The changes on microstructure and electrical properties of Bi:2223/Ag composite as a function of the granulation and the content of the added silver powder
(Trans Tech Publications Ltd, 2005-12-01)
The Bi-Sr-Ca-Cu-O system has been one of the most studied superconducting ceramic materials for industry applications. The most of the studies with this aim are on silver/ceramic composites, due to the benefits and great ...
Metallic powder injection molding using low pressure
(Elsevier B.V., 2014)
Powder processing and In Vivo evaluation of a titanium porous coating implant
The processing of titanium porous coatings using powder metallurgy technique to achieve a porous structure that allows osseointegration with bone tissue was discussed. The porous microstructure exhibited micropores and ...
Elaboration of boehmite nano-powders by spray-pyrolysis
(Elsevier B.V. Sa, 2009-03-05)
Boehmite (gamma-AlOOH) synthesis have been investigated using a spray pyrolysis (SP) device starting from a stable sol of Al-tri-sec-butoxide peptized by nitric acid. Free spherical particles from 100 to 500 nm have been ...
Seed phytate and protein content in beans depending on the application of basalt powder
(UNIV ESTADUAL MARINGA, PRO-REITORIA PESQUISA POS-GRADUACAO, 2011)
Seed phytate and protein content in beans depending on the application of basalt powder. The content of phytate in the grains is correlated with the supply of phosphorus to the plant, but there is a lack of knowledge as ...
Porous titanium scaffolds produced by powder metallurgy for biomedical applications
Porous titanium scaffolds are promising materials for biomedical applications such as prosthetic anchors, fillers and bone reconstruction. This study evaluated the bone/titanium interface of scaffolds with interconnected ...
Lanthanum doped BiFeO3 powders: Syntheses and characterization
(Elsevier B.V. Sa, 2010-07-02)
A soft chemistry route was employed to fabricate single-phase lanthanum modified BiFeO3 (BFO) powders. Effects of lanthanum concentration on the phase formation, grain size and morphologies of BFO powders were systematically ...
