Unraveling the Uptake of Glyoxal on a Diversity of Natural Dusts and Surrogates: Linking Dust Composition to Glyoxal Uptake and Estimation of Atmospheric Lifetimes
The uptake of glyoxal (Gly) on 28 different samples with varying mineralogical origins, such as clays, mineral proxies, and natural dusts from the major arid regions of the Earth, was determined. Experiments were performed at ambient temperature inside a K ...
Amer Chemical Soc2024Development of Hyphenated Analytical Techniques using spICP-MS for Online Characterization of Metallic Nanoparticles in Aerosols
The presence of metallic nanoparticles (NPs) in aerosols has raised concern about their fate in the environment through natural processes and anthropological activities. The state-of-the-art technologies for direct aerosol characterization cannot reach rea ...
EPFL2024Role of K-feldspar and quartz in global ice nucleation by mineral dust in mixed-phase clouds
Ice-nucleating particles (INPs) enable ice formation, profoundly affecting the microphysical and radiative properties, lifetimes, and precipitation rates of clouds. Mineral dust emitted from arid regions, particularly potassium-containing feldspar (K-felds ...
COPERNICUS GESELLSCHAFT MBH2023Ecological and Climate Impacts of Greenlandic Glacial Outwash Plains (ECO-Plains)
Devis Tuia, Julia Schmale, Nora Bergner, Ianina Altshuler, Gaston Jean Lenczner, Grace Emma Marsh
Glacial outwash plains are developing fast in the Arctic, a region which warms two to four times faster than the global average. These new landscapes are climate relevant. They can be sources and sinks of greenhouse gas fluxes and they expose large amounts ...
