Observation of superficial antiferromagnetism in Co3O4 polycrystals Abstract: We report on a systematic study about the magnetic properties of Co3O4 polycrystals with large size distribution (100-1200 nm) and the crystallite size of 68(4) nm on average. […]
Pigments based on Cr and Sb doped TiO2prepared by microemulsion-mediated solvothermal synthesis for inkjet printing on ceramics Abstract:A ceramic pigment with nominal composition Ti0.97Cr0.015Sb0.015O2 was prepared by microemulsion-mediated solvothermal method at 180 degrees C. Anatase […]
Antiferromagnetism induced by oxygen vacancies in V2O5 polycrystals synthesized by the Pechini method Abstract: Optical and magnetic properties of V2O5 polycrystals were investigated through photoluminescence (PL) and magnetization measurements. The PL spectra comprise two main bands […]
Application of oxo-manganese complex immobilized on ion-exchange polymeric film as biomimetic sensor for nitrite ions Abstract: A biomimetic sensor based on oxo-bridged dinuclear manganese-phenanthroline complex immobilized into an ion-exchange polymeric film deposited on glassy carbon electrode […]
Formation and evolution of TiO2 nanotubes in alkaline synthesis Abstract: One-dimensional nanostructures have been intensively studied, from the point of view of their synthesis and mechanics of formation, as well as their applications. Titanium dioxide nanoparticles […]
Far-infrared spectroscopic study of CeO2 nanocrystals Abstract: We present the far-infrared reflectivity spectra of 5 nm-sized pure and copper-doped Ce1−x Cu xO2−y (x = 0; 0.01 and 0.10) nanocrystals measured at room temperature in the 50–650 cm−1spectral range. Reflectivity spectra were analyzed using […]
Rietveld refinement and optical properties of SrWO4:Eu3+ powders prepared by the non-hydrolytic sol-gel method Abstract: We investigated the effect of annealing time on the structure and optical properties of SrWO4:Eu3+ powders prepared by the non-hydrolytic sol-gel method […]
Rapid hydrothermal synthesis and pH-dependent photocatalysis of strontium titanate microspheres Abstract: This manuscript describes a methodology for a rapid hydrothermal conventional synthesis of SrTiO3. The time of synthesis and use of mechanical stirring are related to […]
Light emission during electric field-assisted sintering of electroceramics Abstract: Electric field-assisted sintering has been shown to occur in ion, electron conducting as well as in insulating polycrystalline ceramics. Considerable linear shrinkage with microstructure control at temperatures lower than […]
