In figure 5 calcium titanate has been doped with aluminum and the rare earth (RE) has been varied.
She was doped until she was deeply asleep and would feel little, if anything, of what went on during her labour.
This is known to be the optimum conditions for the doped alumina.
The very recent progress in fabrication of high-Q polymer microcavities doped by semiconductor QDs actually initiates cavity quantum electrodynamics.
A paper describing an experimental and modeling study of low pressure sulfur and nitrogen doped premixed methane flames has been published.
