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 اولPreparation of periodic surface structures on doped poly(methyl metacrylate) films by irradiation with KrF excimer laser
In this work, we describe laser modification of poly(methyl methacrylate) films doped with Fast Red ITR, followed by dopant exclusion from the bulk polymer. By this procedure, the polymer can be modified under extremely mild conditions. Creation of surface ordered structure was observed already after application of 15 pulses and 12 mJ cm(-2) fluence. Formation of grating begins in the hottest p...

the purpose of the present study was to investigate the relationship between fear of negative evaluation (fne) and communication strategies (css) among iranian efl learners. it was aimed to examine the differences in the use of communication strategies between speakers with high or low degree of fear of negative evaluation. the current study was a case study consisting of 10 english learners at...
Characteristics of the surface layer of barium strontium titanate thin films deposited by laser ablation
Ba0.5Sr0.5TiO3 ~BST! thin films grown on Si by an in situ ultraviolet-assisted pulsed laser deposition ~UVPLD! technique exhibited significantly higher dielectric constant and refractive index values and lower leakage current densities than films grown by conventional PLD under similar conditions. X-ray photoelectron spectroscopy ~XPS! investigations have shown that the surface layer of the gro...
متن کاملCereal Biopolymer Films, Coatings and Other Industrial Products
Thermoplastic proteins can be prepared by using a suitable plasticizer and by using a proper combination of mechanical shear and heat. The amount of plasticizer and the processing conditions leads to materials with different chemical and physical properties which can be optimized to produce films, fibers and foams. The effect of type and amount of plasticizer, and the effect of processing condi...
