The transformation of manufactured nanoparticles under natural conditions is a challenging area of research due to the environmental low concentrations that can be expected at present time. We have investigated the transformation of nanoparticles from consumer products and along the wastewater, biosolid soil pathway using a range of approaches. For instance, we developed and tested a nano in...

Saturn’s largest moon Titan has a chemically diverse atmosphere, an icy surface and is the only other planetary-body with comparable molecular complexity to Earth. Thus, analysis of Titan’s atmosphere can give new insight towards prebiotic Earth chemistry.
In Titan’s atmosphere, ongoing photolytic and radiolytic interactions with N2 and CH4 precursor molecules yield a suite of nitrile...

Greigite (Fe3S4) is a ferrimagnetic iron sulfide mineral, containing both Fe(II) and Fe(III) centres. There is ongoing debate over the role of greigite in sedimentary settings, especially acid sulfate soils: its partially oxidised nature has traditionally been seen as indicative of a metastable intermediate in low temperature sulfide mineralization, however others have...

Iron dosing of membrane bioreactors (MBRs) is widely used as a means of meeting effluent phosphorus targets but there is limited understanding of the nature of iron and phosphorus-containing solids that are formed within the bioreactor (an important issue in view of the increasing interest in recovering phosphorus from wastewaters). Of particular challenge is the complexity of the MBR system...
