X-Ray absorption spectroscopy on airborne aerosols
It is demonstrated that X-ray absorption spectroscopy can be used to analyze the chemical state of airborne aerosols in situ under controlled conditions.

Using coherent X-rays to follow dynamics in amorphous ices
Amorphous ice plays an important role in our overall understanding of water's phase diagram.
Paper
Night-time oxidation at the air–water interface: co-surfactant effects in binary mixtures
The ageing of organic-coated aqueous aerosols at night is investigated by reacting NO3 with binary surfactant mixtures floating on water.
Paper
Orcinol and resorcinol induce local ordering of water molecules near the liquid–vapor interface
Resorcinol and orcinol are surface active in aqueous solution, self-aggregate into islands and induce tetrahedral ordering in nearby water. This may be relevant for ice nucleation promoted by phenolic species in the atmosphere.
Paper
Surface composition of size-selected sea salt particles under the influence of organic acids studied in situ using synchrotron radiation X-ray photoelectron spectroscopy
Synchrotron X-ray photoelectron spectroscopic surface characterisation of size-resolved sea salt aerosol particles revealed Mg enrichment in the particle surface layer which was either enhanced or decreased depending on the organic compound added.
Paper
The evolution of surface structure during simulated atmospheric ageing of nano-scale coatings of an organic surfactant aerosol proxy
A nano-scale proxy for atmospheric surfactant organic films undergoes changes in morphology and hygroscopicity during simulated atmospheric processing.
Paper
Changes to lung surfactant monolayers upon exposure to gas phase ozone observed using X-ray and neutron reflectivity
Lung surfactant at the air water interface reacts with ozone leading to changes in surface tension, film thickness, structure.
Paper
Chemical composition and morphological analysis of atmospheric particles from an intensive bonfire burning festival
Atmospheric particles were sampled in Rehovot, Israel during a national Lag Ba'Omer bonfire festival as a case study to investigate the physical and chemical transformations of mixed mineral dust and biomass burning (BB) aerosols.
Paper
Measurement of gas-phase OH radical oxidation and film thickness of organic films at the air–water interface using material extracted from urban, remote and wood smoke aerosol
The presence of an organic film on a cloud droplet or aqueous aerosol particle has the potential to alter the chemical, optical and physical properties of the droplet or particle.
Paper
Ice nucleation imaged with X-ray spectro-microscopy
Ice nucleation can now be imaged in situ using X-ray spectro-microscopy in a new experiment, which is applied to mineral aerosol particles composed of ferrihydrite or feldspar and associated organic matter.
Paper
Surface solvation of Martian salt analogues at low relative humidities
Salt aerosols play important roles in many processes related to atmospheric chemistry and the climate systems on both Earth and Mars.
