We report on spectral observations of the night sky in the band around 900 Å where the emission line in the Sciama model of radiatively decaying massive neutrinos would be present. The data were obtained with a high resolution, high sensitivity spectrometer flown on the Spanish MINISAT satellite. The observed emission is far less intense than that expected in the Sciama model. Subject headings:...
A facile one-step synthesis of CdTe quantum dots (QDs) in aqueous solution by atmospheric microwave reactor has been developed using 3-mercaptopropionic acid reduction of TeO2 directly. The obtained CdTe QDs were characterized by ultraviolet-visible spectroscopy, fluorescent spectroscopy, X-ray powder diffraction, multifunctional imaging electron spectrometer (XPS), and high-resolution transmis...
Line emissions from both silicon (Si) and boron (B) impurity ions introduced by a single tracer-encapsulated solid pellet (TESPEL) containing hexaboride (SiB6) powders were successfully observed using the extreme ultraviolet (EUV) spectrometer charge-exchange spectroscopy (CXS) technique in Large Helical Device. The CXS diagnostic shows clearly that hollow radial profile of fully ionized B impu...
Dual Comb Spectroscopy proved its versatile capabilities in molecular fingerprinting different spectral regions, but not yet the ultraviolet (UV). Unlocking this window would expand to electronic energy structure of matter.This will access prime triggers photo-chemical reactions with unprecedented resolution. In research article, we discuss milestones marking way first UV dual comb spectrometer...
