Dissociative recombination as primary dissociation channel in plasma chemistry

Journal of Physics: Conference Series, 2009
Molecule formation, surface modification and deposition in plasmas can in first order be described as dissociation in the plasma and association of fragments at the surface. In active plasmas ionization and dissociation by electrons is accompanied by excitation.

The Roasting Marshmallows Program with IGRINS on Gemini South I: Composition and Climate of the Ultrahot Jupiter WASP-18 b

The Astronomical Journal, 2023
We present high-resolution dayside thermal emission observations of the exoplanet WASP-18 b using IGRINS on Gemini South. We remove stellar and telluric signatures using standard algorithms, and we extract the planet signal via cross-correlation with ...

Protonated α-N-Acetyl Galactose Glycopeptide Dissociation Chemistry

Journal of the American Society for Mass Spectrometry, 2022
We recently provided mass spectrometric, H/D labeling, and computational evidence of pyranose to furanose N-acetylated ion isomerization reactions that occurred prior to glycosidic bond cleavage in both O- and N-linked glycosylated amino acid model systems (Guan et al. Phys. Chem. Chem. Phys., 2021, 23, 23256-23266).

The terminator "toy" chemistry test: a simple tool to assess errors in transport schemes [PDF]

Geoscientific Model Development, 2015
This test extends the evaluation of transport schemes from prescribed advection of inert scalars to reactive species. The test consists of transporting two interacting chemical species in the Nair and Lauritzen 2-D idealized flow field. The sources

The Kinetic Monte Carlo Model of the Auroral Electron Precipitation into N₂-O₂ Planetary Atmospheres

Universe, 2022
Auroral events are the prominent manifestation of solar/stellar forcing on planetary atmospheres. They are closely related to the energy deposition by and evolution of planetary atmospheres, and their observations are widely used to analyze the ...

Antiradical Activity of Beetroot (Beta vulgaris L.) Betalains

Molecules, 2021
Flavonoids, phenolic acids, and anthocyanidins are widely studied polyphenolics owing to their antiradical activity. Recently, beetroot dyes have drawn an attention as possible radical scavengers, but scant information can be found on this topic. In this
