Using poly(3,4-ethylenedioxythiophene)-poly (styrene sulfonate) (PEDOT-PSS) as the transparent electrode material, all-polymer-based electrochromic devices (ECDs) have been constructed from only organic and polymeric components. In the picture shown, an absorption/transmissive-type ECD maintained in its colored state is bent to demonstrate its flexibility.

The Use of Terahertz Spectroscopy as a Sensitive Probe in Discriminating the Electronic Properties of Structurally Similar Multi-Walled Carbon Nanotubes Parrott, Edward P. J.; Zeitler, J. Axel; McGregor, James; Oei, Shu-Pei; Ünalan, Hüsnü Emrah; Milne, William I.; Tessonnier, Jean-Philippe; Su, Dong Sheng; Schloegl, Robert; Gladden, Lynn F. (2009-10-19) Terahertz: spectroscopy is used to definitively distinguish between two multi-walled carbon nanotubes (see figure), which have commercial applications in a number of advanced materials. Other techniques do not provide a sensitive discrimination of the measured properties. This observation is rationalized by considering the dielectric nature of the materials and the relationship of this to their structural differences.
First-principles investigation of CO and CO2 adsorption on gamma-Al2O3 supported monoatomic and diatomic Pt clusters Sensoy, Mehmet Gokhan; Toffoli, Hande; Toffolı, Danıele (Elsevier BV, 2020-01-01) Supported clusters of transition metal atoms are key components of heterogeneous catalysts. Understanding their interaction with small molecular species is therefore an important step in catalyst design. In this work, we provide a detailed first-principles investigation of the adsorption properties of CO and CO2 on Pt-n (n = 1, 2) clusters supported by a gamma-Al2O3 (1 0 0) substrate. In particular, important parameters such as the stability of the Pt clusters, molecular adsorption energies and vibration fr...
The Combination of benzotriazole and n-functionalized 2,5-di(2-thienyl)-1h-pyrrole units to investigate the electrochromic properties of conjugated polymers Rende, Eda; Çırpan, Ali; Department of Chemistry (2013) Synthesis of new conducting polymers is desired since their electrochemical and optical properties enable them to be used as active layers in many device applications. Benzotriazole and nfunctionalized 2,5-di(2-thienyl)-1h-pyrrole (SNS Series) containing polymers showed very promising results as electrochromic materials. In order to observe the effect of the combination of these two units three new monomers 2-(6-(2,5-bis(5-methylthiophen-2-yl)-1H-pyrrol-1-yl)hexyl)-4,7-di(thiophen-2- yl)-2H-benzo[d][1,2,3]t...
An electrochemically and optically stable electrochromic polymer film based on EDOT and 1,2,3,4-tetrahydrophenazine ERGÜN, EMİNE GÜL CANSU; Eroglu, Deniz (Elsevier BV, 2019-12-01) In this work, 3,4-ethylenedioxythiophene (EDOT) and 1,2,3,4-tetrahydrophenazine based donor-acceptor-donor type monomer (EBE) was synthesized, electropolymerized and the resulting polymer film (P(EBE)) was investigated in terms of its electrochemical and spectroelectrochemical properties. The polymer film showed excellent electrochemical stability upon 1000 switchings by saving almost full of its electroactivity. Moreover, 95% of the optical contrast was maintained after 500 switchings. The optical band gap...
The First Fabricated Dual-Band Uncooled Infrared Microbolometer Detector with a Tunable Micro-Mirror Structure Keskin, Selcuk; Akın, Tayfun (2012-04-27) This paper presents the first fabricated dual-band uncooled resistive infrared thermal microbolometer implemented with a resistive microbolometer and a tunable micro-mirror structure. Tunable reflective micro-mirrors are suspended underneath the suspended resistive microbolometers having a 35 mu m pixel pitch, and they are switched between two positions by the application of an electrostatic force for obtaining different responses in two wavelength infrared atmospheric windows, namely the 3-5 and 8-14 mu m,...
