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 ...
A scanning electrochemical microscopy (SECM) protein detection methodology has been developed based on the tagging of free cysteines and other nucleophiles in proteins and peptides by benzoquinone. The tagged proteins are detected by the mediated reduction ...
Vanadium redox flow batteries (VRB) are large stationary electricity storage systems; their performance is enhanced when they are operating under optimal conditions. The multiphysics model developed in this paper offers a good understanding of the VRB oper ...
Addn. of 4-tert-butylpyridine (4TBP) to redox electrolytes used in dye-sensitized TiO2 solar cells has a large effect on their performance. In an electrolyte contg. 0.7M LiI and 0.05M I2 in 3-methoxypropionitrile, addn. of 0.5M 4TBP gave an increase of the ...
The common technology for solid oxide fuel cells (SOFC) is based on a cermet anode of nickel with yttrium stabilized zirconia (YSZ), often used as the supporting structure. One of the main limitations of this anode technology is the redox tolerance. In thi ...
New concepts of power generation, the emergence of renewable energies as well as the liberalization of the electrical market have recently raised strong intereset in electricity storage technologies. The vanadium redox flow battery (VRB) is among the new s ...
Density functional theory (DFT)-based Car-Parrinello molecular dynamics (CPMD) simulations describe the time evolution of molecular systems without resorting to a predefined potential energy surface. CPMD and hybrid molecular mechanics/CPMD schemes have re ...
Photoinduced absorption spectroscopy, where the excitation is provided by a square-wave modulated (on/off) monochromatic light source, is a versatile tool in the study of dye-sensitized solar cells. Spectra of transient species, such as the oxidized dye, c ...
This contribution proposes the study of an ‘On-Line’ UPS, where adaptations have been made to replace the initial batteries with supercapacitors. As the electrical behavior of supercapacitors is different from that one of lead-acid batteries, a power elect ...
