For the best paper on the science and technology of niobium and its alloys, the 2018 Charles Hatchett winners are Dongchang Chen (USA), Jeng-Han Wang (Taiwan), Tsung-Fu Chou (Taiwan), Bote Zhao (USA/China), Mostafa A. El-Sayed (USA) and Meilin Liu (USA), for their paper
Materials for batteries is an area in which there will be significant growth in the near future. Nb2O5 shows extremely attractive performance in terms of charge and discharge rates for Li-ions. The award winning research proposes a mechanism to explain this behaviour, which is supported by experimental Raman spectroscopy measurements and vibrational modelling. In addition, the unique features of the Nb2O5 crystal structure which differentiate it from competing materials provide pointers to how further improvements may be made in the design of the next generation of conduction and storage materials.
The selection process of the Charles Hatchett Award is concerned with technical excellence and originality, but also takes account of the social, economic and environmental advantages of any proposed application of niobium. The International Panel for the Charles Hatchett Award commented, “The research is remarkable because of academic and commercial interest in the smart revolution era. The development of new materials with enhanced performance could give a significant impact on the market.”
The annual Award, now in its 40th year, is sponsored by Companhia Brasileira de Metalurgia e Mineração (CBMM) and administered by Beta Technology. The award winners will be presented with their medals at the Institute of Materials, Minerals and Mining (IOM3) 2018 Premier Awards Dinner, to be held in London on 3rd July.
