Influence of the Ionic Strength in the Intrinsic Viscosity of Xanthan Gum. An Experimental Review
(Science and Education Publishing, 2015-12)
This study involves the influence of ionic strength in intrinsic viscosity of xanthan gum. The best concentration of monovalent and bivalent cations chloride salts is evaluated. The salt concentration is 0.001 M for ...
Extensive structural change of the envelope protein of dengue virus induced by a tuned ionic strength: conformational and energetic analyses
(SPRINGERDORDRECHT, 2012)
The Dengue has become a global public health threat, with over 100 million infections annually; to date there is no specific vaccine or any antiviral drug. The structures of the envelope (E) proteins of the four known ...
Determination of solubility product of mercurous acetate at various ionic strengths in aqueous medium
(Editora Unesp, 1996-01-01)
The conditionals (K-ps) and thermodynamics (K-ps(o)) solubility products of mercurous acetate have been determined, in aqueous solution, at 25 degrees C and ionic strength (I) comprised between 0.300 and 3.000 mol/L (NaClO4). ...

A Annona emarginata é capaz de acumular metais pesados essenciais sem causar danos ao seu metabolismo?
(2017-01-01)
This study aimed to evaluate if ionic strength variation causes differential accumulation of heavy metals in plants of Annona emarginata (Schltdl.) H. Rainer var. ‘terra-fria’, modifying gas exchange and dry matter production. ...
Influence of pH and ionic strength on the antibacterial effect of hyaluronic acid/chitosan films assembled layer-by-layer
(PERGAMON-ELSEVIER SCIENCE LTD, 2018)
Nickel adsorption in two Oxisols and an Alfisol as affected by pH, nature of the electrolyte, and ionic strength of soil solution
(SPRINGER HEIDELBERG, 2008)
Background, aim, and scope The retention of potentially toxic metals in highly weathered soils can follow different pathways that variably affect their mobility and availability in the soil-water-plant system. This study ...
Ionic medium effects on equilibrium constants .1. Proton, copper(II), cadmium(II), lead(II) and acetate activity coefficients in aqueous solution
(Elsevier B.V., 1996-10-01)
The molar single ion activity coefficients associated with hydrogen, copper(II), cadmium(II) and lead(II) ions were determined at 25 degrees C and ionic strengths between 0.100 and 3.00 M (NaClO4), whereas for acetate the ...
Effects of ph and ionic strength on the protease activity of gastric extracts from the coho salmon oncorhynchus kisutch
(Pontificia Universidad Católica de Valparaíso, 2019-11-07)
The activity of fish acid proteases is strongly dependent on the pH, and many basic and applied works had focused on researching the pH-profile of digestive proteases using different buffered media. Nevertheless, enzymatic ...
