Films were prepared by chronoamperometry (CA) under a constant potential of 1.40 V and adjusting the polymerization charge to 0.55 C.
Chloral hydrate and ethanol, but not urethane, alter the clearance of exogenous dopamine recorded by chronoamperometry in striatum of unrestrained rats.
The stepped potential chronoamperometry (SPC) method [18-20] was applied to measure the transference numbers, and the electronic conductivity and ionic conductivity can be calculated by total electrical conductivity and electronic transference numbers.
The prepared composite sensor was characterized by SEM, cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and chronoamperometry. The results obtained from the experiments for the sensor performance showed that immobilization of GR and PB onto the GCE increased the sensor sensitivity and the response towards target BHA.
The stability of the FeOx/Pt catalyst was evaluated by chronoamperometry measurements (Figure 6) at a potential of 0.2 V in a continuous electrolysis experiment which lasted for 3 h.
The SUDOSCAN, a new screening device for early detection of DPN, has been developed based on different electrochemical principles (reverse iontophoresis and chronoamperometry) to measure sudomotor function through ESC level of hands and feet [17-19].
The linear sweep voltammetry (LSV) curves, corresponding Tafel slopes, and chronoamperometry I-t curves were measured on [Co.sub.x][O.sub.y]/NF and Co-Pi/CoP/NF to estimate their HER activity and long-term stability.
Diffusion coefficients of AML and ATOR were determined on anodically pretreated BDD electrode in BR buffer solution (pH 4.0) by chronoamperometry using Cottrell equation [34].
The chronoamperometry (CA), in the presence of ethanol (Sigma-Aldrich) 1.0 mol [L.sup.-1], was measured at 400 mV versus RHE for 2 hours.
