Solid-state NMR spectroscopy on complex biomolecules [PDF]

, 2010
Biomolecular applications of NMR spectroscopy are often merely associated with soluble molecules or magnetic resonance imaging. However, since the late 1970s, solid-state NMR (ssNMR) spectroscopy has demonstrated its ability to provide atomic-level ...

Spectral Ghost Imaging for Ultrafast Spectroscopy

IEEE Photonics Journal, 2022
We experimentally demonstrate ghost imaging in the frequency domain based on frequency speckle patterns as references. Our method is suitable for measuring the spectrum of ultrafast signals with high repetition rates.

Power scaling of tunable, narrowband, non-resonant PPLN optical parametric oscillators

Journal of the European Optical Society-Rapid Publications
We review our recent achievements with narrowband, nanosecond, non-resonant optical parametric oscillators based on periodically-poled LiNbO3, which are pumped at 1064 nm and emit close to degeneracy in the near-IR part of the spectrum between 1860 and ...

Intermediate Resistive State in Wafer‐Scale Vertical MoS2 Memristors Through Lateral Silver Filament Growth for Artificial Synapse Applications

Advanced Functional Materials, EarlyView.
In MOCVD MoS2 memristors, a current compliance‐regulated Ag filament mechanism is revealed. The filament ruptures spontaneously during volatile switching, while subsequent growth proceeds vertically through the MoS2 layers and then laterally along the van der Waals gaps during nonvolatile switching.

Compliant mechanical response of the ultrafast folding protein EnHD under force

Communications Physics, 2023
Exhibiting low-energy (un)folding barriers and fast kinetics, ultrafast folding proteins are enticing models to study protein dynamics. The authors use single molecule force spectroscopy AFM to capture the compliant behaviour hallmarking the dynamics of ...

Operando Tracking of Oxygen‐Vacancy Dynamics and Negative Capacitance in Ca‐Doped BiFeO3

Advanced Functional Materials, EarlyView.
Operando electrochemical impedance spectroscopy, combined with electrocoloration, enables a direct correlation between real‐space ionic redistribution and the corresponding frequency‐domain electrical response. In lateral Ca‐doped BiFeO3 devices, time‐resolved impedance snapshots capture the evolution from bulk‐dominated mixed conduction to an ...
