This is an important task because water-based suspensions are key components of many technological processes, including ceramic production, medicine, biotechnology and cosmetology. The relevance of the work is determined by the need to create a new methodology for the study of aqueous suspensions, since the existing methods for the study of these suspensions have a number of limitations, therefore, the search for new and effective methods for the study of these materials remains an important task. The method of surface plasmon resonance allows for real-time research without using markers and markings, which makes it more efficient and accurate compared to other methods of researching water-based suspensions. popup.description2  The aim of the study is to develop a methodology based on the phenomenon of surface plasmon resonance (SPR) for investigating aqueous suspensions, which are crucial components in technological processes such as ceramic manufacturing, medicine, biotechnology, and cosmetology. The research methods included thermometry, voltammetry, SPR spectroscopy, refractometry, atomic force microscopy, and spectroscopy in the visible and IR ranges. Key results of the study: 1) Aqueous suspensions of "Polyarite": The influence of particle concentration and size on the response of the SPR sensor was investigated. The relevance of using SPR devices for monitoring opaque suspensions was established. The issue of the wear resistance of gold nanolayers was proposed to be resolved by applying protective coatings. 2) ZnO coating technologies: A sol-gel deposition method for ZnO films on microscope glass and gold films of SPR sensors was developed. Thin films provided thermal stability up to 500 °C and protection against mechanical wear (increased resistance to destruction by 27 times). The structure, optical, and electrical characteristics of ZnO films were studied. Methods for measuring electrical conductivity with minimal surface impact were developed. 3) Suspension control: The SPR method was used to analyze aqueous suspensions of MKF-4 slurry and paraffin-based suspensions (boron nitride slurry). The possibility of controlling nanoparticle content and distribution, essential for producing thermally resistant military products, was demonstrated. The study confirmed the effectiveness of sol-gel coating technology in improving the durability of sensor elements. The results will contribute to the advancement of suspension monitoring methods in industrial applications. Product Description popup.authors Fedorenko Artem V. popup.nrat_date 2025-01-22 Close
