| Recent research has discovered that a semiconductor can be made magnetic by doping it with an impurity. |
| In reversed-polarity mode, they also observed a new peak similar to that of maleate, which they later attributed to the impurity fumarate. |
| Silicon, after iron, is the highest impurity level in electrolytic commercial aluminum. |
| Women folk of the village have to walk uphill and down dale to fetch a pail of water irrespective of its purity or impurity. |
| In general, it is recommended that a separate crucible be reserved for melting because of the low impurity limits specified for the alloys. |
| Consequently, the material is embrittled by impurity segregation to interfacial boundaries. |
