Towards Crack-Resistant Polycrystalline Zirconia Shape-Memory Ceramics with Low Hysteresis
… full potential: i) polycrystals catastrophically crack during the martensitic transformation, and ii) the transformation exhibits a large hysteresis of over 150 K. It is yet unknown what drives these phenomena and how they can be avoided. In this thesis, these phenomena are systematically …

Crack-resistant and self-healing cut-off wall materials incorporating polymers and minerals
… and reliability. This PhD research develops crack-resistant and self-healing cut-off wall materials incorporating polymers and minerals. The overall performance of four additives, including superabsorbent polymers (SAPs), oil sorbent polymers, reactive magnesia (MgO) pellets, and …

Triple junctions and low angle boundaries
Certain properties, such as cracking or corrosion, can occur mainly along grain boundaries. Certain types of boundaries may be more beneficial for material properties. The way that the boundaries are connected in a material can determine how boundaries will affect properties, for instance, whether …

Study of Mechanical Properties of PVA Fiber-Reinforced Concrete With Raman Spectroscopic Analysis
… be improved to provide upgraded construction. Crack resistant and durable concrete has always been a major goal for engineers. Many approaches have been tried to make concrete a better construction material. Fiber reinforcement is an approach which has been shown to improve the quality and …

Characterization of the Organic Matrix of Mature Human Tooth Enamel: Structure, Macromolecular Composition and Effect of Radiotherapy
… its innermost region, which is tougher and more crack resistant than the outer bulk phase. Although the enamel organic matrix is regarded to contribute to these properties, its structure and macromolecular composition remain largely unknown. To characterize these unknowns, the hypotheses tested …
