Hole Defects Affect the Dynamic Fracture Behavior of Nearby Running Cracks
Published 2018-01-01“…When running cracks propagate near to defects, the crack path deflects toward the defect; the degree of deflection is greater for larger defect diameters. When the running crack propagates away from the defect, the degree of deflection gradually reduces and the original crack path is restored. …”

Synthesis, Characterization and Antimicrobial Activity Study of the Ternary (Poly Anthranilic acid- Graphene Oxide- Zinc Oxide) Nanocomposite
Published 2025-01-01“…The analyses revealed that GO consisted of nanostructures in sheet form, ZnO consisted of rod-shaped structures with dimensions varying between 39 and 63 nm, and the polymer appeared in regular, sphere-like shapes with different diameters. Thermal analyzes of the polymer showed that the polymer (PANA) partially decomposes in the temperature range (145.3-315.6 o C), and completely decomposes at (315.6, 541.9 o C), which means that the polymer is thermally stable. …”
