[ 1 ] - سنتزو شناسایی نانو ذرات اکسید مس در ماتریس کانی- حفره ای با ساختار ناهمگن و بررسی خواص آنتی باکتریایی آن

این مطالعه آماده سازی و شناسایی ماتریس کانی - حفرهای با ساختار ناهمگن (PCH) به عنوان یک بستر با مساحت سطح بالا برای نانوذرات مس اکسید و عملکرد آنتی باکتریایی آن در برابر باکتری های گرم مثبت و منفی گزارش میکند. نانوذرات مس اکسید به روش تجزیه حرارتی درون بستر PCH قرار گرفتند و به وسیلهی اسپکتروسکوپی بازتابش انتشاری (DRS)، پراش پرتو ایکس (XRD)، اسپکتروسکوپی تبدیل فوریه- مادون قرمز (FT-IR)، اندازه ...

[ 2 ] - Nanodimensional AlMCM-41 material for adsorption of dyes: Thermodynamic and kinetic studies

AlMCM-41 was applied for adsorption of methylene blue (MB) and auramine (AU) in single and binary component systems. In the single component systems, AlMCM-41 represents higher adsorption capacity for MB than AU with the maximal adsorption capacity of 2.07×10−4 and 1.15×10−4 mol/g at 25 ˚C for MB and AU, respectively. In the binary component system, MB and AU exhibit compe...

[ 3 ] - A cost effective and sensitive method for the determination of ammonia concentration in nanocrystal mordenite

The reduction capacity of ammonia while present even at ppm level can be demonstrated by the increased encounter probability between ammonia and methylene blue dye (MB+) incorporated in nanomordenite and Na-MOR zeolites. The rate of reduction methylene blue dye by ammonia on the surface nanomordenite zeolite is faster than Na-mordenite (Na-MOR) zeolite.Because nanomordenite zeolite with high si...

[ 6 ] - Antibacterial Activity of Mesoporous Silica Nanofibers

In this research, the fabrication of MCM-41 mesoporous material nanofibers by an electrospinning technique was performed. The MCM-41 nanofibers (MCM-41 NFs) as a novel host on the incorporation of silver has been studied in [Ag(NH3)2]NO3 precursor solution through the heat-treatment process. The formation of silve...
