Synthesis and characterization of Al, Y, Co and Cr substituted ultrafine powder of NiFe2O4
(Materials Science Forum, 2004)
The ultrafine spinel NiFe1.9M0.1O4 powders (M=Al, Y, Cr, Fe) were synthesized by thermal decomposition of appropriate mixtures of complex compounds with acetylacetone - (2,4 pentadione) ligands ([M(AA)(x)]) at 500 degreesC. ...
Microstructure and hydrogen desorption in nanostructured MgH2-Fe
(Materials Science Forum, 2004)
Mg-based nanostructured hydrides have been synthesized by ball milling using two alternative approaches. The first is based on the reactive milling of Mg powders in H-2 atmosphere, while the second on the milling of ...
Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Materials Science Forum, 2004)
Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents ...
