Carrier density and interfacial kinetics of mesoporous TiO2 in aqueous electrolyte determined by impedance spectroscopy
(Elsevier, 2012)
Water splitting at a semiconductor/solution interface with the only input of sunlight to generate hydrogen is one of the most attractive strategies to produce and store chemical energy. In the present study we have ...
Interpretation of trap-limited mobility in space-charge limited current in organic layers with exponential density of traps.
(© American Institute of Physics, 2011-08)
Charge carrier transport in disordered organic semiconductors, performed in electronic devices such as optoelectronic and photovoltaic ones, is usually affected by an exponential distribution of localized states in the ...
Water oxidation at hematite photoelectrodes: the role of surface states
(American Chemical Society, 2012)
Hematite (α-Fe2O3) constitutes one of the most promising semiconductor materials for the conversion of sunlight into chemical fuels by water splitting. Its inherent drawbacks related to the long penetration depth of light ...
Investigation on Microwave Absorption Properties for Multiwalled Carbon Nanotubes/Fe/Co/Ni Nanopowders as Lightweight Absorbers
(ACS, 2011-06)
Multiwalled carbon nanotubes (MWCNTs)/Fe, MWCNTs/Co, and MWCNTs/Ni nanopowders have been prepared conveniently by a simple chemical method. The excellent microwave absorption properties in S-band have been obtained due to ...
Olefin Epoxidation by Molybdenum Peroxo Compound: Molecular Mechanism Characterized by the Electron Localization Function and Catastrophe Theory
(ACS, 2011-02)
The oxygen atom transfer reaction from the Mimoun-type complex MoO(η2-O2)2OPH3 to ethylene C2H4 affording oxirane C2H4O has been investigated within the framework of the Bonding Evolution Theory in which the corresponding ...
Protein Ion Channels as Molecular Ratchets. Switchable Current Modulation in Outer Membrane Protein F Porin Induced by Millimolar La3+ Ions
(American Chemical Society, 2012)
The quest for innovative tunable nanodevices has mainly focused on switches that modulate their properties through engineered conformational changes. We propose here an alternative route that takes advantage of the crucial ...
Effect of the bridge substitution on the efficiency of dye-sensitized solar cells
(Elsevier, 2012-12)
We have designed and synthesized a novel D–π–A dye based on zinc porphyrin as the donor, cyanoacrylic acid as the acceptor and trans-bis(3,4-ethylenedioxythiophene)vinylene as the bridge. Under standard global AM 1.5 solar ...
Panchromatic sensitized solar cells based on metal sulfide quantum dots grown directly on nanostructured TiO2 electrodes
(American Chemical Society, 2011-02)
The use of narrow band gap semiconductors such as PbS may expand the light absorption range to the near-infrared region in quantum-dot-sensitized solar cells (QDSCs), increasing the generated photocurrent. However, the ...
