We present a novel one-dimensional coaxial architecture composed of silver nanowire (Ag NW) network core and nickel hydroxide (Ni(OH)(2)) shell for the realization of coaxial nanocomposite electrode materials for supercapacitors. Ag NWs are formed conductive networks via spray coating onto polyethylene terephthalate (PET) substrates and Ni(OH)(2) is gradually electrodeposited onto the Ag NW network to fabricate core-shell electrodes for supercapacitors. Synergy of highly conductive Ag NWs and high capacitive Ni(OH)(2) facilitate ion and electron transport, enhance electrochemical properties and result in a specific capacitance of 1165.2 F g(-1) at a current density of 3 A g(-1). After 3000 cycles, fabricated nanocomposite electrodes show 93% capacity retention. The rational design explored in this study points out the potential of nanowire based coaxial energy storage devices.

Coaxial silver nanowire/polypyrrole nanocomposite supercapacitors
YÜKSEL, Recep; ALPUGAN, Ece; Ünalan, Hüsnü Emrah (2018-01-01)
Three-dimensional (3D) core-shell silver nanowire (Ag NW) -polypyrrole (PPy) nanocomposites are used for the fabrication of supercapacitors. In-situ chemical polymerization of PPy onto Ag NWs results in the formation of diameter tunable, coaxial and 3D nanocomposites. Inner Ag NW core facilitates the charge transfer and PPy shell shows a remarkably high pseudocapacitance. Fabricated Ag NW/PPy nanocomposite has a specific capacitance of 509 F g(-1) at a current density of 0.31 A g(-1), while the energy and p...
Coaxial silver nanowire network core molybdenum oxide shell supercapacitor electrodes
Yuksel, Recep; Coskun, Sahin; Ünalan, Hüsnü Emrah (Elsevier BV, 2016-03-01)
We present a new hybrid material composed of molybdenum (IV) oxide (MoO2) shell on highly conducting silver nanowire (Ag NW) core in the network form for the realization of coaxial Ag NW/MoO2 nanocomposite supercapacitor electrodes. Ag NWs were simply spray coated onto glass substrates to form conductive networks and conformal MoO2 layer was electrodeposited onto the Ag NW network to create binder-free coaxial supercapacitor electrodes. Combination of Ag NWs and pseudocapacitive MoO2 generated an enhanced e...
Optimized spacer layer thickness for plasmonic-induced enhancement of photocurrent in a-Si:H
Saleh, Z. M.; NASSER, H; ÖZKOL, E; GÜNÖVEN, M; Abak, Musa Kurtuluş; Canlı, Sedat; Bek, Alpan; Turan, Raşit (2015-10-24)
Plasmonic interfaces consisting of silver nanoparticles of different sizes (50-100 nm) have been processed by the self-assembled dewetting technique and integrated to hydrogenated amorphous silicon (a-Si:H) using SiNx spacer layers to investigate the dependence of optical trapping enhancement on spacer layer thickness through the enhancements in photocurrent. Samples illuminated from the a-Si:H side exhibit a localized surface plasmon resonance (LSPR) that is red-shifted with the increasing particle size an...
Wearable supercapacitors based on nickel tungstate decorated commercial cotton fabrics
Hekmat, Farzaneh; Tutel, Yusuf; Ünalan, Hüsnü Emrah (2020-07-01)
Symmetric supercapacitors (SSCs) with remarkable energy storing capability, high specific power as well as long-term cyclic stability were fabricated from nickel tungstate (NiWO4) @ nickel oxide (NiOx) decorated commercial cotton fabrics (CCFs). A commercial cotton-based textile was first made conductive by the state of the art ultrasonic spray coating method. This was followed by chemical and electrochemical processes to decorate activated CCFs with NiO(x)and NiWO4, respectively. The assembled SSCs had the...
Fabrication of SiO2-stacked diamond membranes and their characteristics for microelectromechanical applications
Bayram, Barış (Elsevier BV, 2011-04-01)
Diamond is a promising microelectromechanical systems (MEMS) material due to its high Young's Modulus and very large thermal conductivity. In this work, ultrananocrystalline diamond was stacked between silicon dioxide to form thermally-stable and robust membranes. These SiO2-stacked diamond layers were processed into MEMS-compatible membranes. For comparison, membranes composed of only SiO2 were fabricated as well. The structural characteristics of these membranes are compared and analyzed for membranes of ...
