Under leadership of Akihiro Uehara a combined electrochemical/X-ray absorption spectroscopy study deconstructing the famous Brust-Schiffrin synthesis of gold nanoparticles has been carried out. The results elucidates some of the transformations taking place during this two-phase synthesis. The results show that the reaction at the oil-water interface includes a time dependent evolution of the Au(I) species …
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. Sustainable Natural Adsorbents for Heavy Metal Removal from Wastewater: Lead Sorption on Pine Bark (Pinus Radiata D.Don) G. Montes-Atenas & S. L. M. Schroeder Surface …

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 …
The group has had a good run of publications this year. So far our 2015 output of papers includes: Intermolecular Bonding of Hemin in Solution and in Solid State Probed by N K-edge X-ray Spectroscopies R. Golnak, J. Xiao, K. Atak, J. S. Stevens, A. Gainar, S. L. M. Schroeder & E. F. Aziz Physical …

Two papers from our group have been accepted recently: Conservation of Artists’ Acrylic Emulsion Paints: XPS, NEXAFS and ATR FTIR Studies of Wet Cleaning Methods E.A. Willneff, B.A. Ormsby, J.S. Stevens, C. Jaye, D.A. Fischer, S.L.M. Schroeder Surface and Interface Analysis (2014), early view. DOI:10.1002/sia.5376 Proton Transfer and Hydrogen Bonding in the Organic Solid State: …
A windowless electrochemical cell for the spectroscopic investigation of the liquid-liquid interface, using a dual droplet configuration, has been designed. The setup permits in situ probing of the bulk solutions and the interfacial region by fibre-optic UV-vis spectroscopy, microfocus X-ray fluorescence (XRF) elemental mapping, and microfocus X-ray absorption near-edge structure (micro-XANES) spectroscopy. The electrodeposition of …
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: Quantitative Analysis of Complex Amino Acids and RGD Peptides by X-ray Photoelectron …
