Effect of annealing on the permeation characteristics of gases of coextruded LLDPE films
(Elsevier, 1996)
The temperature dependence of both the permeability and diffusion coefficients of carbon dioxide, oxygen and nitrogen in annealed LLDPE films are studied. It is found that the values of the permeability coefficient through ...
Diffusion, exclusion, and specific binding in a large channel: A study of OmpF selectivity inversion
(Elsevier, 2009)
We find that moderate cationic selectivity of the general bacterial porin OmpF in sodium and potassium chloride solutions is inversed to anionic selectivity in concentrated solutions of barium, calcium, nickel, and magnesium ...
Plasmonic versus catalytic effect of gold nanoparticles on mesoporous TiO2 electrodes for water splitting
(Elsevier, 2014-10)
Solar water splitting with metal oxide semiconductors constitutes a promising approach to the conversion of solar energy into chemical energy stored in the atomic bonds of hydrogen molecules. In the present study, we ...
Interfacial effects on dielectric properties of polymethylmethacrylate-titania microcomposites and nanocomposites
(Wiley, 2015)
It is discussed that dielectric properties of polymethylmethacrylate
(PMMA) composites are influenced by
the particle size of titania as a result of changes in the
structure and dynamics of polymer chains in the ...
Interfacial effects on dielectric properties of ethylene propylene rubber–titania nano- and micro-composites
(Springer Verlag, 2015)
The influence of titania particle size on dielectric properties of ethylene–propylene rubber (EPR) composites was investigated, with an emphasis on the chain dynamics in the interphase region. We hypothesized that a reduction ...
Ion channel activity of the CSFV p7 viroporin in surrogates of the ER lipid bilayer
(Elsevier, 2016-01)
Viroporins comprise a family of non-structural proteins that play significant and diverse roles during the replication cycle of many animal viruses. Consequently, they have become promising targets for inhibitory drug and ...
Impedance spectroscopic analysis of high-performance dye sensitized solar cells based on nano-clay electrolytes
(Elsevier, 2016)
In this work we present quasi-solid state dye-sensitized solar cells obtained employing artificial hydrotalcite nano-clay as electrolyte additive, with a greatly improved photo-energy conversion efficiency of up to 10.9% ...
On the different sources of cooperativity in pH titrating sites of a membrane protein channel
(EDP SciencesSocietà Italiana di FisicaSpringer-Verlag, 2016)
Cooperative interactions play a central role in the regulation of protein functions. Here we show that in multi-site systems like ion channels the application of the Hill formalism could require a combination of different ...
Photoelectrochemical water splitting with dual-photoelectrode tandem and parallel configurations: Enhancing light harvesting and carrier collection efficiencies
(Elsevier, 2023)
Photoelectrochemical (PEC) water splitting stands out as one of the most promising technologies to store solar
energy into chemical bonds and decarbonize industry and transport. In the present study, we develop ...
Directional ion selectivity in a biological nanopore with bipolar structure
(Elsevier, 2009)
Ion transport features of a biological nanopore, the bacterial porin OmpF from Escherichia coli, have been investigated by patch-clamp experiments performed at the single channel level. Membrane potential measurements done ...
