Castelijns, H.J. (author), Huinink, H.P. (author), Pel, L. (author), Zitha, P.L.J. (author)The coupled mass transfer and chemical reactions of a gel-forming compound in a two-phase system were studied in detail. Tetra-methyl-ortho-silicate (TMOS) is often used as a precursor in sol-gel chemistry to produce silica gels in aqueous systems. TMOS can also be mixed with many hydrocarbons without chemical reaction, which allows for various...journal article 2006

Kearley, G.J. (author), Johnson, M.R. (author), Tomkinson, J. (author)The lattice dynamics and molecular vibrations of benzene and deuterated benzene crystals are calculated from force constants derived from density-functional theory (DFT) calculations and compared with measured inelastic neutron-scattering spectra. A very small change (0.5%) in lattice parameter is required to obtain real lattice-mode frequencies...journal article 2006

Burns, G.R. (author), Favier, F. (author), Jones, D.J. (author), Rozière, J. (author), Kearley, G.J. (author)Tetrathiafulvalene (TTF) is a key molecule in the family of charge-transfer salts of interest for their novel transport properties. The correspondence between transport property and electron-molecular vibration coupling requires that we understand the phonon density of states for these materials. Here we report the results of a low temperature...journal article 2003
