We describe the synthesis of a novel electroactive photo‐crosslinkable poly(aryl ether), containing tetraaniline pendants and allyl groups (EPPAE). The polymer structure and spectral properties are studied in detail. By introducing the electroactive tetraaniline pandents, EPPAE reveals reversible electrochemical activity, expected electrochromic behavior and good anticorrosive performance. After crosslinking the allyl groups with UV exposure, the resultant polymer (c‐EPPAE) shows drastic change in electrochemical properties. The c‐EPPAE/ITO electrode exhibits declining electroactivity but excellent electrochemical stability, which are associated with densification of the electroactive layer. Furthermore, in the corrosive protection measurements, c‐EPPAE reveals an outstanding protection efficiency (99.92%) for stainless steel substrates. A comprehensive study of electrochromic properties and corrosive protection of EPPAE before and after UV exposure will provide an insightful tool for the developing electrochromic smart windows, electrochromic displays, and anticorrosive paint. © 2016 Wiley Periodicals, Inc.

Transient response of a dual clutch transmission (DCT) powertrain to synchroniser mechanism engagements is investigated using a lumped inertia model of the powertrain. Original research integrates lumped inertia powertrain models for the DCT with a detailed synchroniser mechanism model and two separate engine models, comprising of a mean torque model and a harmonic torque model, using torque derived from piston firing. Simulations are used to investigate the synchroniser mechanism engagement process in a previously unscrutinised operating environment. Simulations are performed using both engine torque models, with the mean torque model demonstrates the highly nonlinear nature of synchroniser mechanism engagement, and the powertrain response to the engagement process. Through the introduction of harmonic engine torques, additional excitation is present in the mechanism during engagement, and increased vibration of the synchroniser sleeve results. The impact of vibrations is particularly important to the increased wear of indexing chamfer contact surfaces. 相似文献

By applying the theory of quasiconformal maps in measure metric spaces that was introduced by Heinonen-Koskela, we characterize
bi-Lipschitz maps by modulus inequalities of rings and maximal, minimal derivatives in Q-regular Loewner spaces. Meanwhile the sufficient and necessary conditions for quasiconformal maps to become bi-Lipschitz
maps are also obtained. These results generalize Rohde’s theorem in ℝ

and improve Balogh’s corresponding results in Carnot groups.

Cardiac troponin I (cTnI) in the serum of patients has been established as a principal biochemical marker of myocardial damage1-4. Fast detection of cTnI will be helpful for the diagnosis of acute myocardial infarction (AMI), the identification of myocardial injury (MI) and the stratification of cardiac risk. A number of serological tests have been developed for the detection of cTnI. As known, among many methods, enzyme-linked immunosorbent assay (ELISA) and radioimmunoassay (RIA) wer… 相似文献

Determining the enantiomeric excess value of novel chiral compounds is of great importance in asymmetry synthesis. NMR1, HPLC and GC are the ordinary methods applied in this work. In recent years, capillary electrophoresis has been successfully used in chiral separation2. In this paper, we separated the enantiomer of (-pyrrolidinyl phenylpropanol (Figure 1) by capillary electrophoresis using (-cyclodextrin polymer as chiral selector. According to the ratio of peak area with migration time,… 相似文献
