[ 1 ] - ساخت نانوذرات مغناطیسی اکسیدآهن به روش همرسوبی و بررسی تاثیر نسبت غلظت مواد واکنش دهنده بر اندازه و خواص مغناطیسی ذرات
در این مقاله نانوذرات اکسیدآهن به روش همرسوبی و با استفاده از NaOH به عنوان عامل رسوب‌دهنده سنتز شده است. خواص مغناطیسی ذرات توسط VSM اندازه‌گیری و تاثیر غلظت مواد واکنش دهنده بر خواص مغناطیسی و اندازه نانوذرات بررسی شده است. اندازه ذرات با استفاده از الگوهای اشعه X به کمک فرمول شرر و همچنین با استفاده از داده-های مغناطیسی محاسبه و با اندازه TEMمقایسه شده است. اندازه ذرات بدست آمده بین 8 الی 12...
[ 2 ] - Applying a suitable route for preparation Fe3O4 nanoparticles by Ammonia and investigation of their physical and different magnetic properties
Iron oxide nanoparticles were synthesized by coprecipitation method using ammonia as precipitation agent. Most researchers usually add ammonia into the iron salt solution but in this work the salt solution drop wise has been added to the ammonia and the new obtained results were compared with those of other researches. Magnetic properties of nanoparticles were measured by VSM. The effect of rea...
