extraction and characterization of allium irancum plant extract and its application in the green synthesis of silver nano particles and oxidation of thiocarbony1 compounds
سنتز سبز نانوذرات فلزی (nps) درسالهای اخیر توجه بسیارزیادی را به خود جلب کرده است. زیرا این پروتوکل کم هزینه وسازگار با محیط زیست از روش های استاندارد سنتز. در این پایان نامه ما گزارش میکنیم یک روش ساده و سازگار با محیط زیست برای سنتز نانوذرات نقره با استفاده از محلول آبی عصاره گیاه allium iranicum به عنوان یک عامل کاهش دهنده ی طبیعی. نانو ذرات نقره مشخص شد با استفاده از تکنیک های uv-visible، x...

15 صفحه اولUltrabright fluorescent mesoporous silica particles
Recent self-assembly of ultra-bright fluorescent colloidal mesoporous (nanoporous) silica particles is highlighted. The particles can be up to two others of magnitude brighter than polymeric particles of comparable size assembled with quantum dots. Comparing with the maximum fluorescence of free dye in the same volume, the particles can show fluorescence which is higher by more than three order...
متن کاملBackscattered electron (BSE) imaging of platinum nano-particles dispersed in mesoporous silica.
High-resolution scanning electron microscopy (HR-SEM) with backscattered electrons (BSE) under a low accelerating voltage provided images with compositional information about Pt nano-particles with a diameter of approximately 6 nm that were dispersed in mesoporous silica (SBA-15). The dispersion of Pt nano-particles in mesoporous silica was investigated using the BSE imaging method in combinati...
متن کاملComposite particles of polyethylene @ silica.
Polyethylene (PE) and silica are perhaps the simplest and most common organic and inorganic polymers, respectively. We describe, for the first time, a physically interpenetrating nanocomposite between these two elementary polymers. While polymer-silica composites are well known, the nanometric physical blending of PE and silica has remained a challenge. A method for the preparation of such mate...
