  • Dynamic Self-Stiffening in Liquid Crystal Elastomers 

    Agrawal, Aditya; Chipara, Alin C.; Shamoo, Yousif; Patra, Prabir K.; Carey, Brent J.; Ajayan, Pulickel M.; Chapman, Walter G.; Verduzco, Rafael (2013)
    Biological tissues have the remarkable ability to remodel and repair in response to disease, injury and mechanical stresses. Synthetic materials lack the complexity of biological tissues, and man-made materials that respond ...
  • Efficient Modulation of 1.55 μm Radiation with Gated Graphene on a Silicon Microring Resonator 

    Qiu, Ciyuan; Gao, Weilu; Vajtai, Robert; Ajayan, Pulickel M.; Kono, Junichiro; Xu, Qianfan (2014)
    The gate-controllability of the Fermi-edge onset of interband absorption in graphene can be utilized to modulate near-infrared radiation in the telecommunication band. However, a high modulation efficiency has not been ...
  • Electrically tunable hot-silicon terahertz attenuator 

    Wang, Minjie; Vajtai, Robert; Ajayan, Pulickel M.; Kono, Junichiro (2014)
    We have developed a continuously tunable, broadband terahertz attenuator with a transmission tuning range greater than 103. Attenuation tuning is achieved electrically, by simply changing the DC voltage applied to a heating ...
  • Paintable Battery 

    Singh, Neelam; Galande, Charudatta; Miranda, Andrea; Mathkar, Akshay; Gao, Wei; Reddy, Arava Leela Mohana; Vlad, Alexandru; Ajayan, Pulickel M. (2012-06-28)
    If the components of a battery, including electrodes, separator, electrolyte and the current collectors can be designed as paints and applied sequentially to build a complete battery, on any arbitrary surface, it would ...
  • Vertical and in-plane heterostructures from WS2/MoS2 monolayers 

    Gong, Yongji; Lin, Junhao; Wang, Xingli; Shi, Gang; Lei, Sidong; Lin, Zhong; Zou, Xiaolong; Ye, Gonglan; Vajtai, Robert; Yakobson, Boris I.; Terrones, Humberto; Terrones, Mauricio; Tay, Beng Kang; Lou, Jun; Pantelides, Sokrates T.; Liu, Zheng; Zhou, Wu; Ajayan, Pulickel M. (2014)
    Layer-by-layer stacking or lateral interfacing of atomic monolayers has opened up unprecedented opportunities to engineer two-dimensional heteromaterials. Fabrication of such artificial heterostructures with atomically ...
