Synchrotron radiation excited electron spectroscopy of sea salt aerosol particles

The electronic structure of unsupported nano-objects has long been of fundamental interest, as abrupt changes and surprising quantum phenomena appear when single atom properties evolve to the collective electronic properties of infinite solids. However, also from the applied point of view the investigation of free-standing nano-sized matter is now more timely than ever: nanoparticles are ubiquitous in nature with impact …

Constraining the role of surface-active organics in cloud formation

Aerosol-cloud interactions (ACI) constitute the largest source of uncertainty in global radiative forcing estimates, hampering our understanding of climate sensitivity and evolution. Recent evidence from laboratory and field observations suggest that surface tension depression by organic aerosol may have a significant impact on aerosol-cloud interactions. It remains commonplace however to assume a surface tension of water when predicting cloud droplet …

Coupled cycles of carbon, nitrogen, and phosphorus

It is very likely, based on experimental results and modelling, that nutrient shortage will limi the effect of rising atmospheric CO2 on future land carbon sinks (IPCC AR5). While there is high confidence that nitrogen will limit carbon shortage on land, the role of phosphorus is more uncertain. Daniel S. Coll will present his work which aims at shedding light …
