Gold ion implantation into alumina using an “inverted ion source” configuration.
(AIP PublishingAIP Publishing LLCNova York, 2014-02-21)
We describe an approach to ion implantation in which the plasma and its electronics are held at
ground potential and the ion beam is injected into a space held at high negative potential, allowing
considerable savings ...
Ion pair method to determine the CTAB content in gold nanorods samples
(Sociedad Chilena de Quimica, 2015)
In this work, we report a fast and accessible method for quantification of cetyltrimethylammonium bromide (CTAB) in solutions of gold nanorods (GNRs) by bromophenol blue (BPB) ion-paring formation and spectrophotometric ...
Gold Nucleation Inhibition by Halide Ions: a Basis for a Seed-Mediated Approach
(Royal Society of Chemistry, 2015-01)
In the present work, we examine the effect of halide ions on gold nucleation, a typical synthetic variable in the wet-chemical production of gold nanostructures. It was found that the homogeneous nucleation of gold by the ...

Incorporation of gold nanoparticles into Langmuir-Blodgett films of polyaniline and montmorillonite for enhanced detection of metallic ions
(2016-11-29)
We report on effects from incorporating gold nanoparticles (AuNPs) into Langmuir-Blodgett (LB) films of emeraldine salt polyaniline (PAni-ES) and organophilic montmorillonite clay (OMt). The synergistic electrocatalytic ...
On the Energetics of Ions in Carbon and Gold Nanotubes
(Wiley VCH Verlag, 2016-01)
We investigate the insertion of halide and alkali atoms into narrow single-walled carbon nanotubes with diameters <9 Å by density functional theory; both chiral and non-chiral tubes are considered. The atoms are stored in ...
A novel environmentally friendly method in solid phase for in situ synthesis of chitosan-gold bionanocomposites with catalytic applications
(Elsevier Ltd, 2019)
A novel method to obtain catalytic bio-nanocomposites based on chitosan containing different amounts of gold nanoparticles generated in situ is reported. The formation of gold nanoparticles takes place in solid phase ...
Bonding in gold-rare earth [au 2 m] (m = eu, yb, lu) ions. A strong covalent gold-lanthanide bond
(2017)
The electronic structure and bonding nature of a series of intermetallic gold-lanthanide [Au(2)Ln] molecules, where Ln = Eu, Yb, Lu is predicted via the DFT and CASSCF/CASPT2 calculations. The 2c-2e bond model shows a good ...
