CHANGES IN THE LOCAL COORDINATION OF TRACE RARE-EARTH ELEMENTS IN GARNETS BY HIGH-ENERGY XAFS: NEW DATA ON DYSPROSIUM

Quartieri S.; Dalconi M.C.; Boscherini F.; Oberti R.; D'Acapito F. (2004)

The site location and local geometry of trace amounts (299 ppm) of dysprosium in a natural melanite garnet from a carbonatitic rock have been studied by high-energy fluorescence-detected X-ray absorption fine-structure ...
CHARACTERIZATION OF TRACE ND AND CE SITE PREFERENCE AND COORDINATION IN NATURAL MELANITES: A COMBINED X-RAY DIFFRACTION AND HIGH-ENERGY XAFS STUDY

Quartieri S.; Boscherini F.; Chaboy J.; Dalconi M.C.; Oberti R.; Zanetti A. (2002)

Natural melanite garnets from carbonatitic rocks have been studied by a multitechnique approach based on both experimental (chemical, diffractometric and spectroscopic) methods and full-multiple scattering calculations of ...
DEHYDRATION DYNAMICS OF BIKITAITE: PART I. IN SITU SYNCHROTRON POWDER X-RAY DIFFRACTION STUDY

Ferro O.; Vezzalini G.; Quartieri S.; Ceriani C.; Fois E.; Gamba A.; Cruciani G. (2004)

The thermal dehydration process of the natural Li zeolite bikitaite has been studied in situ by synchrotron radiation powder diffraction. The temperature-resolved experiments were performed using a translating imaging plate ...
FE2+-O AND MN2+-O BONDING AND FE2+- AND MN2+-VIBRATIONAL PROPERTIES IN SYNTHETIC ALMANDINE-SPESSARTINE SOLID SOLUTIONS: AN X-RAY ABSORPTION FINE STRUCTURE STUDY

Sani A.; Quartieri S.; Boscherini F.; Antonioli G.; Feenstra A.; Geiger C.A. (2004)

X-ray absorption fine structure (XAFS) measurements at the Fe and Mn K-edges were undertaken to investigate the Fe2+-O and Mn2+-O bonding, and Fe2+- and Mn2+-vibrational properties for a series of synthetic almandine-spessartine, ...
HIGH-PRESSURE BEHAVIOR OF BIKITAITE: AN INTEGRATED THEORETICAL AND EXPERIMENTAL APPROACH

Ferro O.; Quartieri S.; Vezzalini G.; Fois E.; Gamba A.; Tabacchi G. (2002)

Pressure-induced structural modifications in the zeolite bikitaite are studied by means of in situ synchrotron X-ray powder diffraction and ab initio molecular dynamics. The experimental cell parameters were refined up to ...
HIGH-PRESSURE DEFORMATION MECHANISM IN SCOLECITE: A COMBINED COMPUTATIONAL-EXPERIMENTAL STUDY

Ballone P.; Quartieri S.; Sani A.; Vezzalini G. (2002)

Pressure-induced structural modifications in scolecite were studied by means of in situ synchrotron X-ray powder diffraction and density functional computations. The experimental cell parameters were refined up to 8.5 GPa. ...
STRUCTURAL DEFORMATION MECHANISMS OF ZEOLITES UNDER PRESSURE

Arletti R.; Ferro O.; Vezzalini G.; Quartieri S.; Sani A.; Tabacchi G. (2003)

The HP behavior of the natural zeolite yugawaralite and of the synthetic zeolite Na-A was studied by in situ synchrotron X-ray powder diffraction, using a non-penetrating P-transmitting medium. The unit-cell parameters of ...
