Anharmonicity and the IR Emission Spectrum of Neutral Interstellar PAH Molecules.

open access: yesJournal of Physical Chemistry A, 2022
The characteristics of the CH stretching and out-of-plane bending modes in polycyclic aromatic hydrocarbon molecules are investigated using anharmonic density functional theory (DFT) coupled to a vibrational second-order perturbation treatment taking ...

Study of the lighting characteristics of Uniel retrofit LED lamps

open access: yesVestnik MGTU, 2023
The paper considers the photometric characteristics of LED retrofit lamps produced by the Russian-Chinese company Uniel: Uniel LED-G45-6W/4000K, Uniel LED-A60-8W/6500K, and Uniel LED-A60-9W/4000K, designed to replace traditional incandescent bulbs ...

Metabolomics of Pseudomonas aeruginosa Treated by Atmospheric-Pressure Cold Plasma

open access: yesApplied Sciences, 2021
With increasing drug resistance of Pseudomonas aeruginosa, a new sterilization method is needed. Plasma has been shown to be an effective method of sterilization, but no researchers have studied the effect of plasma on bacterial metabolism. In this paper,

The Electron Spectrum in 3C 279 and the Observed Emission Spectrum [PDF]

open access: yesThe Astrophysical Journal, 2003
The emission mechanisms of the blazar 3C 279 are studied by solving the kinetic equations of electrons and photons in a relativistically moving blob. The gamma-ray spectral energy distribution (SED) is fitted by inverse Compton scattering of external photons.

Influence of fluorescent pigments on the spectral characteristics of luminous coated fabrics

open access: yesMaterials Research Express, 2021
In recent years, luminous coated fabrics based on SrAl _2 O _4 : Eu ^2+ , Dy ^3+ luminescent materials have attracted more attention. However, due to the single emission color of SrAl _2 O _4 : Eu ^2+ , Dy ^3+ luminescent materials, the application of ...

Evidence for Atmospheric Cold-trap Processes in the Noninverted Emission Spectrum of Kepler-13Ab Using HST/WFC3 [PDF]

open access: yes, 2016
We observed two eclipses of the Kepler-13A planetary system, on UT 2014 April 28 and UT 2014 October 13, in the near-infrared using Wide Field Camera 3 on the Hubble Space Telescope.

Ultra-narrow room-temperature emission from single CsPbBr3 perovskite quantum dots

open access: yesNature Communications, 2022
Semiconductor quantum dots have long been considered artificial atoms, but despite the overarching analogies in the strong energy-level quantization and the single-photon emission capability, their emission spectrum is far broader than typical atomic ...

NEAR-INFRARED EMISSION SPECTRUM OF WASP-103B USING HUBBLE SPACE TELESCOPE/WIDE FIELD CAMERA 3 [PDF]

open access: yes, 2016
We present here our observations and analysis of the dayside emission spectrum of the hot Jupiter WASP-103b. We observed WASP-103b during secondary eclipse using two visits of the Hubble Space Telescope with the G141 grism on Wide Field Camera 3 in ...

Energy Spectrum of Acoustic Emission Signals in Complex Media [PDF]

open access: yesЖурнал нано- та електронної фізики, 2017
A model of the energy spectrum of acoustic emission signals in complex structures with internal degrees of freedom is proposed. On the basis of the computational experiment of X-ray diffraction data, a quantum mechanical calculation of the applicability ...

THE SPECTRUM OF ISOTROPIC DIFFUSE GAMMA-RAY EMISSION BETWEEN 100 MeV AND 820 GeV [PDF]

open access: yesAstrophysical Journal, 2014
The γ-ray sky can be decomposed into individually detected sources, diffuse emission attributed to the interactions of Galactic cosmic rays with gas and radiation fields, and a residual all-sky emission component commonly called the isotropic diffuse γ ...
