TL;DR: It is shown that a helical nanotube yarn can be overtwisted into highly entangled, macroscopically random but locally organized structures, consisting of mostly double-helix segments intertwined together, which represent a complex self-assembled system with applications as large-range strain sensors and robust rotational actuators.

TL;DR: In this article, the Fourier and Laplace transforms were used to analyze the dynamic and steady response of non-homogeneous composite materials with arbitrary varying material properties through thickness direction and the crack number.

TL;DR: In this article, the effect of voids on the strength of composite laminates has been investigated in terms of the fracture parameters involved in the fracture criterion and the critical void content has been estimated for each case both for void content and ultrasonic attenuation.

TL;DR: In this paper, an electroactive thermoset styrene-based shape memory polymer (SMP) nanocomposite filled with nanosized (30?nm) carbon powders was investigated.

TL;DR: It is shown that CNTs can be made into a highly twisted yarn-derived double-helix structure by a conventional twist-spinning process and indicated that it is possible to create higher-level, more complex architectures from CNT yarns and fabricate multifunctional nanomaterials with potential applications in many areas.
