Crystalline electrical field effects on powdered RE Cu4Al8 (RE = Tb, Dy, Ho and Er) intermetallic compounds
(Elsevier, 2021-03)
In this work, structural and magnetic properties RE Cu4Al8 (RE = Tb, Dy, Ho and Er) family of compounds are reported. Measurements of X-ray diffraction, tem- perature (T) and magnetic eld (H) dependencies of magnetization ...
Determining concentration depth profiles in fluorinated networks by means of electric force microscopy
(American Institute Of Physics, 2011-08-11)
By means of electric force microscopy, composition depth profiles were measured with nanometric resolution for a series of fluorinated networks. By mapping the dielectric permittivity along a line going from the surface ...
Impedance spectroscopy applied to the fast wounding dynamics of an electrical wound-healing assay in mammalian cells
(IOP Publishing, 2015-06-25)
Electrical wound-healing assays are often used as a means to study in vitro cell migration and proliferation. In such analysis, a cell monolayer that sits on a small electrode is electrically wounded and its spectral ...
Structure and electrical properties of a one-dimensional polymeric silver thiosaccharinate complex with argentophilic interactions
(Wiley Blackwell Publishing, Inc, 2018-02)
Among the potential applications of coordination polymers, electrical conductivity ranks high in technological interest. We report the synthesis, crystal structure and spectroscopic analysis of an AgI–thiosaccharinate ...
In vitro electrical impedance spectroscopy of human dentine: The effect of restorative materials
(Wiley-liss, Div John Wiley & Sons Inc, 2008-04)
The influence of different restorative materials on in vitro dielectric properties of sound dentine was investigated. The studied samples were three-layer materials consisting of successive disks of dentine and silver ...

(Comité Español de Automática, 2020-05)
En este trabajo se propone un observador para estimar el par efectuado por un ciclista en el eje trasero de una bicicleta eléctrica cuya información es utilizada para aplicar una estrategia de asistencia al pedaleo que ...
Hydrogenated amorphous silicon characterization from steady state photoconductive measurements
(IOP Publishing, 2019-03)
We propose to use steady state measurements and a teaching-learning-based optimization (TLBO) algorithm to get the complete set of material transport parameters of disordered semiconductors, taking undoped hydrogenated ...
Effects of Ag presence on phases separation and order-disorder transitions in Cu-xAl-Mn alloys
(Elsevier Science SA, 2019-02)
The effects of Ag additions on phases separation and order-disorder transitions in the Cu-7Al-10Mn, Cu-9Al-10Mn and Cu-11Al-10Mn alloys have been studied using electrical resistivity measurements with temperature, differential ...
Electrical effective parameters of the grains and the Montgomery's method in Bi 1.65Pb 0.35Sr 2Ca 2.5Cu 3.5O y ceramics
(Springer, 2018-08)
In this paper we have applied the Montgomery's measurement method to Bi 1.65Pb 0.35Sr 2Ca 2.5Cu 3.5O y ceramic samples, to study the behavior of the grains? electrical effective parameters, such as: intrinsic effective ...
Assay based on electrical impedance spectroscopy to discriminate between normal and cancerous mammalian cells
(American Physical Society, 2018-03-19)
In this work we present an assay to discriminate between normal and cancerous cells. The method is based on the measurement of electrical impedance spectra of in vitro cell cultures. We developed a protocol consisting on ...
