Plasticizers … WitrynaImpurities with larger differences in valence from the host typically produce states which are much further from the band edges – called deep levels. These take more thermal energy to release carriers, so are less important in determining carrier concentrations. However, they can trap free carriers and allow them to interact with carriers

Witryna10 lip 2024 · Because this index is used in binary target variables (0,1), a gini index of 0.5 is the least pure score possible. Half is one type and half is the other. Dividing gini scores by 0.5 can help intuitively understand what the score represents. 0.5/0.5 = 1, meaning the grouping is as impure as possible (in a group with just 2 outcomes). Witrynaso the impurity profile of an active substance whose manufacturing process involve s fermentation may be more complex and less predictable than that of a purely synthetic product. For this reason fermentation products and semi-synthetic substances are not included in the scope of the ICH Q3 and hazard communication standard poster
