  • Characterising density fluctuations in liquid yttria aluminates with small angle x-ray scattering 
    Greaves, G. N.; Wilding, M. C.; Van, Quang Vu; Majerus, Odile; Hennet, Louise (American Institute of Physics, 2009-01-29)
    Small angle x‐ray scattering (SAXS) has been measured in the wavevector range 0.01<Q<1 math−1 for supercooled yttria‐alumina melts using a laser‐heated aerodynamic furnace. SAXS intensity rises gradually with temperature ...
  • Inelastic X-ray Scattering Studies of Zeolite Amorphisation 
    Greaves, G. N.; Kargl, F.; Ward, D.; Holliman, P.; Meneau, F. (American Institute of Physics, 2009-01-29)
    In situ inelastic x-ray scattering (IXS) experiments have been used to probe heterogeneity and deformability in zeolte Y as this thermally collapses to a high density amorphous (HDA) aluminosilicate phase. The Landau-Placzek ...
  • Liquid-liquid transitions, crystallization and long range fluctuations in supercooled yttrium oxide-aluminium oxide melts 
    Greaves, G. N.; Wilding, M. C.; Fearn, S.; Kargl, F.; Hennet, L.; Bras, W.; Majerus, O.; Martin, Chris M. (2009-05-01)
    Employing small angle X-ray scattering (SAXS) and wide angle X-ray scattering (WAXS) combined with laser-heated aerodynamic levitation has enabled different transitions in Supercooled yttrium oxide-aluminium oxide to be ...
  • Melting and Amorphisation 
    Greaves, G. N. (Royal Society of Chemistry, 2007-11-01)
  • Nanocrystal Growth in Cordierite Glass Ceramics Studied with X-ray Scattering 
    Bras, W.; Clark, S. M.; Greaves, G. N.; Kunz, M.; Beek, W. van; Radmilovic, V. (2009-03-01)
    The development of monodisperse crystalline particles in cordierite glass doped with Cr3+ after a two-step heat treatment is elucidated by a combination of time-resolved small and wide angle x-ray scattering (SAXS/WAXS) ...
  • Poisson’s ratio and modern materials 
    Greaves, G. N.; Greer, A. L.; Lakes, R. S.; Rouxel, T. (2011-11-30)
    In comparing a material's resistance to distort under mechanical load rather than to alter in volume, Poisson's ratio offers the fundamental metric by which to compare the performance of any material when strained elastically. ...
  • Polyamorphism and the universal liquid–liquid 
    Greaves, G. N. (ScolarOne, 2011-01-21)
    The physics of critical phenomena is well established in systems as diverse as molecular fluids, crystalline alloys and magnetic materials. As the critical point is approached, the susceptibility increases anomalously and ...
  • Two million hours of science 
    Greaves, G. N.; Catlow, C. R. A.; Derbyshire, G. E.; McMahon, M. I.; Nelmes, R. J.; Van der Lann, G. (2008-11-01)
    After over a quarter of a century, the doors of the world's first synchrotron radiation source have closed. Its contribution to materials science in the past and the future should not be underestimated.
