In this work, we demonstrate for the first time the possibilities of the extraction–pyrolytic method (EPM) for the production of nanocrystalline TiO2 powders. A titanium-containing precursor (extract) was prepared by liquid–liquid extraction using valeric acid C4H9COOH without diluent as an extractant. Simultaneous thermogravimetric analysis and differential scanning calorimetry (TGA–DSC), as well as the Fourier-transform infrared (FTIR) spectroscopy were used to determine the temperature conditions to fabricate TiO2 powders free of organic impurities. The produced materials were also characterized by X-ray diffraction (XRD) analysis and transmission electron microscopy (TEM). The results showed the possibility of the fabrication of storage-stable liquid titanium (IV)-containing precursor, which provided nanocrystalline TiO2 powders. It was established that the EPM permits the production of both monophase (anatase polymorph or rutile polymorph) and biphase (mixed anatase–rutile polymorphs), impurity-free nanocrystalline TiO2 powders. For comparison, TiO2 powders were also produced by the precipitation method. The results presented in this study could serve as a solid basis for further developing the EPM for the cheap and simple production of nanocrystalline TiO2-based materials in the form of doped nanocrystalline powders, thin films, and composite materials.

BASE
This study is aimed at the development of a guideline for analysis of the economic activity of an enterprise to control and ensure the interaction of tasks and functions of management in the current and strategic aspects in the conditions of innovative development. The proprietary methodology for enterprise management control system formation is developed. The concept of matrices of analysis and interaction between the functions of the enterprise management is introduced. The matrix of operational control and management, the matrix of strategic control and management, the matrix of integrated control and management are considered by the authors. The concept of enterprise management control is considered herein. The objectives of the management control system in the modern economy are also described. The key role of control in the implementation of the current and strategic objectives of the enterprise management is substantiated. The proposals are formulated to improve the control function at the enterprise with the help of new information technologies. Based on the proprietary methodology of matrix analysis and interaction of objectives and functions of the enterprise management system, the algorithm for the formation of a system of integrated flexible internal control is developed. ; peer-reviewed
