Electroless deposition of Au onto Si(111) studied by surface second harmonic generation
Electroless deposition of Au onto hydrogen-terminated Si(111) from aqueous HF solutions has been studied by Rutherford backscattering (RBS) and in situ surface second harmonic (SH) generation. The SH signal as a function of time goes through a maximum which becomes stronger and occurs at shorter times as the HF concentration is increased. This can be explained through resonant enhancement of th...
متن کاملPreparation of nano gold powder from acid leaching tail solution
According to the unique properties and many applications of nano gold powder, it was prepared from an acid leaching tail solution. The low value residual gold ions existed in acid leaching tail solution in Mouteh gold mine in Iran with fellow heavy metals as pollutants (Fe2+, Cu2+, and Zn2+). Preparation of nano gold particles is achieved by two steps: First, by addition of ammonia as separatio...

متن کاملAdsorption of Basic Blue 41 from Aqueous Solution onto Coconut Fiber Particles
In this research, adsorption experiments were carried out for removal of Basic Blue 41(BB41) dye from an aqueous solution, using coconut fiber particles (CFP) as a low-cost biosorbent. The characteristics of coconut fiber particles weredeterminedwith a scanning electron microscope (FE-SEM) and Fourier Transform Infrared (FTIR) techniques. The effects of initial pH, biosorbentdose, contact time,...
متن کاملSpectroscopic study of ionic liquid adsorption from solution onto gold.
Gold was exposed to ethanol solutions containing 0.1 wt% 1-hexyl-3-methyl-imidazolium bis(trifluoromethanesulfonyl)imide (HMIM NTf2), an ionic liquid (IL). The resulting adsorbed layers were interrogated using X-ray photoelectron spectroscopy (XPS - both conventional and synchrotron-based) and spectroscopic ellipsometry. Ellipsometry indicated that the adsorbed layer thickness was smaller than ...
