The resonance Raman spectrum of a polycrystalline sample of AgMnO4 allowed a wider insight into the vibrational properties of the MnO 4 ion in this lattice. This study confirmed important covalent contributions to the overall structure and strong cooperative effects between the ions present in the ...
Surface Raman electromagnetic enhancement factors for molecules at the surface of small isolated metal spheres: The determination of adsorbate orientation ... Two new broad and strong Raman bands in the surface-enhanced Raman spectrum of pyridine adsorbed on colloidal silver particles were observed, one...
When cadmium oxide nanopar- ticles were added to stem cells germ lines at the Scanning electron microscopy of stem cell aggregates The morphology and shape of the stem cells, after treat- ment with different concentrations of biosynthesized AgNPs were analyzed by scanning electron microscopy (SEM)...
FTIR spectrum of (a) pureLiNbO3, Ag-decorated LiNbO3at (b) 5 s, (c) 15 s, (d) 25 s, (e) 35 s and (f) 45 s. Full size image Raman spectra measured Figure9illustrates the Raman spectra with the wave numbers ranging from 200 to 1000. The peaks for pure LiNbO3were observed a...
The detection limit for the silver-doped sol−gel film was 104 times lower than that for the silver-coated silica beads. The sol−gel substrate was further used to obtain, for the first time, the surface-enhanced Raman spectrum of neptunyl ions in dilute aqueous solutions. 展开 ...

Nanoparticles (NP) are synthesized from fauna/flora extracts and elements such as silver (Ag), gold (Au), platinum (Pt), nickel (Ni), zinc (Zn), copper (Cu), and compounds like titanium dioxide (TiO2), ferrous oxide (FeO), and ferric oxide (Fe2O3)1. The applications are primarily...
For comparison, a reduced graphene oxide silver nanowire (RG-AgNW) hybrid is also prepared by the similar procedure but without adding boron oxide. Figure 1 illustrates the procedure scheme for synthesizing silver nanowire decorated boron doped graphene sheets. The experimental procedure is detailed ...
Ag-catalysed ethene epoxidation is the only viable route for making ethene oxide (EO) in industry, but the active site remains elusive due to the lack of tools to probe this reaction under high temperature and high-pressure conditions. Here, aided by advanced machine-learning grand canonical glo...
