In this study, nanocomposite coatings based on polyurethane cerium nitrate montmorillonite (MMT) were prepared, applied on carbon steel substrates, and investigated. The nanocomposite coatings were successfully prepared by the effective dispersing of nanoparticles in polyurethane resin by mechanical and sonication processes. The state of dispersion, dissolution, and incorporation were character...

In this paper, graphene oxide decorated with cerium oxide (CeO2) nanoparticles was prepared and used as anticorrosive pigments in epoxy nanocomposite coatings. The synthesized nanoparticle was characterized by FTIR, XRD, SEM, and EDX analyses. Graphene oxide decorated with CeO2 nanoparticles was dispersed in epoxy resin by sonication. The optimum nanoparticle content of th...

In the present study, Ni-P-CNT composite coating was successfully fabricated via electroless plating. Scanning electron microscopy (SEM) was used to characterize the coatings. The effect of CNTs concentration in the bath on its content in the composite coatings was studied. Furthermore, the corrosion behaviour of the coatings with different contents of CNTs was evaluated using Tafel polarizatio...

In this study a series of epoxy/silica nanocomposites were prepared by using nano silica particles which had different surface modifications. The morphology of the nanocomposite coatings was characterized by scanning electron microscopy SEM. The effects of the hydrophilic and hydrophobic feature of the nano particles on the Tg and anticorrosive properties of nanocomposite coatings were evaluate...

The presence of gas is a common feature in many seismic sections. However, the origin of the gas is often difficult to determine. Recently acquired very high resolution seismic profiles using an IKB Seistec boomer provide useful insight to the understanding of the gas origins in a range of environmental settings including sea lochs and coastal lagoons. The gas features are described both from a...

Nanoindentation techniques are widely used for the study of nanomechanical properties of thin nanocomposite coatings. Theoretical concepts and practical use of nanoindentation method are summarized with reporting the applications of these tests in characterization of some particular thin nanocomposite hybrid coatings prepared by sol-gel process. The better mechanical properties can be obtained ...

in this research, the effect of active edible coating based on carbocymethyl cellulose (cmc) containing pomegranate peel extract (ppe) and rese essential oil (reo) and also vacuum packaging (vp) on chemical attributes and microbial quality of packaged pomegranate arils during 15 days storage at 5 °c have been studied. the weight loss was increased by increasing storage time. but all treatments ...
