TiO2 - SiO2 mixed oxides prepared by a combined sol-gel and polymer inclusion method
(2004)
Titania–silica mixed oxides were prepared by the sol–gel method from tetraethylorthosilicate (TEOS) and titanium (IV) isopropoxide (TTIP) as precursors. This paper reports the preparation of mixed oxides of different ...
Actividad antimicrobiana de nanopartículas de TiO2 en Serratia Marcescens y Eschericia Coli
La radiación solar, principalmente, los rayos UVA y UVB son una de las principales causas de cáncer en la piel, comúnmente, las cremas con protección solar usan moléculas inorgánicas como el TiO2, sin embargo, por su ...
Piezoelectric response and electrical properties of Pb(Zr1-xTix)O3 thin films: The role of imprint and composition
(2017-10-28)
The compositional dependence of the piezoelectric properties of self-polarized PbZr1-xTixO3 (PZT) thin films deposited on Pt/TiO2/SiO2/Si substrates (x = 0.47, 0.49 and 0.50) was investigated by in situ synchrotron X-ray ...
Geochemistry and Sr, Nd, Pb isotopic composition of the Central Atlantic Magmatic Province (CAMP) in Guyana and Guinea
(ELSEVIER SCIENCE BV, 2005-06)
The Central Atlantic Magmatic Province (CAMP) is one of the largest igneous provinces on Earth, extending more than 5000 km north to south, on both sides of the Atlantic Ocean. Its emplacement occurred about 200 Ma ago, ...
Temperature and stoichiometry effect on microstructural and ferroelectric properties of Pb(Zr1-xTix)O3 thin films prepared by chemical soulution deposition
(2004-05-10)
Lead zirconate titanate (PZT) solutions were prepared using a polymeric precursor method, Zr n-propoxide and Ti i-propoxide were used as starting materials with ethylene glycol and water as solvents. The PZT solution was ...
