Influence of the crosslinking content on the structural properties of polybutadiene rubbers with different isomeric composition
(Trans Tech Publications, 2016-12)
In the present work first results on structural properties of three commercial isomers of polybutadiene rubber are presented. To this aim, rheometry, PALS, DSC and swelling techniques were used. Different samples were ...
Modeling water uptake in a cereal grain during soaking
(Elsevier, 2010-03)
A diffusion equation to describe the isothermal absorption of liquid water in a spherical solid that undergoes uniform swelling was derived. The resulting partial differential equation was solved using a finite difference ...
Formulation and characterization of hydrogel based on pectin and brea gum
(Elsevier Science, 2019-02)
A hydrogel is a three-dimensional network formed by flexible chains of polymers that absorb considerable amounts of water. The objectives of this work were to formulate hydrogels from pectin and brea gum and to study their ...
Electrospun Mats: From White to Transparent with a Drop
(Wiley VCH Verlag, 2018-07)
In this article, the transparency of hydrophilic electrospun mats is studied. Results showing how transmittance varies under the action of water are presented. It is observed that swelling plays a crucial role in the ...

Se investigó el hinchamiento de la madera de Eucalytus grandis de Argentina, utilizando muestras seleccionadas al azar de plantaciones ubicadas en las provincias de Corrientes y Entre Ríos. Los materiales y los métodos ...
Modelling corn starch swelling in batch systems: effect of sucrose and hydrocolloids
(Elsevier, 2003-06)
Hydrocolloids are used in starch-based products to improve stability and to obtain specific textural characteristics. In stirred batch systems with constant jacket temperature, xanthan gum, guar gum and sodium alginate (1% ...
Kinetics of human sperm acrosomal exocytosis
(Oxford University Press, 2014-09-01)
The acrosome reaction is a unique event in the lifespan of sperm characterized by the exocytosis of the acrosomal content and the release of hybrid vesicles formed by patches of the outer acrosomal membrane and the plasma ...
