Development of bioinspired damage-tolerant calcium phosphate bulk materials

Science and Technology of Advanced Materials, 2023
Improving the damage tolerance and reliability of ceramic artificial bone materials, such as sintered bodies of hydroxyapatite (HAp), that remain in vivo for long periods of time is of utmost importance.

On the applicability of Cu–17Zn–7Al–0.3Ni shape memory alloy particles as reinforcement in aluminium-based composites: Structural and mechanical behaviour considerations

Journal of the Mechanical Behavior of Materials, 2022
The potentials of CuZnAlNi shape memory alloys to serve as viable reinforcement in Aluminium matrix composites (AMCs) was investigated. The AMCs were double stir cast developed, containing 4, 6, and 8 wt% CuZnAlNi particles; and their structural ...

Longevity through DNA damage tolerance [PDF]

Cell Cycle, 2015
The genome in every cell is constantly attacked by a large variety of exogenous and endogenous genotoxins. DNA damage has long been known as causal factor for cancer development and has more recently also been recognized as driving force of the aging process.1 Recent insights have shed light on how organisms respond to DNA damage accumulation by ...

A damage-tolerant glass

Nature Materials, 2011
Owing to a lack of microstructure, glassy materials are inherently strong but brittle, and often demonstrate extreme sensitivity to flaws. Accordingly, their macroscopic failure is often not initiated by plastic yielding, and almost always terminated by brittle fracture.
