Stiffness of lipid monolayers with phase coexistence
(American Chemical Society, 2013-08)
The surface dilational modulus (or compressibility modulus) has been previously studied for monolayers composed of pure materials, where a jump in this modulus was related with the onset of percolation as a result of the ...
Mechanism of phase formation in Pb(ZrxTi1-x)O3 synthesized by a partial oxalate method
(1996-06-01)
The phase formation mechanism, as well as the morphotropic phase boundary, of lead zirconate titanate (PZT) processed by a partial oxalate method was investigated by simultaneous thermal analysis (TG-DTA) and by qualitative ...
Attainability of the Hashin–Shtrikman bounds for two-phase well-ordered composites with a nonlinear phase
(Elsevier Masson, 2013-10)
The Hashin–Shtrikman (HS) bounds for two-phase well-ordered composites are known to be attained by certain sequentially laminated constructions when the constituent phases exhibit a linear behavior. This implies that the ...
Structural characterization of organometallic-derived 9.5/65/35 PLZT ceramics
(Elsevier B.V., 2001-02-15)
This study consisted of an investigation of the influence of powder preparation on the phase and chemical compositions and microstructure of 9.5/65/35 PLZT materials sintered in an oxygen atmosphere. The powders with the ...
Synergistic effects on polyurethane/lead zirconate titanate/carbon black three-phase composites
(2017-07-01)
Synergistic processes in hybrid composites have frequently been described in the literature over the past few years, opening doors to new studies and applications for this type of material. In this study, three-phase ...
Chiral separation of aryloxyphenoxy-propionate herbicides in a permethyl-β-cyclodextrin based column. Influence of temperature and mobile phase composition on enantioselectivity
(Wiley VCH Verlag, 2017-08)
We used a permethyl-β-cyclodextrin chiral stationary phase under reversed-phase conditions for the chiral separation of four aryloxyphenoxy-propionate herbicides (fenoxaprop-p-ethyl, quizalofop-p-ethyl and tefuryl, and ...
PZT–NZF/CF ferrite flexible thick films: Structural, dielectric, ferroelectric, and magnetic characterization
(2019-12-01)
The preparation and properties of thick flexible three-phase composite films based on lead zirconium titanate (PZT) and various ferrites (nickel zinc ferrite (NZF) and cobalt ferrite (CF)) were reported in this study. ...
Corrosion and tribocorrosion behaviour of Al-Si-Cu-Mg alloy and its composites reinforced with B4C particles in 0.05M NaCl solution
(2013-08-30)
The corrosion behaviour of metal matrix composites (MMCs) is strictly linked with the presence of heterogeneities such as reinforcement phase, microcrevices, porosity, secondary phase precipitates, and interaction products. ...
Electroactive properties of flexible piezoelectric composites
(ABM, ABC, ABPol, 2001-07)
A flexible piezoelectric composite with 0-3 connectivity, made from Lead Zirconate Titanate (PZT) powder and vegetable-based polyurethane (PU), was doped with small amount of semiconductor powder. As a result a composite ...
Phase analysis of seeded and doped PbMg1/3Nb2/3O3 prepared by organic solution of citrates
(1996-07-01)
PbMg1/3Nb2/3O3 (PMN) prepared by organic solution of citrates was analyzed by the Rietveld method to determine the influence of seeds and dopants on the perovskite and pyrochlore phase formation. It was observed that ...
