A hydrothermal method for preparing thin films of crystalline PZT was developed by controlling the rates of nucleation and crystal growth. This method consisted of two steps of hydrothermal reaction. The first step (nucleation process) was that in which the TiO 2 substrate reacted with the mixed solution of Pb and Zr…

Over the past decade and a half, analyses of the dynamics of fluids containing moving contact lines have specified hydrodynamic models of the fluids in a rather small region surrounding the contact lines (referred to as the inner region) which necessarily differ from the usual model. If this were not done, a singulari…

The switching behavior of ferroelectric capacitors experiencing arbitrary time-dependent electric fields and arbitrary initial conditions is investigated both theoretically and experimentally. A general approach for modeling incomplete dipole switching in ferroelectric capacitors is used to derive equations describing…

The addition of a tertiary radical to an electron-deficient alkene proves to be the decisve step in the synthesis of the four-directional cascade polymers 1 and 2, which have no heteroatoms in the initial core, in the branching centers, or in the repeat units. Only the periphery is highly fuctionalized.

An efficient procedure for calculating the contribution of the thermal diffuse scattering to the absorptive form factor is outlined. For an isotropic Einstein model all integrations could be performed analytically by using suitable functions to fit the elastic electron scattering amplitudes. The result is cast into a…

Steel in contact with fresh concrete is covered by a layer of passivating oxydes due to the alkaline nature of the pore solution. The presence of oxygen plays an important role in this passivation process as well as in the corrosión one when is developped due to the ingress of aggressives, such as, chloride ions. In t…
