Er3+/Yb3+ co-activated silica-alumina monolithic xerogels
(Kluwer Academic Publ, 2003-01-01)
Monolithic silica xerogels doped with different concentrations of Er3+, Yb3+ and Al3+ were prepared by sol-gel route. Densification was achieved by thermal treatment in air at 950degreesC for 120 h with a heating rate of ...

Sol-gel preparation of mesoporous Al2O3-SiO2 glasses: structural evolution monitored by solid state NMR
(SpringerNew York, 2014-06)
Glasses along the composition line 0.5Al2O3–xSiO2 (1 ≤ x ≤ 6) were prepared via a novel sol-gel route using tetraethylorthosilicate and aluminum lactate as precursors. The structural evolution from solution to gel to glass ...
Microtensile bond strength of composite resin to glass-infiltrated alumina composite conditioned with Er,Cr:YSGG laser
(SPRINGER LONDON LTDLONDON, 2012)
Tribochemical silica-coating is the recommended conditioning method for improving glass-infiltrated alumina composite adhesion to resin cement. High-intensity lasers have been considered as an alternative for this purpose. ...
Thermal decomposition of [M-3(CO)(12)] (M = Ru, Os) physisorbed onto porous Vycor glass: a route to a glass/RuO2 nanocomposite

Silica coating on alumina ceramic: comparison of three chairside air-abrasion devices working for different times and distances.
(2011-03-01)
This study evaluated, by scanning electron microscope (SEM) and EDS, the effect of different strategies for silica coating (sandblasters, time and distance) of a glass-infiltrated ceramic (In-Ceram Alumina). Forty-one ...
