This article provides an up-to-date review on nanocomposites composed of inorganic nanoparticles and the polymer matrix for optical magnetic applications. Optical or characteristics can change upon decrease particle sizes to very small dimensions, which are, in general, major interest area nanocomposite materials. The use into provide high-performance novel materials that find applications many industrial fields. With this respect, frequently considered features are properties such as light...

Abstract The high concentration of grain boundaries provided by nanostructuring is expected to lower the thermal conductivity thermoelectric materials, which favors an increase in their figure‐of‐merit, ZT . A novel chemical alloying method has been used for synthesis nanoengineered‐skutterudite CoSb 3 powders were annealed different durations obtain a set samples with particle sizes. then compacted into pellets uniaxial pressing under various conditions and characterization. transport...

Immobilization of bovine serum albumin (BSA) on surface-modified superparamagnetic iron oxide nanoparticles (SPION) has been performed by two different double-step immobilization approaches. The first approach consists preparation SPION controlled chemical coprecipitation in the presence BSA solution, whereas second includes preliminary surface modification with an amine group using a coupling agent 3-aminepropyltrimethoxysilane (APTMS). Both procedures are followed...

The cuticle of mussel byssal threads is a robust natural coating that combines high extensibility with stiffness and hardness. In this study, fluorescence microscopy elemental analysis were exploited to show the 3,4-dihydroxyphenyl-l-alanine (dopa) residues foot protein-1 colocalize Fe Ca distributions in Mytilus galloprovincialis threads. Chelated removal from intact resulted 50% reduction hardness, thin sections subjected same treatment showed disruption integrity. Dopa-metal complexes may...

Abstract Eosinophil peroxidase (EPO) is one of the major oxidant‐producing enzymes during inflammatory states in human lung. The degradation single‐walled carbon nanotubes (SWCNTs) upon incubation with EPO and H 2 O reported. Biodegradation SWCNTs higher presence NaBr, but neither alone nor caused nanotubes. Molecular modeling reveals two binding sites for on EPO, located at proximal side (same as catalytic site) other distal EPO. oxidized groups both cases are stabilized by electrostatic...

Bismuth telluride (Bi2Te3) is the best-known commercially used thermoelectric material in bulk form for cooling and power generation applications at ambient temperature. However, its dimensionless figure-of-merit-ZT around 1 limits large-scale industrial applications. Recent studies indicate that nanostructuring can enhance ZT while keeping of by employing an advanced synthetic process accompanied with novel consolidation techniques. Here, we report on nanostructured (NS) undoped Bi2Te3...

ABSTRACT Monodisperse mesoporous silica (mSiO 2 ) coated superparamagnetic iron oxide (Fe 3 O 4 @mSiO nanoparticles (NPs) have been developed as a potential magnetic resonance imaging (MRI) T contrast agent. To evaluate the effect of surface coating on MRI efficiency, we examined proton relaxivities Fe NPs with different thicknesses. It was found that mSiO has significant impact efficiency for enhancement. The increases thickness and is much higher than commercial agents. Nuclear (NMR)...
