Matrix of fluorescent particles with pores that open and close — Sujit Datta’s research group received funding to develop leaf-inspired soft materials that someday could allow robots to efficiently transfer water and heat. Shown here are microscopic slices at different depths through a mesoporous thermo-responsive hydrogel that will form the basis of artificial leaf stomata that are programmed to dynamically open and close in response to sunlight or heat. Black circles show large voids in the hydrogel structure; white shows fluorescent particles embedded in the hydrogel matrix.

Artificial leaves, floating breakwaters and musical memories are among recipients of 2021 innovation grants
