In this article, we have developed a simple model that describes the adsorption of polymer chains from a solution having a good solvent onto a reactive surface of varying curvatures. In order to evaluate the impact of particle size on the adsorption process, we have probed the adsorption of poly(methyl methacrylate) (PMMA) on aluminum oxide (Al2O3) surfaces(More)
The present paper presents a facile and low-cost hydrothermal method to synthesize stoichiometric FeNi3 alloy nanoparticles by reducing Ni(NO3)2.6H(2)O and Fe(NO3)2.9H(2)O with hydrazine hydrate in strong alkaline media. X-ray diffraction patterns of as-prepared samples synthesized at 180 degrees C for different hydrothermal reaction times reveal that the(More)
The local conformation of RNA molecules is an important factor in determining their catalytic and binding properties. The analysis of such conformations is particularly difficult due to the large number of degrees of freedom, such as the measured torsion angles per residue and the interatomic distances among interacting residues. In this work, we use a(More)
The flow behavior of nanostructure clusters, consisting of chemically bonded PbSe quantum dots and magnetic gamma-Fe(2)O(3) nanoparticles, has been investigated. The clusters are regarded as model nanoplatforms with multiple functionalities, where the gamma-Fe(2)O(3) magnets serve as transport vehicles, manipulated by an external magnetic field gradient,(More)
We have studied the flow behavior of chemically-conjugated nanostructures consisting of fluorescent PbSe quantum dots coupled with magnetic γ-Fe 2 O 3 nanoparticles, under viscous flow and an external magnetic field. The γ-Fe 2 O 3 moieties were used to control the trajectories of the nanoplatforms under an external magnetic field in polymers fluids(More)
