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 ...
Electrodeposition in highly viscous media: Experiments and simulations
(Elsevier Science, 2009-07)
Electrolyte viscosity plays an important role in ion transport. Here we study the effects of high viscosity variations in thin-layer electrochemical deposition (ECD) under constant-current conditions through experimental ...
Viscosity of supercooled aqueous glycerol solutions, validity of the Stokes-Einstein relationship, and implications for cryopreservation
(Academic Press Inc Elsevier Science, 2012-10)
The viscosity of supercooled glycerol aqueous solutions, with glycerol mass fractions between 0.70 and 0.90, have been determined to confirm that the Avramov-Milchev equation describes very well the temperature dependence ...
Flash point, kinematic viscosity and refractive index: variations and correlations of biodiesel–diesel blends
(Brazilian Society of Mechanical Sciences & Engineering, 2020-06-01)
This paper presents characterization studies of flash point, kinematic viscosity and refractive index for several biodiesel/ diesel blends. Biodiesel is produced from soybean, corn, olive, canola, almond, grape and peanut ...
Importancia de la medición de la Viscosidad sanguínea: retos y limitaciones
(Colegio Médico del Pérú, 2023-07-31)
La sangre es una mezcla de componentes que tiene su propia identidad. Una de las propiedades físicas que adquiere es su viscosidad, la cual es la resistencia que ofrece para desplazarse. A diferencia de ...
Efecto del polímero carboximetil celulosa de sodio sobre la inversión de emulsiones
(Ciencia e Ingeniería, 2010)
Viscosity as a key factor in decision making of nectar feeding ants
(Pergamon-Elsevier Science Ltd, 2021-01)
It is well known that viscosity reduces the intake rates in nectar-feeding insects, such as nectivorous ants, though it remains unclear whether viscosity imposes a higher energy investment in these insects, and how this ...
Procedure to Evaluate the Shear Rate Profile and the Apparent Viscosity of Non-Newtonian Fluids in the Falling Cylinder Viscometer
(Planta Piloto de Ingeniería Química, 2007-12)
The falling cylinder viscometer (FCV) is a reliable instrument to quantify the viscosity of Newtonian fluids. Nevertheless, when non-Newtonian fluids are tested in this device, difficulties appear to determine the apparent ...
Volumetric and viscosity properties of water-in-salt lithium electrolytes: A comparison with ionic liquids and hydrated molten salts
(Academic Press Ltd - Elsevier Science Ltd, 2021-07)
The density and viscosity of LiTf, LiTFSI and LiTFSI + LiTf (mole ratio 3:1) aqueous solutions have been measured at temperatures between 25 °C and 55 °C, over a wide range of concentrations covering the Water-in-Salt (WiS) ...
Interfacial Dynamics and its relations with "negative" surface viscosities measured at water-air interfaces covered with a cationic surfactant
(American Chemical Society, 2019-06)
We studied the dynamics of a cationic surfactant monolayer, Gemini 12-2-12, at the air-water interface for surfactant aqueous solutions at concentrations below the critical micelle concentration. We present surface rheology ...
