Herein we propose a novel approach to the preparation of quasi-1D nanostructures with various chemical compositions based on infiltration of colloidal solution into the asymmetric anodic alumina membrane. The proposed technique was successfully applied for the preparation of ordered arrays of the magnetically hard anisotropic hexaferrite nanostructures.

The International Programme on Chemical Safety (IPCS), established in 1980, is a joint venture of the United Nations Environment Programme (UNEP), the International Labour Organization (ILO), and the World Health Organization (WHO). The overall objectives of the IPCS are to establish the scientific basis for assessment of the risk to human health and the environment from exposure to chemicals, ...

In this paper, a microstrip patch mounted on high impedance substrate with hexaferrite cavity is proposed. The proposed antenna design is simulated on electromagnetic (EM) simulation software using FR-4 substrate with dielectric constant of 4.4 and thickness of 1.60mm. The proposed antenna has a compact structure with a total size of 50.8x50.8mm. A microstrip fed low profile broadband dielectri...

A number of solid solutions based on BaFe12?xTixO19 M-type barium hexaferrite doped with titanium cations up to x = 2.00 were obtained using conventional ceramic technology. The phase composition, crystal structure and unit cell parameters refined by the Rietveld method powder X-ray diffraction data T 900 K. It was found that all compositions have a magnetoplumbite satisfactorily described P63/...
