The Materiality of the Cloggs Cave Rockshelter's Painting, GunaiKurnai Country (East Gipplsland), Southeastern Australia

Archaeometry, EarlyView.
ABSTRACT The materiality of the white pigment motif at the Cloggs Cave rockshelter, near Buchan in GunaiKurnai Country (southeastern Australia), contains details about the cultural and environmental contexts in which the art was created and preserved. Here, we (1) present physicochemical analyses of the pigment composition; (2) explore implications for

Tunable Coplanar Ferroelectric Thin‐Film Microcapacitors for Integration into High‐Power Microwave Systems

Nano Select, Volume 7, Issue 10, October 2026.
Thin‐film ferroelectric microcapacitors are analyzed using full‐wave electromagnetic simulations to establish design rules linking material properties, geometry, and electrical performance. The relationships among ferroelectric permittivity, film thickness, dielectric tunability, and coplanar capacitor geometry are established.

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.
