Modernized Synthesis Technique of Pr2NiO4+δ-Based Complex Oxides Using Low-Temperature Salt Melts

Phases based on layered lanthanide nickelates are considered as promising electrode materials for various electrochemical devices, including solid oxide fuel cells and electrolysis cells. While such compounds may be prepared using either solid state or solution-assisted syntheses, each of these approaches entails certain problems. In the present work, we propose a novel approach for the simple and straightforward preparation of Pr2NiO4+δ-based materials. This approach involves co-melting of initial nitrate components, followed by high-temperature decomposition of the obtained mixture. The developed synthesis method exhibits a number of advantages over conventional techniques, enabling highly dispersed and single-phase powders to be obtained at a reduced synthesis temperature of 1050 °C. Therefore, the results of this work open new possibilities for the cost-effective preparation of Ruddlesden–Popper oxide phases. © 2022 by the authors.Ministry of Education and Science of the Russian Federation, Minobrnauka: 075-03-2021-051/5This work is supported by the Ministry of Education and Science of the Russian Federation, contract no. 075-03-2021-051/5

Block diagram of the automatic model of technical documentation

Abstract The article explores the features of electronic document management of technical documentation of railway automation and telemechanics. The article deals with the synthesis of mathematical models of electronic document management of technical documentation of railway automation and telemechanics. For this purpose, the real processes of creation, verification and use of technical documentation were examined using the example of the process of accounting and control of railway automation and telemechanics devices, which made it possible to identify a structural diagram of a formalized model of technical documentation. A model of electronic document management of technical documentation is created using the mathematical apparatus of finite state machines. A block diagram of an automaton model of technical documentation is developed. The proposed block diagram of a formalized model of technical documentation consists of matrices of external microoperations, internal microoperations, code creation for the following microcomponents. The number of internal states of the firmware is completely determined by the number of logic elements of the algorithms. The size of the matrices depends on the number of operators and logical conditions in the logic circuits of the algorithms.</jats:p
