Abstract The Nickel oxide nanoparticles (NiO NPs) and oxide/Nanoclay nanocomposite (NiO/Nc NC) were synthesized by chemical reduction method used for the photodegradation of Orange II dyes in aqueous solution. samples characterized through SEM, EDX, FTIR TGA. SEM analysis presented that NiO NPs are spherical with irregular shapes sizes. size particles is range 100–400 nm. It was also observed d...

Abstract Three-dimensional (3D) extrusion printing of cellular/acellular structures with biocompatible materials has been widely investigated in recent years. However, the requirement a suitable solidification rate printable ink constrains utilization extrusion-based 3D techniques. In this study, nanoclay yield-stress suspension-enabled system and demonstrated to overcome constraints during pri...

Since the last decade, research activities in the area of nano-materials have been increased dramatically. More than a 1000 of journal articles in this area have been published within the last 3 years. Materials scientists and researchers have realized that the mechanical properties of materials can be altered at the fundamental level, i.e. the atomic-scale. Carbon nanotubes (hereafter called ‘...

This study was conducted in response to one of the research needs of National Institute for Occupational Safety and Health (NIOSH), i.e. the application of nanomaterials and nanotechnology in the field of occupational safety and health. In order to fill this important knowledge gap, the equilibrium solubility and diffusion of carbon tetrachloride and ethyl acetate through carboxylated nitrile b...

The present work was aimed to examine the effects of incorporation of each of two different types of nanoclay, i.e. Cloisite Na+ and Cloisite 30B, into PVA foam on cellular morphology and water absorption capacity. Foam samples containing 0.0-10.0 wt% of each of the two types of nanoclay alone were prepared using mechanical foaming. Accordingly, PVA/organoclay/water suspensions were prepare...

Organo-Montmorillonite (o-MMT) nanoclay added polybenzoxazine resin (type I composites) were prepared with varying amounts of clay (0, 1, 2, 4 and 6 wt %). Clay dispersion, changes in curing behaviour thermal stability assessed type composites. Findings from these studies composites used to understand stability, mechanical, mass ablation rate carbon fiber reinforced II). Interlaminar shear stre...

Polypropylenes loaded with different alkyl ammonium-modified montmorillonite are prepared to utilize a melt-mixing technique in various ways. Two types of polypropylene and compatibilizer are incorporated to improve the dispersion of various types of nanoclay and the dyeing behavior of the nanocomposites with various disperses, so acid and basic dyes were studied. For the first time, the aim of...

In this study, several examples of hydrogels and nanocomposite hydrogels based on PVP with different content of montmorillonite nanoclay were prepared. Then, the swelling of hydrogels and kinetics of drug delivery of hydrogel in an environment similar to the body (pH 7.4) were examined. The effect of nanoparticle different percentages on the hydrogel was clearly observed. Then kinetics of drug ...

nanocomposite samples based on elastomer blends of butyl rubber (iir) and ethylene propylene diene monomer (epdm) were prepared using a laboratory scale two-roll mill in order to study the effect of cloisite 15a organoclay content (i.e., 1, 3, 5 and 7 wt%) on the mechanical and morphological properties  of  iir/epdm/cloisite  15a  nanocomposites  compared  to  the  unflled epdm/iir blends. rheo...
