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 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.

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.

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 ...

High-order harmonic spectroscopy in an ionized high-density target

Frontiers in Physics, 2022
We use high-order harmonic spectroscopy to study ionization dynamics in a macroscopic target with tunable density, spanning over six orders of magnitude.

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 ...

Doubly and Triply Differential Cross Sections for Single Ionization of He by Fast Au⁵³⁺ Using a Multi-Body Quasiclassical Model

Atoms, 2020
A multi-body multi-center quasiclassical model was used to determine doubly- and triply-differential cross sections following single ionization in 3.6 MeV/amu Au53+ + He collisions.
