2D nucleation and growth phenomena in UPD of Cd on Ag(111) and Ag(100)
(The Electrochemical Society, 2010-03)
Underpotential deposition (UPD) of Cd on Ag single crystal substrates has been studied by in situ scanning tunneling microscopy (STM) and electrochemical measurements. On Ag(111) the UPD process starts with formation of ...
Effect of metallic Ag growth on the electrical resistance of 3D flower-like Ag4V2O7 crystals
(2017-06-01)
In this communication, we report for the first time the nucleation and growth of metallic Ag nanoparticles on the surface of 3D flower-like Ag4V2O7 crystals, induced by accelerated electron beam irradiation. The growth of ...
Silver ion release from electrodes of nanotubes of TiO2 impregnated with Ag nanoparticles applied in photoelectrocatalytic disinfection
(Elsevier B.V., 2014-03-15)
Self-organized TiO2 nanotubes arrays electrodes were impregnated with 0-16% of Ag nanoparticles (Ti/TiO2-Ag) using different procedures. The electrodes were characterized by X-ray diffraction (XRD), scanning electron ...
Differentiated interactions in phosphate solutions: Comparing Ag(111) and Ag(100) surfaces
(Elsevier Science Sa, 2017-08)
The electrochemical behavior of phosphate species on Ag(111) and Ag(100) single crystal surfaces was studied by experimental techniques and theoretical calculations. Characteristic cathodic/anodic potential peaks (Vp) ...
Differential physiological responses of a biogenic silver nanoparticle and its production matrix silver nitrate in Sorghum bicolor
(2021-01-01)
Silver nanoparticles (AgNP) have been extensively applied in different industrial areas, mainly due to their antibiotic properties. One of the environmental concerns with AgNP is its incorrect disposal, which might lead ...
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 ...
Preparation of calcined hydrotalcite/TiO2-Ag composite and enhanced photocatalytic properties

Avaliação antibiofilme e anticariogênica de nanocompósitos formados por polifosfatos de sódio e flúor associados à nanopartículas de prata : estudo in vitro
(Universidade Estadual Paulista (Unesp), 2018-05-04)
O objetivo deste estudo foi sintetizar e caracterizar nanocompósitos formados por polifosfatos (trimetafosfato de sódio (TMP) ou hexametafosfato de sódio (HMP)) e flúor (F) associados à nanopartículas de prata. Esses ...
Elucidating the real-time Ag nanoparticle growth on alpha-Ag2WO4 during electron beam irradiation: experimental evidence and theoretical insights
(Royal Soc Chemistry, 2015-01-01)
Why and how Ag is formed when electron beam irradiation takes place on alpha-Ag2WO4 in a vacuum transmission electron microscopy chamber? To find an answer, the atomic-scale mechanisms underlying the formation and growth ...
Design and Construction of Solid State Ag/AgCl Reference Electrodes Through Electrochemical Deposition of Ag and AgCl Onto a Graphite/Epoxy Resin-Based Composite. Parte 1: Electrochemical Deposition of Ag Onto a Graphite/Epoxy Resin-Based Composite
(2011)
In order to design and build solid state Ag/AgCl reference electrodes, the thick-film and thin-film techniques are frequently used to obtain a silver coating on a substrate that is subsequently chlorinated. In this part ...
