Holographic Mapping of Orbital Angular Momentum using a Terahertz Diffractive Optical Neural Network

open access: yesAdvanced Intelligent Discovery, EarlyView.
A compact six‐layer diffractive optical neural network enables direct recognition and spatial mapping of terahertz (THz) orbital angular momentum (OAM) beams. Fabricated by 3D printing, the system distinguishes nine OAM modes and their superpositions with high fidelity, good efficiency, and low crosstalk, offering a scalable solution for THz ...

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 ...
