Effect of thiourea concentration on the electrochemical behavior of gold and copper electrodes in presence and absence of cu(ii) ions
(SOC CHILENA QUIMICA, 2009)
The effect of thiourea (TU) concentration on copper electrodeposition was studied employing cyclic voltammetry and electrochemical crystal quartz microbalance techniques. It was found that the polarization effects are ...
Carbon dioxide adsorption studies on delafossite CuFeO2 hydrothermally synthesized
(2016)
Delafossite CuFeO2 oxide was synthesized by a hydrothermal technique using Cu2O and FeOOH as precursors with the addition of fused NaOH as mineralizer. The amount of rhombohedral and hexagonal delafossite phase formed ...
On the dramatic increase with chain length of the oxidazability of linear saturated aliphatic alcohols on gold in alkaline media
(2015)
The electrooxidation of linear saturated aliphatic alcohols from C1 to C8 on gold in alkaline media has been studied by cyclic voltammetry and with an electrochemical quartz crystal microbalance. The current density of ...
Hydration effects on the structural properties and haem-haem interaction in haemoglobin
(Royal Soc Chemistry, 2003-01-01)
Direct and simultaneous measurements of hydration water content and protein conformation have been performed using quartz crystal microbalance and visible absorption spectroscopy. Equilibrium and kinetics of methaemoglob ...
Mass/charge balance as a tool to estimate dimensional change in polypyrrole-based actuators
(Elsevier B.V., 2006-01-01)
The deconvolution of the voltammograms of polypyrrole electrochemistry has proved to be possible through the electrochemical quartz crystal microbalance data using the F(dm/dQ) function. This deconvolution allows the ...
