    • Bio-Inspired, Moisture-Powered Hybrid Carbon Nanotube Yarn Muscles 

      Kim, Shi Hyeong; Kwon, Cheong Hoon; Park, Karam; Mun, Tae Jin; Lepro, Xavier; Baughman, Ray H.; Spinks, Geoffrey M.; Kim, Seon Jeong
      Hygromorph artificial muscles are attractive as self-powered actuators driven by moisture from the ambient environment. Previously reported hygromorph muscles have been largely limited to bending or torsional motions or ...
    • Biothermal Sensing of a Torsional Artificial Muscle 

      Lee, Sung-Ho; Kim, Tae Hyeob; Lima, M©rcio D.; Baughman, Ray H.; Kim, Seon Jeong (Royal Soc Chemistry, 2016-01-25)
      Biomolecule responsive materials have been studied intensively for use in biomedical applications as smart systems because of their unique property of responding to specific biomolecules under mild conditions. However, ...
    • Conductive Functional Biscrolled Polymer and Carbon Nanotube Yarns 

      Kim, S. H.; Sim, H. J.; Shin, M. K.; Choi, A. Y.; Kim, Y. T.; Lima, Marcio D.; Baughman, Ray H.; Kim, S. J. (2013-10-10)
      Biscrolling aligned electrospun fiber (AEF) sheets and carbon nanotube (CNT) sheets were fabricated for conductive, functional yarns by a versatile dry composite method. Our biscrolling (twist-based spinning) method is ...
    • High-Performance Biscrolled MXene/Carbon Nanotube Yarn Supercapacitors 

      Wang, Z.; Qin, S.; Seyedin, S.; Zhang, J.; Wang, J.; Levitt, A.; Li, Na; Haines, Carter; Ovalle-Robles, R.; Lei, W.; Gogotsi, Y.; Baughman, Ray H.; Razal, J. M.
      Yarn-shaped supercapacitors (YSCs) once integrated into fabrics provide promising energy storage solutions to the increasing demand of wearable and portable electronics. In such device format, however, it is a challenge ...
    • A New Catalyst-Embedded Hierarchical Air Electrode For High-Performance Li-O₂ Batteries 

      Lim, H. -D; Song, H.; Gwon, H.; Park, K. -Y; Kim, J.; Bae, Y.; Kim, H.; Jung, S. -K; Kim, T.; Kim, Y. H.; Lepr©, Xavier; Ovalle-Robles, Raquel; Baughman, Ray H.; Kang, K. (2013-06-05)
      The Li-O₂ battery holds great promise as an ultra-high-energy- density device. However, its limited rechargeability and low energy efficiency remain key barriers to its practical application. Herein, we demonstrate that ...
    • Preparation and Characterization of Hybrid Conducting Polymer–Carbon Nanotube Yarn 

      Foroughi, Javad; Spinks, Geoffrey M.; Ghorbani, Shaban R.; Kozlov, Mikhail E.; Safaei, Farzad; Peleckis, Germanas; Wallace, Gordon G.; Baughman, Ray H. (2011-12-16)
      Hybrid polypyrrole (PPy)-multi walled carbon nanotube(MWNT) yarns were obtained by chemical and electrochemical polymerization of pyrrole on the surface and within the porous interior of twisted MWNT yarns. The material ...
    • Regulation of Morphogenesis and Neural Differentiation of Human Mesenchymal Stem Cells Using Carbon Nanotube Sheets 

      Kim, Jeong Ah; Jang, Eui Yun; Kang, Tae June; Yoon, Sungjun; Ovalle-Robles, Raquel; Rhee, Won Jong; Kim, Taewoo; Baughman, Ray H.; Kim, Yong Hyup; Park, Tai Hyun (2012-04-02)
      In order to successfully utilize stem cells for therapeutic applications in regenerative medicine, efficient differentiation into a specific cell lineage and guidance of axons in a desired direction is crucial. Here, we ...
    • Terahertz Surface Plasmon Polaritons on Freestanding Multi-Walled Carbon Nanotube Aerogel Sheets 

      Nguyen, T. D.; Liu, S.; Lima, Marcio Dias; Fang, Shaoli; Baughman, Ray H.; Nahata, A.; Vardeny, Z. V. (2012-05-08)
      We demonstrate that multi-walled carbon nanotubes (MWCNTs) are capable of supporting surface plasmon-polaritons (SPPs) at terahertz (THz) frequencies. To achieve this, we fabricated sub-100 μm-thick freestanding and highly ...
