Crystalline porous covalent organic frameworks (COFs) with suitable redox-active sites were found to be useful as electrodes for capacitive energy storage. However, the bottleneck issues of COFs, i.e., their poor electrical conductivity and instability, greatly limit their practical implementation. Now, a strategy has been developed to overcome these obstacles and enable the use of COFs for hig...

The aim of this work was to determine the optimal synthesis conditions for preparation a poly(3,4-ethylenedioxythiophene) (PEDOT) layer by electrochemical method from an electrolyte containing graphene oxide (GO) and sodium dodecylsulfate (SDS) micellar solution. Besides SDS anion, GO is also incorporated within PEDOT as negative counter ion. Therefore, one-step PEDOT/GO composite preparation. ...

OBJECTIVE The aim of this study was to compare two different microelectrode materials--the conductive polymer composite poly-3,4-ethylenedioxythiophene (PEDOT)-carbon nanotube(CNT) and titanium nitride (TiN)--at activating spikes in retinal ganglion cells in whole mount rat retina through stimulation of the local retinal network. Stimulation efficacy of the microelectrodes was analyzed by compa...

Wiring liposomes and chloroplasts to the grid with an electronic polymer 2 Abstract We present a novel thylakoid based bio-solar cell capable of generating a photoelectric current of 0.7 µA/cm 2. We have introduced an electro conductive polymer, PEDOT-S, to the thylakoid membrane. PEDOT-S intervenes in the photosynthesis, captures electrons from the electron transport chain and transfers them d...

Abstract Conducting polymers with high theoretical capacitance and deformability are among the optimal candidates for compressible supercapacitor electrode materials. However, achieving both mechanical electrochemical stabilities in a single remains great challenge. To address this issue, “Polymer Chainmail” is proposed reversible deformation capability enhances stability because of steric hind...

Iron pyrite has been the material of interest in the solar community due to its optical properties and abundance. However, the progress is marred due to the lack of control on the surface and intrinsic chemistry of pyrite. In this report, we show iron pyrite as an efficient counter electrode (CE) material alternative to the conventional Pt and poly(3,4-ethylenedioxythiophene (PEDOT) CEs in dye-...

UNLABELLED Poly(3,4-ethylenedioxythiophene) doped with poly(styrenesulfonate), PEDOT PSS, has been utilized for over two decades as a stable, solution-processable hole conductor. While its hole transport properties have been the subject of intense investigation, recent work has turned to PEDOT PSS as a mixed ionic/electronic conductor in applications including bioelectronics, energy storage...

Coating microelectrodes with conductive polymer is widely recognized to decrease impedance and improve performance of implantable neural devices during recording and stimulation. A concern for wide-spread use of this approach is shelf-life, i.e., the electrochemical stability of the coated microelectrodes prior to use. In this work, we investigated the possibility of using the freeze-drying pro...

Bones have been shown to exhibit piezoelectric properties, generating electrical potential upon mechanical deformation and responding to electrical stimulation with the generation of mechanical stress. Thus, the effects of electrical stimulation on bone tissue engineering have been extensively studied. However, in bone regeneration applications, only few studies have focused on the use of elect...
