Agar-based films for application as polymer electrolytes
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
New types of polymer electrolytes based on agar have been prepared and characterized by impedance spectroscopy, X-ray diffraction measurements, UV-vis spectroscopy and scanning electronic microscopy (SEMI). The best ionic ...
Flotation in concentrated electrolyte solutions
(2015)
In the flotation in highly concentrated electrolyte solutions not only ionic strength but also chemical composition, flotation pH and mineral properties play an important role. As a result an improvement or depression may ...
Poly(acrylonitrile)-montmorillonite nanocomposites Effects of the intercalation of the filler on the conductivity of composite polymer electrolytes
(ELSEVIER, 2010)
In this work, a series of composite polymer electrolytes (CPEs) basically constituted by polyacrylonitrile
(PAN) and a clay, montmorillonite (Bentonite), as filler have been developed, in which the clay in its
lithiated ...

Association between heart rate, heart rate variability, cortisol, glucose and electrolytes in healthy newborn calves
(Arquivo Brasileiro Medicina Veterinaria Zootecnia, 2019-11-01)
This study aims at evaluating the effects of electrolytes, glucose and cortisol levels over heart rate (HR) and heart rate variability (HRV) in healthy newborn calves. Seventeen healthy Holstein calves were evaluated during ...
Chemical stability and electrical properties of Nb doped BaCe 0.9Y 0.1O 3-δ as a high temperature proton conducting electrolyte for IT-SOFC
(2013-01-01)
BaCe 0.9-xNb xY 0.1O 3-δ (where x=0, 0.01, 0.03 and 0.05) powders were synthesized by solid-state reaction to investigate the influence of Nb concentration on chemical stability and electrical properties of the sintered ...
Influence of the electrolyte concentration on the smooth TiO2 anodic coatings on Ti-6Al-4V
(MDPI, 2017-03)
To obtain smooth TiO2 coatings for building a new design of Ti-6Al-4V heart valve, the anodic oxidation technique in pre-spark conditions was evaluated. TiO2 coating is necessary for its recognized biocompatibility and ...

Dietary electrolyte balance for broiler chickens under moderately high ambient temperatures and relative humidities
(2003-02-01)
Cobb male broiler chicks (1,000) on new litter were used to evaluate effects of dietary electrolyte balance [DEB; Na+K-Cl, milliequivalents (mEq) per kilogram] under tropical summer conditions. Corn-soybean meal-based mash ...
