Objective: Exposure to airborne particulate matter (PM) is estimated to cause millions of
premature deaths annually. This work conveys known routes of exposure to PM and …

The physical state of a material is described as its phase. Common phases of the molecule
H2O include vapor, liquid water, and ice. Examples of these phases in the atmosphere are …

Sea spray is one of the largest natural aerosol sources and plays an important role in the
Earth's radiative budget. These particles are inherently hygroscopic, that is, they take-up …

Ozone is produced in the troposphere by gas-phase oxidation of hydrocarbons and CO
catalyzed by hydrogen oxide radicals (HOx≡ OH+ H+ peroxy radicals) and nitrogen oxide …

Since its first publication in 1973, the HITRAN molecular spectroscopic database has been
recognized as the international standard for providing the necessary fundamental …

Interactions with water are crucial for the properties, transformation and climate effects of
atmospheric aerosols. Here we present a conceptual framework for the interaction of …

Nanoparticles are discrete nanometer (10-9 m)-scale assemblies of atoms. Thus, they have
dimensions between those characteristic of ions (10-10 m) and those of macroscopic …

The role of water-soluble organic compounds on the hygroscopic properties of atmospheric
aerosols has recently been the subject of many studies. In particular, low molecular weight …

The heterogeneous reaction of N 2 O 5 on mixed organic-inorganic aerosol particles was
investigated using an entrained aerosol flow tube coupled to a custom-built chemical …

Hygroscopicity is one of the most important physicochemical properties of aerosol particles
and also plays indispensable roles in many other scientific and technical fields. A myriad of …
