Summary of the subject: The discipline "Physics and Chemistry of Surfaces and Nanomaterials Technology" explores the interdependence between chemical composition, energy state, structure, and properties of material surface layers, as well as the changes in their functional properties aimed at increasing the durability and reliability of machine parts and structures. The curriculum covers the fundamentals of physical materials science, surface structure, physicochemical and technological properties of materials, methods of surface layer treatment, and the creation of functional coatings. The course also includes the study of nanomaterials—their structure, properties, methods of production, and application. Students become familiar with modern technologies, innovative analysis methods, and the theoretical principles distinguishing nano- from macroscale objects. They acquire skills in determining microstructure and physico-mechanical properties of materials, as well as an understanding of the prospects for the development of materials science and the industrial implementation of scientific results.

Preparation, execution, and defense of reports on practical work are evaluated at 15 points per task. Preparation of an essay on an individual assignment is evaluated at 10 points. The purpose of the final credit-based assessment is to evaluate the depth of a student's understanding of the course content, the logic and interrelations between its sections, and the ability to creatively apply acquired knowledge. It also assesses the ability to form a reasoned position on a specific professional issue stemming from the course content. Assessment of oral and written test tasks in the final examination depends on the type of question: Correct answers to closed test questions of the first level of complexity with a single correct option are graded 4 points; incorrect answers receive 0 points. No partial credit is awarded for these questions. Correct answers to closed test questions of the second and third levels of complexity (with multiple correct options, matching, embedded answers, fill-in-the-blanks, or sequencing) are graded 7 to 10 points, depending on the complexity. Evaluation criteria for responses and tasks include: Completeness of the answer; Consistency, systematic approach, and justification; Logical flow, language accuracy; Analytical thinking, ability to compare and draw conclusions; Neatness and presentation of written work.
