Degradation of Phenol in Water by Titanium Dioxide Photocatalysis
The photocatalytic degradation of phenol in a static-batch photoreactor, using a UV lamp as a light source and TiO 2 as a photocatalyst, was investigated. The effects of various parameters, such as photocatalyst dosage, initial substrate concentration, reaction pH and addition of oxidants, on the phenol degradation rate of TiO 2 photocatalysis were examined. The degradation rates proved to be s...
متن کاملcontrol 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 اولA Characteristic-based Numerical Simulation of Water-titanium Dioxide Nano-fluid in Closed Domains
A new characteristic-based method is developed and used for solving the mixed and forced convection problems. The nano-fluid flow with heat transfer is simulated with a novel characteristic-based scheme in closed domains with different aspect ratios. For this purpose, a FORTRAN code has been written and developed. Water as a pure fluid and water-titanium dioxide as a nano-fluid were considered....
متن کاملGrowth of titanium dioxide nanorods in 3D-confined spaces.
Three-dimensional (3D) nanowire (NW) networks are promising architectures for effectively translating the extraordinary properties of one-dimensional objects into a 3D space. However, to uniformly grow NWs in a 3D confined space is a serious challenge due to the coupling between crystal growth and precursor concentration that is often dictated by the mass flow characteristic of vapor or liquid ...
متن کاملDetermination of Lead and Cadmium in cow’s Milk and Elimination by Using Titanium Dioxide Nanoparticles
Background and Objectives: Heavy metals such as cadmium and lead are the most important toxins spreading through various ways like water, soil, and air in nature and easily enter human food chain. It is essential to determine the cumulative and harmful effects of these metals in nutrients, especially in cow milk because it is a unique source of food for all ages and it contains both essential a...
