synthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
15 صفحه اولSynthesis, optical and structural characterization of CdS nanoparticles
Cadmium sulfide nanoparticles were grown using wet chemical method by dissolving the reactants of cadmium acetate and sodium sulfide in the presence of thioglycerol (TG) as capping agent in ethanol solvent. Different nanoparticle sizes and size distribution were obtained through varying the molarities of thioglycerol. At higher TG concentration, synthesis provides a nearly monodisperse nanopart...
متن کاملStructural and Magnetic Investigations on FePt Nanoparticles
Magnetic nanoparticles and thin films exhibiting a large magnetic anisotropy energy density (MAE) have attracted enormous attention over the last years due to their potential use in magnetic data storage or sensing applications. FePt alloy nanoparticles and films have a huge MAE in the chemically ordered L10 phase. This ordered phase is typically obtained by annealing the as-prepared chemically...
متن کاملStructural studies of L10 FePt nanoparticles
We have studied the lattice parameter changes of L10 FePt nanoparticles annealed to near equilibrium as a function of composition by x-ray diffraction. We have found that the ~111! diffraction peak shifts linearly with composition, however, the c parameter mostly changes in the Pt rich compositions and the a parameter mostly changes in the Fe rich compositions with respect to the equiatomic com...
متن کاملPolyol Process Synthesis of Monodispersed FePt Nanoparticles.
Monodispersed FePt nanoparticles are synthesized by reduction of iron(II) acetylacetonate and platinum(II) acetylacetonate with 1,2-hexadecanediol as the reducing reagent in the polyol process. As-prepared FePt nanoparticles are chemically disordered with fcc phase. Transmission electron microscopy (TEM) images show a self-assembled particle array with an average particle size of 3 nm and a sta...
