Publikováno v: Journal of Macromolecular Science, Part B. 35:199-213

A new application of energy dispersive x-ray diffraction to the kinetics of phase transitions is reported. The aim of this work is to provide a new investigation tool to follow the evolution of polymeric systems from the initial to the final phase. T

X-ray and neutron diffraction studies of the hydration of SeO2-4and CrO2-4anions by isomorphic substitution

Autor: R. Felici, F. Cilloco, R. Caminiti

Publikováno v: Molecular Physics. 76:681-691

The structure in aqueous solutions of the hydrated selenate and chromated ions SeO2- 4 and CrO2- 4 have been derived from X-ray and neutron diffraction measurements using CrO2- 4 as an isomorphous substitute for SeO2- 4. The Se(Cr)-O bond lengths are

Neutron-diffraction measurements on liquid benzene

Autor: R. Felici, F. Cilloco, P. Bosi

Publikováno v: Molecular Physics. 70:455-463

We report on neutron-diffraction measurements of liquid benzene under standard thermodynamic conditions. The measurements are taken at two different incident neutron wavelengths to cover an extended Q range. The diffraction data are normalized and in

The TOSCA incoherent inelastic neutron spectrometer: progress and results

Autor: F.P. Ricci, Milva Celli, Stewart F. Parker, F. Cilloco, Daniele Colognesi, Francesco Sacchetti, V. Rossi-Albertini, Marco Zoppi, Z.A. Bowden, Robert J. Newport, John Tomkinson

The back-scattering part (phase I) of the new incoherent inelastic neutron spectrometer, TOSCA, replacing the old TFXA, has been successfully installed at the ISIS pulsed neutron spallation source. The results, owing to the much larger detector area,

Temperature dependence of PEO phase transition rate by energy dispersive X-ray diffraction

Autor: Fausto Croce, F. Cilloco, Claudia Sadun, V. Rossi Albertini, Ruggero Caminiti

Publikováno v: Scopus-Elsevier

A new energy dispersive x-ray diffraction method was used to observe isothermal phase transitions of a polyethylene oxide sample contained in a variable temperature cell. A series of scattering measurements were performed to follow the time evolution

A data acquisition system designed to acquire time of flight spectra in neutron scattering experiments is described. The system is completely hardware, so that even employing a relatively slow clock (1 MHz) it is adequate to work at 300 kHz with no l

The intermolecular potential of methane A neutron diffraction study on low-density CD4

Autor: F. Cilloco, E. Guarini, Fabrizio Barocchi, Renato Magli, Ubaldo Bafile

Publikováno v: Physica B: Condensed Matter. :353-354

Neutron diffraction on low-density systems offers the possibility of a direct probing of the intermolecular forces. This method, used in the last few years for monatomic systems like rare gases, is applied here to the case of gaseous CD 4 at low dens
