Numerical calculations are presented to show the influence of pressure and inductance on the vertical stability of shaped tokamaks. High values of epsilon beta(p) improve the vertical stability of dee shaped tokamaks but are destabilizing for an inverse de ...
Forward biasing of transparent nanocryst. TiO2 (anatase) films in lithium ion-contg. org. electrolytes leads to rapid and reversible coloration due to electron accumulation and Li+ intercalation in the anatase lattice. Absorption of >90% light throughout t ...
Especially when a three-phase or single-phase circuit contains at least one capacitor and one saturable inductance, the waveform of the periodic voltages and currents in this circuit can reach several different values (depending on the initial conditions) ...
Role of Pt and SRO electrodes in polarization fatigue of PLZT film ferroelectric capacitors is studied. We show that asymmetrical Pt/SRO/PLZT/Pt structure exhibits unusual dependence of the endurance of switching polarization on the driving ac electric fie ...
A new process for the production of metal matrix composites, whereby molten metal is forced into the interstices of a fibrous preform using electromagnetic body forces, is presented. These forces are created by subjecting the molten matrix to a concentrate ...
In the search for a good DSA-type O2-evolving electrode, the influence of the base metal (titanium, tantalum, zirconium, niobium and some of their alloys) on the performance of IrO2-Ta2O5 coated electrodes, was investigated. The thermal behavior and oxygen ...
Shaft systems of large turbine-generators can be subjected to high torsional stresses due to subsynchronous resonance especially in networks with capacitor- compensated lines. A second benchmark model for computer simulation of this phenomena has been prop ...
A simple and reliable method which allows one to distinguish between the two major microscopic scenarios for the suppression of the switching polarization (P-r(s)), i.e., pinning of ferroelectric domain walls (DWs) through the Pb(Zr,Ti)O-3 film (PZT) (bulk ...
