The Earth's atmosphere offers a striking contrast with other known planets by its rich organic
composition, which results almost exclusively from the presence of life on the planet. About …

Earth's atmosphere contains a multitude of organic compounds, which differ by orders of
magnitude regarding fundamental properties such as volatility, reactivity, and propensity to …

Secondary organic aerosol (SOA) is ubiquitous in the atmosphere and plays a pivotal role in
climate, air quality, and health. The production of low-volatility dimeric compounds through …

Guaiacyl acetone (GA) is a phenolic carbonyl emitted in significant quantities by wood
combustion that undergoes rapid aqueous-phase oxidation to produce aqueous secondary …

Individual atmospheric particles can contain mixtures of primary organic aerosol (POA),
secondary organic aerosol (SOA), and secondary inorganic aerosol (SIA). To predict the role …

Fine aerosol particles in the urban areas of Shanghai and Los Angeles were collected on
days that were characterized by their stagnant air and high organic aerosol concentrations …

Vanillin (VL), a phenolic aromatic carbonyl abundant in biomass burning emissions, forms
triplet excited states (3 VL∗) under simulated sunlight leading to aqueous secondary …

Organic aerosol particles (OA) play major roles in atmospheric chemistry, climate, and public
health. Aerosol particle viscosity is highly important since it can determine the ability of …

Polar ice cores provide information about past climate and environmental changes over
periods ranging from a few years up to 800,000 years. The majority of chemical studies have …

The molecular composition of humic-like substances (HULIS) in different aerosol samples
was analyzed using an ultrahigh-resolution mass spectrometer to investigate the influence …
