Measurements of near-ultimate strength for multiwalled carbon nanotubes and irradiation-induced crosslinking improvements.
Bei Peng,Mark A Locascio,Peter Zapol,Shuyou Li,Steven L. Mielke,George C. Schatz,Horacio D. Espinosa +6 more
TL;DR: Multiwalled carbon nanotubes with a mean fracture strength >100 GPa are reported, which exceeds earlier observations by a factor of approximately three and are in excellent agreement with quantum-mechanical estimates for nanot tubes containing only an occasional vacancy defect, and are approximately 80% of the values expected for defect-free tubes.
Journal ArticleDOI
On the mechanics of mother-of-pearl: a key feature in the material hierarchical structure
TL;DR: In this article, the structure of nacre is described over several length scales and the tablets were found to have wavy surfaces, which were observed and quantified using various experimental techniques.
Journal ArticleDOI
Merger of structure and material in nacre and bone - Perspectives on de novo biomimetic materials
TL;DR: In contrast to synthetic materials, evolutionary developments in biology have resulted in materials with remarkable structural properties, made out of relatively weak constituents, arranged in complex hierarchical patterns as discussed by the authors, which can exhibit superior levels of strength and toughness.
Journal ArticleDOI
An Experimental Investigation of Deformation and Fracture of Nacre–Mother of Pearl
TL;DR: In this paper, the uniaxial tension experiment performed on miniature nacre specimens was performed, and specific features of the microstructure and their relevance to associated toughening mechanisms were identified.
Journal ArticleDOI
Elasticity size effects in ZnO nanowires--a combined experimental-computational approach.
TL;DR: The computational results demonstrate similar size dependence, complementing the experimental findings, and reveal that the observed size effect is an outcome of surface reconstruction together with long-range ionic interactions.
