original: A material such as gold, which is chemically inert at normal scales, can serve as a potent chemical catalyst at nanoscales.
simplifications: Gold is chemically inactive on normal scales, but a potent chemical stimulant at nanoscale Materials like gold are chemically inactive at normal scales and can serve as chemical catalyst at nanoscales. Gold can serve as a strong chemical catalyst at nanoscales. Gold is chemically inactive at normal scales. A material such as gold is chemically inert at normal scales. However, it can be a strong chemical catalyst at nanoscales. A material like gold, which is chemically inert at normal scales, can be a strong chemical catalyst at nanoscales. Materials that are not active at normal scales can be strong agents of change at nanoscales. Gold, is chemically inert at normal scales, But is a potent chemical catalyst at nanoscales. Gold (chemically inactive normally), can be a powerful chemical starter at nanoscales. A material like those of gold, which is chemically inert in normal scales, can serve as a potent chemical catalyst in nanoscales. A material such as gold, which is chemically inactive at normal scales, can serve as a strong chemical catalyst at nanoscales.
