  • two ply yarn supercapacitor based on carbon nanotube stainless Steel Core sheath yarn electrodes and ionic liquid electrolyte
    Journal of Power Sources, 2016
    Co-Authors: Xiaoming Lyu, Menghe Miao
    Abstract:

    Abstract Linear supercapacitors have great potential as power source in electronic textiles. However, the energy density of most yarn supercapacitors reported so far is still quite low and decreases significantly as the supercapacitor length increases. Here, we report a two-ply yarn supercapacitor based on carbon nanotube/stainless Steel Core-sheath yarn electrode and ionic liquid electrolyte. The use of IL gel electrolyte widens the potential window of supercapacitor from 1.0 V to 2.7 V. The carbon nanotube/stainless Steel Core-sheath yarn structure greatly improves the charge transport efficiency and allows the length of the linear supercapacitor to be significantly scaled up. The resulting supercapacitor has shown outstanding electrochemical performances with a high volumetric capacitance of 263.31 F cm −3 and energy density of 6.67×10 −2  Wh cm −3 . The two-ply yarn supercapacitors are also very flexible and strong for use as sewing thread and for making knots without significant loss of their energy storage capacity.

  • modeling thermo mechanical behavior of concrete filled Steel tube columns with solid Steel Core subjected to fire
    Engineering Structures, 2017
    Co-Authors: Martin Neuenschwander, Markus Knobloch, Mario Fontana
    Abstract:

    Abstract Concrete-filled Steel tube columns with solid Steel Core are increasingly used in high-rise building practice due to their high load-bearing capacity and exceptional structural fire behavior. Simulating the structural fire behavior of these innovative composite columns by means of advanced numerical models is a promising tool to achieve an enhanced understanding of the basic thermo-mechanical behavior observed in costly full-scale fire tests, and eventually, to partially replace them. Moreover, the data necessary for the development of a simplified fire design method can be compiled from a parametric study with such models. This paper presents an advanced nonlinear Finite-Element-Method model that incorporates complex experimental calibration data and therefore can robustly simulate various full-scale fire tests of this type of composite columns. Furthermore, tracking in the model the load share redistribution processes between the different components, confirms the innovative design concept of the structural fire behavior of this type of composite column. Finally, a simplified model version that qualifies for partial replacement of full-scale fire tests or use in both a parametric study and advanced structural design is presented and conditionally validated.

  • fire behavior of concrete filled circular hollow section columns with massive Steel Core
    2010
    Co-Authors: Martin Neuenschwander, Markus Knobloch, Mario Fontana
    Abstract:

    The paper analyses the structural fire behavior of centrically loaded concrete-filled Steel CHS with a massive Steel Core. A numerical model for a geometrically and temperature-dependent materially nonlinear analysis of the imperfect structure is presented. A comprehensive numerical study shows the influence of the thermal expansion as well as the bonding behavior between Steel and concrete on the structural fire behavior.

  • Coupling current control in stabrite-coated NbTi Rutherford cables by varying the width of a stainless Steel Core
    Advances in cryogenic engineering, 2000
    Co-Authors: M.d. Sumption, E. W. Collings, Arend Nijhuis, R.m. Scanlan
    Abstract:

    AC loss measurements were made on a series of Rutherford cables wound from stabrite-coated NbTi/Cu multifilamentary strand, from the results of which interstrand contact resistances were calculated. The 28-strand, 15 mm wide, LHC-inner type cables contained stainless Steel Cores of widths varying from 0 (no Core) to 12.7 mm. Measurements were made on 4-layer cable packs. Two main preparation (curing) cycles were used: (1) heat treatment (HT) at 170°C under 80 MPa followed by pressure release and re-application before measurement; (2) HT to 200°C and maintenance of the pressure until after measurement. One additional protocol-(1)-treated pack was prepared from cables that had received a diffusion HT of 200°C/8h in air following a CERN-recommended prescription for achieving a satisfactory contact resistance (ICR). Calorimetric loss measurements were made on all samples using a sinusoidal field with an amplitude of 400 mT. It is concluded that by adjusting the width of a stainless Steel Core the effective ICR, R⊥ ,eff , of a stabrite-coated LHC-inner-type Rutherford cable can be varied over a wide range, and in particular that a published target of 15 μΩ could be attained with a Core width of 8.5 mm - a little more than one-half the width of the cable, leaving the rest of the cable free for current sharing. It is also concluded that in terms of R⊥ ,eff the OSU-administered CERN diffusion HT was equivalent to inserting a 9.5-mm-wide Core.
