By admin, on November 20th, 2015% 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.

By admin, on September 5th, 2012% It has been announced today that our group member Sin-Yuen Chang is one of the three finalists for the 2012 Science, Engineering and Technology (SET) Student of the Year Awards in Chemical Engineering. The SET Awards are Europe’s most important awards for science and technology undergraduates. There were nearly five hundred entries for the Chemical Engineering award this year, so it is already a considerable achievement to have been shortlisted.
The full list of all 2012 SET award finalists is available here.

By admin, on July 13th, 2012% Two MEng graduates who have pursued their final year dissertation research with us this academic year have been awarded PhD studentships to re-join us in September.
James Black, who has just completed his MEng dissertation on laser-ablation ICP-MS analysis of prehistoric pottery, will work in a project funded by GSK and EPSRC, investigating the effect of impurities on polymorphic forms. His main supervisor will be Roger Davey and he will be co-supervised by Sven Schroeder.
Sin-Yuen Chang will return on a President’s Doctoral Scholar award to investigate low-energy alternative technologies for wastewater treatment by in situ generation of hydrogen peroxide with novel catalysts. This project is a continuation of Sin-Yuen’s MEng dissertation project. Sven Schroeder will be her main supervisor and Ted Roberts her co-supervisor.
Congratulations to both! We are all looking foward to seeing James and Sin-Yuen again in September.
