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 ...
Bimetallic AU/AG metal superstructures from macromolecular metal complexes in solid-state
(Sociedad Chilena de Quimica, 2013)
Novel bimetallic Au/Ag superstructures have been prepared from solid-state pyrolysis of the macromolecular complexes Chitosan(MLn/M'Ln)n y PSP- 4-PVP×( MLn/M'Ln)n with MLn = AuCl3 and M'Ln = Ag(CF3SO3). The characterization ...
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. ...
6-Mercaptopurine complexes with silver and gold ions: Anti-tuberculosis and anti-cancer activities
(Elsevier France-editions Scientifiques Medicales Elsevier, 2011-08-01)
Synthesis, characterization and biological studies of silver and gold complexes with 6-mercaptopurine (H2MP) are described. The Ag(I) and Au(I) complexes with HMP-, AgHMP and AuIHMP, were obtained by mixing an acidified ...

"Invisible" silver and gold in supergene digenite (Cu1.8S)
(PERGAMON-ELSEVIER SCIENCE, 2010-11-01)
Despite its potential economic and environmental importance, the study of trace metals in supergene (secondary) Cu-sulfides
has been seriously overlooked in the past decades. In this study, the concentration and mineralogical ...
“influencia del potencial de hidrogeno (ph) y la granulometría sobre el ratio de concentración y él porcentaje de recuperación de oro (au), plata (ag) y cobre (cu) en la flotación de un mineral tipo sulfuro con alto contenido de plata”
(Universidad Nacional de Trujillo, 2016)
Se estudió la flotación de un mineral tipo sulfuro con alto contenido de plata y con presencia de As y Sb. El mineral según análisis químico tiene 5.10 g/TM Au, 700.00 g/TM Ag, 3.9 % Cu, 2.0 % As y 1.2 % Sb. Las variables ...
