Our research in this field has improved existing theoretical methods for treating the Stark effect of photoionization processes in Rydberg atoms. From an experimental viewpoint, photoionization in an ...

"Every day, light from the sun causes photoionization in the ionosphere, causing ionospheric layers to move, combine or separate." From sunrise onward, this causes the ionosphere to expand ...

"We have combined, for the first time, the optical constants of HAC, obtained from laboratory experiments, with models of ...

Korista uses photoionization models to explore the physical conditions of these regions, with the goal of understanding the role of quasars in the evolution of galaxies over cosmic time.

This is because corrosive substances can poison or otherwise deactivate or interfere with VOC/photoionization detection (PID) meter sensors. If this happens, your VOC/PID meter is rendered useless. Q: ...

SCRANTON, Pa. — Preparing for the solar eclipse was an all-day affair at the University of Scranton on Monday. While some students were just watching, others were working hard on research.

Choices include flame ionization, atomic emission, electron capture, photoionization, flame photometric, chemiluminescence spectroscopy, and nitrogen phosphorous. Thermal conductivity and flame ...
