Modification of the Chemisorption Properties of Epitaxial Delafossite CuFeO2 Thin Films by Substituting Fe for Ga in the Crystal Structure
(2018)
Films of CuFeO2 and CuFe0.75Ga0.25O2 were grown over sapphire substrates in high vacuum using a pulsed laser deposition technique. The films grew with rhombohedral delafossite structure and highly epitaxial in the c-direction. ...
Estimation of residual stresses in perovskite films for capacitor applications
(2018)
The performance of perovskite films in capacitor devices is strongly determined by the level of residual stresses developed after their fabrication at high temperatures. Quantification of these stresses by X-ray diffraction ...
Characterization of pigments and binders in a mural painting from the Andean church of San Andres de Pachama (northernmost of Chile)
(2018)
The Andean church of San Andres de Pachama is located in the highland of the northernmost of Chile, near the limit with Bolivia and next to the Ruta de la Plata. This commercial route contributed in the past to the transport ...
Study of Aggregation of Gold Nanoparticles in Chitosan
(2018)
In this work it is reported the synthesis of gold nanoparticles supported in situ in chitosan by solvated metal atom dispersion technique in order to study the inclusion of Au nanoparticles in the biopolymer matrix. To ...
Ceramics fillers enhancing effects on the dielectric properties of poly (vinylidene fluoride) matrix composites prepared by the torque rheometer method
(2019)
The dielectric properties of ceramic-polymer composites were investigated using different lead-free ferroelectrics, 0.50[Ba(Zr0.2Ti0.8)O3]–0.50(Ba0.7Ca0.3)TiO3 (BZT-BCT) and 0.96(K0.48Na0.52) Nb0.95Sb0.05) O3–0.04Bi0.5(N ...
Titania coatings on high and low surface area spherical silica particles by a sol-gel method
(ROYAL SOC CHEMISTRY, 2000)
Spherical particles of porous silica were coated with titania by the sol-gel method starting from titanium isopropoxide. The silica samples used were of high and low surface area (about 250 and 19 m(2) g(-1), respectively). ...
