Study of timber and concrete with rubber waste composite beams applied to bridges
In order to overcome the hydrographic network, the landforms, and the most different types of barriers, many timber bridges were constructed around the world, especially in secondary roads where the raw materials (wood) ...
Piezoelectric composite film for acoustic emission detection
The continuous technological advances require materials with properties that conventional material cannot display. Material property combinations are being the focus to the development of composite materials, which are ...
Sustainability Ranking for Cuban Tourist Destinations Based on Composite Indexes
(Springer Netherlands, 2015-09-29)
Tourism sustainability evaluation has become an important issue in the development of this economic industry due to its dependence on natural environment quality and social acceptance. The study shows different ways to ...
Nanostructured TiO2-based composites for light absorption
(Trans Tech Publications Ltd, 2014-01-01)
Metal oxidenanocomposites were prepared by two different routes: polyol and sol-gel. Characterization by X ray diffraction showed that the first processproducesdirectly a two-phase material, while the sol-gelpowder never ...
Structural and dielectric properties of polyvinyl alcohol/barium zirconium titanate polymer-ceramic composite
The polyvinyl alcohol (PVA)/barium zirconium titanate Ba[Zr0.1Ti0.9]O3 (BZT) polymer-ceramic composites with different volume percentage are obtained from solution mixing and hot-pressing method. Their structural and ...
