Homogenization in Nonlinear Chemical Reactive Flows
The goal of this paper is to study a nonlinear model for some chemical reactive flows involving diffusion, adsorption and chemical reactions which take place at the boundary and also in the interior of a periodically perforated material. The effective behavior of such flows is governed by another nonlinear boundary-value problem, which contains extra zero-order terms and captures the effect pro...
متن کاملCharacteristic Effects in the Reaction Kinetics of Polymeric Reagents
Recent advances in studies of the kinetics of chemical processes in dilute polymer solutions include in— vestigations of hindered rotation in the backbone of flexible chain molecules, of ionic reactions in polyelectrolyte solu— tions, kinetic effects reflecting the local medium in the polymer domain, neighboring group effects in reactiorof polysaccharides and diffusion—controlled intramolecular...
متن کاملSustained Release of Naproxen in a New Kind Delivery System of Carbon Nanotubes Hydrogel
In this paper, carbon nanotubes (CNTs) were added into chitosan (CS) hydrogels in the form of chitosan modified CNTs (CS-CNTs) composites to prepare carbon nanotubes hydrogels (CNTs-GEL). The products, named CS-MWCNTs, were characterized by scanning electron microscope (SEM) and Fourier transform infrared (FTIR) spectroscopy. Swelling properties and effect of pH on controlled release performanc...

متن کاملDecolorization of a Reactive Dye by UV-Enhanced Ozonation
In the present study the treatment efficiency of O3 and UV+O3 processes were compared for the oxidation of simulated dyebath effluent containing a mixture of a reactive dye (C.I. Reactive Blue 19) and various dye auxiliary chemicals. The color, COD and TOC removal rates were assessed for different processes. The effect of initial dye concentration and presence of sodium hydroxide and sodium car...
