This paper is devoted to the mathematical modeling of the field emission diode system. The diode system is consists of the infinitely thin field emitter as a cathode and a plane anode. The emitter substrate is a plane. The interior of system domain is filled with two different dielectrics. The electrostatic potential distribution is found by the method of separation of variables for the Laplace’s...
This article is devoted to the field emitter of the arbitrary shape mathematical modeling. The axially symmetrical diode system with a field cathode on a plane substrate and a plane anode is under investigation. The effect of the field emitter is simulated using the charged circular lines to solve the boundaryvalue problem so that the zero electrostatic equipotential coincided with the cathode surface...
In this work the axially symmetrical diode system based on a sharp-edged field cathode on a plane substrate is under investigation. Anode is a plane. All interior area of the system is filled with two dielectrics. To solve the boundary-value problem the variable separation method is used and an effect of the field cathode is simulated using the charged circular lines. The electrostatic potential distribution...
Microbial fuel cell (MFC) is a promising technology that uses bacteria to produce electricity through chemical reactions. While MFC is highly efficient, environment-friendly, and independent from limited sources, control-oriented modeling and control studies that aim to improve the power output have been limited. In this paper a control-oriented dynamic model with state-space representation is presented...
The electrochemical oxidation of atrazine on Ti/SnO2-Sb2O5/PbO2 electrode was studied by cyclic voltammetry in this paper. The electrochemical behaviour of the electrode in sodium sulfate solution and in the mixture solution of sodium sulfate and atrazine has been studied. The experimental results of cyclic voltammetry showed that acidic media was suitable for efficient electrochemical oxidation of...
The electrochemical oxidation of imazethapyr at Ti/SnO2-Sb2O5/PbO2 electrode was investigated by cyclic voltammetry, and the oxidation mechanism of imazethapyr was primarily studied in this paper . Sodium sulfate was used as the electrolyte of the substrate solutions. The experimental results of cyclic voltammetry show that acidic media is suitable for efficient electrochemical oxidation of imazethapyr...
This paper reports the experimental evidence of a new minority carrier injection mechanism. The new physical mechanism earlier proposed by us is based on the use of a MOS inversion layer as a minority carrier injector as part of a dynamic junction. Unlike in conventional devices, the physical existence of the emitter and the carrier injection of such a junction is entirely controlled by the MOS gate...
Corrosion in Co-Ni-O film, which is adopted as the magnetic layer in metal evaporated tape media, was examined through aging tests, measurements of anode polarized characteristics, and analysis of both chemical bonding by ESCA and of crystallographic characteristics by RHEED. The following results were obtained. 1) The experimental results for exposure tests were strongly correlated with the anode...
