Uniqueness of the solution of one class of Volterra-Stieltjes linear integral equations of the third kind = Единственность решения одного класса линейных интегральных уравнений Вольтерра-Стилтьеса третьего рода

Avıt ASANOV | Kalıskan MATANOVA | Eliza Apsamat Kızı

In this paper, the question of uniqueness of the solution for one class of Volterra-Stieltjes linear integral equations of the third kind is investigated. The notion of derivative with respect to an increasing function was introduced by A. Asanov in 2001 and plays special role in the study. This notion is a generalization of the usual concept of a derivative function and is an inverse operator for one class of the Stieltjes integral. Basing on idea of such derivative, using the method of integral transformations and the method of non-negative quadratic forms, the uniqueness theorems for the so ...Более

High-performance carbon black electrode for oxygen reduction reaction and oxidation of atrazine by electro-Fenton process

Mehmet KOBYA

The aim of this study is to produce an electrode that can be used in H2O2 production and Electro-Fenton (EF) process by an effective, cheap, and easy method. For this reason, a superhydrophobic electrode with a higher PTFE ratio and high thickness was produced with a simple press. The produced electrode was used in the production of H2O2 and mineralization of Atrazine. First, the effect of pH, cathode voltage, and operation time on H2O2 production was evaluated. The maximum H2O2 concentration (409 mg/L), the highest current efficiency (99.80? and the lowest electrical energy consumption (3.16 ...Более
