 10, Issue 19, 7 October 2026.
For the observation of micromechanical devices, a fast imaging technique with high temporal resolution is needed. Here, we demonstrate that a standard scanning electron microscope can be converted into a time‐resolving instrument using a fast detector and a time‐to‐digital converter.

A Regional Intercomparison of Ice Sheet Mass Balance Estimates of the Northwest Greenland Ice Sheet

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 10, October 2026.
Abstract Changes in ice sheet mass manifest as changes in ice flow, ice thickness, and gravitational attraction. These parameters can be measured from space and used to track Greenland's contribution to sea level rise independently from each other. While an excellent level of agreement between these satellite techniques has been demonstrated at the ice

Determination of Earth's Static Gravity Field Using Quantum Gravity Satellites at Very Low Earth Orbit

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Very Low Earth Orbit (VLEO) satellite platforms and quantum‐optical sensing technologies may provide new observation approaches for improving Earth's static gravity field models. This study conceptually assesses their potential contribution through a two‐tier closed‐loop simulation framework.

Estimation of Mesoscale Momentum Flux Frequency Spectra in the Mesosphere and Lower Thermosphere Using Multistatic Specular Meteor Radar Wind Fields

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract A spectrally resolved observational methodology is introduced to estimate mesoscale momentum flux frequency spectra in the mesosphere and lower thermosphere (MLT). The method is applied to four‐dimensional wind fields reconstructed with the physics‐informed neural network approach called the Hydrodynamic Point‐wise Environment Reconstructor ...

Short‐Wavelength Seafloor Topography From SWOT Marine‐Gravity Products Using a Transformer U‐Net With Hybrid Loss

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Classical satellite altimetry has limited sensitivity to seafloor topography at wavelengths shorter than about 150 km, leaving short‐wavelength structure poorly constrained away from ship tracks. The Surface Water and Ocean Topography (SWOT) mission improves gravity recovery at these scales.

A Machine Learning Framework for Retrieving Atmospheric Composition and the Associated Averaging Kernels From a Geostationary Hyperspectral Infrared Sounder

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Geostationary hyperspectral infrared sounders provide hourly observations of the atmospheric composition. However, the conventional optimal estimation method (OEM)‐based retrieval algorithm requires computationally expensive radiative transfer calculations and inverse modeling, making it difficult to monitor in real time. This study presents a
