The Opacity Project: R-Matrix Calculations for Opacities of High-Energy-Density Astrophysical and Laboratory Plasmas

Atoms
Accurate determination of opacity is critical for understanding radiation transport in both astrophysical and laboratory plasmas. We employ atomic data from R-Matrix calculations to investigate radiative properties in high-energy-density (HED) plasma ...

Axial H-bonding Solvent Controls Inhomogeneous Spectral Broadening, Peripheral H-bonding Solvent Controls Vibronic Broadening: Cresyl Violet in Methanol [PDF]

The dynamics of the nuclei of both chromophore and its condensed phase environment control many spectral features, including the vibronic and inhomogeneous broadening present in spectral lineshapes.

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

Advanced Materials, EarlyView.
This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

Self-broadening in Balmer line wing formation in stellar atmospheres [PDF]

, 2000
Details of a theory of self-broadening of hydrogen lines are presented. The main features of the new theory are that the dispersive-inductive components of the interaction (van der Waals forces) have been included, and the resonance components have been ...

Observation of asymmetric spectrum broadening induced by silver nanoparticles in a heavy-metal oxide glass

, 2011
We demonstrate experimentally and support by a theoretical analysis an effect of asymmetric spectrum broadening, which results from doping of silver nanoparticles into a heavy-glass matrix, 90(0.5WO3-0.3SbPO4-0.2PbO)-10AgCl.

Alloying‐Controlled Tuning of Interfacial Spin‐Orbit Interaction and Magnetic Damping in Crystalline FeCo Thin Films Grown on GaAs(001)

Advanced Materials, EarlyView.
The interfacial spin‐orbit interaction in single‐crystalline Fe1−xCox thin films grown on GaAs(001) can be continuously tuned via alloying. Using spin‐orbit ferromagnetic resonance, the authors find that the interfacial spin‐orbit fields exhibit a nonmonotonic dependence on Co concentration, with a minimum at 20% Co. ABSTRACT The discovery of intrinsic

Optomechanical fluorescence tuning in doped polymer thin films

Results in Materials
We report optomechanical fluorescence tuning of organic fluorophores in PMMA polymer thin films induced by optically driven radiation pressure. Low-frequency modulation of the optical pressure generates mechanical vibrations in the film, leading to ...

Multi‐Li+ Coordination for Superior Room‐Temperature Ionic Conductivity in PEO Solid Electrolytes

Advanced Materials, EarlyView.
A phosphonate‐functionalized polycarboxylate ether (P‐PCE) is introduced into PEO electrolytes to induce multi‐Li+ ions coordination, which effectively dissociates lithium salts, liberates Li+ from the strong chelation by PEO chains, and promotes fast Li+ hopping between adjacent coordination sites. Simultaneously, this design establishes dynamic, high‐

A comparative study of spectral line broadening used to determine the temperature and copper number density in an arc-heated air plasma [PDF]

, 1984
An examination is made of detailed spectral line broadening in an attempt to determine whether the simplified broadening approach of A. A. Boiarski (Air Force Flight Dynamics Laboratory) is sufficient in evaluating the temperature and copper number ...

Measurement of the pressure-broadening coefficient of NO by saturation spectroscopy of LMR

, 2000
This paper presents a method for the determination of the pressure-broadening coefficient of 15N16O by 14N16O. The hyperfine-structure-resolved spectral lines of NO were obtained with an intracavity laser magnetic resonance spectrometer via Lamb dips ...
