Transient soft bioelectronics are capable of forming conformal contacts with curvilinear surfaces of biological host tissues and organs. Such systems are often subject to continuous static and dynamic loads from the biological host. In this article, we present investigation of electronic attributes of transient soft bioelectronic circuits subjected to mechanical force and influence of substrate's transiency on the transiency of the whole device; also, characterize and quantify loss of functionality in triggered devices. Variations in the electrical conductivity of circuits as a function of applied mechanical load was used as a means to deduce electronic characteristics under stress. The experimental results suggest that there exists a correlation between electronic properties of circuits and applied mechanical strain; no clear correlation was, however, observed between electronic properties of circuits and frequency of the applied dynamic load. Control over transiency rate of identical circuits utilizing the transiency characteristics of the poly(vinyl alcohol)l‐based substrates is also studied and demonstrated.

Spectroelectrochemical and Photovoltaic Characterization of a Solution-Processable n-and-p Type Dopable Pyrrole-Bearing Conjugated Polymer Baran, Derya; Balan, Abidin; Esteban, Beatriz-Meana; Neugebauer, Helmut; Sariciftci, Niyazi Serdar; Toppare, Levent Kamil (Wiley, 2010-12-15) D-A-D-type polymers are of high interest in the field of photovoltaics and electrochromism. In this study we report the synthesis and electrochemical properties of PPyBT along with its photophysical properties and photovoltaic performance. PPyBT is soluble in common organic solvents and both n- and p-type dopable, which is a desired property for conjugated polymers. During electrochemistry studies, the onset potentials of the polymer were determined as +0.2V for oxidation and -1.4V for reduction. Using thes...
Poly(ethylene terephthalate)/Carbon Nanotube Composites Prepared With Chemically Treated Carbon Nanotubes Yesil, Sertan; Bayram, Göknur (Wiley, 2011-07-01) Surfaces of multiwalled carbon nanotubes (CNT) were functionalized by treatment with strong acid mixture (purification) followed by modification with sodium dodecyl sulfate, poly(ethylene glycol) (PEG), and diglycidyl ether of Bisphenol A (DGEBA). Poly(ethylene terephthalate) (PET)-based conductive polymer composites were prepared by using these CNT by means of melt mixing with a twin screw extruder. Amount of carboxylic acid groups on the CNT surface increased after acid treatment but decreased with surfac...
Enzymatic Mineralization of Hydrogels for Bone Tissue Engineering by Incorporation of Alkaline Phosphatase Douglas, Timothy E. L.; Messersmith, Philip B.; Chasan, Safak; Mikos, Antonios G.; de Mulder, Eric L. W.; Dickson, Glenn; Schaubroeck, David; Balcaen, Lieve; Vanhaecke, Frank; Dubruel, Peter; Jansen, John A.; Leeuwenburgh, Sander C. G. (Wiley, 2012-08-01) Alkaline phosphatase (ALP), an enzyme involved in mineralization of bone, is incorporated into three hydrogel biomaterials to induce their mineralization with calcium phosphate (CaP). These are collagen type I, a mussel-protein-inspired adhesive consisting of PEG substituted with catechol groups, cPEG, and the PEG/fumaric acid copolymer OPF. After incubation in Ca-GP solution, FTIR, EDS, SEM, XRD, SAED, ICP-OES, and von Kossa staining confirm CaP formation. The amount of mineral formed decreases in the orde...
Electrochemical properties of a new star-shaped pyrrole monomer and its electrochromic applications Ak, Metin; Ak, Mine Sulak; Toppare, Levent Kamil (Wiley, 2006-08-02) A new monomer, 2,4,6-tris(4-(1H-pyrroI-1-yl) phenoxy)-1,3,5-triazine (Tria-Py) was synthesized via the reaction,of 4-(1H-pyrrol-1-yl)phenol with 2,4,6-trichloro-1,3, 5-triazine. It was electrochemically polymerized in a dichloromethane/acetonitrile solvent mixture. The polymer P(Tria-Py) was characterized via CV, FTIR, SEM and uv-vis spectroscopy. Spectroelectrochemical analysis revealed electronic transitions at 346, 508 and 665, nm, revealing pi to pi* transitions, and polaron and bipolaton band formation...
Theoretical investigations of the equol molecule: semi-empirical and density functional theory calculations Erkoc, F; Yilmazer, M; Erkoç, Şakir (Elsevier BV, 2005-01-14) The structural and electronic properties of the equol molecule, an estrogenic isoflavone. have been investigated theoretically by performing semi-empirical self-consistent field molecular orbital and density functional theory calculations. The geometry of the system has been optimized at the level of AMI method and the electronic properties have been calculated at the level of B3LYP functional.
