  Video: Ingenious Video 5: Making Shipping Greener with Hairy Ships Mark as Favorite (6 Favorites)

  The “fouling” of boats — when aquatic animals like barnacles and tubeworms attach to hulls — has been a nuisance for as long as we’ve been sailing the seas. Fouling messes up a vessel’s streamlined shape, decreasing its speed, maneuverability, and in modern times, its fuel-efficiency. Fouling spikes the carbon footprint of the shipping industry, already greater than that of most countries. For centuries, people used copper coatings to prevent fouling. Modern solutions use toxic chemical paints that pollute the water, kill marine life, and contribute to the degradation of our oceans when they wear off. A new approach is trying to work with nature instead of against it. Taking inspiration from the Salvinia plant, which is covered in tiny hair-like structures that make it basically waterproof, scientists are developing a stick-on silicone coating for ships that prevents animal hitchhikers from getting a foothold.

  Video: Ingenious Video 6: Kill More Germs by Cleaning … Less? Mark as Favorite (1 Favorite)

  There’s clean, and then there’s CLEAN. Even if something looks clean, it might still be harboring microbes – many of them harmless, some of them definitely not. With most of the ways that we clean and disinfect — that is, kill germs — the clean doesn’t last as long as you might think. Disinfectants work by attacking bacterial membranes and viral protein coats, breaking them down so that those germs fall apart and die. But the germaphobes were always right: As soon as a disinfectant dries, and a surface is re-exposed, like if someone touches or (worse) sneezes on it, it needs be disinfected all over again. The next generation of cleaning products, however, add a trick: they lay down an incredibly thin polymer layer that keeps the germ-killing ingredients in place and effective for 24 hours at a time.

  Activity: Ingenious: Making Shipping Greener with Hairy Ships Video Questions Mark as Favorite (4 Favorites)

  In this activity, students will answer questions while watching the video, Making Shipping Greener with Hairy Ships, from the Ingenious series produced by the American Chemical Society. Each episode investigates a different topic related to how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future. This episode investigates the “fouling” of boats (when aquatic animals like barnacles and tubeworms attach to hulls), and the impact it has on fuel efficiency. Since fouling is a significant contributor to the carbon footprint, this video highlights how scientists were inspired by unique aquatic plants to develop a stick-on silicone coating for ships that prevents animal hitchhikers from getting a foothold.

Each episode investigates a different topic related to how leading-edge chemistry is taking on the world’s most urgent issues to advance everyone’s quality of life and secure our shared future. This episode investigates the chemistry of cleaning. Unfortunately, clean doesn’t last as long as you might think—this video examines how disinfectants work and also how long they lasts. Scientists share about the next generation of cleaning products, that keeps the germ-killing ingredients in place and effective much longer.
