Short time scale pulse stability of the Crab pulsar in the optical band Abstract The fine structure and the variations of the optical pulse shape and phase of the Crab pulsar are studied on various time scales. The observations have been carried out on 4-m William Hershel and 6-m BTA telescopes with APD photon counter, photomultiplier based 4-channel photometer and PSD based panoramic spectroph...

Y2O3-stabilized ZrO2 (YSZ) ceramics have been used for various engineering applications or as a solid electrolyte in oxygen sensors and fuel cells. The performance YSZ strongly depends on the microstructure which is directly determined by characteristic of raw powder. In this paper, synthetic methods powder its starting material are first overviewed, then formation mechanism explained, focusing...
