Sustainable Heavy Metal Removal from Mining Effluents

We have just published a study of sustainable heavy metal removal from copper mining effluents in Chile by use of bark chips, a sustainable by-product of the local forestry industry.

Sweet X-ray spectroscopy

We recently realised that Near-edge X-ray absorption fine-structure (NEXAFS) spectroscopy at the C K-edge can distinguish between different saccharides because minute variations in average C-O bond lengths manifest as detectable shifts of the shape resonances associated with these bonds. This opens up the possibility for novel analytical approaches, for example to identify different types of sugars in drug formulations or foods:

Paper comparing peptide surface functionalisation methods for poly-caprolactone

We have published an XPS study comparing two methods for poly-caprolactone surface functionalisation with cell-binding RGD peptides.

Paper on XPS of Amino Acids and Peptides

Having made some unexpected impact with our 2009 Surface and Interface Analysis paper on the XPS of saccharides (see here), we are now publishing a conceptually similar paper, this time dealing with the XPS of several amino acids and peptides derived from them:
