Witryna23 wrz 2008 · First-principles density-functional theory calculations for C solution enthalpies, ${H}^{\\text{sol}}$, and diffusion activation enthalpies, ${H}^{\\text{diff}}$, in body-centered-cubic Fe and Cr are presented. The results for C in Fe compare well with experiments, provided that the effect of magnetic disordering is accounted for. … WitrynaThere are three parts of this guideline: the evaluation of the toxicity data for potential elemental impurities; the establishment of a Permitted Daily Exposure (PDE) for each element of toxicological concern; and application of a risk- based approach to control elemental impurities in drug products.

Witryna23 lut 2024 · It is found that electronic temperature (T e) and chemical potential (μ) decrease faster with the increase in the Cr doping concentration. Similarly, the lifetime (τ) of the excited electrons also decreases with more Cr doped into Bi 2 Se 3. The results suggest a mechanism of impurity band-assisted carrier relaxation, where the … WitrynaImpurity standards; Nitrosamines; Pharmacopoeial standards; European Pharmacopoeia (Ph. Eur.)
