Resonance broadening due to particle scattering and mode coupling in the quasi-linear relaxation of electron beams

, 2014
Of particular interest for radio and hard X-ray diagnostics of accelerated electrons during solar flares is the understanding of the basic nonlinear mechanisms regulating the relaxation of electron beams propagating in turbulent plasmas. In this work, it

Oxygen Evolution Electrocatalysts with Trinuclear, Mixed‐Valence Iron Motifs on Electronically Aligned Carbon Dots

Advanced Functional Materials, EarlyView.
Trinuclear iron oxo‐bridged catalytic ensembles stabilized by aspartic‐acid‐derived carbon dots provide an effective platform for alkaline oxygen evolution. Mixed‐valence charge balancing, inner‐sphere charge transport, and work‐function alignment within the N/O‐rich carbon framework promote cooperative Fe‐site chemistry and efficient OER ...

Photonic spin hall shift control at the Doppler broadening dielectric medium

Ain Shams Engineering Journal
This paper theoretically investigates the coherent manipulation of the photonic spin hall shift in a four-level dielectric medium. The light beam interacts with cavity having four-level dielectric medium under the Doppler broadening effect.

Proton Magnetic-Resonance Study of Cycloheximide-Ribosome Interactions

, 1990
Cycloheximide-ribosome interactions from sensitive and resistant organisms were studied by proton magnetic resonance spectroscopic techniques. The two methyl resonances of cycloheximide upon interaction with ribosomes from Saccharomyces cerevisiae showed

Misalignment effects in magnetic resonance

, 1973
By means of a theoretical approach recently developed by Pegg and Series (1970, 1973), the consequences of misalignment of the rotating field in magnetic resonance are investigated.

Mechanisms of Nonuniform Line Broadening [PDF]

, 1995
When the spin relaxation time of paramagnetic impurities at different magnetic sites differs by orders of magnitude then instead of resonance line broadening, rather a decay of the line amplitude is expected.

Multidimensional‐Encoded High‐Fidelity Spectrometers With a Floating‐Base Bipolar Junction

Advanced Functional Materials, EarlyView.
A floating‐base bipolar junction photodetector enables multidimensional spectral encoding through synergistic gate‐ and drain‐bias modulation of interfacial barrier matching. The resulting complementary spectral responses form a diverse, weakly correlated response matrix, enabling robust and high‐fidelity spectral reconstruction even at sub‐nanoampere ...
