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. …

Evaluation of Crystallinity in Talc/Poly-styrene Composites by using FTIR and XRD
Abstract: Over the decade, polymers have found their usage in almost all types of industries ranging from food and beverage packaging to automobile industries. Though the polymers are considered highly inert and chemically stable, their performance under mechanical loading is not at par with their metallic counterparts. Thus, polymer composites have started gaining popularity over the years, but their properties are poorly understood. In this study, the effect of talc addition …
