Novel Catalyst Helps Turn Carbon Dioxide Into Fuel

Artificial photosynthesis is the process of converting carbon dioxide gas into useful carbon-based chemicals - most notably fuel or other compounds usually derived from petroleum - as an alternative to extracting them from biomass. An Illinois research team has produced a catalyst that improves the process.

Driving Growth and Innovation With Sustainable Design

Sustainable design — a dedicated effort to create products in a manner that minimizes their negative impact on the environment, making them more economically viable, socially acceptable, and ecologically tenable — is often misunderstood. In the past, many manufacturers viewed efforts to become more environmentally friendly as expenses rather than opportunities.
