Synthesis and Properties of Lead Magnesium Niobate Zirconate
Two materials were prepared with composition PbMg0.3Nb0.6Zr0.1O3 (PMNZ/10) and PbMg0.32Nb0.65Zr0.03O3 (PMNZ/3). Slight modifications in lead oxide content of these materials were made to study its influence on the sintering properties. The stoichiometric PMNZ/3 gave the best results. It has a sintering temperature as low as 900°C and a relative dielectric constant of 10 000 at room temperature.
متن کاملPMN-PT (lead magnesium niobate-lead titanate) piezoelectric material micromachining by excimer laser ablation and dry etching (DRIE)
In the attempt to find the appropriate micromanufacturing technology of PMN-PT (lead magnesium niobate–lead titanate) piezo material, whose MEMS-related applications look promising, two methods are investigated: excimer laser ablation (using KrF gas) and inductively coupled plasma (ICP) dry etching, also known as DRIE (using Ar/C4F8 gases). The paper quantitatively reports the optimal parameter...
متن کاملThe Isoelectric Point of Adsorbed Hemo- Globin*
It is well established that various proteins, as gelatin and albumin, can be adsorbed on various adsorbents so that the proteincoated particle of adsorbent behaves electrophoretically as a particle of protein (Loeb, 1923; Freundlich and Abramson, 1928). Dummett and Bowden (1933) have recently reported, however, that the behavior of adsorbed hemoglobin varies with the adsorbent surface. Thus, wh...
متن کاملDielectric phase-transition and polarization studies in stepped and compositionally graded lead magnesium niobate–lead titanate relaxor thin films
Ferroelectric properties of chemically heterogeneous multilayers and graded composition thin films of 1−x Pb Mg1/3Nb2/3 O3–xPbTiO3, a well-known relaxor, were prepared using a multitarget pulsed laser ablation system. Target materials with different values of x 0.0, 0.1, 0.2, and 0.3 were used for ablation growth. Films with sharp interfaces and graded interfaces were prepared and were characte...
متن کاملThe isoelectric point of bacterial cells.
This study was undertaken to compare the isoelectric points of gram positive and gram negative bacterial cells by the method of microelectrophoresis. Within recent years a number of workers have referred to differences in the isoelectric point of the gram positive and the gram negative groups of bacteria. This concept arose from the studies of Stearn and Steam (1924, 1925, 1928), Tolstoouhov (1...
