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 ...

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 ...

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 ...

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 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 ...

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 ...

Polymers are chemical compounds of high molecular weight (on the order 1000-10,000.000), named macromolecule. They are formed by the repetition of a basic unit called mere whose parameter . n is defined by the degree of ...
