Particles composed of secondary organic material (SOM) are abundant in the lower troposphere. The viscosity of these particles is a fundamental property that is presently poorly quantified yet required for accurate modeling of their formation, growth, evaporation, and environmental impacts.
Secondary organic aerosol formation from volatile precursors can be thought of as a succession of generations of reaction products. Here, we constrain first-generation SOA formation from the α-pinene + OH reaction and also study SOA formation from α-pinene ozonolysis carried

This work investigates the oxidative aging of preformed secondary organic aerosol (SOA) derived from alpha-pinene ozonolysis (-100 ppb(v) hydrocarbon [HC(x)] with excess of O3) within the University of California-Riverside Center for Environmental Research and Technology environmental chamber that occurs after

The kinetics of reactions of α-pinene and β-pinene with hydroxyl radicals (OH) has been investigated at 1-8 Torr and 240-340 K using the relative rate/discharge flow/mass spectrometry (RR/DF/MS) technique. Our kinetic results indicate that at 298 K the rate constant
The estimation of parameter values for mathematical models of biological systems is an optimization problem that is particularly challenging due to the nonlinearities involved. One major difficulty is the existence of multiple minima in which standard optimization methods may fall
