BONE REGENERATION USING beta-TRICALCIUM PHOSPHATE IN A CALCIUM SULFATE MATRIX
(2009)The aim of the study was the histomorphometric comparison of the osteogenic potential of beta-tricalcium phosphate (beta-TCP) alone or in a calcium sulfate matrix. Three round defects, 10 mm (diameter) X 5 mm (depth), were ... -
The effect of co-dopant addition on the properties of Ln(0.2)Ce(0.8)O(2-delta) (Ln = Gd, Sm, La) solid-state electrolyte
(2008)The present work aims at the investigation of Ln(0.2)Ce(0.8)O(2-delta) (where Ln = Sm, La, Gd) structural and electrical properties when in the Ln sub-lattice, Ba2+ and Sr2+ with ionic radii 1.42 and 1.26 angstrom, ... -
Indentation of plastically graded substrates by sharp indentors
(2002)The present paper investigates the indentation of plastically graded substrates by sharp indentors. Contact analysis of plastically graded surfaces can be particularly useful in the design of load-bearing devices such as ... -
Influence of Cu on the properties of gadolinium-doped barium cerate
(2008)In the present work the effect of copper oxide addition on the densification behavior and electrical conductivity of BaCe1-xGdxO3-delta (BCG) type ceramics is investigated. Small addition (1 mol%) of this sintering additive ... -
Investigation of the structural and electrical properties of Co-doped BaCe0.9Gd0.1O3-delta
(2011)In the present work the effect of cobalt oxide addition on the density and on the electrical properties of gadolinium-doped barium cerate is investigated. A series of BaCe0.9-xGd0.1CoxO3-delta (x = 0.00, 0.01, 0.03, 0.05, ... -
Sulfur and carbon tolerance of BaCeO3-BaZrO3 proton-conducting materials
(2015)In the present work, BaCe0.8-xZrxY0.2O3-delta-based ceramic samples (BCZYx) are prepared and their chemical stability in corrosive atmospheres containing high concentrations of H2O, CO2 and H2S is investigated. Based on ...
