Further use of this new spectroscopy technique was shown for the characterisation of different forms of carbon, such as nanotubes and nanofibres. The relationship between the University of Cambridge and Johnson Matthey has shown how academics and industrialists can work together to develop techniques that are useful in solving real technical problems.However,it was pointed out that a beneficial return is rarely achieved quickly, and it was thought that such collaborations need to be long-term (of at least five years’ duration) to be truly effective. Short Talks and Poster Prizes There were also a number of short talks and a poster session in which doctoral students presented their latest research.A prize was awarded for the best overall talk given by a student and this went to Sarah Burton (née Hudson) (University of Southampton, UK; now working at Johnson Matthey Fuel Cells, Swindon, UK) for her talk entitled ‘A Comparative Study of Alloys and Platinum for Fuel Cell Applications’.Burton described the challenges facing the commercialisation of fuel cell vehicles and the ways in which alloying with cobalt has resulted in increases in activity (9) and improved stability (10) for fuel cell cathode catalysts.She also showed how a greater understanding of these phenomena could be obtained using X-ray absorption spectroscopy (XAS) (11). Using this technique, the study of structural changes in the catalyst can now be observed during fuel cell operation. Prizes for the best posters were also awarded, with Paul Rounce (University of Birmingham,UK) winning the second year prize with his poster ‘Speciation of Particulate Matter (PM) from Compression Ignition Engines for a Range of Fuels and Biofuels’,and Haibo E (University of Oxford, UK) taking the first year prize with her poster entitled ‘Custom Microscopy Techniques for Imaging of Core-Shell Catalyst Particles’. Concluding Remarks The JMAC 09 conference was deemed a huge success with a high standard of technical presentations and posters that stimulated much debate. Such events have proved mutually beneficial for both academics and industrialists in approaching and tackling key global challenges. z, mm 40 30 20 10 Liquid axial velocity, mm s –1 248 165 83 0 Fig. 4.
