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.

Reconfigurable Terahertz Multi‐Harmonic Dual‐Combs
Nanophotonics, Volume 15, Issue 17, 11 September 2026.Terahertz dual‐comb spectroscopy requires precise control of repetition frequencies. A reconfigurable dual‐comb system is realized on a single self‐detected quantum cascade laser platform, where harmonic order serves as a new tuning parameter. Switching among fundamental and harmonic states enables flexible multi‐heterodyne down‐conversion without ...
