In this study, the effect of simultaneous doping of magnesium, calcium, and copper ions on the properties of zinc oxide doped with cobalt was investigated. The sol-gel method has been used for the synthesis of nanoparticles. The structural and optical properties of the synthesized nanoparticles were investigated using X-ray diffraction (XRD), infrared spectroscopy (FTIR), and DRS spectroscopy. ...
in this paper, the hartree-fock method has been formulated to investigate some of the ground state properties of quasi-one-dimensional interacting electron gas in the presence of the magnetic field. the bare coulomb interaction between electrons has been assumed. for this system, we have also computed some of its thermodynamic and magnetic properties such as the energy, pressure, incompressibil...
Recent studies on non-invasive recordings from human brain have shown the existence of tasteelicited activation areas in the cerebral cortex [1,2]. Magnetoencephalogram (MEG) is a popular instrument for these non-invasive measurement as well as functional MRI (f-MRI) and positron CT (PET). The advantage of MEG measurement is easy to analyze a time-course data as a function of taste-elicited inf...
superconducting materials are capable of trapping extremely high magnetic fields. this property and meissner effect of superconductors causes a levitation force between bulk superconductors and a permanent magnet (pm). this levitation force has possible industrial applications such as permanent magnet guideways (pmg). because of the high price of permanent magnets, the optimization of pmg desig...
In the design of the RF system of the JHF (Japan Hadron Facility) proton synchrotrons, it is very important to find a magnetic core to which satisfies the required condition of the JHF accelerators[1]. Ferrite cores are usually used for the magnetic core of the proton synchrotron, however there are some problems. Generally, some ferrite cores have non-linear characteristics which depend on the ...
bis-(l-tyrosinato)copper(ii) was reacted with 3-(chloropropyl)-trimethoxysilane functionalized silica that has infused magnetite to yield a magnetically separable catalyst in which the copper carboxylate is covalently linked to the silica matrix through the silane linkage. the immobilized catalyst has been characterized by spectroscopic studies (such as ft-ir, epr, magnetic measurement, sem) an...
The effect of surface functionalization with citric acid on the properties magnetic nanoparticles (MNPs) Zn x Fe 3-x O 4 (x=0; 0.25; 0.5; 0.75; 1.0) synthesized by hydrothermal method was studied. To study MNPs, X-ray diffractometry (XRD) and energy dispersive spectroscopy (EDS) were used. samples phase state MNPs studied using a physical property measurement system (PPMS) Mossbauer (MS). It ha...
alzheimer's disease (ad) is a progressive neurodegenerative disease characterized by memory and cognitive dysfunction due to neuronal cell loss in higher brain centers. senile plaques containing amyloid β (aβ) are associated with this disease as well as a reduction in cholinergic neuron numbers. tacrine is a reversible cholinesterase inhibitor in clinical use to treat moderate forms of ad. chit...
