Heterogeneous nucleation of nitric acid trihydrate on clay minerals: relevance to Type Ia polar stratospheric clouds
Article Abstract:
A high-vacuum chamber equipped with transmission Fourier transform infrared spectroscopy and a quadrupole mass spectrometer is used for studying heterogeneous nucleation of nitric acid trihydrate (NAT) on two clay minerals as analogs of atmospheric terrestrial and extraterrestrial minerals. The results have shown that NAT nucleation on mineral particles might not be an important nucleation platform for Type Ia polar stratospheric clouds (PSCs) under normal polar stratospheric conditions

Ab initio aqueous thermochemistry: application to the oxidation of hydroxylamine in nitric acid solution
Article Abstract:
A technique for the estimation of the enthalpy of formation and entropy in aqueous solution is presented. Findings reveal that the mean absolute deviations (MADs) for solution-phase enthalpy of formation estimates were 1.5-3 kcal/mol.
