    • Creep and Inverse Stress Relaxation Behaviors of Carbon Nanotube Yarns 

      Misak, Heath Edward; Sabelkin, V.; Miller, L.; Asmatulu, Ramazan; Mall, Shankar (American Scientific Publishers, 2013-12)
      Creep, creep recovery and inverse stress relaxation behaviors of carbon nanotube yarns that consisted of 1-, 30-, and 100-yarn(s) were characterized. Primary and secondary creep stages were observed over the duration of ...
    • Electrical conductivity, strength and microstructure of carbon nanotube multi-yarns 

      Misak, Heath Edward; Mall, Shankar (Elsevier Ltd., 2015-06-15)
      Since the inception of carbon nanotubes (CNTs), there has been a great deal of effort in developing CNT applications. One possible application is to utilize CNT yarn(s) in structural and electrical devices. This study ...
    • Failure analysis of carbon nanotube wires 

      Misak, Heath Edward; Sabelkin, V.; Mall, Shankar; Asmatulu, Ramazan; Kladitis, P.E. (Elsevier, 2012-06-15)
      A failure analysis of four carbon nanotube (CNT) wires comprised of 1-, 30-, 60-, and 100-yarns was conducted when subjected to constant tension and cyclic tension-tension loading conditions. Each wire had different ...
    • High-temperature cross-linking of carbon nanotube multi-yarn using polyvinylpyrrolidone as a binding agent 

      Misak, Heath Edward; Asmatulu, Ramazan; Whitman, J.; Mall, Shankar (American Scientific Publishers, 2015-03)
      Carbon nanotube (CNT) multi-yarn was cross-linked together at elevated temperatures using a polymer, with the intent of improving their strength and electrical conductivity. They were functionalized using an acid treatment ...
    • Investigation into microstructure of carbon nanotube multi-yarn 

      Misak, Heath Edward; Mall, Shankar (Elsevier, 2014-02-08)
      Structural analysis at the nano and micro scale was performed on a carbon nanotube (CNT) multi-yarn. The yarns were made by a process of drawing CNTs into a ribbon and twisting the ribbon into a yarn. Scanning electron ...
    • Tensile behavior of carbon nanotube multi-yarn coated with polyester 

      Asmatulu, Ramazan; Mall, Shankar; Misak, Heath Edward (2014-06-13)
      The behavior of a carbon nanotube (CNT) multi-yarn consisting of 30 yarns and coated with a thin layer of polyester is investigated under tensile loading condition. The coated and uncoated CNT multi-yarns are loaded until ...

      Misak, Heath Edward; Asmatulu, Ramazan; Mall, Shankar (SAGE Publications, 2015-06)
      The behavior of a carbon nanotube (CNT) multi-yarn consisting of 30 yarns and coated with a thin layer of polyester is investigated under tensile loading condition. The coated and uncoated CNT multi-yarns are loaded until ...
    • Tensile loading behavior of carbon nanotube wires 

      Sabelkin, V.; Misak, Heath Edward; Mall, Shankar; Asmatulu, Ramazan; Kladitis, P.E. (Elsevier, 2012-02-08)
      The mechanical behavior of four carbon nanotube (CNT) wires, comprised of 1-yarn, 30-yarn, 60-yarn, and 100-yarn, was investigated under constant tension at two loading rates of 0.02 mm/sec and 2 mm/sec. Tests were conducted ...
    • Tension-tension fatigue behavior of carbon nanotube wires 

      Misak, Heath Edward; Asmatulu, Ramazan; Sabelkin, V.; Mall, Shankar; Kladitis, P.E. (Elsevier, 2012-09-23)
      The tension-tension fatigue behavior of three types of as-received carbon nanotube (CNT) wires, comprising of 30-yarn, 60-yarn, and 100-yarn, was investigated. Fatigue tests were conducted at 35, 50, 60, 75 and 80% of their ...
    • Time-dependent electrical properties of carbon nanotube yarns 

      Misak, Heath Edward; Mall, Shankar (Elsevier B.V., 2015-06)
      Carbon nanotubes (CNTs) are projected as a desirable option to transmit electrical power where specific conductivity. is an important consideration. A CNT-yarn was therefore characterized for its ability to transmit power ...
