Considerable progress has been made in the last decade in implantable bioelectronic neurosystems. Yet most neural implants are used in acute and tethered experimental conditions. Here, we present a preliminary prototype of a multichannel system for simulta ...

The performance enhancement of dye-sensitized solar cells (DSCs) in lithium-free and lithium-containing electrolytes under visible light-soaking was examined by impedance spectroscopy and photovoltage transient decay measurements. The improvement was found ...

Dye-sensitized solar cells with power conversion efficiencies of up to 6.5% have been fabricated using a cobalt trisbipyridyl redox mediator with the cis-diisothiocyanato-(2,2'-bipyridyl-4,4'-dicarboxylic acid)-(2,2'-bipyridyl-4,4'-dinonyl) ruthenium(II) ( ...

The poor electronic conductivity of LiFePO4 has been one of the major issues impeding it from achieving high power and energy density lithium-ion batteries. In this communication, a novel polymer-wiring concept was proposed to improve the conduction of the ...

Replacing the nonyl groups on the solar cell dye Ru(4,4'-carboxylic acid-2,2'-bipyridine)-( 4,4'-dinonyl-2,2'-bipyridine)(NCS)(2) (Z-907) with amino groups results in a marked decrease in solar cell performance. This is despite the fact that the amino deri ...

To apply impedance spectroscopy (IS) for studying charge transport in the mesoporous film of solid-state dye-sensitized solar cells (ss-DSCs), it is necessary to determine the relative conductivities of the electron and hole transporting phases, given the ...

The serine protease prostasin (CAP1/Prss8, channel-activating protease-1) is a confirmed in vitro and in vivo activator of the epithelial sodium channel ENaC. To test whether proteolytic activity or CAP1/Prss8 abundance itself are required for ENaC activat ...

Developing high-performance, low-cost electrocatalysts for the reduction reaction at the cathode of dye-sensitized solar cells (DSCs) is important for their commercialization. Here, we introduce the concept of redox catalysis for improving counter-electrod ...

Reversible chemical delithiation/lithiation of LiFePO4 was successfully demonstrated using ferrocene derivatives, based on which a novel energy storage system - the redox flow lithium-ion battery (RFLB), was devised by integrating the operation flexibility ...

The conventional strategy of overcharge protection for lithium ion batteries uses redox molecules having oxidation potential higher than the cathodic materials in the electrolyte. Here we propose a novel approach by using redox molecules having reduction p ...

A compact energy‐storage system based on redox targeting is proposed, by which insulating LiFePO4 particles can be reversibly charged and discharged by redox shuttle molecules (S; see scheme) even in the absence of conducting additives. The energy density ...

With the aim of improving the rate capability and the safety of nanocrystalline Li4Ti5O12-based high power lithium ion batteries, two high boiling point nitrile-based electrolytes namely, 3-ethoxypropionitrile (CH3CH2OCH2CH2CN, EPN)/1 M LiTFSI and 3-(2,2,2 ...

A low-cost electrochromic (EC) window based on a redox-flow system that does not require expensive transparent conductive oxide (TCO) substrates is introduced and demonstrated for the first time. An aqueous I-3/I redox electrolyte is used in place of a TCO ...
