Direction of Arrival Estimation in Terahertz Communications using Convolutional Neural Networks

open access: yes
We demonstrate an approach to accurately estimating the Direction of Arrival (DoA) in terahertz communications using Convolutional Neural Networks (CNNs). Quasi-random patterns are generated with a frequency-diverse antenna which is deliberately designed

The Part and the Whole: Field‐Dependent THz‐EPR Spectroscopy Probes Lattice‐Dependent Electronic Structure in Iron(II) Spin Crossover

open access: yesAngewandte Chemie International Edition, EarlyView.
THz‐EPR spectroscopy provides direct access to the low‐lying electronic structure and spin–phonon coupling in iron(II) spin crossover (SCO) complexes. Quantification of the high‐spin fraction (γHS$\gamma _{\text{HS}}$) and subtle shifts in magnetic transitions reveal the influence of the surrounding lattice and enable discrimination between microscopic

Readily Accessible bTurea‐Derived Nitroxide Polarizing Agents for Dynamic Nuclear Polarization: bcTCOOKs and bcTmols

open access: yesChemistry – A European Journal, EarlyView.
Two families of bTurea‐derived biradicals, bcTmols and bcTCOOKs, were prepared as polarizing agents for dynamic nuclear polarization (DNP)‐enhanced NMR through short and efficient synthetic routes. The best‐performing biradical, bcTCOOK‐M2, containing two methyl groups on the urea bridge, provided signal enhancements of up to ∼220 at 14.1 T and 100 K ...
