Super-stretchable, Transparent Carbon Nanotube-Based Capacitive Strain Sensors for Human Motion Detection
Le Cai,Li Song,Pingshan Luan,Qiang Zhang,Nan Zhang,Qingqing Gao,Duan Zhao,Xiao Zhang,Min Tu,Feng Yang,Wenbin Zhou,Qingxia Fan,Jun Luo,Weiya Zhou,Pulickel M. Ajayan,Sishen Xie,Sishen Xie +16 more
TL;DR: The designed stretchable multifunctional CNT-based strain gauge may have various potential applications in human friendly and wearable smart electronics, subsequently demonstrated by the prototypical data glove and respiration monitor.
Journal ArticleDOI
Ultrathin high-temperature oxidation-resistant coatings of hexagonal boron nitride.
Zheng Liu,Yongji Gong,Wu Zhou,Wu Zhou,Lulu Ma,Jingjiang Yu,Juan Carlos Idrobo,Jeil Jung,Jeil Jung,Allan H. MacDonald,Robert Vajtai,Jun Lou,Pulickel M. Ajayan +12 more
TL;DR: These hexagonal boron nitride atomic layer coatings, which can be synthesized via scalable chemical vapour deposition method down to only two layers, could be the thinnest coating ever shown to withstand such extreme environments and find applications as chemically stable high-temperature coatings.
Journal ArticleDOI
Evolution of the Electronic Band Structure and Efficient Photo-Detection in Atomic Layers of InSe
Sidong Lei,Liehui Ge,Sina Najmaei,Antony George,Rajesh Kappera,Jun Lou,Manish Chhowalla,Hisato Yamaguchi,Gautam Gupta,Robert Vajtai,Aditya D. Mohite,Pulickel M. Ajayan +11 more
TL;DR: Correlation between resonance Raman spectroscopy and photoconductivity measurements allows us to systematically track the evolution of the electronic band structure of 2D InSe as its thickness approaches few atomic layers.
Journal ArticleDOI
Selective Attachment of Gold Nanoparticles to Nitrogen-Doped Carbon Nanotubes
Kuiyang Jiang,A. Eitan,Linda S. Schadler,Pulickel M. Ajayan,Richard W. Siegel,Nicole Grobert,Martine Mayne,Marisol Reyes-Reyes,Humberto Terrones,Mauricio Terrones +9 more
TL;DR: Gold nanoparticles were selectively attached to chemically functionalized surface sites on nitrogen-doped carbon (CNx) nanotubes by electrostatic interaction between carboxyl groups on the chemically oxidized nanotube surface and polyelectrolyte chains as discussed by the authors.
Journal ArticleDOI
Light-induced lattice expansion leads to high-efficiency perovskite solar cells
Hsinhan Tsai,Hsinhan Tsai,Reza Asadpour,Jean-Christophe Blancon,Constantinos C. Stoumpos,Olivier Durand,Joseph Strzalka,Bo Chen,Rafael Verduzco,Pulickel M. Ajayan,Sergei Tretiak,Jacky Even,Muhammad Ashraf Alam,Mercouri G. Kanatzidis,Wanyi Nie,Aditya D. Mohite,Aditya D. Mohite +16 more
TL;DR: Correlated, in situ structural and device characterizations reveal that light-induced lattice expansion benefits the performances of a mixed-cation pure-halide planar device, boosting the power conversion efficiency from 18.5 to 20.5%.
