Field-ionization threshold and its induced ionization-window phenomenon for Rydberg atoms in a short single-cycle pulse [PDF]
, 2014 We study the field-ionization threshold behavior when a Rydberg atom is ionized by a short single-cycle pulse field. Both hydrogen and sodium atoms are considered. The required threshold field amplitude is found to scale \emph{inversely} with the binding

Ionization behavior of nanoporous polyamide membranes
Proceedings of the National Academy of Sciences of the United States of America, 2020 Significance Novel membrane processes and materials are needed to combat global water scarcity. The advancement of membrane materials for water purification processes such as desalination is hindered by our limited understanding of structure–property ...

Planetary Nebulae and the Ionization of the Interstellar Medium in Galaxies
Frontiers in Astronomy and Space Sciences, 2022 We discuss the role of planetary nebulae and their progeny in galaxy context in terms of ionization of the galaxy interstellar medium. This regards ionized gas outside the disk of spiral galaxies, the diffuse ionized medium in spiral galaxies, and the ...

Intensity-Resolved Above Threshold Ionization of Xenon with Short Laser Pulses [PDF]
, 2014 We present intensity-resolved above threshold ionization (ATI) spectra of xenon using an intensity scanning and deconvolution technique. Experimental data were obtained with laser pulses of 58 fs and central wavelength of 800 nm from a chirped-pulse ...

Precipitation Modification by Ionization [PDF]
Physical Review Letters, 2020 Rainfall is hypothesized to be influenced by droplet charge, which is related to the global circuit current flowing through clouds. This is tested through examining a major global circuit current increase following the release of artificial radioactivity.

Ionization-Gasdynamic Simulations of Wind-Blown Nebulae around Massive Stars
Galaxies, 2022 Using a code that employs a self-consistent method for computing the effects of photo-ionization on circumstellar gas dynamics, we model the formation of wind-driven nebulae around massive stars.

Picosecond ionization dynamics in femtosecond filaments at high pressures [PDF]
, 2017 We investigate the plasma dynamics inside a femtosecond-pulse-induced filament generated in an argon gas for a wide range of pressures up to 60 bar. At higher pressures, we observe ionization immediately following a pulse, with up to a threefold increase

Ionizing and Non-ionizing Radiation [PDF]
, 2017 This chapter describes ionizing radiation and non-ionizing radiation, ways to measure it in the environment, describes the potential health effects from chronic and acute exposures as well as a discussion addressing pregnancy concerns. Background radiation from both sources are described in relation to occupational or public exposure limits and how ...

The physical chemistry of the enigmatic phospholipid diacylglycerolpyrophosphate
Frontiers in Plant Science, 2012 Phosphatidic acid (PA) is a lipid second messenger that is formed transiently in plants in response to different stress conditions, and plays a role in recruiting protein targets, ultimately enabling an adequate response.
