There is an increasing demand in the flexible electronics industry for highly robust flexible/transparent conductors that can withstand high temperatures and corrosive environments. In this work, outstanding thermal and ambient stability is demonstrated for a highly transparent Ag nanowire electrode with a low electrical resistivity, by encapsulating it with an ultra-thin Al2O3 film (around 5.3...

The development of electrodes composed of non-noble-metal catalysts with both excellent activity and high stability for the hydrogen evolution reaction (HER) is essential for hydrogen production. In this work, a flexible and robust film electrode based on cobalt nanoparticles embedded into the interlamination of N-doped graphene film (Co@NGF) is fabricated by simple vacuum filtration combined w...

Here we report a simple strategy to prepare three-dimensional graphene gel coated on nickel foam for supercapacitor applications by a simple 'dipping and drying' process. The supercapacitors based on three-dimensional graphene gel (G-gel@NF-1) exhibited high rate capability of 152 F g(-1) at 0.36 A g(-1) and 107 F g(-1) at 90.9 A g(-1), good cycle stability with capacitance retention of 89% aft...

Flexible Memristive Organic Solar Cells In article number 2300433, Tae Geun Kim and co-workers report a flexible organic solar cell (OSC) with memory learning functionalities (memristive OSC) using highly flexible, transparent, conductive electrode based on multilayer MXene/Ag/MXene structures. The approach provides critical clues to the production of compact intelligent future modules.

Highly efficient organic light emitting diodes (OLEDs) based on multiple layers of vapor evaporated small molecules, indium tin oxide transparent electrode, and glass substrate have been extensively investigated and are being commercialized. The light extraction from the exciton radiative decay is limited to less than 30% due to plasmonic quenching on the metallic cathode and the waveguide in t...

This work presents a simple, flexible and economical microwire array electrode for extracellular cortical recordings. The proposed procedure is relatively simple, even for a novice worker to implement in-house. These main steps include design and sculpturing PCB, straightening microwires, connecting PCB pattern, arraying and soldering microwires and packaging the microelectrode. A practiced res...

In this article, we have synthesized a series of nitrogen-doped nanoporous carbon (NPC) from metal organic framework of UiO-66 with different ratios of adenine and 1,4-benzendicarboxylate (H2BDC) coated on carbon nanotube film (CNTF) to obtain a flexible porous electrode (NPC/CNTF). It is worth noting that the introduction of adenine at different ratios did not change the structure of UiO-66. W...

In most cases of atrioventricular block with Adams-Stokes attacks the application of either an endocardial or an epicardial electrode for artificial pacing can be performed in the operating-theatre with all necessary equipment available. In some cases, however, the situation is more dramatic: electrical pacing may be necessary without any delay, and it may be impossible to transfer the patient ...

Microsupercapacitors (MSCs) are promising energy storage devices to power miniaturized portable electronics and microelectromechanical systems. With the increasing attention on all-solid-state flexible supercapacitors, new strategies for high-performance flexible MSCs are highly desired. Here, we demonstrate all-solid-state, flexible micropseudocapacitors via direct laser patterning on crack-fr...

This paper reports a mechanically flexible, transparent thin film transistor that uses graphene as a conducting electrode and single-walled carbon nanotubes (SWNTs) as a semiconducting channel. These SWNTs and graphene films were printed on flexible plastic substrates using a printing method. The resulting devices exhibited a mobility of ∼ 2 cm(2) V(-1) s -1), On/Off ratio of ∼ 10(2), transmitt...
