Fluorescent organic nanoparticles based on aggregation induced emission dyes are fabricated through a ring-opening reaction using polylysine as the linker. The fluorescent organic nanoparticles obtained are characterized by a series of techniques including UV-vis absorption spectroscopy, fluorescence spectroscopy, Fourier Transform infrared spectroscopy, and transmission electron microscopy. A ...

SnO2 nanoparticles were dispersed on graphene nanosheets through a solvothermal approach using ethylene glycol as the solvent. The uniform distribution of SnO2 nanoparticles on graphene nanosheets has been confirmed by scanning electron microscopy and transmission electron microscopy. The particle size of SnO2 was determined to be around 5 nm. The as-synthesized SnO2/graphene nanocomposite exhi...

Green synthesis of silver and gold nanoparticles as two metal nanoparticles, was studied based on photoreduction of metal ions using molybdophosphoric acid (H3[PMo12O40], HPMo) under UV-irradiation. HPMo was found to be photocatalyst, reducing agent and efficient stabilizer for the resulting nanoparticles. This method allows the size-controlled synthesis of uniform nanoparticles with an average...

Abstract. This work investigates the deposition of Pt nanoparticles onto carbon aerogels (CA), derived from microcrystalline cellulose. Nanoparticles are synthesised via impregnating the CA with H2PtCl6 followed by reduction either under H2 at 300 C or in a basic NaBH4 solution. H2 reduction yields uniform Pt nanoparticles (average diameter < 2nm) dispersed over the CA surface as revealed by Tr...

The interactions of nanoparticles with polymer hosts have important implications for directing the macroscopic properties of composite fibers, yet little is known about such interactions with hierarchically ordered natural polymers due to the difficulty of achieving uniform dispersion of nanoparticles within semi-crystalline natural fiber. In this study we have homogeneously dispersed silver na...

DNA-containing micellar nanoparticles with distinctly different and highly uniform morphologies are prepared via condensation of plasmid DNA with a block copolymer of polyethylene glycol and a polycation in solvents of different polarity. Molecular dynamics simulations explain the underlying mechanism.

In this paper, polymer-based nanocomposites powder were applied on the surface of plain carbon steel by electrostatic device and then were cured by microwave. The effect of adding nanoparticles on the corrosion resistance properties of the coatings was investigated by Electrochemical Impedance Spectroscopy and immersion test in 3.5 NaCl solution. Coatings structure and morphology of nanoparticl...

We demonstrate the synthesis of 2D metal nanoparticles (MNPs)/graphene nanocomposites using small cationic surfactants as stabilizers. 2D sandwich-like MNPs/graphene nanocomposites with a uniform distribution of MNPs can be achieved via a one-pot in situ growth and reduction protocol.

In the present work, the synthesis of Barium hexaferrite (BaFe12O19) nanoparticles in thepresence of a large excess amount of OH− anions by the hydrothermal method in the presence and absence of surfactants such as Sodium dodecyl benzene sulfonate and Triton X-114 was reported. The optimized temperature in the absence of surfactant was determined (200 °C) and then Barium hexaferrite nanoparticl...
