Adsorption properties of organic compounds by thermosensitive polymer.

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...

Adsorption of Volatile Organic Compounds from Aqueous Solution by Granular Activated Carbon (GAC) in Batch System

Removal of chlorinated volatile organic compounds by fixed bed adsorption technique: Adsorption equilibrium and breakthrough analyses

The adsorption equilibrium and dynamic breakthrough behaviour of chlorinated volatile organic compounds (CVOCs), namely chloroform and carbon tetrachloride, were experimentally investigated by using pelleted activated carbon in a fixed bed. The experimental studies were carried out at atmospheric pressure, the temperature of 313 K, the gas flow rate of 3 L/min and various inlet gas phase concen...

Solvent-dependent critical properties of polymer adsorption.

Advanced chain-growth computer simulation methodologies have been employed for a systematic statistical analysis of the critical behavior of a polymer adsorbing at a substrate. We use finite-size scaling techniques to investigate the solvent-quality dependence of critical exponents, critical temperature, and the structure of the phase diagram. Our study covers all solvent effects from the limit...

Magnetic Nanoparticles Coated with a Thermosensitive Polymer with Hyperthermia Properties

Magnetic nanoparticles (MNPs) have been widely used to increase the efficacy of chemotherapeutics, largely through passive accumulation provided by the enhanced permeability and retention effect. Their incorporation into biopolymer coatings enables the preparation of magnetic field-responsive, biocompatible nanoparticles that are well dispersed in aqueous media. Here we describe a synthetic rou...
