Conductance model for single-crystalline/compact metal oxide gas-sensing layers in the nondegenerate limit: Example of epitaxial SnO2(101)
(American Chemical Society, 2019-09)
Semiconducting metal oxide (SMOX)-based gas sensors are indispensable for safety and health applications, for example, explosive, toxic gas alarms, controls for intake into car cabins, and monitor for industrial processes. ...
A new synthesis pathway for colloidal silica spheres coated with crystalline titanium oxide and its comparative cyto- and genotoxic study with titanium oxide nanoparticles in rat osteosarcoma (UMR106) cells
(Elsevier Science, 2013-03)
Spherical particles with an amorphous core of silica and a crystalline shell of titanium oxide (SiO2@TiO2) formed in a three-step procedure, being the last step a mild chemical treatment. SiO2@TiO2 had a shell with pores ...
Characterization of anodic growth and dissolution of antimony oxide films
(Elsevier Science Sa, 2009-07)
The anodic growth, morphology and stability of antimony oxide films grown in buffered phosphate electrolytes has been characterized by electrochemical methods, in situ ellipsometry and atomic force microscopy. The anodic ...
Miscibility and mechanical properties of an amine-cured epoxy resin blended with poly (ethylene oxide)
(John Wiley & Sons Ltd, 2007-12)
Blends composed of diaminodiphenylmethane bisphenol‐A epoxy resin and poly(ethylene oxide) (PEO) were prepared via in situ curing reaction of epoxy in the presence of PEO. The miscibility of the blends before and after ...
Factors affecting phosphorus sorption in loess soils of the semiarid Argentina
(Pisa University Press, 2000-08)
Previous results showed that phosphorus sorption strongly correlated with contents of active Al and Fe oxides and organic matter (OM) in soils of the-Semiarid Argentinean Pampas. Objective of this study was to determine ...
Thickness dependence of crystalline structure of Al-doped ZnO thin films deposited by spray pyrolysis
(Elsevier, 2015-07)
In this work, we have investigated the influence of thickness on crystalline structure of Al-doped ZnO films. Transparent conducting oxide films were grown by the spray pyrolysis technique from precursors prepared via the ...
Effect of transition metal doping on the crystal structure and oxidation state of Sr2MgMo0.9TM0.1O6− compounds (TM = Co, Mn or Ni)
(Pergamon-Elsevier Science Ltd, 2019-12)
We analyse the effects of the partial replacement of Mo by transition metals (Co, Mn or Ni) on the electronic and structural properties of Sr2MgMo0.9TM0.1O6−δ (SMMTM; TM is Co, Mn or Ni) compounds. The crystal structure ...
Mesoporous thin film structures as metal nanoparticle reactors for electronic circuits: Effects of matrix crystallinity and nanoparticle functionalization
(Academic Press Ltd - Elsevier Science Ltd, 2017-09)
There is an increasing interest in versatile nanoelectronic structures based on stable, accessible and spatially located arrays of metal nanoparticles. In this study, the influences of mesoporous titania thin film crystallinity ...
Influence of silver electrochemically deposited onto zinc oxide seed nanoparticles on the photoelectrochemical performance of zinc oxide nanorod films
(SAGE Publications, 2019-05)
The present article examines the synthesis and characterization of zinc oxide nanorods grown on zinc oxide and silver nanoparticle seeds. Zinc oxide seeds were electrodeposited on a support of fluorine-doped tin oxide glass ...
