How much would you bet these people have posters of Che and Marx on their walls?
“Join us to demand from ASU that these demands be met to protect students from a violent, blood-thirsty murderer.” “Even with a not-guilty verdict from a ‘flawed’ justice system – Kyle Rittenhouse is still guilty to his victims and the families of those victims,” the groups concluded. The Co tracer self-diffusion coefficients in single crystals are nearly identical to those in polycrystalline Co 1-xO.- Students for Socialism ASU 🚩 November 26, 2021 Comparison with thermogravimetric and electrical conductivity measurements confirms that the defects responsible for Co diffusion in the range of temperature and p/sub O 2 of this investigation are singly ionized cobalt vacancies. Measurements on crystals having deviations between 0.002 and 0.008 at 1150☌ showed the diffusion coefficient to depend on p O2 as D = 9.74 x 10 -9 p/sub O 2//sup 1/(3.59)/ cm 2/s, where p/sub O 2/ varied between 10 -2.5 and 10 -0.25 atm. This activation energy is in agreement with measurements made in air, if proper compensation is made for the effect of variation in more » stoichiometry. Measurements at x = 0.005 in Co 1-xO showed the Co tracer self-diffusion coefficient to be D = 3.88 x 10 -4 exp (-31600 ± 2400/RT) cm 2/s between 10☌. The arc-transfer technique of crystal growth was found to produce crystal of Co 1-xO of essentially the same purity as the starting Co rod, and the quality was comparable to commercially available crystals grown by Verneuil process. Tracer self-diffusion coefficients were measured as functions of temperature and deviations from stoichiometry.
