Our group member Sin-Yuen Chang has passed her PhD viva subject to very minor corrections, and has already submitted the revised thesis, titled “Studies of Metal Speciation and Nucleation in Complex Functional Liquid Systems“. Sin-Yuen has already taken up a position at Diamond Light Source, and a visiting appointment at the University of Leeds, through which she will continue to collaborate with our team. Congratulations , Dr Chang!
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 formed as intermediates, and identifies the nature of the (also time dependent) thiolate side products.

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:
