We study the expectancy of large glitches (DELTAOMEGA/OMEGA > 10(-7)) from a sample of 430 pulsars other than the Vela pulsar. The pulsars in this sample have exhibited 19 large glitches. We assume that all pulsars experience such glitches, with rates that depend on the pulsar's rotation rate OMEGA and spin-down rate OMEGA, and on the glitch model. We use the core-quake model, and two variants of the superfluid vortex unpinning model, and choose model parameters such that the observed number of glitches is ...
Synthesis, structural characterization and chemistry of tribenzoheterotriquinane based molecular structures.
Kepil, Dilay; Günbaş, Emrullah Görkem; Department of Chemistry (2020)
The synthesis of heteroatom containing derivatives of triquinane structure by the Mascal group represents an important development in the field of fundamental organic chemistry. Some derivatives of hererotriquinane structures showed unusual reactivity and structure properties. For example, oxonium ions are known as fleeting intermediates in certain reaction mechanisms. However, oxatriquinane, the oxygen containing analogue of heterotriquinane family, shows extreme stability. It can be chromatographed and su...

Quantitative atom-resolved force gradient imaging using noncontact atomic force microscopy
Oral, Ahmet; ÖZER, HAKAN ÖZGÜR; HOFFMANN, PM; PETHICA, JB (2001-09-17)
Quantitative force gradient images are obtained using a sub-angstrom amplitude, off-resonance lever oscillation method during scanning tunneling microscopy imaging. We report the direct observation of short-range bonds, and the measured short-range force interaction agrees well in magnitude and length scale with theoretical predictions for single bonds. Atomic resolution is shown to be associated with the presence of a prominent short-range contribution to the total force interaction. It is shown that the b...
