Mechanistic investigation of ionization suppression in electrospray ionization

Journal of the American Society for Mass Spectrometry, 2000
We show results from experiments designed to determine the relative importance of gas phase processes and solution phase processes into ionization suppression observed in biological sample extracts. The data indicate that gas phase reactions leading to the loss of net charge on the analyte is not likely to be the most important process involved in ...

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.

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 ...

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.

The Atmospheric Influence on Cosmic-Ray-Induced Ionization and Absorbed Dose Rates

Universe, 2023
When high-energy particles originating from space penetrate the atmosphere, they may interact with atoms and molecules, initiating air showers composed of secondary and tertiary particles propagating towards the ground.

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.

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
