Alkanethiol self-assembled monolayer on copper polycrystalline thin films: influence on resistivity
(Elsevier, 2018)
Thin polycrystalline copper films of low surface roughness and low electrical resistivity were deposited by physical vapor deposition onto mica at room temperature and in thicknesses ranging from 10 to 80 nm. The crystalline ...
The role of ad-atoms in the coalescence of alkanethiol-passivated gold nanoparticles
(Elsevier, 2013-01)
In the present work we show how the role of ad-atoms and surface imperfections play a key role during the coalescence of thiol-passivated Au nanoparticles (NPs) below 4 nm in diameter. Using spherical aberration corrected ...
Surface Structure and Chemistry of Alkanethiols on Au(100)-(1 × 1) Substrates
(American Chemical Society, 2016-01)
The surface structure of self-assembled monolayers of hexanethiolate (HT) on the Au(100)-(1 × 1) surface has been studied by density functional theory (DFT) calculations and their results compared to scanning tunneling ...
An integrated experimental-theoretical approach to understand the electron transfer mechanism of adsorbed ferrocene-terminated alkanethiol monolayers
(Pergamon-Elsevier Science Ltd, 2018-03-01)
In this work, the electron transfer mechanism of self-assembled monolayers of 6-ferrocenyl-1-hexanethiol (FcC6SH) on Au(111) substrates is addressed from two perspectives. To acquire a complete overview of the involved ...
New insights into the chemistry of thiolate-protected palladium nanoparticles
(American Chemical Society, 2012-04)
This paper establishes the chemical nature of Pd nanoparticles protected by alkanethiolates that were prepared through a ligand place-exchange approach and the two-phase method, first developed for Au nanoparticles by Brust ...
Silver Nanoparticle-Based Arrays into Mesoporous Thin Films Structures for Photoelectronic Circuits
(Bentham Science Publishers, 2019-02)
Background: Silver nanosystems have attracted considerable attention for numerous applications in optoelectronics. The localized surface plasmon of silver nanoparticles embedded into mesoporous titania gives rise to an ...
Electrogravimetric Analysis by Quartz-Crystal Microbalance on the Consumption of the Neurotransmitter Acetylcholine by Acetylcholinesterase
(2012-12-01)
Electrogravimetric analysis was performed on the consumption of the neurotransmitter Acetylcholine (ACh) by Acetylcholinesterase (AChE) in situ and in real time. Michaelis-Menten assumption was achieved by using an enzyme ...

Desenvolvimento de biossensor eletroquímico para diagnóstico de dengue
(Universidade Estadual Paulista (Unesp), 2014-09-26)
A dengue é uma doença infecciosa, não contagiosa, causada por um Flavivirus, transmitido pela picada do mosquito Aedes aegypti infectado. Sua evolução é rápida, o diagnóstico é baseado em sintomas clínicos imprecisos e ...
