control of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولStructural and Optical Properties of Gold Nanoparticles Formed by Wet-Chemical Method
Our aim in this work is the synthesis and study optical and structural properties of gold nanoparticles.Gold (III) chloride trihydratewas taken as metal precursor, ascorbic acid at the presence of an appropriate amount of NaOH as reducing agent and polyvinylpyrrolidonek-30 (PVP K-30) as a stabilizing and capping agent. The reaction was performed in high-speed stirring rate at room temperature.S...

متن کاملFractionation and Determination of Some Structural Properties of Persian Gum
ABSTRACT: In the present study, Persian gum, an exudate gum which secrets from the mountain almond tree (Amygdalus scoparia Spach) from two different regions is evaluated by means of chemical and instrumental analysis (fractionated by solving in water and alkaline solutions at 0.1, 0.5 and 1 M and also Smith degradation) using HPLC, 1H–NMR and 13C–NMR spectroscopy’s. The total sugar and uronic ...
