here, we report the synthesis of a schiff-base mixed-ligand complex of cadmium(іі) in bulk and nano-scales via the precipitation and sonochemical methods, respectively. the complex formula is [cd(3-bpdh)(3-bpdb)cl2]n (1), where the ligands are 3-bpdh = 2,5-bis(3-pyridyl)-3,4-diaza-2,4-hexadiene and 3-bpdb = 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene. the structure of mixed-ligand complex (1) wa...

We report an ionic hybrid based on silica nanoparticles as the anion and amine-terminated poly(ethylene oxide) (PEO) as a cation. The charge on the nanoparticle anion is carried by the surface hydroxyls. SAXS and TEM reveal an exceptional degree of dispersion of the silica in the polymer and high degree of order in both thin film and bulk forms. In addition to better dispersion, the ionic hybri...

The objective of this study was to improve the oxidation resistance of electroplated Ni-Cr coatings by introducing a fine dispersion of yttria (Y2O3) nanoparticles to the coatings. A technique was developed to produce Y2O3 nanoparticles nm in size. Electroplating conditions were also investigated and it was found that pulse plating could produce high quality coatings without cracking. The Y2O3 ...

The graphene oxide (GO) is successfully prepared from a purified natural graphite through a pressurized oxidation method. We experimentally demonstrate that GO as an optical media can be used for spatial light modulation based on plasma channels induced by femtosecond pulses. The modulated beam exhibits good propagation properties in free space. It is easy to realize the spatial modulation on t...

In this research, graphene oxide (GO) nanoparticles were modified by second and fourth generations of poly(amidoamine) dendrimers in order to improve the particle dispersion quality in the epoxy matrix and therefore its barrier anti-corrosion performance. Confirmation on the GO surface modification by Polyamidoamine generation 2 (PAMAM2) and polyamidoamin generation 4 (PAMAM4) was carried o...
