[ 1 ] - A Comparative Study of the Synthesis and Thermal Stability of Nanostrucrured Al and Al-Mg Powders Fabricated by Mechanical Alloying Technique
Nanostructured Al and Al-Mg (Mg 30 wt. %) powders with the mean crystallite sizes of 42 and 11 nm were prepared through the solid state ball milling technique. The milling process was performed for various times up to 12 h in argon atmosphere and the synthesized powders were in detail characterized by different techniques. The effect of milling time and Mg addition on the size, morphology, chem...
[ 2 ] - Synthesis and characterization of the electrospun fibers prepared from waste polymeric materials
Recently, the demands for the production of many different types of plastic wastes are greatly growing that subsequently, lead to the serious challenges in environmental considerations. Since, these materials are rarely resolved by microorganisms, hence, their recycling to the useful materials is crucial. In the present study, we used a solution electrospinning technique to synthesize nano/micr...

[ 4 ] - سنتز و بررسی رفتار مغناطیسی نانوکامپوزیت مگنتیت– نانولوله‌های کربنی (Fe3O4-CNTs) به‌منظور کاربرد در نانوسیالات مغناطیسی بر‌پایه آب
در این تحقیق، نانوکامپوزیت مگنتیت بر‌پایه نانولوله‌های کربنی (Fe3O4-CNTs) با استفاده از روش سولوترمال سنتز شد. ساختار نانوکامپوزیت Fe3O4-CNTs توسط آنالیزهای متنوع از جمله میکروسکوپ الکترونی عبوری (TEM)، پراش اشعه ایکس (XRD)، اشعه مادون قرمز تبدیل فوریه (FTIR)، مگنتومتر (VSM) و پتانسیل زتا (Zeta Potential) مورد مشخصه‌یابی قرار گرفت. بر‌اساس نتایج TEM و XRD اندازه ذرات و بلورک‌های مگنتیت، به‌ترتی...
