Thermal Ionization [PDF]

Mathematical Physics, Analysis and Geometry, 2004
In the context of an idealized model describing an atom coupled to black-body radiation at a sufficiently high positive temperature, we show that the atom will end up being ionized in the limit of large times. Mathematically, this is translated into the statement that the coupled system does not have any time-translation invariant state of positive ...

Ionized Keplerian Disks Demonstrating Interplay Between Strong Gravity and Magnetism [PDF]

Entropy
Using the dynamics of charged test particles, we study the interplay of extremely strong gravitational and magnetic fields acting on ionized Keplerian disks.

Double-slit photoelectron interference in strong-field ionization of the neon dimer [PDF]

Nature Communications, 2018
Wave-particle duality is an inherent peculiarity of the quantum world. The double-slit experiment has been frequently used for understanding different aspects of this fundamental concept.

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.

Ionization and structural properties of mRNA lipid nanoparticles influence expression in intramuscular and intravascular administration

Communications Biology, 2021
Lipid Nanoparticles (LNPs) are used to deliver siRNA and COVID-19 mRNA vaccines. The main factor known to determine their delivery efficiency is the pKa of the LNP containing an ionizable lipid.

Electron-Impact Ionization of Heavy Atoms Using the Time-Dependent Close-Coupling Method

Atoms, 2021
The time-dependent close-coupling method has been recently applied to calculate electron-impact direct ionization cross sections for the Kr, W, and Pb atoms. An overview is presented for these three heavy neutral atom systems.

Separation of ions with the same charge to mass ratio from a collision experiment [PDF]

Journal of the Serbian Chemical Society, 2000
Some atomic collision experiments lead to ions having identical q/m ratio, as well as average velocity, so that standard electric and magnetic analyzers are not able to identify them separately.

Experimental Evaluations of the Impact of an Additive Oxidizing Electronic Air Cleaner on Particles and Gases

Pollutants, 2022
Electronic air cleaning (EAC) technologies have garnered significant attention for use in buildings. Many EAC technologies rely on the addition of reactive constituents to indoor air to react with gas-phase compounds, enhance particle deposition, and/or ...

Light Dark Matter Search with Ionization Signals in XENON1T. [PDF]

Physical Review Letters, 2019
We report constraints on light dark matter (DM) models using ionization signals in the XENON1T experiment. We mitigate backgrounds with strong event selections, rather than requiring a scintillation signal, leaving an effective exposure of (22±3) tonne ...
