of this diffusional process, it would be expected that the separation of two sub-grain and the formation of α/β interface can be completed by increasing the deformation time and thus the aspect ratio of α......
that, the clear solution was separated from the mixture using centrifuge separation and added into a cation exchange column (φ0.5 cm×15 cm, AG50W×8 (H+) 74-149 μm). The Rb and Sr were rinsed with a 1.75 mL..., RADOSAVLJEVIC-MIHAJLOVIC A S, KASIC V D.

activity of Pt catalysts for methanol oxidation. Another peak emerging in the reverse scan reflects the elimination of the residual carbonaceous species (e.g., CO) that are left in the forward scan. Thus the ratio of the forward peak current to the backward peak current (If/Ib) can be used to estimate the tolerance of Pt catalysts against CO poisoning [30, 31]. The If value of EEG-Pt-eg is ~292.4......
of one side goaf when mining. As the support range at the bottom of the TMR becomes smaller and the bed separation range becomes larger, the TMR is easy to break and settle suddenly in the mining process......
