Particles of Cobalt ferrite, CoFe2O4-, were coated with polyaniline (PANI) sulphate and phosphate during in-situ polymerization of aniline in an aqueous solution of sulfuric and phosphoric acid. The PANI-ferrite composites were characterized by Fourier transform infrared (FTIR) spectroscopy. Structures and morphology of products were studied by X-Ray Diffraction (XRD) and Scanning Electron Micr...
Nanomagnetism is a branch of nanotechnology, which studies the magnetic properties of nanoparticles. Single-domain superparamagnetim, superferromagnetism and superspin glasses are different magnetic states which have been observed in a system of nanoparticles. Each of these magnetic states has unique features which determines the application range of magnetic nanoparticles assembly. Shell of na...
Under the Range Rule (1997), the Department of Defense defines unexploded ordnance (UXO) as a piece of ordnance that has been deployed, but has not exploded. This study investigated a subset of UXO including artillery shells and mortars (projectiles), but excluding landmines. UXO contaminates approximately 15 million acres of land in the United States alone. The geophysical tools most frequentl...
In this work we present preliminary results on magnetization and remanence of synthetic pseudo-binary x(Fe2TiO4)-(1x)(Fe3O4)(0.30<x<1.00). Magnetic characterization was performed at temperature ranges from 100 K up to 400 K. The final objective is to characterize the magnetic response as a function of temperature in order to foresight the future magnetic measurements of the magnetometer include...
