Journal ArticleDOI
Functionalization of carbon nanotubes using phenosafranin.
TL;DR: Spectroscopic analysis and atomic force microscopy phase imaging studies show self-assembly of phenosafranin to multiwalled carbon nanotubes (MWNTs) and the shift in absorption spectra is associated with charge transfer of valence electrons from PSF to electron accepting sites on the MWNTs.
Journal ArticleDOI
Interphase Induced Dynamic Self-Stiffening in Graphene-Based Polydimethylsiloxane Nanocomposites.
Linlin Cao,Yanlei Wang,Pei Dong,Soumya Vinod,Jaime Taha Tijerina,Pulickel M. Ajayan,Zhi Ping Xu,Jun Lou +7 more
TL;DR: Graphene-based polydimethylsiloxane (PDMS) nanocomposite, a chemically and physically cross-linked system, exhibits an increase in the storage modulus under low-frequency, low-amplitude dynamic compressive loading.
Journal ArticleDOI
Ambient solid-state mechano-chemical reactions between functionalized carbon nanotubes
Mohamad A. Kabbani,Chandra Sekhar Tiwary,Pedro Alves da Silva Autreto,Gustavo Brunetto,Anirban Som,K. R. Krishnadas,Sehmus Ozden,Ken Hackenberg,Yongi Gong,Douglas S. Galvao,Robert Vajtai,Ahmad T. Kabbani,Thalappil Pradeep,Pulickel M. Ajayan +13 more
TL;DR: An ambient mechano-chemical reaction between two varieties of nanotubes, carrying predominantly carboxyl and hydroxyl functionalities, respectively, facilitated by simple mechanical grinding of the reactants is reported.
Journal ArticleDOI
3D Band Diagram and Photoexcitation of 2D–3D Semiconductor Heterojunctions
Bo Li,Gang Shi,Sidong Lei,Yongmin He,Weilu Gao,Yongji Gong,Gonglan Ye,Wu Zhou,Kunttal Keyshar,Ji Hao,Pei Dong,Liehui Ge,Jun Lou,Junichiro Kono,Robert Vajtai,Pulickel M. Ajayan +15 more
TL;DR: A new 3D band diagram is proposed for the heterojunction formed between n-type monolayer MoS2 and p-type Si, in which the conduction and valence band-edges of theMoS2 monolayers are drawn for both stacked and in-plane directions.
Journal ArticleDOI
Temperature dependent Raman and photoluminescence of vertical WS2/MoS2 monolayer heterostructures
Zhijian Hu,Yanjun Bao,Ziwei Li,Yongji Gong,Rui Feng,Yingdong Xiao,Xiaochun Wu,Zhaohui Zhang,Xing Zhu,Pulickel M. Ajayan,Zheyu Fang +10 more
TL;DR: In this paper, the temperature dependent Raman and photoluminescence spectra in vertical stacked WS2/MoS2 monolayer heterostructures were investigated.
