Rb impurity's
WebJan 1, 1978 · The role of Rb + ions on defect formation in KBr has been studied. The impurity suppresses colorability due to X-raying at 6 K, but does not result in the formation of any centers characteristic to Rb + ions at this temperature. A new optical absorption band peaked at 3.19 eV is produced only by thermal annealing of irradiated KBr:Rb. WebDuring the synthesis of the bulk drug Raloxifene hydrochloride, eight impurities were observed, four of which were found to be new. All of the impurities were detected using the gradient high performance liquid chromatographic (HPLC) method, whose area percentages ranged from 0.05 to 0.1%. LCMS was performed to identify the mass number of these ...

WebDec 15, 2024 · Experiments on potassium and K-0.077 at.% Rb strained at 60 K indicate the presence of a new temperature-dependent scattering mechanism at T-0.25 K. We ascribe this to inelastic scattering of vibrating dislocations. At the same time the suppression of phonon drag at higher temperatures results in the emergence of the normal electron … WebAbstract. We report the progress on investigating the Bose polaron problem with a mixture of ultracold Bose-Bose mixture of 23 Na and 87 Rb atoms. We prepare the Bose polaron by immersing heavy 87 Rb impurities in the Bose-Einstein condensate of 23 Na. Using radio frequency spectroscopy, we investigate the polaron injection spectrum and its …
