In this study, spherical Nb2O5 nanoparticles were synthesized by a novel chemical method as a simple, robust, surfactant-free, non-toxic and widely applicable approach. In order to investigate the effect of initial concentration on particle sizes, nanoparticles with different initial concentration were synthesized. Ultrasonic assisted method was applied and the effects of ultrasonic treat...

the perovskite-structured la2cuo4 nanoparticles (lco nps) have been synthesized via an ultrasonic-assisted co-precipitation route using octanoic acidas organic surfactant, and the phase composition, morphology, lattice parameters and size of nanoparticles  are characterized through fourier transform infrared spectroscopy (ft-ir), x-ray diffraction (xrd), scanning electron microscopy (sem) and t...

The functional silica/polyamide-imide composite films were prepared via simple ultrasonic blending, after the silica nanoparticles were modified by cationic surfactant-cetyltrimethyl ammonium bromide (CTAB). The composite films were characterized by scanning electron microscope (SEM), thermo gravimetric analysis (TGA) and thermomechanical analysis (TMA). CTAB-modified silica nanoparticles were ...

this research reports a facile ultrasonic approach for the synthesis of iron vanadate (fevo4) nanoparticles with the aid of ammonium metavanadate (nh4vo3) and fe(no3)3.9h2o as the starting reagents without adding external surfactant, capping agent or template in an aqueous solution. furthermore, to examine the solar cell application of as-synthesized iron vanadate (fevo4) nanoparticles, fto/tio...

the perovskite-structured la2cuo4 nanoparticles have been synthesized via an ultrasonic-assisted co-precipitation route using octanoic acid as organic surfactant, and the phase composition, morphology, lattice parameters and size of nanoparticles are characterized through fourier transform infrared spectroscopy, x-ray diffraction, scanning electron microscopy and transmission electron microscop...

We have found that not only block copolymers but also ionomers can self-assemble in a selective solvent to form surfactant-free nanoparticles. The self-assembly can be induced by chemical reaction, polymer-polymer complexation, and microphase inversion in addition to the temperature. A recently developed microwave method for the preparation of uniform surfactant-free polymeric nanoparticles is ...

Targeted drug delivery to endothelial cells lining the vasculature can improve treatment of many pathologies. Intercellular adhesion molecule-1 (ICAM-1), a transmembrane glycoprotein overexpressed in many diseases, is a good determinant for endothelial targeting of drug nanoparticles (NPs). In this study we synthesized surfactant-free, FITC-labeled poly(lactic-co-glycolic) acid (PLGA) NPs coate...
