Light absorbing carbon (LAC), also referred to as black carbon (BC) or more colloquially as soot; is generated from the partial combustion of fossil fuels and biomass. The significant research interest in BC is largely due to its aerodynamic diameter

We present a new analysis tool and user interface for batch analysis of PIXE, PIGE, RBS and PESA spectra of thin samples. IBA analysis techniques are ideally suited for aerosol filter analysis, because of their high sensitivity and because the layer

Sampling of PM2.5 has been undertaken twice per week at the Liverpool and Mascot sites (in Sydney, Australia) since 1998. Ion Beam Analysis (IBA) was applied to each sample to determine the concentrations of 21 elements from hydrogen to lead and the

Fine particle air pollution is a significant problem in large urbanised areas across the Asian region. With funding from the International Atomic Energy Agency (IAEA) fifteen countries in Asia have been collecting weekly samples on filters of fine an

We present the results concerning the development in Geant4 of a new data driven library, called here the ANSTO HF library. This X-ray fluorescence library is based on an approach of particular interest for PIXE simulation applications; however, it c

The outputs of the multi-elemental IBA techniques of PIXE, PIGE, RBS and PESA have been used as inputs to positive matrix factorisation source apportionment methods to quantify and fingerprint bushfire smoke during the catastrophic black summer bushf

Heavy ion Particle Induced X-ray Emission (PIXE) spectroscopy offers a number of advantages over standard proton PIXE, such as higher yields and therefore higher sensitivity. However, in order to be able to use heavy ion PIXE more detailed measuremen

Sea salt is one of the major aerosols in the atmosphere in both the fine and coarse size ranges. Newly formed sea salt particles have a similar composition to seawater; including elements such as Na, Cl, Mg, S, Ca, Br and K. However, once in the atmo

Molybdenum (Mo) is a key cofactor in enzymes used for nitrogen (N) fixation and nitrate reduction, and the low availability of Mo can constrain N inputs, affecting ecosystem productivity. Natural atmospheric Mo aerosolization and deposition from sour
