Paradoxically stronger, stiffer, and tougher

Interphase tuning for stronger and tougher composites

The development of composite materials that are simultaneously strong and tough is one of the most active topics of current material science. Observations of biological structural materials show that adequate introduction of reinforcements and interfaces, or interphases, at different scales usually improves toughness, without reduction in strength. The prospect of interphase properties tuning m...

How (and why) twisting cycles make individual MWCNTs stiffer

Torsion of MWCNTs entails bumpy nanoscopic interwall phenomena, which gradually enhance the microscopic interwall coupling. This effect is likely to be confined at the ends of the suspended portions of the CNT, the structural changes required to link the outer wall to the inner ones being probably triggered by a complex interaction with the metal deposited onto the nanotube.
