Fluctuations of Complex Networks: Electrical Properties of Single Protein Nanodevices

open access: yes, 2004
We present for the first time a complex network approach to the study of the electrical properties of single protein devices. In particular, we consider an electronic nanobiosensor based on a G-protein coupled receptor.

Modelization of Thermal Fluctuations in G Protein-Coupled Receptors

open access: yes, 2005
We simulate the electrical properties of a device realized by a G protein coupled receptor (GPCR), embedded in its membrane and in contact with two metallic electrodes through which an external voltage is applied.

Contribution to a better understanding of different behaviour patterns observed with organic coatings evaluated by electrochemical impedance spectroscopy [PDF]

open access: yes, 2009
In the present paper, three different coatings (epoxy, alkyd, polyurethane paints) were characterized by electrochemical impedance measurements, permeability tests, free-standing film impedance and local impedance measurements. The increase in resistance

Impedance Estimation with an Enhanced Particle Swarm Optimization for Low-Voltage Distribution Networks

open access: yesEnergies, 2019
Many researchers in recent years have studied voltage deviation issues in distribution networks. Characterizing the impedance between consuming nodes in a network is the key to controlling the network voltage.
