the present article reports on the application of modified organo nanoclay as a green, easily prepared and stable solid sorbent for the preconcentration of trace cobalt ion in aqueous solution. the organo nanoclay was modified by adsorption of 5-(4-dimethyl amino-benzylidene) rhodanin reagent onto it. the sorption of co2+ ions was quantitative in the ph range of 7.0 to 8.5, whereas quantitative...

Wind erosion and dust storms are main issues in arid and semi-arid regions. Application of soil stabilizer on unstable land might be an eff ective and sustainable strategy in arid and semi-arid countries to minimized harmful eff ects on environment and human health. Th e aim of this study was to assess the eff ect of using nanoclay for increasing soil stability, as a result of increasing in siz...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Composite materials are widely used because of their extreme properties. Researchers working on fabrication of new composite materials worldwide to enhance the applicability of these materials. There are very few works about the effect of nanoclay ...

Composite materials play a vital role in many industrial applications. Researchers are working on fabrication of new composite materials worldwide to enhance the applicability of these materials. In view of this, the objective of the present work is to analyze the effect of nanoclay content on the mechanical and morphological behavior of S-glass fiber, reinforced in Polyester with nanoclay as f...

Musculoskeletal tissue engineering aims at repairing and regenerating damaged tissues using biological tissue substitutes. One approach to achieve this aim is to develop osteoconductive scaffolds that facilitate the formation of functional bone tissue. We have fabricated nanoclay-enriched electrospun poly(ɛ-caprolactone) (PCL) scaffolds for osteogenic differentiation of human mesenchymal stem c...

Membranes with more resilience to abrasive wear are highly desired in water treatment, especially for seawater desalination. Nanocomposite poly(vinylidene fluoride) (PVDF)/nanoclay membranes were prepared by phase inversion and then tested for abrasion resistance. Their material properties were characterized using Fourier-transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA),...

Preparation of E-glass/waterborne epoxy prepregs containing natural nanoclay and properties of their composites are presented. Prepregs were prepared by wetting randomly oriented, chopped glass fiber preforms with aqueous dispersion of EpiRez 3522-W-60 resin, dicyandiamide, 2-methylimidazole and natural nanoclay (Cloisite Naþ). The nanoclay content of the aqueous dispersion was adjusted to yiel...

A novel approach for characterisation of nanoclay dispersion in polymeric composites using electron microprobe analysis (EMPA) is presented. Dispersion analysis was performed on three sets of centre-gated discs fabricated by resin transfer moulding. The first set was neat epoxy polymer without reinforcement, whereas the second set comprised 17 vol.-% randomly oriented chopped glass fibre prefor...

Thermoplastic elastomers are a special class of polymeric materials that combine the properties of thermo plasticity during processing and rubber-like behaviour in service. They can be processed in conventional plastic processing equipment, such as twin screw extruders, internal batch mixers, extruders and injection moulding machine, but exhibit vulcanized rubber like ultimate properties (i.e. ...

Chitosan-nanoclay bio-hybrid films were successfully crosslinked with glutaraldehyde, genipin and glyoxal. Moisture sensitivity of films decreased as a result of crosslinking which led to improved barrier properties against water vapor and oxygen. Films containing chitosan (6.6 g/m) with genipin (3.3 g/m) and nanoclay (6.6 g/m) had water vapor transmission rate of 72 g × 100 μm/(m × 24 h) which...
