In the background is a thin tower that samples isoprene and collects wind measurements. In the foreground is a shed that houses the instrument that determines the concentration of the collected isoprene.

The technology uses new types of light-sensitive dyes to collect solar energy. Aqua-Yield has raised $23 million to advance a nanoparticle-based liquid that it touts as making fertilizers more efficient. The company says its additive can reduce fertilizer use by 25% by increasing how much plants absorb.

That is, where can our collective expertise and efforts have the most significant impact? We must focus our efforts there. The global pandemic has demonstrated unambiguously the critical importance of performing and publishing rigorous scientific work, educating students, and communicating science to elected officials and other members of the general public.

Our collective vision is also my vision. My focus is your focus on the following: Public image of chemistry. As we know, the public sometimes fears our data and often does not appreciate the benefits of chemical developments. Politicians withhold funds for research. Employers move jobs to places more favorable for profits.

So there is this wonderful collection of innovation. It’s hard for me to think of a sector that doesn’t get touched by green chemistry. You recently took on a formal adviser role at Air Company, which is making ethanol from carbon dioxide. How does a new chemical route to vodka embody green chemistry?

The data collected from those models could help researchers invent novel fuel sources and design new climate-resilient materials while providing scientists with new insights into chemical theory. “We’re at a point where we can start really asking questions about what is it that’s missing in our theoretical methods or models that would get us closer to what an experiment is telling us is real?”
