Tony West obtained his BSc degree in Chemistry at University College Swansea and his PhD at the University of Aberdeen, where he worked with Professor F. P. Glasser on silicate chemistry. He was appointed as a Lecturer in Aberdeen in 1971 and developed a lifetime interest in the then-emerging field of solid state chemistry with special interest in the synthesis of new oxide materials, their crystal structures and electrical properties. He was awarded a DSc from Aberdeen in 1984 and rose through the ranks to become Professor of Chemistry in 1989 before moving to the University of Sheffield, Department of Materials Science and Engineering, as Head of Department in 1999, a post he held until 2007.

Tony was founding editor of the Journal of Materials Chemistry and subsequently established the Materials Chemistry Forum,which has now become the Materials Chemistry Division of the Royal Society of Chemistry. He organised the First International Conference on Materials Chemistry, MCI, in Aberdeen, 1993, and co-organised the first Materials Discussion, MDI, in Bordeaux, 1998. He also served as President of the Inorganic Chemistry Division of IUPAC, 2004–2007.

Tony is a Fellow of the Royal Society of Chemistry, the Institute of Physics, the Institute of Materials, Minerals and Mining, and the Royal Society of Edinburgh. Over the years he has received several awards, including an Industrial Award in Solid State Chemistry from the RSC (1996), the Griffiths Medal and Prize from the IOM3 (2008), the Epsilon de Oro Award from the Spanish Society of Glass and Ceramics (2007) and the Chemical Record Lectureship from the Chemical Societies of Japan (2009). He has been awarded the 2013 John B. Goodenough Award in Materials Chemistry by the RSC, a lifetime award which recognises exceptional and sustained contributions to the field of materials chemistry.

He has >450 research publications (listed below) and best-selling books on solid state chemistry. He is currently preparing a second edition of 'Solid State Chemistry and its Applications' and a student edition is scheduled for publication in January 2014.

Research interests

His research is a blend of the Chemistry, Physics and Engineering of Inorganic Materials, especially oxides, which focuses on materials with interesting and/or useful electrical properties, especially ionic conductors, mixed ionic/electronic conductors, semiconductors, ferro- and di-electrics. His research programmes are broadly-based and cover a wide variety of experimental techniques, including:

  • Synthesis and crystal structure determination of new oxide materials.
  • Use of phase diagrams to determine mechanisms of doping and solid solution formation and to study polymorphism of inorganic and organic (amino acid-based) materials.
  • Electrical property measurements, especially using impedance spectroscopy. to characterise ceramics and measure their conductivity and permittivity.
  • Electrochemical testing of materials for possible use as anodes or cathodes in lithium ion batteries.

Key projects

  • development of new materials for lithium battery applications, including spinels such as LiCoMnO4, which exhibit a 5V redox couple Co3+/4+ on lithium (de) intercalation
  • synthesis and characterisation of new rare earth ion-doped barium titanate, BaTiO3, which has a room temperature permittivity of ~20,000 when doped with La (In collaboration with Dr Derek Sinclair)
  • synthesis and characterisation of new solid electrolytes (mainly Li+ and 0= ion conductors)
  • understanding the structure-property correlations that control the performance of zinc oxide varistors and barium titanate positive temperature coefficient of resistance devices
  • Synthesis of novel oxides with tetragonal tungsten bronze structure with relaxor ferroelectric character for possible capacitor and microwave dielectric applications
  • Synthesis of high purity electroceramics by sol-gel methods (in collaboration with Univ. Jaume I, Spain)
  • Development of novel memristive phenomena for memory and switching applications.
