Laboratory studies of heterogeneous reactions important for ozone depletion over Antarctica
are reported. The reaction of chlorine nitrate (ClONO 2 ) with H 2 O and hydrogen chloride (…

Recent exploration by the Cassini/Huygens mission has stimulated a great deal of interest in
Saturn's moon, Titan. One of Titan's most captivating features is the thick organic haze layer …

Prion diseases are unusual because they can arise spontaneously in the population at large
without any apparent cause-socalled sporadic forms--or they can be familial and tightly …

Reactions of methylglyoxal with amino acids, methylamine, and ammonium sulfate can take
place in aqueous aerosol and evaporating cloud droplets. These processes are simulated …

Immersion freezing is the most relevant heterogeneous ice nucleation mechanism through
which ice crystals are formed in mixed-phase clouds. In recent years, an increasing number …

Glyoxal, the simplest and most abundant α-dicarbonyl compound in the atmosphere, is
scavenged by clouds and aerosol, where it reacts with nucleophiles to form low-volatility products…

The reactions of dinitrogen pentoxide (N 2 O 5 ) with H 2 O and hydrochloric acid (HCl) were
studied on ice surfaces in a Knudsen cell flow reactor. The N 2 O 5 reacted on ice at 185 K …

The deliquescence and efflorescence phase transitions of ammonium sulfate aerosols have
been studied as a function of relative humidity (RH) over the temperature range from 234 K …

Glyoxal reacts with methylamine in drying cloud droplet/aerosol surrogates to form high
molecular mass oligomers along with smaller amounts of 1,3‐dimethylimidazole and light‐…

Glyoxal and methylglyoxal are scavenged by clouds, where a fraction of these compounds
are oxidized during the lifetime of the droplet. As a cloud droplet evaporates, the remaining …
