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.

Analysis of Eigenvalue Clustering Leads to Optimal Scaling in Numerical Radiative Transfer

Numerical Linear Algebra with Applications, Volume 33, Issue 5, October 2026.
ABSTRACT We consider a multidimensional polychromatic radiative transfer (RT) problem, accounting for scattering processes in a general form, that is, anisotropic (dipole) scattering with partial frequency redistribution. Given a discrete ordinates (SN$$ {S}_N $$) discretization, we report the corresponding matrix structures, depending on the model and

Superstrong and Tough Biomimetic Lignin‐Based Hydrogel Enabled by Self‐Diffusion Driven Strategy for Self‐Powered Human Dynamic Healthcare Monitoring

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Biomass‐based hydrogels are widely regarded as ideal substrates for self‐powered wearable sensors. However, the practical applications of hydrogels are commonly limited by their inherent low strength and toughness, which restrict their capacity to withstand repeated stretching, bending and other mechanical loads arising from human motion in ...

Amphiphilic Motif Triggers Microheterogeneity in Low‐Melting Mixtures

Small Structures, Volume 7, Issue 10, October 2026.
Alkylated cholinium iodides are synthesized and mixed with ethylene glycol, resulting in low‐melting mixtures (LMMs). Ammonium alkylation induces amphiphilicity and drives nanoscale segregation into charge‐rich and charge‐poor domains. Combined spectroscopic, scattering, and computational analyses reveal how headgroup alkylation and counterion effects ...

Fifty Years Later: Revisiting Viking 2 Seismic Signals Through InSight

AGU Advances, Volume 7, Issue 7, October 2026.
Abstract For nearly 50 years, the origin of the candidate seismic signals recorded by Viking 2 remained unresolved because of limited instrumental sensitivity, onboard observation, data compression, and the absence of Martian seismic context. Here we reconstruct the Viking seismic workflow and reinterpret the two Viking candidate events, recorded on ...
