From catalysts to anticancer agents, a promising star with much hidden potential.

I’m skilful and helpful, even if I do say so myself. As a catalyst, I help solve environmental issues and I’m even a basic ingredient in pharmaceuticals. Let’s sit down and talk next time, and I’ll tell you what a great help I am everywhere.
