Regularities of the phase protective layer formation in multicomponent systems involving inhibitors with different mechanism of protective action have been investigated. It was shown that optimization of the composition of the inhibition mixture allows to obtain higher protective efficiency owing to improved microstructure of the phase layer. It was found that mechanism of the film formation in...

With using the carbon nano-tube (CNT) of high chemical activity, nano-TiCx particles with different growth shapes were synthesized through the self-propagating high temperature in the 80 wt.% metal (Cu, Al, and Fe)-Ti-CNT systems. The growth shapes of the TiCx particles are mainly octahedron in the Cu- and Al-Ti-CNT systems, while mainly cube- and sphere-like in the Fe-Ti-CNT system.

in this study the effects of fe2o3 and fe3o4 magnetic nanoparticles and edta on urease activity was investigated. the effect of nano-fe2o3 and nano-fe3o4 on urease activity were investigated. urease activity was studies by uv-vis spectrophotometry at 40 °c at ph = 7.2 using sodium phosphate as buffer. measurements were carried out using 0.075 mg/ml of urease and a range of nano-fe2o3 and nano-f...

this study was conducted to determine the spatial variability and mapping of available micronutrients iron, zinc, copper and manganese on 20,000 hectares of soils in south of tehran lands in order to identify deficiency, enough and toxicity areas. 196 surface soil samples (0-25cm) to a regular grid network of 1000×1000m were collected and extracted by dtpa and tea and concentrations of elements...

this work reports a facile sonochemical route in the synthesis of nano particle of deferasirox for the first time. one application of nanotechnology is in improvement of available treatments for various diseases. deferasirox (icl670 or exjade) is a tridentate chelating agent for removing transfusion overload iron in thalassemia patients. in the present work, deferasirox was prepared in nano size...

Magnetic sulfide-modified nanoscale zerovalent iron (S-nZVI) is of great technical and scientific interest because of its promising application in groundwater remediation, although its synthesis is still a challenge. We develop a new nanoparticle seeding method to obtain a novel and reactive nanohybrid, which contains an Fe(0) core covered by a highly sulfidized layer under high extent of sulfi...

Various compounds have been used for microencapsulating of fish oilso far, but in thiswork for the first time, inulin and casein which are both known for their functional properties, were used as the coating materialof fish oil.This study aimed to investigate the properties of nano-emulsions (droplet size measurements and pH) based on changes in the concentration and type of wall and their effe...

In the framework of pollutant sequestration by magnetic nano materials, this work focuses on synthesis and physico-chemical properties starch functionalized magnetites. Nanoparticles were prepared Fe2+/Fe3+ coprecipitation method with increasing amount in medium (starch to iron mass ratio (R) range 0–10). Obtained materials characterized Transmission Electron Microscopy (TEM), Powder X-Ray Diff...
