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 اولEntrapped chemically synthesized gold nanoparticles combined with polyethylene glycol and chloroquine diphosphate as an improved antimalarial drug
Objective(s): Drug delivery is an engineering technology to control the release and delivery of therapeutic agents to target organs, tissues, and cells. Metallic nanoparticles, such as gold nanoparticles (AuNPs) have exceptional properties which enable efficient drug transport into different cell types with reduced side effects and cytotoxicity to other tissues.Materials and Methods: AuNPs were...
متن کاملStructural 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 کاملUse of Polyethylene Glycol Coatings for Optical Fibre Humidity Sensing
Humidity induced change in the refractive index and thickness of the polyethylene glycol (PEG) coatings are in situ investigated for a range from 10 to 95%, using an optical waveguide spectroscopic technique. It is experimentally demonstrated that, upon humidity change, the optical and swelling characteristics of the PEG coatings can be employed to build a plastic fibre optic humidity sensor. T...
