内容摘要:
Impurity is by no means the most pleasant word one can find in a dictionary. As a discipline that relies on pure specimens to establish fundamental principles, mechanisms, and standards, chemistry does not particularly welcome impurities either. After all, chemistry develops over time as various purification techniques evolve. However, impurities have been playing an important role, occasionally indispensable, in advancing chemistry, technology, and even everyone’s everyday life. This presentation details selected intertwining stories between impurities and ever-curious human beings, including the multi-faced role of impurities in several historical moments of chemical discovery and the potential pitfalls they can bring.
