007skaty Microscopic Shields and Magnetic Dust
Microscopic shields wash the stains away, and magnetic dust pulls the plastic out.
007skaty Developed in 2020, electrospun nanofiber membranes act as ultra-fine washing machine filters to block microplastics from entering municipal
007skaty Holographic light highlights self-cleaning titanium dioxide nanocoatings on a dark building facade
BETA
007skaty Deploy nano-filters to learn how advanced technologies capture microscopic dust.
Fun Fact
Smart sponges: The OHM sponge can absorb 30 times its weight in oil while completely repelling water, allowing it to be reused.
Glossary
nanoparticle (noun)
A microscopic particle of matter that has at least one dimension of less than 100 nanometers. In 2012, MIT researchers used water-repellent magnetic nanoparticles to separate spilled oil from ocean water.
