This manuscript describes a rheological and tribological study carried out on eco-friendly lubricants. These ecolubricants were made up of nanoclays as dispersed phase (a layered nanosilicate (montmorillonite Cloisite 15A) fiber-like nanoclay (sepiolite Pangel B20)) vegetable-based oil continuous (castor (CO), high oleic sunflower (HOSO) their mixtures). A series nanoclay-based prepared by vary...

Abstract Liquid metal is an ideal conductive material for soft electronics because of its high conductivity and fluidity at room temperature. However, the large surface tension mass density liquid make forming three-dimensional (3D) dangling structures a challenging task. Reported here suspension printing strategy direct deposition galinstan-based into 3D with shape fidelity spatial resolution ...

Using low permeability soils in landfill liners is a guaranteed leachate control and prevents leakage which causes environmental pollution. In this matter, the application of new technologies such as nano provides more capable filters that are used for reducing pollutants modifying geotechnical properties liners. The presented study attempted to conduct experimental research on nanoclay–nanofib...

Polymer-nanoclay composite materials have attracted considerable interest among materials scientists recently because of the pioneering work carried out by a research group in the Toyota Central Research Laboratories. The group applied a nylon-montmorillonite clay nanocomposite as an under-the-hood structural part in the engine compartment of an automobile with significantly improved tensile st...

In current work, halogenated sunflower oil was reacted with Na2S3 to produce sunflower oil-based polysulfide polymer. Cloisite 30B as organomodified nanoclay was used in different contents to investigate its effect on the properties of the synthesized polymer. All nanocomposites were prepared via in situ polymerization method in aqueous media. Fourier Transform-InfraRe...

the organo-metal salt of aluminum triacrylate (alta) with a general formula of (ch2=chcoo)3al was  synthesized  as  a  reactive  fller  for  elastomers through a two-step synthetic procedure. fourier transform-infrared spectroscopy (ftir), dsc and dta were employed for alta analysis and to study its cure characteristics. in this research, two composites based on ethylene propylene diene monomer...

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...

In this work, the influence of composition and cold-drawing on nanoand micro-scale morphology and tensile mechanical properties of PE/organoclay nanocomposite fibers was investigated. Nanocomposites were prepared by melt compounding in a twin-screw extruder, using a maleic anhydride grafted linear low density polyethylene (LLDPE–g–MA) and an organomodified montmorillonite (Dellite 67G) at three...

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 ...
