ABSTRACT Polarized synchrotron emission from multiple Faraday depths can be separated by calculating the complex Fourier transform of Stokes’ parameters as a function wavelength squared, known Synthesis. As commonly implemented, introduces an additional term $\lambda _0^2$, which broadens real and imaginary spectra but not amplitude spectrum. We use idealized tests to investigate whether inform...

The synthesis and analytical applications of the new heterocyclic ligand are described. The complexation reaction of the ligand with some cations was studied in aqueous methanol at room temperature using the spectrophotometric method. Results revealed that only the absorption spectra of the Fe (III)–ligand complex show a high redshift of the absorption maximum in the aqueous methanol soluti...

5-((4-alkoxyphenyl)azo)salicyladehyde, 5-((4-alkoxyphenyl)azo)-N-(npentyl, ndodecyl)-salicyladimine and bis [5-((4-alkoxyphenyl)azo)-N-(npentyl, ndodecyl)-salicyladiminato]copper(II) [alkoxy=OnCnH2n+1; n=3-7] homologues were synthesized and characterized by elemental analyses, mass and IR spectra. All complex homol...

The reflection, transmission spectra and the polarization transformation of linearly polarized waves in the ferrite-semiconductor multilayer structure are considered. In the long-wavelength limit, the effective medium theory is applied to describe the studied structure as a uniaxial anisotropic homogeneous medium defined by the effective permittivity and effective permeability tensors. The inve...

Proton exchange membranes (PEM) for a direct methanol fuel cell (DMFC) have main drawbacks which are methanol permeability, reduced proton conductivity and the cost of the membrane. This paper reviews different polymeric materials such as fluorinated, non-fluorinated, acid-base complex, and composite membranes for DMFC. Currently, nonfluorinated membranes gain a lot of atte...

In this article, a systematic procedure to derive equivalent circuit networks accurately reproducing the frequency response of input impedance magnetic cores in broad range is presented. The proposed foresees represent effective complex permeability spectra core (i.e., resulting from superposition intrinsic material properties and effects due structural features core) by high-order Debye series...

The paper presents the results of a study phase composition and main static magnetic characteristics: saturation magnetization, residual magnetization coercive force polycrystalline ferroxplana type hexaferrites Ba2Ni2-xCuxFe12O22 (0 ≤ x 2.0) system. These materials have high permeability are promising for use as substrates antennas radar absorbing materials. It is shown that thermograms initia...

Complex conductivity measurements of carbonate rocks are scarce despite the occurrence these at surface Earth. The complex spectra 57 samples were measured in a broad frequency range and four salinities (NaCl). A simple model induced polarization is developed to be applied field. in-phase (related conduction) reported as function pore water determine (intrinsic) formation factor conductivity. n...

A new tris-chelate Cd(II) complex, [Cd(DADMBTZ)3](ClO3)2 has been successfully synthesized and characterized by IR, 1H, 13C NMR spectroscopy, elemental analysis and single crystal X-ray determination. The thermal behavior, UV-Vis and fluorescence spectra of compound were studied. In reaction with DADMBTZ, Cadmium (II) forms a tris-chelate complex with nearly C3 symmetry for coordination polyhed...
