Different photolysis kinetics at the surface of frozen freshwater vs. frozen salt solutions
Different photolysis kinetics frozen freshwater frozen salt solutions
2010/11/30
Reactions at air-ice interfaces can proceed at very different rates than those in aqueous solution, due to the unique disordered region at the ice surface known as the quasi-liquid layer (QLL) . The p...
Heterogeneous chemistry of monocarboxylic acids on α-Al2O3 at different relative humidities

2010/8/25
A study of the atmospheric heterogeneous reactions of formic acid, acetic acid, and propionic acid on α-Al2O3 was performed at ambient condition by using a diffuse reflectance infrared Fourier transfo...
CCN predictions using simplified assumptions of organic aerosol composition and mixing state: a synthesis from six different locations
CCN predictions organic aerosol composition a synthesis six different locations
2010/8/13
An accurate but simple quantification of the fraction of aerosol particles that can act as cloud condensation nuclei (CCN) is needed for implementation in large-scale models. Data on aerosol size dist...
