A new soluble conducting polymer and its electrochromic devices
YİLDİZ, UMİT HAKAN; SAHİN, ELİF; Akhmedov, IM; Tanyeli, Cihangir; Toppare, Levent Kamil (Wiley, 2006-04-01)
A new polythiophene derivative was synthesized by both chemical and electrochemical oxidative polymerization of 1-(1-phenylethyl)-2,5-di(2-thienyl)-1H-pyrrole (PETPy). Of which the chemical method produces a polymer that is completely soluble in organic solvents. The structures of both the monomer and the soluble polymer were elucidated by nuclear magnetic resonance (H-1 and C-13 NMR) and Fourier transform infrared (FTIR) spectroscopy. The average molecular weight has been determined by gel permeation chrom...
A new model for distributed mems transmission lines
Topalli, K; Unlu, M; Sagkol, H; Demir, S; Aydın Çivi, Hatice Özlem; Koc, S; Akın, Tayfun (2004-06-26)
This paper presents a new model for the distributed MEMS transmission line (DMTL) structure where the MEMS bridges that are placed periodically on a high-impedance transmission line are represented as low-impedance transmission lines, rather than a lumped CLR circuit. The model includes LC networks at the transition point from high-impedance to low-impedance lines to account for the effects of discontinuity. The accuracy of the model is verified with measurements on three types of DMTLs that are fabricated ...
A new and efficient synthesis of indenone
Zengin, M; Dastan, A; Balcı, Metin (2001-01-01)
Reaction of dichloroketone 2 with NEt3 gave indenone (4) in high yield. Catodic reaction of 2 in the presence of C/Pt electrodes afforded the rearranged product 3 in high yield besides a small amount of chlorohydroxyketone 5. Reaction of rearranged dichloroketone 3 with NEt3 provided indenone (4) as the sole product. The mechanism of these reaction was discussed.
A New active control application for reduction of environmental noise in open spaces
Ülgen, Serkan; Sorguç, Arzu; Department of Building Science in Architecture (2016)
Today, rapid development of urban and industrial areas, growing motorway, airway and railway networks together with other sources, bring out noise as one of the major environmental problems. Studies show that one of the most annoying noise sources is the traffic noise in the cities. Sound barriers are conventional solutions applied to control traffic noise. However, the construction cost of these barriers, their aesthetical qualities and how they contribute to urban qualities are questionable. Today’s moder...
