Strukturelle und chemische Dynamik von Cu/NiO/Cu(100)‐Oberflächen während der CO2‐Hydrierung

Angewandte Chemie, EarlyView.
Dynamische Segregation als Designprinzip für Cu–Ni‐Katalysatoren. Operando‐LEEM/XPEEM verfolgt Reduktions‐, Umstrukturierungs‐ und Oberflächensegregationsprozesse in Cu‐verkapselten NiO‐Inseln auf Cu(100) während der CO2‐Hydrierung. ZUSAMMENFASSUNG Das Verständnis der dynamischen Umstrukturierung bimetallischer Katalysatoren unter Reaktionsbedingungen ...

Vanadium dioxide thin films integrated with printed circuit board enables low-cost, reconfigurable millimeter-wave devices

Communications Engineering
Millimeter-wave switches are essential for reconfigurable and adaptive communication systems, yet current solutions often face trade-offs between performance, scalability, and cost. Here we present a scalable, high performance and cost-effective approach

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

Angewandte 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

Reshaping the phonon energy landscape of nanocrystals inside a terahertz plasmonic nanocavity

Nature Communications, 2018
Here the authors show that the dipole-active phonon resonance of semiconducting nanocrystals can be hybridized by a strongly concentrated terahertz vacuum field of a plasmonic nanocavity, thus achieving strong plasmon–phonon coupling even in the absence ...

Ion-retention properties of graphene oxide/zinc oxide nanocomposite membranes at various pH and temperature conditions

Scientific Reports
Laminar graphene oxide (GO) is a promising candidate material for next-generation highly water-permeable membranes. Despite extensive research, there is little information known concerning GO's ion-sieving properties at high acidic/basic pH and ...

Direct Observation of Propagating Spin Waves in a Spin Hall Nano-Oscillator. [PDF]

Adv Mater
By combining frequency injection locking with time‐resolved scanning transmission x‐ray microscopy (TR‐STXM), the authors image the real‐time magnetization dynamics of a spin Hall nano‐oscillator (SHNO) for the first time. Their results reveal richer dynamics than previously reported and challenge existing assumptions regarding the radiation hardness ...
