Electrochromic supercapacitors may alert the user on the remaining capacity of the devices. The color change indicating the remaining capacity can be simply and rapidly recognized by the human eye or by optical instruments. A rapid indication of charged state may extend device service life and prevent overcharging, which would otherwise result in electrode aging and decomposition. In this study, a blue to the transmissive electrochromic polymer, poly(4,7-bis(2,3-dihydrothieno[3,4-B][1,4]dioxin-5-YI)-2-(2-octyldodecyl)-2H-benzo[D][1,2,3]triazole) (P1C), was used in nanocomposite form with transparent silver nanowire (Ag NW) network current collectors for the fabrication of electrochromic supercapacitor electrodes. Highly conductive and transparent Ag NW networks have an important role in the realization of electrochromic supercapacitors using P1C. Fabricated Ag NW/P1C nanocomposite electrodes had a specific capacitance of 65.0Fg(-1) at a current density of 0.1Ag(-1). Nanocomposite electrode showed excellent stability (capacity retention of>98%) after 11000cycles associated with a resistance decrease associated with charge transfer.

Silver nanowire inks for fabrics Güven, Merve Nur; Toppare, Levent Kamil; Department of Chemistry (2019) Conductive inks are used extensively in electronic devices like sensors, batteries, photovoltaic devices, antenna and organic light emitting diodes. These inks typically made from silver. Wearable technology is another industry which requires inks to be flexible. These devices need low temperature cured silver pastes. Low temperature pastes typically make use of silver nanoparticles. These pastes have some problems with sintering and substrate adhesion. In this thesis, to overcome these problems, silver nan...
A phase-field model for chemo-mechanical induced fracture in lithium-ion battery electrode particles MIEHE, C.; Dal, Hüsnü; SCHAENZEL, L. -M.; RAINA, A. (2016-06-01) Capacity fade in conventional Li-ion battery systems due to chemo-mechanical degradation during charge-discharge cycles is the bottleneck in high-performance battery design. Stresses generated by diffusion-mechanical coupling in Li-ion intercalation and deintercalation cycles, accompanied by swelling and shrinking at finite strains, cause micro-cracks, which finally disturb the electrical conductivity and isolate the electrode particles. This leads to battery capacity fade. As a first attempt towards a reli...
A Flexible semantic service composition framework for pervasive computing environments Özpınar, Mustafa; Eren, Pekin Erhan; Department of Information Systems (2014) With the advances in technology, high-speed connections, powerful and low cost devices have become available. İt is estimated that there will be tens of billions of devices connected to the İnternet by 2020. However, for the effective use of such an outstanding number of devices, they should be able to communicate with each other in different scenarios. A commonly agreed structure should be adopted to overcome the communication problem of heterogeneous devices. Web of Things (WoT) is a vision about quickly ...
Production and characterization of nano silver oxide for silver zinc batteries Yurtseven, Özüm Öyküm; Aydınol, Mehmet Kadri; Nalbant Esentürk, Emren; Department of Micro and Nanotechnology (2013) Rechargeable silver-zinc batteries have aroused interest and find various area of usage depending on their notably technical advantages over other battery systems including their high specific energy and high recharge efficiency. In this battery chemistry, silver oxide and metallic zinc are used as the positive and negative active materials respectively. Chemically stabilized particles with large surface areas are needed to reach high discharge rates for battery applications. The use of nanoparticles as ele...
Carbon Nanotube-Based Nanoscale Ad Hoc Networks Atakan, Baris; Akan, Ozgur B. (2010-06-01) Recent developments in nanoscale electronics allow current wireless technologies to function in nanoscale environments. Especially due to their incredible electrical and electromagnetic properties, carbon nanotubes are promising physical phenomenon that are used for the realization of a nanoscale communication paradigm. This provides a very large set of new promising applications such as collaborative disease detection with communicating in-vivo nanosensor nodes and distributed chemical attack detection wit...
