More than a century of non-ferrous metallurgical activities have had a severe impact on the natural environment leading, in most heavily contaminated sites, to a complete loss of the vegetation cover (that is, desert-like areas) or to the selection o

The kinetics of mixed Ni-Al hydroxide formation on clay and aluminum oxide minerals: a time-resolved XAFS study

Autor: André M. Scheidegger, Donald L. Sparks, Daniel G. Strawn, Geraldine M. Lamble

Publikováno v: Geochimica et Cosmochimica Acta. 62:2233-2245

In this study kinetic investigations were combined with X-ray Absorption Fine Structure (XAFS) measurements to determine Ni sorption processes on pyrophyllite, gibbsite, and montmorillonite over extended time periods (min-months). The kinetic investi

Concentration and annealing effects on photoluminescence and local structure of Er-implanted silica

Autor: A.M. Vredenberg, Matthew A. Marcus, Geraldine M. Lamble, Dale C. Jacobson

Publikováno v: Journal of Non-Crystalline Solids. 195:232-238

Extended X-ray absorption fine structure (EXAFS) and photoluminescence (PL) measurements were performed on Er-implanted silica as a function of concentration and annealing at 900°C for 30 min. Er was implanted at 5 MeV to form peaked concentration p
