Oxygen reduction has been studied on glassy carbon rotating disc substrates modified by platinum- and gold-coated copper particles. The deposits have been formed by a two-step process, whereby controlled amounts of Cu were electrodeposited onto the substrate and were subsequently coated with a thin...
On carbon coated copper grids of 5 mm diameter, drops of Au/Ag-CQD-NC and Ag-CQD-NC were placed with care and additional solution was soaked up carefully with absorbent paper. Samples were stained with 1% phosphotungstate solution and the hybrid nanocomposites were viewed at 10000X ...
The core size and shape of AuNP were examined with transmission electron microscopy (TEM) using a JEOL 1010 microscope (JEOL USA Inc., Peabody, MA) at 80 kV. 10 μL of diluted AuNP solution was dropped onto carbon-coated copper grids (FCF-200-Cu, Electron Microscopy Sciences, Hatfie...
Colloids are particles with at least one direction with dimensions comprised between 1 nm and 1 μm. Although silver nanoparticles are responsible for the greenish tone, the translucent reddish is attributed to the gold nanoparticles. These nanoparticles, along with the other traces of copper, an...
The morphology and size distribution of the papaya leaf extract capped AuNPs was investigated by transmission electron microscopy, by casting the nanoparticle dispersion on carbon-coated copper grids and allowed to dry at room temperature. Measurements were made on TECHNAI G2 F30 S-TWIN instrument. ...

In addi- tion to monolayers on carbon-coated copper grids, scattering data was also collected for aqueous Au NP colloid using the method documented elsewhere28. Finite-difference time domain (FDTD) simulation. Three dimensional (3D) FDTD simulations were performed with commercially available ...
Samples were centrifuged and dispersed in water previous to their deposition (10 μL) on an ultrathin formvar-coated 200-mesh copper grid (Ted-pella, Inc.). Average size and size distribution of the samples were measured using ImageJ software by counting at least 500 particles....
