    • Atomic cobalt on nitrogen-doped graphene for hydrogen generation 

      Fei, Huilong; Dong, Juncai; Arellano-Jiménez, M. Josefina; Ye, Gonglan; Kim, Nam Dong; Samuel, Errol L.G.; Peng, Zhiwei; Zhu, Zhuan; Qin, Fan; Bao, Jiming; Yacaman, Miguel Jose; Ajayan, Pulickel M.; Chen, Dongliang; Tour, James M. (2015)
      Reduction of water to hydrogen through electrocatalysis holds great promise for clean energy, but its large-scale application relies on the development of inexpensive and efficient catalysts to replace precious platinum ...
    • Blueshift of the A-exciton peak in folded monolayer 1H-MoS2 

      Crowne, Frank J.; Amani, Matin; Birdwell, A. Glen; Chin, Matthew L.; OメRegan, Terrance P.; Najmaei, Sina; Liu, Zheng; Ajayan, Pulickel M.; Lou, Jun; Dubey, Madan (2013)
    • CVD-grown monolayered MoS2 as an effective photosensor operating at low-voltage 

      Perea-López, Néstor; Lin, Zhong; Pradhan, Nihar R.; Iñiguez-Rábago, Agustín; Elías, Ana Laura; McCreary, Amber; Lou, Jun; Ajayan, Pulickel M.; Terrones, Humberto; Balicas, Luis; Terrones, Mauricio (2014)
      We report the fabrication of a photosensor based on as-grown single crystal monolayers of MoS2synthesized by chemical vapor deposition (CVD). The measurements were performed using Au/Ti leads in a two terminal configuration ...
    • Roll up nanowire battery from silicon chips 

      Vlad, Alexandru; Reddy, Arava Leela Mohana; Ajayan, Anakha; Singh, Neelam; Gohy, Jean-François; Melinte, Sorin; Ajayan, Pulickel M. (2012)
      Here we report an approach to roll out Li-ion battery components from silicon chips by a continuous and repeatable etch-infiltratepeel cycle. Vertically aligned silicon nanowires etched from recycled silicon wafers are ...
    • Second harmonic microscopy of monolayer MoS2 

      Kumar, Nardeep; Najmaei, Sina; Cui, Qiannan; Ceballos, Frank; Ajayan, Pulickel M.; Lou, Jun; Zhao, Hui (2013)
      We show that the lack of inversion symmetry in monolayer MoS2 allows strong optical second harmonic generation. The second harmonic of an 810-nm pulse is generated in a mechanically exfoliated monolayer, with a nonlinear ...
    • Super-stretchable, Transparent Carbon Nanotube-Based Capacitive Strain Sensors for Human Motion Detection 

      Cai, Le; Song, Li; Luan, Pingshan; Zhang, Qiang; Zhang, Nan; Gao, Qingqing; Zhao, Duan; Zhang, Xiao; Tu, Min; Yang, Feng; Zhou, Wenbin; Fan, Qingxia; Luo, Jun; Zhou, Weiya; Ajayan, Pulickel M.; Xie, Sishen (2013)
      Realization of advanced bio-interactive electronic devices requires mechanically compliant sensors with the ability to detect extremely large strain. Here, we design a new multifunctional carbon nanotube (CNT) based capacitive ...
