Negative thermal expansion and oxygen disorder in cubic ZrMo2O8 (2003)
Journal Article
Allen, S., & Evans, J. (2003). Negative thermal expansion and oxygen disorder in cubic ZrMo2O8. Physical Review B, 68(13),

In this paper we report precise thermal expansion data for the cubic negative thermal expansion material gamma-ZrMo2O8 which has an average expansion coefficient of -6.9x10(-6) K-1 between 2 and 200 K and -5.0x10(-6) K-1 between 250 and 502 K. Therma... Read More about Negative thermal expansion and oxygen disorder in cubic ZrMo2O8.

alpha-Bi2Sn2O7 - a 176 atom crystal structure from powder diffraction data (2003)
Journal Article
Evans, I., Howard, J., & Evans, J. (2003). alpha-Bi2Sn2O7 - a 176 atom crystal structure from powder diffraction data. Journal of materials chemistry, 13(9), 2098-2103. https://doi.org/10.1039/b305211g

Pyrochlore-type bismuth tin oxide, Bi2Sn2O7, is a technologically important material used in applications such as catalysis and gas sensing. Its room temperature structure has been solved by a method of simulated annealing of combined X-ray and neutr...

Characterization of the room-temperature structure of SnP2O7 by P-31 through-space and through-bond NMR correlation spectroscopy (2003)
Journal Article
Fayon, F., King, I., Harris, R., Gover, R., Evans, J., & Massiot, D. (2003). Characterization of the room-temperature structure of SnP2O7 by P-31 through-space and through-bond NMR correlation spectroscopy. Chemistry of Materials, 15(11), 2234-2239

The room-temperature structure of SnP2O7 has been investigated using various one- and two-dimensional (1- and 2D) magic-angle spinning (MAS) NMR experiments. We show that P-31 homonuclear through-bond and through-space correlation NMR spectroscopies...

Structural investigations of three triazines: solution-state NMR studies of internal rotation and structural information from solid-state NMR, plus a full structure determination from powder x-ray diffraction in one case (2003)
Journal Article
Birkett, H., Cherryman, J., Chippendale, A., Evans, J., Harris, R., James, M., …McPherson, G. (2003). Structural investigations of three triazines: solution-state NMR studies of internal rotation and structural information from solid-state NMR, plus a full structure determination from powder x-ray diffraction in one case. Magnetic Resonance in Chemistry, 41(5), 324-336

Three model 2,4,6-tris(amino)-1,3, 5-triazines, structurally related to a dyestuff molecule previously studied by NMR, were synthesized in order to enable the effects of rotamer exchange on the NMR spectra to be investigated in more detail. Two of th...

An X-ray diffraction and MAS NMR study of the thermal expansion properties of calcined siliceous ferrierite (2003)
Journal Article
Bull, I., Lightfoot, P., Villaescusa, L., Bull, L., Gover, R., Evans, J., & Morris, R. (2003). An X-ray diffraction and MAS NMR study of the thermal expansion properties of calcined siliceous ferrierite. Journal of the American Chemical Society, 125(14), 4342-4349

Powder and single-crystal X-ray diffraction, combined with MAS NMR measurements, has been used to study the thermal expansion of siliceous zeolite ferrierite as it approaches a second-order displacive phase transition from a low-symmetry (Pnnm) to a...
