| Zusammenfassung |
| Cloud condensation nuclei act as cores for water vapour condensation, and
their composition and chemical properties may enhance or depress the ability
for droplet growth. In this study we use molecular dynamics simulations to
show that model humic-like substances (HULIS) in systems containing
10 000 water molecules mimic experimental data well referring to reduction of
surface tension. The model HULIS compounds investigated in this study are
cis-pinonic acid (CPA), pinic acid (PAD) and pinonaldehyde (PAL). The
structural properties examined show the ability for the model HULIS
compounds to aggregate inside the nanoaerosol clusters. |
