Linearity, saturation and blocking in a large multiionic channel: divalent cation modulation of the OmpF porin conductance
(Elsevier, 2011-01)
Measurement of unitary conductance is a fundamental step in the characterization of a protein ion channelpermeabilizing a membrane. We study here the effect of salts of divalent cations on the OmpF channelconductance ...
Spectral broadening enhancement in silicon waveguides through pulse shaping
(Optical Society of America, 2012)
Spectral broadening in silicon waveguides is usually inhibited at telecom wavelengths due to some adverse effects related to semiconductor dynamics, namely, two-photon and free-carrier absorption (FCA). In this Letter, our ...
Dispersion requirements in coherent frequency-to-time mapping
(Optical Society of America, 2011)
The frequency-to-time mapping technique (also known as the
temporal far-field phenomenon) usually requires a significant amount of
dispersion to stretch an ultrashort optical pulse so that the intensity profile
becomes ...
First-passage-time analysis of atomic-resolution simulations of the ionic transport in a bacterial porin
(American Physical Society, 2011-02-16)
We have studied the dynamics of chloride and potassium ions in the interior of the Outer membrane porin F (OmpF) under the influence of an external electric field. From the results of extensive all-atom molecular dynamics ...
Origin of efficiency enhancement in Nb2O5 coated titanium dioxide nanorod based dye sensitized solar cells
(Royal Society of Chemistry, 2011-05-13)
Ordered one-dimensional metal oxides are considered promising architectures for dye-sensitized solar cells (DSC). Here we explore the properties determining the photovoltaic performance of DSC based on titanium dioxide ...
Bright visible-infrared light emitting diodes based on hybrid halide perovskite with Spiro-OMeTAD as a hole-injecting layer
(American Chemical Society, 2015-05)
Hybrid halide perovskites that are currently intensively studied for photovoltaic applications, also present outstanding properties for light emission. Here, we report on the preparation of bright solid state light emitting ...
PEDOT nanotube arrays as high performing counter electrodes for dye sensitized solar cells: study of the interactions among electrolytes and counter electrodes
(Wiley, 2011-10)
PEDOT nanotube arrays present a better catalytic activity with I−/I3− redox than standard platinized counter electrodes used for dye sensitized solar cells exhibiting thereby a photoconversion efficiency as high as 8.3%. ...
Temperature dependence of open-circuit voltage and recombination processes in polymer–fullerene based solar cells
(Elsevier, 2011)
In this article, we have studied the temperature and illumination dependence of open-circuitvoltage (VOC) in polymer–fullerenebasedsolarcells. It has been observed that VOC at higher illumination intensities gets converged ...
Enantiopure triazolium salts. Chemoenzymatic synthesis and applications in organocatalysis
(Wiley-VCH Verlag GmbH & Co. KGaA, 2011-10-14)
A novel family of triazolium salt enantiomers has been efficiently synthesized by combining chemical and biocatalytic methods. The stereoselective action shown by hydrolytic enzymes led to the design of simple and general ...
Influence of solvent on the network structure formed by free radical polymerization of tri-ethylene glycol dimethacrylate: A dielectric study
(Elsevier, 2010)
Molecular mobility of a series of tri-ethylene glycol dimethacrylate (TrEGDMA) samples polymerized with different amounts of ethyl acetate up to 40% (w/w) as diluent was investigated by dielectric relaxation spectroscopy. ...
