This study focuses on the deposition and growth mode of rhodium (Rh) on gold (Au) seed nanorods (NRs). Using a combination of scanning transmission electron microscopy imaging, energy-dispersive X-ray spectroscopy, and UV-visible absorption spectroscopy, we show that Rh deposition results in an uneven overlayer morphology on the Au NR seeds, with a tendency for Rh deposition to occur preferenti...

Reaction of poly(y-ethyl L-glutamate) with N-(3-aminopmpy1)imidazole gives an imidazole doped polymer which f o ~ m s 6-coordinate complexes with iron(II1) porphyrins. Modified electrodes are prepared using these porphyrin containing polymers. The new matelids are characterised by cyclic voltammetry, UV-visible spectroscopy and by sui-face enhanced resonance Raman spectroscopy. The techniques a...

A new complex of Chromium(III) and the cross-bridged macrocyclic ligand 4,11-dimethyl-1,4,8,11tetraazabicyclo[6.6.2] hexadecane has been synthesized. Complexation of Tungsten, Vanadium, and Molybdenum was unsuccessful. The Cr(III)(L) complex was characterized using UV-Visible spectroscopy λmax = 583nm , IR Spectroscopy, X-Ray Crystallography, and magnetic susceptibility ueff = 3.95. These tests...

A general synthetic method capable of producing a kind of water-soluble gold nanoparticles possessing single-phase synthetic route, high concentration, small size under control, easy store, and excellent thermal, pH and salt stability, was demonstrated. The combined studies with transmission electron microscopy (TEM), Energy dispersive X-ray spectroscopy (EDS), X-ray photoelectron spectroscopy ...

in this research zinc oxide (zno) nano-crystalline powders were prepared by sol-gel method using zinc acetate. the zno nanoparticles were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem), ultraviolet-visible (uv-vis), fourier transform infra-red (ft-ir) and energy dispersive x-ray (edx) spectroscopy. the structure of nanoparticles was studied using xrd pattern. the c...

Nanocrystalline Zinc Oxide (ZnO) powders with different morphology have been successfully synthesized by using different surfactants such as Cetyl Trimethyl Ammonium Bromide (CTAB), Sodium Dodecyl Sulphate (SDS), and Tri Ethanol Amine (TEA) via hydrothermal method. The products were characterized by means of powder X-ray diffraction (XRD), Scanning electron microscopy (SEM), Transmission electr...

In this work, ZnO/SiO2 nanoparticles were prepared using sol-gel method, and platinum particles were loaded on ZnO/SiO2 nanoparticles by photoreductive method. Samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FT-IR). The XRD patterns showed that the zinc oxide samples have a wurtzite structure (hexagonal phase...
