Journal ArticleDOI
Material science: oxygen breaks into carbon world.
TL;DR: When oxygen atoms bind to a graphite surface, they fall into line and make bridges across carbon atoms, and this is the spearhead of a chemical attack in which the atomic arrangement of solid carbon is torn apart.
Journal ArticleDOI
Strong coupling and pressure engineering in WSe 2 –MoSe 2 heterobilayers
Juan Xia,Juan Xia,Jiaxu Yan,Jiaxu Yan,Zenghui Wang,Yongmin He,Yongji Gong,Weiqiang Chen,Weiqiang Chen,Tze Chien Sum,Zheng Liu,Pulickel M. Ajayan,Zexiang Shen +12 more
TL;DR: In this paper, a two-step chemical vapour deposition method was used to realize high-quality 2H-stacked WSe2-MoSe2 heterostructures with strong interlayer coupling, and effective tuning of their interlayer interaction by hydrostatic pressure.
Journal ArticleDOI
Functionalized low defect graphene nanoribbons and polyurethane composite film for improved gas barrier and mechanical performances.

TL;DR: A thermoplastic polyurethane (TPU) composite film containing hexadecyl-functionalized low-defect graphene nanoribbons (HD-GNRs) was produced by solution casting and improved the mechanical properties of the composite films, as predicted by the phase separation and indicated by tensile tests and dynamic mechanical analyses.
Journal ArticleDOI
Photoinduced oxidation of carbon nanotubes
T. Savage,Sriparna Bhattacharya,B. Sadanadan,Jay Gaillard,Terry M. Tritt,Ya-Ping Sun,Yudong Wu,Saroj K. Nayak,Roberto Car,Nicola Marzari,Pulickel M. Ajayan,Apparao M. Rao +11 more
TL;DR: In this article, photo-induced molecular desorption of oxygen has been reported in carbon nanotubes using thermopower measurements, and two plausible mechanisms for the experimentally observed photoinduced oxidation are proposed: (i) a lower energy barrier for photo-generated singlet oxygen, or (ii) due to the presence of defects in carbon Nanotubes.
Journal ArticleDOI
Magnetism in two-dimensional materials beyond graphene
N. Sethulakshmi,Avanish Mishra,Pulickel M. Ajayan,Yoshiyuki Kawazoe,Ajit K. Roy,Abhishek K. Singh,Chandra Sekhar Tiwary,Chandra Sekhar Tiwary,Chandra Sekhar Tiwary +8 more
TL;DR: In this paper, the authors provide an overview of low-dimensional magnetism in graphene, h-BN, and carbon nitrides, which originates from defects like vacancy, adatom, doping, and dangling bonds.
