Study of Electrical and Magnetic Properties of Praseodymium Samarium Doped Novel Magnesium Ferrite

wuthering heights and the concept of marality/a sociological study of the novel

to discuss my point, i have collected quite a number of articles, anthologies, and books about "wuthering heights" applying various ideas and theories to this fantastic story. hence, i have come to believe that gadamer and jauss are rightful when they claim that "the individaul human mind is the center and origin of all meaning," 3 that reading literature is a reader-oriented activity, that it ...

Synthesis of Magnesium Ferrite-Silver Nanostructures and Investigation of its Photo-catalyst and Magnetic Properties

In this research we first synthesized MgFe2O4 nanostructures via hydrothermal method using (Mg(NO₃)₂.6H₂O) and (Fe(NO₃)₃.9H₂O). The influence of concentration, surfactant, precipitating agent and temperature on the particle size and magnetic properties of the synthesised nanoparticles were examined. Then MgFe2O4-Ag nanocomposites were prepared by a simple chemical precipitation. The structural ...

Effect of cobalt on structural, microstructural and magnetic properties of magnesium-zinc ferrite nanoparticles

Mg0.5-xCoxZnFe2O4 ferrite nanostructures with various amounts of Co2+ substitution (x= 0, 0.05, 0.10, 0.15) were prepared using a simple and inexpensive sol-gel method sol-gel route. Structural, microstructural and magnetic properties of the prepared powders were investigated by x-ray diffraction (XRD), Fourier transform infrared (FT-IR), field emission- scanning electron microscopy (FE-SEM), X...

extraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties

آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
