Imagine a person on the ground guiding an airborne drone that harnesses its energy from a laser beam, eliminating the need for carrying a bulky onboard battery.
without heat or electricity, offering innovative possibilities for energy-efficient, wireless and remotely controlled systems. Its wide-ranging potential spans across diverse industries, including robotics, aerospace and biomedical devices.
The research contrasts with previous attempts involving delicate crystalline solids that changed shape through a photochemical reaction, but often cracked when exposed to light and were challenging to process into useful actuators. The Hayward's Lab innovative approach involves using arrays of tiny organic crystals within a polymer material that resembles a sponge due to its tiny holes. As the crystals grow within the micron-sized pores of the polymer, their durability and energy production upon light exposure are significantly enhanced. Their flexibility and ease of shaping make them highly versatile for a wide range of applications.
CU Boulder researchers also include lead author Wenwen Xu, a former postdoctoral researcher in Hayward's group, and Hantao Zhou , one of Hayward's graduate students.The work also involved collaborators at the University of California Riverside and Stanford University.

Researchers improve air pollution exposure models using artificial intelligence and mobility dataAmericans in the Northeast paid greater attention to air quality alerts this summer as wildfire smoke thickened skies with an orange-tinted haze. Smoke and other sources of air pollution contain tiny particles, called fine particulate matter (PM 2.5). Smaller than the width of a human hair, PM 2.5 pose health dangers when inhaled, especially to people with pre-existing heart and lung conditions.
