Relevance of Viroporin Ion Channel Activity on Viral Replication and Pathogenesis
(MDPI, 2015-07)
Modification of host-cell ionic content is a significant issue for viruses, as several viral proteins displaying ion channel activity, named viroporins, have been identified. Viroporins interact with different cellular ...
Relaxation dynamics of poly(vinylidene fluoride) studied by dynamical mechanical measurements and dielectric spectroscopy
(EDP SciencesSocietà Italiana di FisicaSpringer, 2012)
The aim of this study is to analyze the mobility of polymer chains in semicrystalline poly(vinylidene fluoride) (PVDF). PVDF crystallizes from the melt in the α crystalline phase. The transformation
from the α phase to the ...
Equivalent Circuit of Electrons and Holes in Thin Semiconductor Films for Photoelectrochemical Water Splitting Applications
(American Chemical Society, 2012)
A simple model for the kinetics of electrons and holes in a thin semiconductor film in photoelectrochemical water splitting conditions is discussed, with a focus to discriminate between trap-assisted recombination and ...
Divalent Metal Ion Transport across Large Biological Ion Channels and Their Effect on Conductance and Selectivity
(Hindawi Publishing Corporation, 2012-07)
Electrophysiological characterization of large protein channels, usually displaying multi-ionic transport and weak ion selectivity, is commonly performed at physiological conditions (moderate gradients of KCl solutions at ...
Effect of nanostructured electrode architecture and semiconductor deposition strategy on the photovoltaic performance of quantum dot sensitized solar cells
(Elsevier, 2012)
Here we analyze the effect of two relevant aspects related to cell preparation on quantum dot sensitized solar cells (QDSCs) performance: the architecture of the TiO2 nanostructured electrode and the growth method of quantum ...
Probing Tubulin-Blocked State of VDAC by Varying Membrane Surface Charge
(Biophysical Society, 2012-05)
Coronavirus E protein forms ion channels with functionally and structurally-involved membrane lipids
(Elsevier, 2012-10)
Coronavirus (CoV) envelope (E) protein ion channel activity was determined in channels formed in planar lipid bilayers by peptides representing either the transmembrane domain of severe acute respiratory syndrome CoV ...
Characterization of nanostructured hybrid and organic solar cells by impedance spectroscopy
(RSC Publishing, 2011-04-06)
We review the application of impedance spectroscopy in dye-sensitized solar cells, quantum dot-sensitized solar cells and organic bulk heterojunction solar cells. We emphasize the interpretation of the impedance parameters ...
Increased salt concentration promotes competitive block of OmpF channel by protons
(Elsevier, 2012-11)
Porins are channel-forming proteins that are located in the outer membranes (OM) of Gram-negative bacteria
and allow the influx of hydrophilic nutrients and the extrusion of waste products. The fine regulation of the
ion ...
Divalent cations reduce the pH sensitivity of OmpF channel inducing the pKa shift of key acidic residues
(RSC Publishing, 2010-11-03)
In contrast to the highly-selective channels of neurophysiology employing mostly the exclusion mechanism, different factors account for the selectivity of large channels. Elucidation of these factors is essential for ...
