This article presents the method of extraction-preconcentration of Lead, Cadmium, and Nickel ions from food samples using the Ghezeljeh montmorillonite nanoclay (Geleh-Sar-Shoor) as a new native adsorbent in batch single component systems. The extraction-preconcentration of heavy metals were carried out by applying the solid phase extraction (SPE) method followed by atomic abs...

Polymer nanocomposites are new classes of composite materials derived from nanoparticles with at least one dimension in the nanometric range. Polypropylene nanocomposites have attracted a considerable interest due to its most widely used and fastest growing classes of thermoplastic polymer with low cost and low density. However, a problem associated with polypropylene is its dyeability. There h...

A versatile new concept is presented for the synthesis of Janus colloids composed of Laponite nanoclay armored poly(divinylbenzene) with an anisotropic surface potential via a double Pickering emulsion template. First, polystyrene or poly(divinylbenzene) colloids stabilized with Laponite nanoclay are synthesized via a Pickering miniemulsion approach. These nanoparticle-stabilized colloids were ...

A polycarbonate-based nanohybrid has been created containing 1 wt% of Bentone 2010, an organically modified montmorillonite. A micro-section on the nanohybrid obtained using focused ion beam (FIB) and field emission scanning electron microscopy (FESEM) was employed to observe the orientation of the nanoclay inside a polycarbonate (PC) matrix in the cross-section FIB-milled face. A micro-scratch...

Photopolymer composites filled with cellulose nanocrystal (CNC) and/or inorganic nanofillers were fabricated by using digital light processing (DLP) 3D printing. To investigate the effects of different CNC lyophilization concentrations and behaviors particles in photopolymer composites, morphological mechanical properties analyzed. loading levels affected composites. Better dispersion was seen ...

A novel fabrication of polymer composite fibers using polycaprolactone (PCL), montmorillonite nanoclay (MMT-Clay), and nano-hydroxyapatite-clay (HAP MMT-Clay) is reported for bone tissue engineering applications. Using a pressurized gyration (PG) setup, (PCL) incorporated with in situ mineralized HAP MMT-Clay were investigated. the method, we able to successfully manufacture HAP-nanoclay-PCL fi...

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...

Foam composite panels made from hybrid fillers are materials developed to have low density with high mechanical properties. This work focuses on improving the properties of epoxy-based foam hybridized by combining hollow glass microspheres (HGM) and nanoclay. The HGM content was varied 1 wt.% 3 in composites panel, while nanoclay 5 each HGM-filled series these were fabricated using a convention...
