Advanced Healthcare Materials, EarlyView.Hybrid wrinkled topographies coordinate immune, tissue, and bacterial interactions. The surfaces promote osteointegration, tune macrophage polarization, and inhibit biofilm formation, highlighting a multifunctional strategy for next‐generation implant design.

Advanced Healthcare Materials, EarlyView.Metallofullerenol Sc3N@C80(OH)18 demonstrates strong radioprotective properties as a scavenger of both short‐ and long‐lived radicals. The study reveals protection of human erythrocytes from γ‐radiation–induced biochemical damage via post‐irradiation removal of primary and secondary reactive oxidants, supported by pulse radiolysis kinetics.

Current Opinion in Cell Biology, 2016
Accurate chromosomal DNA replication is fundamental for optimal cellular function and genome integrity. Replication perturbations activate DNA damage tolerance pathways, which are crucial to complete genome duplication as well as to prevent formation of deleterious double strand breaks.

Damage Tolerance of Composite Cylinders
SAE Technical Paper Series, 1983<div class="htmlview paragraph">The fracture of pressurized graphite/epoxy cylinders was investigated and their damage tolerance assessed. The cylinders were 610 mm (24 in) long and 305 mm (12 in) in diameter and were fabricated from Hercules A370-5H/3501-6 prepreg cloth in 4-ply configurations: (0,45)<sub>s</sub> and (45,0)<sub>

International Journal of Fatigue, 1994
This paper is dedicated to my friend and colleague Professor Dr Jaap Schijve, required to retire like many good aircraft components according to a «safe life» criterion but who is still young in mind, body and spirit, has not yet reached his unfactored endurance limit, and who could continue subject to a needed change in philosophy to «retirement for ...

Modelling of Continuing Damage for Damage Tolerance Analysis
2011This paper presents and compares two continuing damage modelling approaches: a simplified approach, which approximately models diametrical cracks as two independent radial cracks, and an improved approach that accurately models the interaction between the cracks.

Damage tolerant design demonstration
25th Structures, Structural Dynamics and Materials Conference, 1984This paper presents static failure strengths at various environments and room temperatureldry fatigue thresholds of delaminated and impact damaged graphitelepoxy coupons and stringer-stiffened wing skin panels. Damage due to external low velocity impact, in terms of either static failure strength or normalized fatigue threshold, is found to be more ...

Damage-tolerance strategies for nacre tablets
Journal of Structural Biology, 2016Nacre, a natural armor, exhibits prominent penetration resistance against predatory attacks. Unraveling its hierarchical toughening mechanisms and damage-tolerance design strategies may provide significant inspiration for the pursuit of high-performance artificial armors.

The spirit of Glare is its crack bridging mechanism, which provides superior damage tolerance properties. Depending on the specific property, Glare shows either monolithic metal or composite behaviour. This challenges the definition of strength justification and certification procedures.
