Structure and electrical properties of single-phase cobalt manganese oxide spinels Mn3xCoxO4 sintered classically and by spark plasma sintering(SPS) [PDF]

open access: yes, 2009
Cobalt manganese oxide spinels Mn3 xCoxO4 (with 0.98pxp3) were prepared by the thermal decomposition in air of oxalate precursors. The influence of the thermal treatments on the structure of these materials is emphasized.

Nonequilibrium Kinetic Modeling of Sintering of a Layer of Dispersed Nanocrystals

open access: yes, 2014
We report a kinetic Monte Carlo modeling study of nanocrystal layer sintering. Features that are of interest for the dynamics of the layer as a whole, especially the morphology of the evolving structure, are considered.

Controlling internal barrier in low loss BaTiO3 supercapacitors [PDF]

open access: yes, 2009
Supercapacitor behavior has been reported in a number of oxides including reduced BaTiO3 ferroelectric ceramics. These so-called giant properties are however not easily controlled. We show here that the continuous coating of individual BaTiO3 grains by a

Structural analysis and sintering aids effects in La2Ce2O7 proton conductors [PDF]

open access: yes, 2018
Global warming is an important problem that has to be solved without delay. The development of environmental-friendly energy technology is needed to deal with this issue. Solid Oxide Fuel Cells (SOFC) technology has been proposed as a real alternative to

The effect of processing route on properties of HfNbTaTiZr high entropy alloy [PDF]

open access: yes, 2019
High entropy alloys (HEA) have been one of the most attractive groups of materials for researchers in the last several years. Since HEAs are potential candidates for many (e.g., refractory, cryogenic, medical) applications, their properties are studied ...

Low-Temperature Rapid Synthesis and Superconductivity of Fe-Based Oxypnictide Superconductors

open access: yes, 2010
we were able to develop a novel method to synthesize Fe-based oxypnictide superconductors. By using LnAs and FeO as the starting materials and a ball-milling process prior to solid-state sintering, Tc as high as 50.7 K was obtained with the sample of Sm ...

Morphology, structure, optical, and electrical properties of AgSbO₃ [PDF]

open access: yes, 2016
The morphology of defect pyrochlore-type, AgSbO₃ microparticle/nanoparticles obtained via solid state reaction evolve from irregular to Fullerene-like polyhedra before finally decomposing into metal-organic framework-5 like particles with increase in ...

Solid Freeform Fabrication of Functional Silicon Nitride Ceramics by Laminated Object Manufacturing 1 [PDF]

open access: yes, 2000
The processing of silicon nitride (Si3N4) structural ceramics by Laminated Object Manufacturing (LOM) using ceramic tape preforms was investigated. The key processing stages involved green shape formation (which used the LOM process), followed by the ...
