Air Quality Field Measurements in Las Vegas: Ozone Formation and Its Sensitivity to NOx and VOCs

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 19, 16 October 2025.
Abstract Las Vegas, Nevada is an urban center in the southwest US where the population is rapidly growing. In Las Vegas, surrounded by the Mojave Desert, biogenic emissions are low, but anthropogenic emissions, especially along the Las Vegas Strip, are a large source of volatile organic compounds (VOC) and nitrogen oxides (NO + NO2 = NOx) from volatile

From Turpentine to (−)‐Menthol: A New Approach

open access: yesChemSusChem, Volume 18, Issue 17, September 1, 2025.
Renewable 3‐carene, which can be obtained from the pulp and paper industrial waste crude sulfate turpentine, is successfully transformed to the aroma compound menthol, utilizing a new, four‐step synthesis route. Heterogeneous hydrogenation, solid acid catalysis, and phase transfer catalysis are utilized under organic solvent‐free conditions, with ...

Secondary organic aerosol 2. Thermodynamic model for gas/particle partitioning of molecular constituents [PDF]

open access: yes, 2002
A model that predicts secondary organic aerosol (SOA) formation based on the thermodynamic equilibrium partitioning of secondary organic oxidation products has been developed for implementation into atmospheric models.

A self-consistent, multi-variate method for the determination of gas phase rate coefficients, applied to reactions of atmospheric VOCs and the hydroxyl radical [PDF]

open access: yes, 2017
Gas-phase rate coefficients are fundamental to understanding atmospheric chemistry, yet experimental data are not available for the oxidation reactions of many of the thousands of volatile organic compounds (VOCs) observed in the troposphere.
