Wind erosion is a widespread phenomenon in arid region. The purpose of this study was assessed the capacity of nanoclay to control soil erosion in wind tunnel experiment. The nanoclay isolated from soils was dominant in montmorillonite. A sandy soil from the Khara desert, nearly 100 km East of Isfahan (Central Iran) was used. The soils of this area are structurally unstable and sandy texture ma...

The potential use of nanoclay was examined to modify fluid transfer properties of medium density fiberboard (MDF). For this, Na+ montmorillonite (Na+MMT) nanoclay was added to urea formaldehyde resin to produce MDF. Then, the air permeability and mass diffusivity of MDF were evaluated. Scanning electron microscope (SEM) images and X-ray diffraction (XRD) confirmed a dispersion and exfoliation o...

The effect of nanoclay content on the properties of glass fibre reinforced, waterborne epoxy laminates is investigated. Fourteen ply nanocomposite laminates containing 0, 0?1, 0?2, 0?5, 1 and 2 wt-% cloisite Na nanoclay are fabricated by a hot press. The interlaminar shear strength, flexural strength and flexural stiffness of the fabricated nanocomposites are characterised. In addition, the the...

Nanoclays are layered mineral silicates, i.e., silicate nanosheets. such as montmorillonite, bentonite, kaolinite, etc., have been used reinforcements in the nanofibers. Numerous polymers to fabricate nanofibers, including poly(vinylidene fluoride), poly(vinyl alcohol), polycaprolactone, nylon, polyurethane, poly(ethylene oxide), and others. To develop better compatibility with polymers, nanocl...

The objective of this study is to review existing literature in the area of nano-modification of asphalt and proceed to apply nano-materials to asphalt to improve the performance. This study integrates literature review, preparation, and characterization of nano-modified asphalt materials. In the experimental testing montmorillonite, nanoclay at 2% and 4% by weight of asphalt was blended in asp...

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...

OBJECTIVE The objective of the present study is to investigate the reinforcement effect of polymer-grade montmorillonite (PGN nanoclay) on physical properties of glass ionomer cement (GIC). MATERIALS AND METHODS The PGN nanoclay was dispersed in the liquid portion of GIC (HiFi, Advanced Healthcare, Kent, UK) at 1%, 2% and 4% (w/w). Fourier-transform infrared (FTIR) spectroscopy was used to qu...

Nanomaterials are relatively new and unconventional materials with many useful properties, but their effects on biological systems are poorly understood. Nanoclay is a general term for layered mineral silicate nanoparticles that are ideally suited for use in clay-based nanocomposites. The potential biological hazards of nanoclays have not been addressed, however. Therefore, we investigated the ...

The effect of nanoclay concentration on the molecular orientation and drawability of poly(ethylene terephthalate) PET was examined using thermal and vibrational spectroscopic analysis. Although drawability at 83 C in hot air increased by the addition of nanoclay, the maximum draw ratio was independent of nanoclay concentration. The average molecular orientation of the PET chain was found to mim...
