Wildfires emit significant amounts of pollutants that degrade air quality. Plumes from three wildfires in the western U.S. were measured from aircraft during the Studies of Emissions and Atmospheric Composition, Clouds and ...

Land and atmospheric initial conditions of the Weather Research and Forecasting (WRF) model are often interpolated from a different model output. We perform case studies during NASA's SEAC4RS and DISCOVER-AQ Houston airborne ...

Chemical models must correctly calculate the ozone formation rate, P(O3), to accurately predict ozone levels and to test mitigation strategies. However, air quality models can have large uncertainties in P(O3) calculations, ...

The Schlenk equilibrium is a complex reaction governing the presence of multiple chemical species in solution of Grignard reagents. The full characterization at the molecular level of the transformation of CH3MgCl into ...

Molecular dynamics simulations (dissipative particle dynamics–DPD) were developed and used to quantify wall-normal migration of polymer chains in microchannel Poseuille flow. Crossflow migration due to viscous interaction ...

A one pot catalytic system which involves Cu and an alkoxide co-catalyst has been used for methanol (MeOH) synthesis at low temperature. Up to about 92% syngas conversion per pass and more than 90% selectivity to MeOH (the ...

We present the first analytic implementation of cubic and quartic force constants at the level of Kohn–Sham density-functional theory. The implementation is based on an open-ended formalism for the evaluation of energy ...

Two forms, α and β, are known for the racemic amino acid DL-me­thio­nine, C5H11NO2S. The phase transition between them, taking place around 326 K, is associated with sliding at the central inter­faces of the hydro­phobic ...
