Nano ZnO/ montmorillonite composite were prepared by sol gel method under ultrasonic irradiation from directly mixing montmorillonite nano clay into Zinc gel. The Zn(CH3COO)2.2H2O and montmorillonite nano clay was used as precursor. The zinc acetate was dissolved in DI water and, NH3 (aq) solution was dropped into the zinc solution until pH 9 consequently the zinc gel was produced. The montmori...

Nano-materials have been widely accepted for many purposes as improvement materials several engineering projects. In this research, an attempt was made to study the effect of using two types Nano-materials, namely: Nano-SiO2 and Nano-clay, investigate mechanical properties soil improved with aid permeation grouting technique. Three different ratios Nano-materials/ water (1/30, 1/50, 1/100) were...

a suitable option for manufacture of packing materials is the use of clay and silver nano particles. these materials help create optimal relative impermeable quality, in addition to other features being improved. moisture-packed bread by use of these materials prevent water vapor loss and therefore reduce the level of bread becoming stale. in this study, seven types of nano-films with different...

The sequestration of carbon and nitrogen by clay-sized particles in soils is well established, and clay content or mineral surface area has been used to estimate the sequestration potential of soils. Here, via incubation of a sieved (<2 mm) topsoil with labelled litter, we find that only some of the clay-sized surfaces bind organic matter (OM). Surprisingly, <19% of the visible mineral areas sh...

Until recently, discoloration of the denim garment has been carried out through various methods including mechanical, chemical, physical and enzymatic treatments. In this study, the nano clay was co-applied in bio stone washing of denim with cellulase to obtain denim garment with a new look and clear effluent. Acid and neutral cellulases along with nano clay were applied on the dyed denim fabri...

Nowadays, titanium-based alloys are among the most attractive metallic materials for biomedical applications (as implants) due to their non-biodegradability, low density, good mechanical properties as well as their good biocompatibility. Hydroxyapatite (Ca10 (PO4)6(OH)2, HA) has been widely used for biomedical applications due to its bioactive, biocompatible and osteoconductive properties. Firs...

in the current study, whey protein- pullulan- clay nanocomposite films are prepared by casting method. the effect of nanoclay at three concentrations (1%, 3% and 5%) on physical properties such as moisture content, solubility in water, water vapor permeability and transparency of whey protein- pullulan composite films investigated. the results show that the effect of nanoparticles on composite ...

In this research, commercial nano-clay (NC) was modified with TiO2 functional groups and characterized via XRD and FTIR methods. The modified nano-clay was applied as an adsorbent for the removal of cadmium from wastewater solutions. The effects of the operating parameters including initial pH, cadmium concentration and adsorbent concentration were analyzed by the Taguchi method. The...

Polymeric composite films with a high loading of nano-size silicates can hardly meet the increasingly stringent fireproof and smoke-free requirements during burning. Thus, it is desirable to prepare pure clay films that can block air, heat, and flame. Here we report an organic-free clay film capable of both flame- and heat-shielding. The film was prepared from the self-assembly of nanometer-thi...

BACKGROUND Nowadays significant attention is to nanocomposite compounds in water cleaning. In this article the synthesis and characterization of conductive polyaniline/clay (PANI/clay) as a hybrid nanocomposite with extended chain conformation and its application for water purification are presented. METHODS Clay samples were obtained from the central plain of Abhar region, Abhar, Zanjan Prov...
