Congratulations, Dr Chang!

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!

JACS paper!

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.
