Science in the Age of Digital Networking
(American Chemical Society, 2015-08)
Today, the world is moving fast, but we do not know
exactly where this leads yet. As the economy of knowledge
inevitably extends its tentacles on the realm of science, what are
we –scientists- going to do? So far, an ...
Boosting Power Conversion Efficiencies of Quantum-Dot-Sensitized Solar Cells Beyond 8% by Recombination Control
(American Chemical Society, 2015)
At present, quantum-dot-sensitized solar cells (QDSCs) still exhibit moderate power conversion efficiency (with record efficiency of 6–7%), limited primarily by charge recombination. Therefore, suppressing recombination ...
Hole conductivity and acceptor density of p-type CuGaO2 nanoparticles determined by impedance spectroscopy: The effect of Mg doping
(Elsevier, 2013)
Delafossite materials like CuGaO2 have appeared as promising p-type semiconductor materials for their exploitation in tandem dye sensitized solar cells and water splitting photoelectrochemical cells. However, the intrinsic ...
Membrane Potential Bistability in Nonexcitable Cells as Described by Inward and Outward Voltage-Gated Ion Channels
(American Chemical Society, 2014-10)
The membrane potential of nonexcitable cells, defined as the electrical potential difference between the cell cytoplasm and the extracellular environment when the current is zero, is controlled by the individual electrical ...
