Bare electrode, welding bath, the neighbouring parts to arc and basic metal are formed through blowing gas org as mixture that is provided from outside against atmosphere pollution and is suitable for the area Because of the melting electrode and use of inert gas, the method is called Metal Inert Gas (MIG) welding.
The DET of catalase was investigated either on modified or on bare electrode to identify the optimal conditions for [H.sub.2][O.sub.2] detection.
The proposed nanocomposite sensor showed satisfactory results and sharp oxidation peaks of AA, DA, UA, and FA as compared to a bare electrode during SWV measurement as shown in Figure 1(c).
The Py/NptPy-TTAB copolymer was used to modify working electrode due to its better grip on the bare electrode surface.
SWCNT modified SPCE was prepared by depositing 10 [micro]M dispersion of SWCNT onto the surface of the bare electrode followed by drying it at room temperature for an overnight and is denoted as SPCE/SWCNT.
The results reveal that the contact angles of the modified electrode surfaces decreased compared with that of the bare electrode, showing that the electrode surfaces were modified successfully and hydrophilicity was introduced to the surface.
Figure 1 illustrates the results of impedance spectroscopy measurements on the bare electrode, whereas Figure 2 presents the results obtained with the electrode coated with s-BLM (a) and after interaction for 10 min with 5.0 g/L of fructooligosaccharides from chicory (b) in 0.1 mol/L KCl solution containing 1 mmol/L Fe[(CN).sub.6.sup.4-/3-] measured at the formal potential of the system.
As shown in Figure 4, TCh would be oxidized on both bare electrode and modified electrode and formed anodic peak.
Protein Electrons transport in the bare electrode surface is very slow; therefore peak redox proteins are usually not visible.

Figure 4 shows the absorbance spectra of four nanoporous Ti[O.sub.2] electrodes: a bare electrode, DEDTC-treated (for 30 min.) electrode, a dye-adsorbed electrode, and a dye-adsorbed electrode after DEDTC treatment for 30 min.
However, the electrochemical techniques using the modified electrodes are highly selective and sensitive according to the other electrochemical techniques combined with bare electrodes.
