Determination of Compatibility of Polymer Systems and Study of Chemical Properties of their Mixtures
Abstract: We have obtained mechanical strength of materials as a result not by synthesizing new polymers, but by using industrial polymers. We have developed a technology for obtaining new composite materials based on industrial multi-tonnage polymers of high-strength polyethylene (HSPE), polyvinyl chloride (PVC), polyurethane thermoplastic elastomer (DUTEP), butyl rubber (BR), chlorocarboxylate polyethylene (CCPE), ethylene propylene rubber (EPR). To obtain a composition from these polymers, their mixture compatibility was first determined using …

Crystal Defects and Their Characterization in Modern Materials Science
Abstract: The physical and chemical properties of crystalline solids are fundamentally dictated by deviations from structural perfection, known as crystal defects. From the point-scale vacancies that drive diffusion to the planar boundaries that determine mechanical strength, defects serve as the primary "tuning knobs" in material design. This review provides a comprehensive examination of point, line, and planar defects, exploring their formation energetics and their role in plastic deformation via crystallographic slip. …

Thermodynamic Irreversibility in Semen Transport
Abstract: Sperm ejaculation is a vital reproductive process that involves both complex biological functions and energetic mechanisms. Beyond the physiological aspects, thermodynamics offers a framework to analyze energy conversion, exergy use, and irreversibility during sperm activity. ATP provides the main source of exergy for motility, but part of this energy is inevitably lost as heat and entropy generation, reflecting inefficiencies in the process. Because heat regulation directly affects metabolic rates, motility …
