Profile Summary

I am a Master’s student in Physics and a Junior Researcher at the Research Institute of Natural Sciences, Nanotechnologies and New Materials of Khoja Ahmet Yassawi International Kazakh-Turkish University. My academic and research background is focused on materials science, condensed matter physics, nanostructured coatings, and functional materials. My research experience includes participation in several scientific and grant-funded projects related to the development and characterization of advanced materials and coatings. In particular, I have been involved in projects on ZrCN-, Cr₃C₂–NiCr-, and quasicrystal-based protective coatings deposited by the HVOF method, as well as studies on hydrogen storage materials based on Pd–Ti–Mg and metal hydride systems. I have also contributed to research related to CVD processes, surface modification of materials, and the investigation of microstructure, phase composition, tribological behavior, microhardness, and coating adhesion. Through my research activities, I have gained practical experience with modern materials characterization techniques, including X-ray diffraction (XRD), scanning and transmission electron microscopy (SEM/TEM), energy-dispersive spectroscopy (EDS/EDX), microhardness testing, tribological testing, and adhesion strength evaluation of coatings. I am able to interpret experimental results, correlate microstructure and phase composition with physical and mechanical properties, and present scientific findings in a clear and structured form. My professional skills include scientific data processing and visualization in Origin, XRD interpretation and structural analysis using FullProf and VESTA, microstructural image analysis, and preparation of scientific figures, tables, posters, presentations, and manuscripts. I also have experience in academic writing, scientific translation, and preparing materials for conferences, publications, and reviewer responses.
