AbstractThe fundamentals of a new technique for the cleaning and passivation of (111), (110), and (100) silicon wafer surfaces by hydride groups, which ensure a high surface purity and smoothness at the nanoscale upon long-term storage of the wafers at room temperature in air, are discussed. A new composition of the passivation solution for the long-term antioxidation protection of silicon surfaces is developed. The proposed solution is suitable for the long-term storage and repeated passivation of silicon wafers. The composition of the passivation solution and the conditions of passivation of the silicon wafers in it are described. Silicon wafers treated using the proposed technique can be used for growing epitaxial semiconductor films and different nanostructures. It is shown that only silicon surfaces prepared in this way allow SiC epitaxial films on silicon to be grown by atom substitution. The experimental dependences of the SiC and GaN film structures grown on silicon on the silicon-surface etching conditions are presented. The developed technique for silicon cleaning and passivation can both be used under laboratory conditions and easily adapted for the industrial production of silicon wafers with an oxidation-resistant surface coating.

A model of moisture movement in wood is presented in this paper in a two-dimensional-in-space formulation. The finite-difference technique has been used in order to obtain the solution of the problem. The model was applied to predict the moisture content in sawn boards from pine during long term storage under outdoor climatic conditions. The satisfactory agreement between the numerical solution and experimental data was obtained.

The introduction and active use of information transmission and storage systems in the Ministry of Defense (MoD) of Ukraine form the need to develop ways of guaranteed removal of data from media after their use or long-term storage. Such a task is an essential component of the functioning of any information security system. The article analyzes the problems of guaranteed destruction of information on magnetic media. An overview of approaches to the guaranteed destruction of information on magnetic media of different types is presented, and partial estimates of the effectiveness of their application are given by some generally accepted indicators of performance evaluation. The article also describes the classification of methods of destruction of information depending on the influence on its medium. The results of the analysis revealed the main problems of application of software methods and methods of demagnetization of the information carrier. The issue of guaranteed destruction of information from modern SSD devices, which are actively used in the formation of new systems of information accumulation and processing, became particularly relevant in the article. In today's conditions of development of the Armed Forces of Ukraine, methods of mechanical and thermal destruction are more commonly used today. In the medium term, the vector of the use of information elimination methods will change towards the methods of physical impact by the pulsed magnetic field and the software methods that allow to store the information storage device, but this today requires specialists to develop new ways of protecting information in order to avoid its leakage.
