A systematic study of 12 ferric and ferrous Kβ X-ray emission spectra (XES) is presented. The factors contributing to the Kβ main line and the valence to core region of the spectra are experimentally ...

Based on time-series photometry from three different telescopes, an international team of astronomers has performed a ...

Based on tunable diode laser absorption spectroscopy (TDLAS) technique, a novel optical method is proposed to detect dissolved methane in transformer oil. Oil samples with fault gases are prepared and ...

Abstract: Identical weak optical fiber Bragg grating (FBG) arrays can be fabricated in-line on a draw tower using the phase mask technique. On the FBG arrays, some grating spectrum distortions, for ...

In the hunt for exoplanets, many seek out habitable worlds. There's comfort in discovering planets that remind us of ...

The search for extraterrestrial life has long gone back and forth between scientific curiosity, public fascination and ...
