Assessment of a bridge in Ensenada, Buenos Aires Province, Argentina
(Universidad Tecnológica Nacional, 2017-01)
The bridge over the mouth of Villa Elisa cannel, in the city of Punta Lara (Ensenada district, Buenos Aires Province, Argentina) was built during the 70´s decade and is located on the margin of Río de La Plata in an area ...
Transparent polysilsesquioxane films obtained from bridged ureasil precursors: Tunable photoluminescence emission in the visible region and filtering of UV-radiation
(Wiley VCH Verlag, 2010-11)
Bridged ureasil precursors were synthesized by the reaction of either ethylenediamine (1 mol) or m-xylylenediamine (1 mol) with isocyanatepropyltriethoxysilane (2 mol). Transparent polysilsesquioxane films were obtained ...

Photoluminescence of bridged silsesquioxanes containing urea or urethane groups with nanostructures generated by the competition between the rates of self-assembly of organic domains and the inorganic polycondensation
(American Chemical Society, 2006-05)
The aim of this study was to investigate the changes produced in the nanostructures and the photoluminescence spectra of bridged silsesquioxanes containing urea or urethane groups, by varying the relative rates between the ...
