Static and dynamic magnetic properties of Co2Z barium ferrite nanoparticle composites
The static, dynamic and attenuation properties of Co2Z barium ferrites and Co2Z composites have been studied. The results showed that both static and dynamic magnetic properties are significantly different for large particles and nanoparticles. As compared to large particles, Co2Z nanoparticles have a small saturation magnetization Ms , large coercivity Hc , small permeability μ0 and μ ′′ max, ...
متن کاملMagnetic and Electrical Properties of Nanocrystalline Fe85Si10Ni5/Phenolic Resin Soft Magnetic Composites
In this work, nanocrystalline Fe85Si10Ni5 soft magnetic powders were prepared by mechanical alloying and subsequent annealing to reduce the internal stresses and lattice strains. The powders were mixed with phenolic resin and warm pressed to produce nanostructured soft magnetic composites. The effect of annealing time and temperature on the crystalline structure, microstructure and magnetic pro...

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 ...
15 صفحه اولCOMPARATIVE MAGNETIC AND PHOTOCATALYTIC PROPERTIES OF COPRECIPITATED ZINC FERRITE NANOPARTICLES BEFORE AND AFTER CALCINATION
In this work, the effects of co-precipitation temperature and post calcination on the magnetic properties and photocatalytic activities of ZnFe2O4 nanoparticles were investigated. The structure, magnetic and optical properties of zinc ferrite nanoparticles were characterized by X-ray diffraction (XRD), vibrating sample magnetometry and UV–Vis spectrophotometry techniques. The XRD re...
متن کاملEffect 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...
