Coffee-based colloids for direct solar absorption

Solar energy is one of the most promising resources to help reduce fossil fuel consumption and mitigate greenhouse gas emissions to power a sustainable future. Devices presently in use to convert solar energy into thermal ...

An artificial sunflower that bends toward the sun

A team of researchers from the University of California and Arizona State University has found a way to create a material that demonstrates tropistic behavior. In their paper published in the journal Nature Nanotechnology, ...

Porous polymer coatings dynamically control light and heat

Buildings devote more than 30% of their energy use to heating, cooling, and lighting systems. Passive designs such as cool roof paints have gone a long way toward reducing this usage, and its impact on the environment and ...

Getting more heat out of sunlight

A newly developed material that is so perfectly transparent you can barely see it could unlock many new uses for solar heat. It generates much higher temperatures than conventional solar collectors do—enough to be used ...
