Analysis of nonisothermal sintering of zinc-titanate ceramics doped with MgO
The aim of this work is to analyze nonisothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO 2, and MgO (0, 1.25, and 2.5%) are mechanically activated for 15 ...
Sintering of mechanically activated Zno-TiO 2 powders
Zinc oxide and titanium dioxide powders mixed in an equimolar ratio are mechanically activated in a planetary ball mill and sintered under nonisothermal and isothermal conditions. Nonisothermal sintering is studied using ...
Poly(DL-lactide-co-glycolide) nanospheres for the sustained release of folic acid
(American Scientific Publishers, 2008)
Biodegradable polymers have become the materials of choice for a variety of biomedical applications. In particular, poly(DL-lactide-co-glycolide) nanoparticles have been studied as a material for drug delivery with the ...

Structural and electrical properties of the 2Bi2O3·3ZrO2 system
(Journal of Solid State Chemistry, 2008)
Powder mixtures of α-Bi2O3 (bismite) and monoclinic m-ZrO2 (baddeleyite) in the molar ratio 2:3 were mechanochemically and thermally treated with the goal to examine the phases, which may appear during such procedures. The ...
Biodegradable composites based on nanocrystalline calcium phosphate and bioresorbable polymers
(Taylor & Francis, 2008)
Nanocrystalline calcium phosphates (NC CP) are suitable for the synthesis of CP/bioresorbable polymer composite biomaterials for the application in bone engineering. There are different forms of NC CP/ bioresorbable polymers ...
Mechanochemical synthesis of nanocrystalline titanium monoxide
Nanocrystalline cubic titanium monoxide, TiOx (0.92 < x < 1.19), with mean crystallite size of ≈ 6 nm, was synthesized by mechanochemical treatment of Ti and TiO2 (rutile) powder mixtures with molar ratios of 1:1, ...
LaMO3 (M = Mg, Ti, Fe) perovskite type oxides: Preparation, characterization and catalytic properties in methane deep oxidation
Two new series of perovskite-type oxides LaMO3 (M = Mg, Ti, Fe) with different ratio Mg/Fe (MF) and Ti/Fe (TF) in the B cation site were prepared by annealing the precursor, obtained by the mechanochemical activation (MCA) ...
