The electrochemical behavior of nickel, Inconel 600, Incoloy 800 and 316 stainless steel electrodes in different concentration of NaOH solution was investigated using the cyclic voltammetry technique (CV). All the curves in the anodic branch of the CV are characterized by anodic dissolution peak (A), passive region (B), anodic dissolution peak (C) before oxygen evolution. In the case of the cat...

Interfacial reactions of cytochrome c3 at a graphite electrode were studied in a neutral medium by means of the differential pulse and cyclic voltammetry. It was found that ferricytochrome c3 yielded three cathodic peaks G, d i and Cm at potentials of —0.3 to —0.5 V (vs. Ag/AgCl reference electrode) on the voltammograms. Upon anodic polarization this protein yielded two anodic peaks Ai and An a...

Synthetic homopolyribonucleotides poly(A), poly(U), poly(C), and poly(G), poly(A, G, U), apurinic acid and native and denatured DNA from calf thymus were analyzed by means of cyclic voltammetry (CV) using a hanging mercury drop electrode. It was shown that guanine containing polynucleotides, i.e. poly(G), poly(A, G, U) and DNA yield an anodic peak of guanine in the vicinity of a potential of -0...

The rapid inward migration of fluoride ions in growing anodic titanium oxide under a high electric field has been elucidated by anodizing a Ti-12 at% silicon alloy, where film growth proceeds at nearly 100% efficiency in selected electrolytes. Further, incorporated silicon species in the anodic film are immobile, acting as marker species. The migration rate of fluoride ions is determined precis...

Abstract: The LC resonator-based passive pressure sensor attracts much attention because it does not need a power source or lead wires between the sensing element and the readout system. This paper presents the design and manufacturing of a passive pressure sensor that contains a variable capacitor and a copper-electroplated planar inductor. The sensor is fabricated using silicon bulk micro-mac...

Polarographic studies of potassium isobutyl xanthate at a mercury electrode reveal that the product of an anodic reaction is strongly adsorbed at the mercury surface, as indicated by a prewave. The adsorbed film greatly affects the characteristics of the anodic wave of xanthate in an aqeous medium. The current of total wave is proportional to the concentration of xanthate from 0.32 to 1.6 mM.

A simple method for fabrication of highly ordered gold nanorod film is introduced in this article. The procedure is based on thermal evaporation of gold into a porous anodic alumina film (PAA). The PPA film was fabricated by combining the hard and mild anodization. This combination effectively decreases the processing time of fabrication of highly ordered porous anodic alumina film with c...

Several techniques for fabrication of nanochannels on both glass and silicon substrates have been investigated. The techniques investigated here include glass to glass anodic bonding with an intermediate layer of amorphous silicon, silicon to silicon anodic bonding with an intermediate layer of glass, and AuAu thermo-compression bonding of silicon wafers. In each case, the conduit’s height is d...

With the aim of promoting the Ni/Ce0.8Gd0.2O2-δ (Ni/GDC20) cermet anodic performance of low temperature solid oxide fuel cell (LT-SOFC) [1], nanostructuring platinum nanoparticles on NiO/GDC composite was done by single-step wet-infiltration of hexachloroplatinic acid hexahydrate (H2PtCl6.6H2O) precursor on NiO/GDC20 composite. The anodic polarization resistance was measured using symmetr...
