Homogenización computacional aplicada al estudio de suelos tipo conglomerado del austro ecuatoriano
(Universidad de Cuenca, 2010-12)
The soil type in Cuenca, Southern Ecuador, is called conglomerado (conglomerate, a heterogeneous soil composed of a mixture ranging from decimetric stones to clay). Experimental values of the characteristics of this material ...
Influence of ZrO2 nanoparticles and thermal treatment on the properties of PMMA/ZrO2 hybrid coatings
(2015-07-29)
In this work, ZrO2 nanoparticles were synthesized by the sol-gel method, treated thermally at different temperatures (400, 600 and 800 °C), and added to a polymer matrix in two different weight percentages (0.5 and 1) by ...

Thermomechanical characterization of PVDF and P(VDF-TrFE) blends containing corn starch and natural rubber
(Springer, 2010-02-01)
Films of poly(vinylidene fluoride), PVDF, and poly(vinylidene fluoride-trifluoroethylene), P(VDF-TrFE), containing corn starch and latex of natural rubber as additives were produced by compressing/annealing forming blends ...
Corrosion behavior of Ti-13Nb-13Zr alloy used as a biomaterial
(Elsevier B.V. Sa, 2009-05-12)
Titanium alloys were developed as an alternative to stainless steels and have been extensively used as biomaterials ever since. One of these alloys is Ti-13Nb-13Zr (TNZ), a near-beta phase alloy containing elements with ...
Oxygen mobility and structural phase transformation in Bi2Sr2CaCu2O8+delta measured by anelastic spectroscopy
(Elsevier B.V., 2004-08-01)
One of the most studied ceramic superconductors for application has been, undoubtedly, Bi2Sr2CaCu2O8+delta. Although being a multiphasic material, it has proved to have great advantages compared to other ceramic systems. ...
