Distributed feedback multipeak laser emission in Rhodamine 6G doped organic-inorganic hybrids
(Springer, 2006-12-01)
Organic-inorganic hybrid materials were prepared from an ureasil precursor (ureapropyltriethoxysilane designated as UPTES) and acrylic acid modified zirconium (IV) n-propoxide. Thin films containing rhodamine 6G (Rh6G) ...

Bacterial cellulose-silica organic-inorganic hybrids
(Springer, 2008-06-01)
Bacterial cellulose (BC) hydrated membranes present nanometric reticulated structure that can be used as a template in the preparation of new organic-inorganic hybrids. BC-silica hybrids were prepared from BC membranes and ...
Electrochemical Determination of Inorganic Contaminants in Automotive Fuels
(Wiley-v C H Verlag Gmbh, 2012-08-01)
This article critically reviews the electroanalytical methods developed for the determination of inorganic contaminants in automotive fuels. Topics include the methods applied to the analysis of liquid biofuels and liquid ...
Self-supported bacterial cellulose/boehmite organic-inorganic hybrid films
(Springer, 2012-08-01)
Self-supported organic-inorganic hybrid transparent films have been prepared from bacterial cellulose and boehmite. SEM results indicate that the BC membranes are covered by Boehmite and XRD patterns suggest structural ...
Photoluminescence of bulks and thin films of Eu3+-doped organic/inorganic hybrids
(Elsevier B.V. Sa, 2008-02-28)
Organic-inorganic hybrids formed by polyether-based chains grafted to both ends to a siliceous backbone through urea cross-linkages (-NHC=O)NH-), named di-ureasil, have been used as host for incorporation of Eu3+ in the ...
