Committee Members' Biographies
Dr Maurice Webb CChem FRSC
Following a BSc in Chemistry at Manchester, a DPhil in metallocene chemistry at Sussex then a short spell teaching Physics, Maurice Webb's career has involved R&D and new business creation roles in a number of companies (CIBA-Geigy, Laporte, Unilever, ICI, Ineos); with Government Knowledge Transfer schemes and currently as an independent consultant. His primary interest is the industrial applications of materials chemistry, especially inorganics (eg silicas, zeolites, silicates, mixed metal hydroxides), in the consumer goods and chemicals-using industries (incl. healthcare, water and waste treatment, polymers, catalysts, toiletries and detergent and household products).
Professor Craig Williams CChem FRSC
Prof. Craig Williams is Professor of Meso & Microporous Materials at the University of Wolverhampton, he has over 20 years experience within the zeolite community, establishing the meso and microporous research group at Wolverhampton in 1993 to study the problems involved in zeolite synthesis and isomorphous substitution. In 1999 he was elected a Fellow of the Royal Society of Chemistry (RSC) and has served the RSC as Secretary and Chair of the Analytical Division of the Midlands Region and Secretary of the Applied Materials Chemistry Group. He is also Secretary of the British Zeolite Association (BZA), for the second time. His research background is a balance of synthesis, diffusion and catalytic applications.
In 1994 his group discovered a method of loading zeolites with metals replacing up to 82.5% of the total aluminium content. This method involved the use of tetrahedral oxo anion metal species MO4n-. Initially work was centred on zeolite L and the substitution of iron and manganese into the zeolite framework. The work proved to be so successful that the methodology for iron and manganese substitution into a variety of zeolites was patented as well as being published. The iron containing zeolite L has been catalytically tested. This study showed that the product distribution for the framework iron species was very different from that achieved using iron ion-exchanged into the zeolite.
The research group at Wolverhampton also studies isomorphous substitution into aluminophosphate molecular sieves and again this work has been widely published. The group have also looked at minimising reagent waste during zeolite synthesis, examining zeolites as soil benefactors for the growth cereal crops and studied zeolite based auto catalysts.
Dr Philip Mitchell MRSC
Philip Mitchell was formerly Reader in Chemistry and Leverhulme Emeritus Fellow, University of Reading.
M.A., D.Phil. University of Oxford.
His specialities include inorganic chemistry especially molybdenum chemistry; catalysis and surface science; application of neutron scattering methods.
Dr Alan Armour CChem MRSC
Immediate Past Chairman
Alan studied chemistry at the University of Reading completing his PhD in 1972 on studies of molybdenum containing catalysts. Following a period with the UK Atomic Energy Authority he joined Climax Molybdenum with whom he has held a number of sales, marketing and technical development positions.
He is currently Director of Global Chemical Sales & Development and is the current Chairman of the Industrial Inorganic Chemicals Sector.
Dr Andrew Dunster CChem MRSC
Dr Andrew Dunster is the Principal Consultant at BRE (Building Research Establishment). Andrew manages projects on low carbon cements and the use of industrial by-products as construction aggregates, within BRE’s Building Technology Group. He also provides research and consultancy on construction products with recycled content (including rubber, plastics, glass). His other main areas of expertise are in the assessment and utilisation of slags from metals processing, performance of calcium aluminate cements, cement chemistry and the durability of concrete in aggressive environments.
He is currently working on several major market-focussed projects on low carbon cements, waste derived organic fibres and resource efficient and sustainable construction. Andrew has also published widely and his publications since the late 1980’s include many technical guidance documents and journal papers. He is also a member of the Sustainability Group of the Institute of Minerals, Mining and Metallurgy.
