Raghvendra Singh Yadav,Ivo Kuřitka,Jarmila Vilčáková,Jaromir Havlica,Jiri Masilko,Lukáš Kalina,Jakub Tkacz,Jiří Švec,Vojtěch Enev,Miroslava Hajdúchová +9 more
Journal ArticleDOI
Structural, magnetic, dielectric, and electrical properties of NiFe2O4 spinel ferrite nanoparticles prepared by honey-mediated sol-gel combustion
Raghvendra Singh Yadav,Ivo Kuřitka,Jarmila Vilčáková,Jaromir Havlica,Jiri Masilko,Lukáš Kalina,Jakub Tkacz,Vojtěch Enev,Miroslava Hajdúchová +8 more
TL;DR: In this paper, a honey-mediated sol-gel combustion method was used to synthesize NiFe2O4 nanoparticles and samples annealed at 800 and 1100°C were characterized by X-ray diffraction and Raman spectroscopy.
Journal ArticleDOI
Structural, dielectric, electrical and magnetic properties of CuFe2O4 nanoparticles synthesized by honey mediated sol–gel combustion method and annealing effect
Raghvendra Singh Yadav,Ivo Kuřitka,Jarmila Vilčáková,Jaromir Havlica,Jiri Masilko,Lukáš Kalina,Jakub Tkacz,Miroslava Hajdúchová,Vojtěch Enev +8 more
TL;DR: In this paper, the authors used powder X-ray diffraction, Raman spectroscopy, Fourier Transform Infrared Spectroscopy (FTIS), Scanning Electron Microscopy (SEM), Energy Dispersive x-ray Spectrography (EDX-Spectrograph), and Xray Photoelectron Spectrogram (XP-Spectrogram) to analyze the properties of the CuFe2O4 nanoparticles synthesized by a sol-gel auto-combustion method.
Journal ArticleDOI
Some Issues of Shrinkage-Reducing Admixtures Application in Alkali-Activated Slag Systems
TL;DR: Observations proved the certain incompatibility of SRA with the studied AAS system, because the drying shrinkage reduction was induced by the strong retardation of hydration, resulting in a coarsening of the pore structure rather than the proper function of the SRA.
Journal ArticleDOI
Comparison of Electrochemical Methods for the Evaluation of Cast AZ91 Magnesium Alloy
TL;DR: The corrosion current density obtained by cathodic polarization was similar to the corrosion currentdensity obtained by linear polarization, while a lower value was obtained by anodic polarization.
