Arsenite sorption and co-precipitation with calcite
Gabriela Roman-Ross, Gabriel Cuello, Xavier Turrillas +2
Sorption of As(III) by calcite was investigated as a function of As(III) concentration, time and pH. The sorption isotherm, i.e. the log As(III) vs. log [As(OH)3 degrees / Assat] p…
Kinetics of crystallization of FeB-based amorphous alloys studied by neutron thermo-diffractometry
Alejandro Fernandez-Martinez, P. Gorria, Gabriel Cuello +2
Kinetics of crystallization of two amorphous alloys, Fe70Cr10B20 and Fe80Zr10B10, have been followed up by neutron thermodiffractometry experiments performed in the two axis diffra…
Structure of chalcogenide glasses by neutron diffraction
Gabriel Cuello, Andrea Piarristeguy, Alejandro Fernandez-Martinez +2
The purpose of this work is to study the change in the structure of the Ge-Se network upon doping with Ag. The total structure factor S(Q) for two samples has been measured by neut…
Arsenic uptake by gypsum and calcite: Modeling and probing by neutron and x-ray scattering
Alejandro Fernandez-Martinez, Gabriel J. Cuello, Gabriela Roman-Ross +4
Here we report on two structural studies performed on As-doped gypsum (CaSO4 2H2O) and calcite (CaCO3), using neutron (D20-ILL) and x-ray (ID11-ESRF) diffraction data and EXAFS (BM…
