Journal ArticleDOI
Heterodoped Nanotubes: Theory, Synthesis, and Characterization of Phosphorus−Nitrogen Doped Multiwalled Carbon Nanotubes
Eduardo Cruz-Silva,David A. Cullen,Lin Gu,José M. Romo-Herrera,Emilio Muñoz-Sandoval,Florentino López-Urías,Bobby G. Sumpter,Vincent Meunier,Jean-Christophe Charlier,David J. Smith,Humberto Terrones,Mauricio Terrones +11 more
TL;DR: It is demonstrated that iron phosphide (Fe(3)P) nanoparticles act as catalysts during nanotube growth, leading to the formation of novel PN-doped multiwalled carbon nanotubes, predicted to offer many new opportunities in the fabrication of fast-response chemical sensors.
Journal ArticleDOI
Low-Frequency Shear and Layer-Breathing Modes in Raman Scattering of Two-Dimensional Materials.
TL;DR: A comprehensive and forward-looking review on the current status of exploiting LF Raman modes of 2DMs from both experimental and theoretical perspectives is presented, revealing the fundamental physics and technological significance of LFRaman modes in advancing the field of 2 DMs.
Journal ArticleDOI
Transition-Metal Substitution Doping in Synthetic Atomically Thin Semiconductors.
Jian Gao,Young Duck Kim,Liangbo Liang,Liangbo Liang,Juan Carlos Idrobo,Phil Chow,Jiawei Tan,Baichang Li,Lu Li,Bobby G. Sumpter,Toh-Ming Lu,Vincent Meunier,James Hone,Nikhil Koratkar +13 more
TL;DR: Large-area "in situ" transition-metal substitution doping for chemical-vapor-deposited semiconducting transition- metal-dichalcogenide monolayers deposited on dielectric substrates is demonstrated.
Journal ArticleDOI
Complex Capacitance Scaling in Ionic Liquids-Filled Nanopores
TL;DR: A theoretical framework for understanding the capacitance of electrical double layers in nanopores is established and mechanistic details into the origins of the observed scaling behavior are provided, highlighting the critical role of "ion solvation" in controlling pore capacitance and the importance of choosing anion/cation couples carefully for optimal energy storage in a given pore system.
Journal ArticleDOI
Dynamics of fluid flow inside carbon nanotubes
TL;DR: The dynamics of fluid flow through nanomachines is different from in other systems in that the flow is granular (no continuum assumption) and that the ''walls' move as mentioned in this paper.
