β- TCP produced through the starch consolidation technique
(2016-01-01)
Synthetic materials based on calcium such as hydroxyapatite and beta-TCP are one of the main bone substitutes because of their biocompatibility. The starch consolidation is a simple and low cost technique which is based ...
Vapor intrusion in soils with multimodal pore-size distribution
(2016-09-12)
The Johnson and Ettinger [1] model and its extensions are at this time the most widely used algorithms for estimating subsurface vapor intrusion into buildings (API [2]). The functions which describe capillary pressure ...
Acoustic Scattering By Finite Poroelastic Plates

Filtration Gas Combustion in a Porous Ceramic Annular Burner for Thermoelectric Power Conversion
(2016)
mixtures in a porous media burner is performed using a novelty
geometry, cylindrical annular space. The combustion process
takes place in the porous annular space located between two
pipes, which are filled with alumina ...
Surface study of vitreous carbon obtained from glassy carbon powder
(2012-05-22)
This work presents a surface study of monolithic vitreous (or glassy) carbon - MVC - obtained from vitreous carbon powder. Defective MVC pieces are crushed in a ball mill and size classified by sifting. The MVC powder is ...
Use of silica fume and nano-silica in mortars attacked by acids present in pig manure
(2018-01-01)
Pig houses provide a highly aggressive environment to concrete structures. The chemical aggressiveness generated by pig manure may cause wear, loss in strength and premature damage to floors, leading to animal hoof diseases. ...
Synthetic benchmark for the computation of equivalent properties in coupled flow and geomechanics conditions for a fractured carbonate rock
(2018-01-01)
In this work, we report on a successful benchmark program motivated by the development of robust hydro-mechanical coupled models capable of providing accurate equivalent properties, such as permeability and porosity, in ...
Vegetable fiber as reinforcing elements for cement based composite in housing applications - A Brazilian experience
(2018-02-14)
Vegetable fibers are a hierarchical structure material in the macro, micro and nanometric scales that have been used as reinforcement in cementitious materials. In nanoscale, the nanofibrillated cellulose has the advantage ...
Desenvolvimento do processo de soldagem laser pulsado Nd:YAG para lâminas de 100 μm de espessura de AISI 316L
(2010-12-01)
Experimental investigations were carried out using a pulsed neodymium: yttrium aluminum garnet laser welding to examine the influence of the pulse energy in the AISI 316L thin foil welding with 100 μm thickness, employed ...
Microstructure and Thermal Conductivity of Porous Al2 O3-ZrO2 Ceramics
(2015-01-01)
The improvement on the development of porous ceramic materials has leaded to new technologies in thermal insulation, for example, composite materials for better performance of pressure vessels in rocket engines. Within ...
