in this study the performance of clay nano-particles on the soil reinforced with polypropylene fibers (pp-fiber) has been investigated. also a series of investigations concerning the effect of random orientation of fibers on the engineering behaviour of soil were conducted. soil mixtures were modified with varying percentages of nanoclay and fibers. unconfined compressive strength (ucs), compac...

Novel organic-inorganic hybrid materials comprising nanoscaled layered silicates and native aluminium hydroxide phthalocyanine (Al(OH)Pc) allowed for the first time the exploitation of their unique photophysical properties in aqueous ambience. In particular, we were able to observe the efficient emission of Al(OH)Pc-nanoclay hybrids and generation of singlet oxygen in aqueous solution.

Current work aims to study the mechanical and dynamical properties of non-woven bamboo (B)/woven kenaf (K)/epoxy (E) hybrid composites filled with nanoclay. The nanoclay-filled BK/E were prepared by dispersing 1 wt.% nanoclay (organically-modified montmorillonite (MMT; OMMT), (MMT), halloysite nanotube (HNT)) high shear speed homogenizer followed hand lay-up fabrication technique. effect adding...

BACKGROUND Substrates in medical science are hydrophilic polymers undergoing volume expansion when exposed to culture medium that influenced on cell attachment. Although crosslinking by chemical agents could reduce water uptake and promote mechanical properties, these networks would release crosslinking agents. In order to overcome this weakness, silicone rubber is used and reinforced by nanocl...

Nanoclay has proven to be an active anti-corrosive additive due the self-repairing effect from nanoclay swelling and expansion, except for its passive barrier high aspect ratio. But it is still uncertain how these effects of are intertwined with other components in a complex coating system corrosive environments. In this study, we examined combined nanoclays two particle sizes commonly used cos...

the performance of asphaltic pavements during their service life is highly dependent on the mechanical properties of the asphaltic layers. therefore, in order to extend their service life, scientists and engineers are constantly trying to improve the mechanical properties of the asphaltic mixtures. one common method of improving the performance of asphaltic mixtures is using different types of ...

This paper reports the dispersion of nanoclay in vinylester using co-rotating twin screw extrusion and ultrasonication for preparing nanoclay/vinylester gel coat. Two sets MMT/vinylester specimens, namely Type 1 2 were prepared comparative studies. While specimens only, both twin-screw extrusion. showed lower levels intercalation higher exfoliation. By coat so by two different routes, MMT/vinyl...

background:  ramsar, a northern city in iran, lies on the coast of the caspian sea. this city has areas with some of the highest levels of natural radiation measured to date. the radon concentration in some areas of ramsar is up to 3700 bq m–3. on the other hand, due to high level of humidity, damp-proof barriers should be used in construction of new buildings in radon prone areas of this city....

different amounts of nanoclay were incorporated into the acrylic resin matrix at 0, 1, 3, and 5 wt.% loadings. the coatings were applied on low carbon steel plates. optical microscopy, sedimentation test, transmission electron microscopy, and x-ray diffraction were employed to investigate the dispersion of nanoclay in matrix. the corrosion resistance of coatings was evaluated by electrochemical...
