Four component catalysis for the hydroalkylation of benzene to cyclohexyl benzene

Autor: J Fahy, D.J Cookson, David L. Trimm

Publikováno v: Applied Catalysis A: General. 211:259-268

Patent claims that benzene can be hydroalkylated to form cyclohexyl benzene — a potential diesel fuel — over a four component catalyst have been verified, and the role of the individual components has been explored. The hydrogenation of benzene o

Publikováno v: Journal of Solid State Chemistry. 139:238-247

At room temperature the sequence of phases with increasing amounts of strontium in the system CaTiO 3 /SrTiO 3 is orthorhombic ( Pnma ), orthorhombic ( Bmmb ), tetragonal ( I 4/ mcm ), and cubic ( Pm 3 m ). All phase boundaries shift toward smaller s

Publikováno v: Acta Crystallographica Section B Structural Science. 53:861-869

The structures of the layered intergrowth phases SbIIISb^{\rm V}_xAl-xTiO6 (x \simeq 0, A = Ta, Nb) have been refined by the Rietveld method, using X-ray diffraction data obtained using a synchrotron source. The starting models for these structures w

Electron microprobe analysis and synchrotron diffraction study of crystalline (Nd0.5Y0.5)Ba2Cu3O7−δ

Autor: J.W. Cochrane, G. Foran, P.A. Miles, G.J. Russell, D.J. Cookson

Publikováno v: Physica C: Superconductivity. 277:213-218

A melt-textured growth process, starting with the composite material (Nd 0.5 Y 0.5 )Ba 2 Cu 3 O 7−δ as feedstock, was used to grow large intergrowth crystals containing 97% (Nd/Y)Ba 2 Cu 3 Of 7−δ [(Nd/Y)123] and 3% (Nd/Y) 2 BaCuO 5 [(Nd/Y)211].

Phonon dispersion relations for potassium thiocyanate at and above room temperature

Autor: Trevor R Finlayson, D.J. Cookson, Margaret M. Elcombe

Publikováno v: Journal of Physics: Condensed Matter. 4:7851-7864

The elastic stiffness constants of KSCN have been measured using a pulse-echo-overlap method at 10 MHz and compared to those for CsSCN. In both crystals it was found that transverse waves propagating normal to the minor planes encountered the greates
