Impact of acidity and surface-modulated acid dissociation on cloud response to organic aerosol [PDF]

open access: yesAtmospheric Chemistry and Physics
Acid dissociation of the organic aerosol fraction has the potential to impact cloud-activating properties by altering aqueous-phase H+ concentrations and water activity but is currently overlooked in most atmospheric aerosol models.

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

open access: yesThe 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 ...

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

open access: yesUniverse, 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 ...

Quantum Dynamics of Exciton Transport and Dissociation in Multichromophoric Systems.

open access: yesAnnual review of physical chemistry (Print), 2021
Due to the subtle interplay of site-to-site electronic couplings, exciton delocalization, nonadiabatic effects, and vibronic couplings, quantum dynamical studies are needed to elucidate the details of ultrafast photoinduced energy and charge transfer ...

Hypervelocity Richtmyer–Meshkov instability [PDF]

open access: yes, 1997
The Richtmyer-Meshkov instability is numerically investigated for strong shocks, i.e., for hypervelocity cases. To model the interaction of the flow with non-equilibrium chemical effects typical of high-enthalpy flows, the Lighthill-Freeman ideal ...

CO2 Dissociation using the Versatile Atmospheric Dielectric Barrier Discharge Experiment (VADER)

open access: yesFrontiers in Physics, 2014
Dissociation of CO2 is investigated in an atmospheric pressure dielectric barrier discharge (DBD) with a simple, zero dimensional (0-D) chemical model and through experiment.

Antiradical Activity of Beetroot (Beta vulgaris L.) Betalains

open access: yesMolecules, 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
