Journal ArticleDOI
Quantitative analysis of the temperature dependency in Raman active vibrational modes of molybdenum disulfide atomic layers.
TL;DR: It is found that both planar and out-of-plane characteristic modes in molybdenum disulfide atomic layers are highly sensitive to temperature variations, and this temperature dependency is linear and can be fully explained by the first-order temperature coefficient.
Journal ArticleDOI
Nanocomposite toughness from a pull-out mechanism
TL;DR: In this paper, the authors quantify nanocomposite toughness through a reanalysis for nanotubes of the Cottrell-Kelly-Tyson (CKT) model, of the definition of critical length, and of the energy dissipation model for pull-out.
Journal ArticleDOI
Macroscopic nanotube fibers spun from single-walled carbon nanotube polyelectrolytes.
Chengmin Jiang,Avishek Saha,Colin C. Young,Daniel P. Hashim,Carolyn E Ramirez,Pulickel M. Ajayan,Matteo Pasquali,Angel A. Martí +7 more
TL;DR: In this work, single-walled carbon nanotube (SWCNT) fibers were produced from SWCNT polyelectrolyte dispersions stabilized by crown ether in dimethyl sulfoxide and coagulated into aqueous solutions and showed liquid crystalline behavior under polarized optical microscopy.
Journal ArticleDOI
Insight into the hydrogen evolution reaction of nickel dichalcogenide nanosheets: activities related to non-metal ligands
Yuancai Ge,Shang-Peng Gao,Pei Dong,Robert Baines,Pulickel M. Ajayan,Mingxin Ye,Jianfeng Shen +6 more
TL;DR: The pilot study of a controllable method for the preparation of a series of NiX2 (X = S, Se, Te) nanosheets via a facile anion-exchange reaction found the results from electrochemical measurements were found to be fully consistent with the data based on density function theory calculation.
Journal ArticleDOI
Electrical transport and field-effect transistors using inkjet-printed SWCNT films having different functional side groups.

TL;DR: The electrical properties of random networks of single-wall carbon nanotubes obtained by inkjet printing are studied and the positive temperature coefficient of channel resistance shows the nonmetallic behavior of the inkjet-printed films.
