Influence of the microstructure in the collapse of a residual clayey tropical soil
(SPRINGER HEIDELBERG, 2009)
A typical residual clayey soil originating from basalt in southern Brazil has been analyzed in order to assess the influence of wetting-induced deformation and microstructural features on the collapse behavior. Single and ...
Nanoporous carbon superstructures based on covalent bonding of porous fullerenes
Highly porous and mechanically stable nanostructures are of great interest for applications in selective membranes, adsorbents, catalysts and sensors. In this study, we use Density Functional Theory calculations and Molecular ...
Formation of zirconia foams using the thermostimulated sol-gel transition
(Elsevier B.V., 2014)
Development, characterization and clinical use of a biodegradable composite scaffold for bone engineering in oro-maxillo-facial surgery
(Landes Bioscience, 2010-07-01)
We have developed a biodegradable composite scaffold for bone tissue engineering applications with a pore size and interconnecting macroporosity similar to those of human trabecular bone. The scaffold is fabricated by a ...
In vitro and in vivo biological performance of porous Ti alloys prepared by powder metallurgy
Titanium (Ti) and Ti-6 Aluminium-4 Vanadium alloys are the most common materials in implants composition but β type alloys are promising biomaterials because they present better mechanical properties. Besides the composition ...
Catalytic coating synthesized onto cordierite monolith walls. Its application to diesel soot combustion
(Elsevier Science, 2012-12)
Co,Ba,K/ZrO2 coating onto a cordierite monolith was produced using a sequential process. The first step involved the formation of a ZrO2 layer using a colloidal suspension and the second, the incorporation of active metals. ...
Preparação de membranas poliméricas porosas a partir de técnicas de espumação com agentes físicos de expansão
(Universidade Federal de São CarlosUFSCarPrograma de Pós-graduação em Ciência e Engenharia de MateriaisCâmpus São Carlos, 2016-07-07)
The objective of this master’s thesis was to develop a process of manufacturing porous polymer membranes for microfiltration by a one-step foaming technique, using carbon dioxide (CO2) as physical blowing agent and ethanol ...
