Oxidation of gold nanoparticles by Au(III) complexes in toluene
(American Chemical Society, 2012-07-22)
The rapid, stoichiometric oxidation of gold nanoparticles by tetraalkylammonium and tetraalkylphosphonium Au(III) complexes in toluene is reported here. Nanoparticle oxidation proceeds via a comproportionation mechanism ...
Peptides and metallic nanoparticles for biomedical applications
(2007)
In this review, we describe the contribution of peptides to the biomedical applications of metallic nanoparticles. We also discuss strategies for the preparation of peptide-nanoparticle conjugates and the synthesis of the ...
Ordered Au Nanoparticle Array on Au(111) through Coverage Control of Precursor Metal−Organic Chains
(American Chemical Society, 2016-07)
Metal–organic overlayer structures formed by 1,4-phenylene-diisocyanide (PDI) and Au adatoms on Au(111) in UHV, their stability in air, and the tip-induced Au nanoparticle formation on PDI–Au(111) surfaces in air were ...
Morphological and compositional characteristics of bimetallic core@shell nanoparticles revealed by MEIS
(Elsevier Science, 2015-03)
In this paper we report the application of a suitable methodology to study the morphology, structure and composition of core@shell nanoparticles (NPs) systems with polydispersity in the shell thickness, with subnanometer ...
Study of aggregation of gold nanoparticles in chitosan
(2018)
In this work it is reported the synthesis of gold nanoparticles supported in situ in chitosan by solvated metal atom dispersion technique in order to study the inclusion of Au nanoparticles in the biopolymer matrix. To ...
Improved electrocatalysis and electrophoretic deposition due to the strong synergy between Au and Ag nanoparticles
(Wiley Blackwell Publishing, Inc, 2020-08-21)
Here we demonstrate that every time Au and Ag NPs are physically mixed together they outperform their monometallic counterparts upon electrocatalysis of hydroquinone (HQ) and electrophoretic deposition (EPD) coverage.We ...
Cyclodextrin inclusion compound crystals for growth of Cu-Au core-shell nanoparticles
(Springer, 2015)
The preparation and structural elucidation of the 2 alpha-cyclodextrin/decylamine inclusion compound (IC) by proton nuclear magnetic resonance, rotating frame overhauser effect spectroscopy and powder X-ray diffraction ...
Photooxidation of 9-anthraldehyde catalyzed by gold nanoparticles: Solution and single nanoparticle studies using fluorescence lifetime imaging
(American Chemical Society, 2012-11)
The photooxidation of 9-anthraldehyde can be catalyzed by colloidal Au nanoparticles (AuNP) or diamond-supported Au nanoparticles (AuNCD) by using LED excitation at 530 nm. Visible irradiation of the plasmon band of AuNP ...
Selective lactose oxidation in aqueous-phase over Ag-Au bimetallic nanoparticles supported on Al 2 O 3 under mild reaction conditions
(Elsevier B.V., 2018-12-01)
In this work, Au-Ag based catalysts supported on Al 2 O 3 were prepared by a precipitation-deposition method at controlled pH and tested in the selective lactose (LA) oxidation to lactobionic acid (LB) in aqueous phase. ...
