The formation of complexes between nanoparticles and polyelectrolytes is a key process for the control of the reactivity of manufactured nanoparticles and rational design of core shell nanostructures. In this work, we investigate the influence of the nanoparticle dielectric constant on the adsorption of a linear charged polymer (polyelectrolyte) at the surface of a neutral nanoparticle. The pol...

The Front Cover shows a gold nanoparticle decorated with simple xyloside ligand having 1,2,3-triazole backbone functionalized pyridine ring. prepared nanoparticles are highly stable in air for several days and soluble water. is covered an image of wheat field, illustrating the protective layer provided by monosaccharide units, which also prevents sedimentation nanoparticles. On right, reduction...

In many applications involving nanoparticles, the question of controlling properties films formed (particularly in terms porosity) remains incomplete. These cover an extensive array fields ranging from manufacture nanofilms to prediction pressure drop nanoparticle on surface air purification filters. A review literature shows that porosity nanometric particle deposits has mainly been studied by...

oxide nanoparticles can exhibit unique physical and chemical properties due to their limited size and a high density of corner or edge surface sites. in this study, mgo nanoparticle was synthesized using mg(ch3coo)2 and hexamethylenetetramine as starting materials. the structure and optical properties of these particles are investigated by using x-ray diffraction (xrd), scanning electron micros...

in this paper, the interaction between an oscillating dipole moment and a silver nanoparticle has been studied. our calculations are based on mie scattering theory and discrete dipole approximation(dda) method.at first, the resonance frequency due to excitingthe localized surface plasmons has been obtained using mie scattering theory and then by exciting a dipole moment in theclose proximity of...
