Piezoelectric thick films based on Pb(Zr,Ti)O3 (PZT) were prepared on two types of LTCC tapes (Du Pont 951 and Electro Science Labs. 41020) and on relatively inert alumina substrates. The results obtained with the alumina were used as a reference. The microstructures of the cross-sections of the resistors were investigated using scanning electron microscopy (SEM) and energy-dispersive X-ray (EDS) analysis. The dielectric permittivities, dielectric losses, remanent polarisation, coercive field and piezoelectric ...

In recent years vanadium-doped hard coatings have become available as possible candidates for self-lubrication at high temperatures. Their low coefficient of friction has mainly been attributed to the formation of the V2O5 phase. However, the formation of vanadium oxides must be controlled by the out-diffusion of vanadium in order to achieve the combination of a low coefficient of friction and good mechanical properties for the protective coatings. In this work the application of a nanolayer of ...

We will present some experimental results that show why growth defects and other coating-surface irregularities must be considered in all the tribological tests of such coatings. All surface asperities, particularity the nodular defects, form the first contact spots between ...

${\text{Pr}}_{1\ensuremath{-}x}{\text{Ca}}_{x}{\text{MnO}}_{3}$ (PCMO, $x=0.3$) ceramic is a member of the manganite family that exhibits a colossal magnetoresistance. We report a comprehensive study of perovskite manganite PCMO $(x=0.3)$ ceramic with EPR, dielectric spectroscopy, and ac electrical conductivity. Activated-type temperature dependence of EPR linewidth is a strong signature for a hopping of Jahn-Teller polarons above $\ensuremath{\approx}150\text{ }\text{K}$.

Posterior capsule opacification (PCO) is the most common post-operative complication associated with cataract surgery and is mostly treated with Nd:YAG laser capsulotomy. Here, we demonstrate the use of high-resolution spectral-domain optical coherence tomography (OCT) as a technique for PCO analysis. Additionally, we evaluate the influence of PCO types and the distance between the intraocular lens (IOL) and the posterior capsule (PC), i.e., the IOL/PC distance, on the total-pulse energy required for ...

Recently it was reported that the thin film of 0.8Pb(Zr0.53Ti0.47)O3–0.2Pb(Fe2/3W1/3)O3 (0.8PZT–0.2PFW) has a new and very large magnetoelectric effect—switching from Pr to zero with applied magnetic field of less than a Tesla.

A Nd:YAG laser photodisruption is a well-established tool for intraocular surgery, such as treatment of posterior capsule opacification that affects the visual function. During the intraocular procedure, called laser capsulotomy, the excitation pulse is focused several times just behind the posterior capsule and intraocular lens to create the central opening in the opacified capsule. We built an in vitro experiment to (1) clarify the influence of the distance between the intraocular lens and the ...

We report a method for the one-step synthesis of a thin layer of anatase TiO2 on Ti6Al4V alloy for the improvement of short-term and long-term body responses. In particular, this method decreases the direct contact between bone tissue and metals, especially aluminium and vanadium, and improves bone osseointegration. The coating was prepared by hydrothermal synthesis in the presence of titanium ions. Morphology advantageous for bioactivity and photocatalytic properties were achieved by using the ...

Here, the stoichiometric ceramic was sintered to 97% of theoretical density at a temperature of 1000 °C, which is 200–300 °C lower than previously ...

The highest piezoelectric coefficient d 33 , coupling coefficients k p , k t , and mechanical quality factor Q m were achieved for ceramics poled at electric fields between 2 and 3.5 kV/mm, whereas the d 33 , k p , k t , and Q m of ceramics poled at higher electric fields, i.e., 4 and 4.5 kV/mm, were lower. The non-poled ceramics contained 86% of the ...

Abstract Thick film varistors based on the system ZnO–Bi 2 O 3 –Sb 2 O 3 have been prepared by screen printing technology on dense alumina substrates. Different processing strategies have been designed in order to control the excessive volatilization of Bi 2 O 3 in varistor films during the sintering, due to the high area–volume ratio, and as a means to improving their electrical response. Starting powders were selected and pre-treated in different ways to obtain different phases and control the ...

PZT thick films (PbZr0.53Ti0.47O3 with the addition of 6% PbO and 2% Pb5Ge3O11) with a low sintering temperature were printed and fired on LTCC substrates (951, Du Pont), covered with an alumina barrier layer. The electrical characteristics (remanent polarisation, coercive field, dielectric constant and dielectric loss) of these PZT thick films, together with sets prepared on “unprotected” LTCC substrates and on alumina substrates were compared. Whereas the electrical characteristics of the films on ...

In the present work we propose a simple, one-step hydrothermal process for the direct crystallisation of an anatase layer, up to 2 μm thick, and with high bonding strength, on a Ti6Al4V alloy without any surface pretreatment. The samples were processed at different pH values with or without the addition of TiO2 or Ti(OH)4, resulting in different morphologies of anatase crystals and different thicknesses of the oxide layer. The thickest, uniform, well-bonded nanocrystalline anatase layer was obtained ...

A linear space L of operators on a vector space X is called semitransitive if, given two nonzero vectors x, y in X, there exists an element A in L such that either y=Ax or x=Ay. In this paper we consider semitransitive spaces of operators on a finite dimensional vector space X over an algebraically closed field. In particular, we are interested in the existence of nontrivial invariant subspaces of X for a semitransitive space L. We are able to relate the existence of an invariant subspace for L ...

These "substrate-free", bending-type actuators were prepared by screen-printing the 65/35 PMN–PT and Pt thick-film pastes as the electrodes on alumina substrates. After this screen printing and the subsequent firing the 65/35 PMN–PT/Pt composites were peeled off from the substrates. Displacements of nearly 100 μm at 18 V were achieved for actuators with dimensions ...
