ABSTRACT Recent analyses of nebular spectra have resulted in discrepant abundances from CNO forbidden and recombination lines. We consider independent methods of determining ion abundances for ...

The absorption process of an emitter close to a plasmonic antenna is enhanced due to strong local electromagnetic (EM) fields. The emission, if resonant with the plasmonic system, re-radiates to the ...

the more infrared radiation it gives out in a given time the greater the proportion of emitted radiation is visible light There are no known objects that are perfect at absorbing or emitting all the ...

Coblentz left no stone unturned – he measured spectra in transmission and in reflection. He even measured the emission ...

In a new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022.210036, authors from the Laser Engineering Group in the School of Engineering at the University of Liverpool, Liverpool, ...

Hexagonal transition metal dichalcogenide monolayers (h-TMDCs MLs) form a new class of two-dimensional (2D) materials with extreme dimensional confinement effects 1,2,3,4,5,6,7,8,9,10,11. In ...

Scientists have been all aflutter since several space-based detectors picked up a powerful gamma-ray burst (GRB) in October 2022—a burst so energetic that astronomers nicknamed it the BOAT (Brightest ...

Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...

Highly enhanced UV absorption and light emission of monolayer WS2 through hybridization with Ti2N MXene quantum dots and g-C3N4 quantum dots This work represents a significant advancement in the field ...
