Modeling two-phase ferroelectric composites by sequential laminates
(IOP Publishing, 2014-02)
Theoretical estimates are given for the overall dissipative response of two-phase ferroelectric composites with complex particulate microstructures under arbitrary loading histories. The ferroelectric behavior of the ...
EXAFS and Raman spectroscopy study of binary indium fluoride glasses
Extended X-ray absorption fine spectroscopy (EXAFS) and Raman scattering studies of InF3-BaF2 and InF3-SrF2 binary glasses are reported. For all compositions, the local structure of the glasses is built with InF6 units. ...
Processing, compatibilization and properties of ternary composites of Mater-Bi with polyolefins and hemp fibres
Ternary composites of a biodegradable thermoplastic matrix, Mater-Bi (MB), with various polyolefins (PP, HDPE and PS) and hemp fibres (H) were obtained by melt mixing and characterized by SEM, OM, DSC, TGA and tensile ...
OBTAINMENT OF HYBRID COMPOSITES BASED ON HYDROGEL AND PORTLAND CEMENT
(Soc Brasileira Quimica, 2016-02-01)
In this study, a novel hybrid composite based on biodegradable hydrogel and Portland cement with promising technological properties was reported. In the first step, a full 2(3) with central point factorial design was ...
Development of alpha-SiAlON-SiC ceramic composites by liquid phase sintering
(Elsevier B.V., 2007-01-01)
In this work, in situ alpha-SiAlON-SiC ceramic composites were obtained,by, liquid phase sintering, using SiC as reinforcement. Different beta-SiC powder contents (0-20 wt.%), were added to Si3N4-AlN-RE2O3. powder mixtures, ...
Physical properties of self-polarized PZT thin films at compositions around the morphotropic phase boundary
(Trans Tech Publications Ltd, 2014-01-01)
The physical properties of self-polarized PbZr1-xTixO3 thin films with no preferential orientation in a range of compositions 0.46 <= x <= 0.50 were investigated. Structural analysis revealed the coexistence of ...
Phase equilibrium and structure formation in gold nanoparticles - Nematic liquid crystal composites: Experiments and theory
(Royal Society of Chemistry, 2012-03)
A theoretical and experimental study of mixtures of a calamitic nematic liquid crystal and gold nanoparticles capped with mixed monolayers (alkylic + mesogenic ligands) is presented. The effect of the ligand monolayer ...
Higher dietary quality and muscle mass decrease the odds of low phase angle in bioelectrical impedance analysis in Brazilian individuals
Aim: Phase angle is a bioimpedance parameter that is suggested as an indicator of cellular death and membrane integrity. Studies have shown an association between phase angle and nutritional status in many diseases, but ...
