Open Source Automated Flow Analysis Instrument for Detecting Arsenic in Water
(Elsevier, 2022-04-25)
In this paper the design and implementation of an embedded system based on Flow-Batch methodology with a Quartz Crystal Microbalance (QCM) sensor technology and a commercial FPGA admittance meter is presented to detect the ...
Study of adsorption of citrate on Pt by CV and EQCM
(Elsevier, 2008-07-01)
Citrates are frequently used as additives in the electrodeposition of metals such as manganese in order to improve deposit characteristics and process efficiency. Nevertheless, few studies have been reported on the mechanism ...
Solvent co-deposition during oxygen reduction on Au in DMSO LiPF6
(Elsevier Science, 2014-09)
Rotating ring disk electrode (RRDE) and electrochemical quartz crystal microbalance (EQCM) have been employed for chronoamperometry of the oxygen reduction reaction (ORR) on gold electrodes in O2 saturated LiPF6/DMSO ...
EQCM study during lithium insertion/deinsertion processes in Nb2O5 films prepared by polymeric precursor method
(Elsevier B.V., 2005-03-31)
The electrochemical quartz crystal microbalance (EQCM) technique was used to study two chemically distinct Nb2O5 electrochromic thin films (one pure and the other lithium-doped) during the lithium electroinsertion reaction. ...
Fabrication of phytic acid sensor based on mixed phytase-lipid Langmuir-Blodgett films
(Amer Chemical Soc, 2006-09-26)
This paper reports the surface activity of phytase at the air-water interface, its interaction with lipid monolayers, and the construction of a new phytic acid biosensor on the basis of the Langmuir-Blodgett (LB) technique. ...
The role of hydration on the mechanism of allosteric regulation: In situ measurements of the oxygen-linked kinetics of water binding to hemoglobin
(Biophysical Society, 2003-01-01)
We report here the first direct measurements of changes in protein hydration triggered by a functional binding. This task is achieved by weighing hemoglobin (Hb) and myoglobin films exposed to an atmosphere of 98%, relative ...

Estudos microgravimétricos da deposição de cobre sobre eletrodos de cromo passivado.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2002-11-29)
Recently were obtained in our laboratory results indicating that Cu deposition on
Cr2O3 happens in two steps: at the first one, there is the deposition of an amount
smaller than one Cu monolayer, and at the second one there ...
Preparação e investigação das propriedades de filmes de polipirrol modificados com partículas metálicas magnéticas
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Química - PPGQ, 2005-06-07)
In this work, it was investigated the preparation and characterization of polypyrrole and nickel or cobalt doped popypyrrole. To prepare the doped samples, the monomer was polymerized in a solution containing the metal ...
