Microstructural Evolution of Cold-Deformed and Isothermally Treated ZA27 Alloys
(Universidade Federal de São Carlos, 2021-06)
Pure ZA27 alloys and ZA27 alloys with Cu and Mg additions were cast and deformed by compression. Samples of both alloys were heat treated at 460°C after deformation and the evolution of the microstructure as a function of ...
Non-isothermal model for nematic spherulite growth
(American Chemical Society, 2008-12)
A computational study of the growth of two-dimensional nematic spherulites in an isotropic phase was performed using a Landau-de Gennes-type quadrupolar tensor order parameter model for the first-order isotropic/nematic ...
Phenomenological models for the isothermal physical aging of PEEK
(Elsevier, 2018)
Interfacial and emulsifying properties of amaranth (Amaranthus hypochondriacus) protein isolates under different conditions of pH
(Elsevier Science, 2012-01)
Amaranth proteins have adequate amino acid balance for substituting either partly or completely animal proteins in human nutrition. However, they present poor emulsifying properties in basic conditions corresponding to ...
Direct detection of Tritrichomonas foetus in cattle genital fluid trough loop mediated isothermal amplification of elongation factor 1 alpha 1
(Elsevier Science, 2018-09)
Testing for Tritrichomonas foetus and exclusion of infected animals is an effective way of improving the reproductive efficiency in a herd. Conventional PCR is inherently more specific than the culture method and quantitative ...
Comparison of arsenate adsorption from neutral pH aqueous solutions using two different iron-trimesate porous solids: Kinetics, equilibrium isotherms, and synchrotron X-ray absorption experiments
(Springer, 2020-10-06)
We have explored the use of two different iron-based porous materials for arsenic uptake from neutral pH aqueous solutions. Both materials are reminiscent of a material known as MIL-100(Fe), a Metal Organic Framework (MOF) ...
Moisture sorption properties and glass transition temperature of a non-conventional exudate gum (Prosopis alba) from northeast Argentine
(Elsevier Science, 2020-05)
Water-solid interactions were explored in purified and freeze-dried Prosopis alba exudate gum as approach to get a deeper insight of structural and functional aspects of this novel biomaterial. Particularly, the study of ...
Propolis encapsulation by spray drying: Characterization and stability
(Elsevier Science, 2017-01)
Propolis extracts have shown to possess several health beneficial properties attributed to their phenol composition. Several pharmaceutical formulations are based on propolis as active ingredient and it could also be a ...
Control of the adsorption properties of alginate - guar gum matrix functionalized with epichlorohydrin through the addition of different flexible chain polymers as toll for the chymotrypsinogen isolation
(Elsevier Science, 2018-08)
This work addresses the obtaining and characterization of alginate-guar gum matrix, cross-linked with epichlorohydrin in the presence of different flexible chain polymers: polyvinyl alcohol, polyvinyl pyrrolidine and ...
