Journal ArticleDOI
Super‐Compressible Foamlike Carbon Nanotube Films.
Anyuan Cao,Pamela L. Dickrell,W. Gregory Sawyer,Mehrdad N. Ghasemi-Nejhad,Pulickel M. Ajayan +4 more
TL;DR: In this article, the authors report that freestanding films of vertically aligned carbon nanotubes exhibit super-compressible foam-like behavior under compression and can fully unfold to their original length upon load release.
Journal ArticleDOI
Distribution of pentagons and shapes in carbon nano-tubes and nano-particles
TL;DR: In this article, high-resolution electron microscopy images of carbon nano-tubes and nano-partcles are presented, and the symmetric and asymmetric distribution of pentagons at their end surfaces is analyzed.
Journal ArticleDOI
Nonlinear Optical Properties and Temperature-Dependent UV–Vis Absorption and Photoluminescence Emission in 2D Hexagonal Boron Nitride Nanosheets
Pathik Kumbhakar,A. K. Kole,Chandra Sekhar Tiwary,Chandra Sekhar Tiwary,Subrata Biswas,Soumya Vinod,Jaime Taha-Tijerina,Udit Chatterjee,Pulickel M. Ajayan +8 more
TL;DR: In this article, the reverse saturable absorption occurs in aqueous colloidal solutions of hexagonal boron nitride (h-BN) with a very large two-photon absorption cross section (sigma(2PA)) of approximate to 57 x 10(-46) cm(4) s(-1) photon(-1).
Journal ArticleDOI
Synthesis of large-scale atomic-layer SnS 2 through chemical vapor deposition
Gonglan Ye,Yongji Gong,Yongji Gong,Sidong Lei,Yongmin He,Bo Li,Xiang Zhang,Zehua Jin,Liangliang Dong,Jun Lou,Robert Vajtai,Wu Zhou,Pulickel M. Ajayan +12 more
TL;DR: In this article, the chemical vapor deposition (CVD) growth of atomic-layer SnS2 with a large crystal size and uniformity was reported, with an octahedral lattice made of two atomic layers of sulfur and one atomic layer of tin.
Journal ArticleDOI
Growth of carbon micro-trees
TL;DR: This work describes the spectacular growth of micron-sized tree-like carbon structures produced by chemical vapour deposition of methane without the use of any catalysts.
