Determination of Crack Resistance of the Cover and Slide Glass by Indentation Method with the Visualization Using Atomic Force Microscopy
Lapitskaya, V. A.; Kuznetsova, T. A.; Chizhik, S. A. (БНТУ, 2024)Crack resistance of two types of glass was studied – cover glass (0.17 mm thick) and slide glass (2 mm thick) using an improved technique through the use of the probe methods, which makes it possible to increase the accuracy of determining the crack resistance of glass. Colorless silicate glass was used. Crack resistance was determined by the Vickers pyramid indentation method. ...2024-05-23 -
Influence of Temperature from 20 to 100 °C on Specific Surface Energy and Fracture Toughness of Silicon Wafers
Lapitskaya, V. A.; Kuznetsova, T. A.; Chizhik, S. A. (БНТУ, 2023)The influence of temperature in the range from 20 to 100 °C on the specific surface energy and fracture toughness of standard silicon wafers of three orientations (100), (110) and (111) was studied. Silicon wafers were heated on a special thermal platform with an autonomous heating controller, which was installed under the samples. At each temperature, the samples were kept for ...2023-12-12 -
Methods for Accuracy Increasing of Solid Brittle Materials Fracture Toughness Determining
Lapitskaya, V. A.; Kuznetsova, T. A.; Chizhik, S. A.; Warcholinski, B. (БНТУ, 2022)Method for determining of the fracture toughness of brittle materials by indentation is described. The critical stress intensity factor KIC quantifies the fracture toughness. Methods were developed and applied to improve the accuracy of KIC determination due to atomic force microscopy and nanoindentation. It is necessary to accurately determine parameters and dimensions of the ...2022-04-06 -
Nanostructured Coatings Based on Langmuir–Blodgett Films of Perfluorodecanoic Acid for Flexible Sensors for the Analysis of Lead Ions in Water
Melnikova, G. B.; Sapsaliou, D. V.; Tolstaya, T. N.; Korolkov, I. V.; Chizhik, S. A.; Zhumanazar, N. N.; Baranova, A. S.; Zdorovets, M. V. (БНТУ, 2024)As a result of anthropogenic activities, the environment is polluted by heavy metals. The most important task is to find methods to control their content in water. Track-etched membranes (TeMs) can be relatively easily modified by nanometer layers of functional materials with using the Langmuir‒Blodgett technique, which makes it possible to specifically change the structural, ...2024-05-23 -
Optimization of the Emitting Coil of a Hardware-Software Complex for Study of Low-Frequency Electromagnetic Radiation’s Shielding Effectiveness
Kanafyev, O. D.; Trukhanov, A. V.; Zubar, T. I.; Chizhik, S. A.; Grabchikov, S. S. (БНТУ, 2021)Optimization of the radiation coil of the hardware-software complex for studying the effectiveness of shielding of low-frequency electromagnetic radiation will make it possible to assess the effectiveness of shielding coatings at a higher level. This fact will make it possible to develop coatings with improved characteristics. The purpose of this work was to determine the optimal ...2021-03-18
