Structure and luminescence of Eu3+-doped class I siloxane-poly(ethylene glycol) hybrids
(Amer Chemical Soc, 2001-09-01)
Transparent, flexible, and luminescent EU3+-doped siloxane-poly(ethylene glycol) (PEG) nanocomposites have been obtained by the sol-gel process. The inorganic (siloxane) and organic PEG phases are usually linked by weak ...

Study of structural surface modified tin oxide membrane prepared by sol-gel route sintered at 400 degrees C
(Kluwer Academic Publ, 2003-01-01)
This work describes the chemical modification by Tiron(R) molecules of the surface of SnO2 nanoparticles used to prepare nanoporous membranes. Samples prepared with Tiron(R) content between 1 and 20 wt% and fired at 400 C ...

Local atomic structure in tetragonal pure ZrO2 nanopowders
(Wiley Blackwell Publishing, Inc, 2010-04)
The local atomic structures around the Zr atom of pure (undoped) ZrO 2 nanopowders with different average crystallite sizes, ranging from 7 to 40 nm, have been investigated. The nanopowders were synthesized by different ...
Sintering and crystallite growth of nanocrystalline copper doped tin oxide
(Amer Chemical Soc, 1999-04-08)
The effect of Cu2+ contents and of firing temperature on sintering and crystallite growth of nanocrystalline SnO2 xerogels was analyzed by thermoanalysis (mass loss (TG), linear shrinkage, and differential thermal analysis ...
XANES study of electronic and structural nature of Mn-sites in manganese oxides with catalytic properties
(Elsevier Science, 2005-10)
The characterization of a series of manganese oxides prepared by different methods were performed by X-ray diffraction (XRD) and X-ray absorption near-edge structure (XANES) analysis. Low crystallized phases were found by ...
