Abstract The formulation of polymer with embedded magnetic nanoparticles results in promising nanocomposites for smart and analytical applications. Nanocomposites containing polyacrylonitrile (PAN) different mass contents strontium hexaferrite (SFO) were prepared using the casting method. nanocomposite samples characterized by techniques such as field-emission scanning electron microscopy, Four...
In this paper, nanoparticles of M- type strontium hexaferrite doped with cobalt SrFe12-xCoxO19 (x= 0-2) were synthesized via sol– gel technique. Structural and morphological properties of the samples were analyzed by X- ray diffraction (XRD), Fourier transform infrared spectroscopy (FT- IR) and scanning electron microscopy (SEM). The XRD results showed that all of the samples of SrFe12-xCoxO19 ...
Abstract The development of hexaferrite nanoparticles is scrutinized as potential sorbents for the removal chromium (Cr) ions from aqueous chromium-containing solutions in a batch adsorption experiment. transition metal Co doped BaFe 12 O 19 compounds (BHF) have been synthesized successfully via citrate auto combustion technique. structure, surface morphology and magnetic properties samples wer...
the present study investigated construct equivalence of multiple choice (mc) and constructed response (cr) item types across stem and content equivalent mc and cr items (item type ‘a’), non-stem-equivalent but content equivalent mc and cr items (item type ‘b’), and non-stem and non-content equivalent mc and cr items (item type ‘c’). one hundred seventy english-major undergraduates completed mc ...
