Modeling the crystallographic structure of Ho(Ni,Co,Mn)O3±δ perovskite-type manganite
(2012)
Crystallographic and microstructural properties of Ho(Ni,Co,Mn)O3± perovskite-type multiferroic material are reported. Samples were synthesized with a modified polymeric precursor method. The synchrotron X-ray powder ...
Carbon nanotubes/polyamide 6.6 nanostructured composites crystallization kinetic study
(2013-08-01)
Compared with the traditional composites, the incorporation of carbon nanotubes into polymeric matrices can generate materials with superior properties, especially thermal, electrical and tribological properties. The aim ...
Intrinsic magnetic properties of BixCo2-xMnO 4 spinels obtained by short-time etching
(2013-08-01)
We report the structural and magnetic properties of Co2MnO 4, partially substituted by Bi at the octahedral site. Bismuth enhances ferromagnetism due to a decrease of the Co2+-Co2+ antiferromagnetic interactions and an ...
Effect of Eu substitution on the crystallographic and magnetic properties of the BiMn2O5 oxide obtained by urea combustion
(Elsevier B.V., 2014-09-01)
Polycrystalline oxide materials with nominal compositions BiMn2O5 and Bi0.9Eu0.1Mn2O5 were obtained by urea combustion. Crystallographic studies using X-ray diffraction and Rietveld Refinement techniques showed the formation ...
Synthesis of FeNi Alloy Nanomaterials by Proteic Sol-Gel Method: Crystallographic, Morphological, and Magnetic Properties
(Hindawi Publishing Corp, 2016-01-01)
Proteic Sol-Gel method was used for the synthesis of FeNi alloy at different temperature conditions and flow reduction. The solids were characterized by XRD, H-2-TPR, SEM, TEM, Mossbauer spectroscopy, and VSM. It was ...
Tribocorrosion behaviour of anodic treated titanium surfaces intended for dental implants
(2013-10-09)
Tribocorrosion plays an important role in the lifetime of metallic implants. Once implanted, biomaterials are subjected to micro-movements in aggressive biological fluids. Titanium is widely used as an implant material ...
Weak ferromagnetism above T-N in Gd2CuO4
(Elsevier Science BvAmsterdamHolanda, 2001)
Crystallographic Texture Evolution of a Zinc Sheet Subjected to Different Strain Paths
(Springer, 2017-03)
The use of zinc sheets has largely increased in the last years, fundamentally because of new tendencies in architecture and, at the same time, due to its excellent properties, as corrosion resistance under aggressive ...
Evolution of magnetic properties and crystallographic texture in electrical steel with large plastic deformation
(AMER INST PHYSICS, 2011)
Deformation leads to a hardening of steel due to an increase in the density of dislocations and a reduction in their mobility, giving rise to a state of elevated residual stresses in the crystal lattice. In the microstructure, ...
Crystallographic, dielectric and optical properties of SrBi2Ta2O9 thin films prepared by the polymeric precursor method
(Taylor & Francis Ltd, 2002-01-01)
Strontium bismuth tantalate thin films were prepared on several substrates (platinized silicon (PvTi/SiO2/Si), n-type (100)-oriented and p-type (111)-oriented silicon wafers, and fused silica) by the solution deposition ...
