Impedance spectroscopy and membrane potential analysis of microfiltration membranes. The influence of surface fractality
(Pergamon-Elsevier Science Ltd, 2018-03)
In this work, the proper charge density of a microfiltration membrane has been determined by using two different methods. Firstly, the ionic transport of a KCl solution has been investigated by simultaneous measurements ...
Structural and electrochromic study of polypyrrole synthesized with azo and anthraquinone dyes
(Elsevier Science SaLausanneSuíça, 2006)
Understanding the physical systems from their underlying geometrical and topological properties
(Springer, 2016-01)
As it is well known, a certain lack of theoretical understanding of the mechanisms governing the various phenomena exists in several areas of physics. In particular, it concerns those which involve transport of charged ...
Diffusion of a dipolar tracer in a salty surface

Modeling the sorption kinetic of metsulfuron-methyl on Andisols and Ultisols volcanic ash-derived soils: Kinetics parameters and solute transport mechanisms
(2010)
Metsulfuron-methyl sorption kinetic was studied in Andisol and Ultisol soils in view of their distinctive physical and chemical properties: acidic pH and variable surface charge. Different kinetic models were applied to ...
Charge transfer mechanism of WO3/TiO2 heterostructure for photoelectrochemical water splitting
(2017-04-15)
The present study shows how electronic parameters (e.g. band gap energy, band edge positions) on semiconductors affect photoelectrochemical activity in simulated solar light using WO3, TiO2 and WO3/TiO2 as model systems. ...
Electrochemical insight into the mechanism of electron transport in biofilms of Geobacter sulfurreducens
(Elsevier, 2011-07-08)
Electroactive bacterial biofilms can be produced on a polarized electrode by forcing its use as the final electron acceptor for bacterial respiration. This strategy offers the researcher the unique possibility to control ...
Exploring the properties of niobium oxide films for electron transport layers in perovskite solar cells
(2019-01-01)
In this work, niobium oxide films were deposited by reactive magnetron sputtering under different oxygen flow rate and applied as electron transport layer in perovskite solar cells. It was found that the deposition made ...
