Two binary biodegradable Mg-alloys and one ternary biodegradable Mg-alloy (Mg-0.3Ca, Mg-5Zn and Mg-5Zn-0.3Ca, all in wt%) were investigated.
View Article and Find Full Text PDFA major fraction of atmospheric aerosol particles, which affect both air quality and climate, form from gaseous precursors in the atmosphere. Highly oxygenated organic molecules (HOMs), formed by oxidation of biogenic volatile organic compounds, are known to participate in particle formation and growth. However, it is not well understood how they interact with atmospheric pollutants, such as nitrogen oxides (NO ) and sulfur oxides (SO ) from fossil fuel combustion, as well as ammonia (NH) from livestock and fertilizers.

- Nucleation and growth of aerosol particles from atmospheric vapors are important for forming cloud condensation nuclei (CCN), particularly for particles smaller than 10 nm that face significant losses from coagulation.
- Recent findings indicate that oxidation products from biogenic volatile organic compounds are key to particle formation and initial growth; however, the role of these oxidized organics in particle growth across various temperatures remains uncertain.
- Experiments conducted in the CLOUD chamber at CERN reveal that organic particle growth occurs across a broad temperature range, with growth rates influenced by particle curvature and supported by a gas-phase model of oxidized organic molecules.
