Profile

Martin Stennett joined the Department of Materials Science and Engineering in 2004, as a PDRA, and in 2010 he was appointed to the role of University Teaching Associate in Nuclear Materials Chemistry.

Qualifications

Martin was awarded his PhD from The University of Sheffield in 2004, with a thesis entitled “Structure property relations in tetragonal tungsten bronze-structured dielectric ceramics“. He graduated from The University of Nottingham in 1999 with a BSc (Hons) in Chemistry and Molecular Physics and from The University of Sheffield in 2000 with an MSc in Ceramic Science and Engineering.

Research interests

Structure-property relations in fluorite related metal oxides
Research is focussed on the synthesis and characterisation of oxide-based fluorite and fluorite-related ceramic for applications in nuclear waste immobilisation. Characterisation techniques used include X-ray and electron diffraction, X-ray absorption spectroscopy, and electron microscopy. Properties of interest include chemical durability and tolerance to radiation damage.

Immobilisation of problematic radio-nuclides
Research is focussed on the design, processing and characterisation of tailored ceramic and glass wasteforms for the immobilisation of problematic long-lived radio-nuclides such as 129I, 14C, 99Tc, plutonium and uranium.

Application of novel processing techniques to ceramic and glass synthesis
Research is focussed on the application of techniques such as molten salt mediated synthesis and microwave dielectric heating to the processing of glasses and ceramics for a wide range of applications. Of particular interest is the effect of processing on material properties.

Key projects:

  • Structure-property relations in fluorite and fluorite-related ceramics
  • Synthesis and characterisation of tetragonal tungsten bronze ceramic phases for waste immobilisation
  • Application of novel processing techniques to waste immobilisation
  • Immobilisation of 14C in glass wasteforms fabricated by microwave synthesis
