Activity: Ingenious: The World Has a Receipt Problem Video Questions Mark as Favorite (6 Favorites)
In this activity, students will answer questions while watching the video The World has a Receipt Problem 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 process of thermal printing on receipts, and the limitations related to the paper that currently prints using leuco dyes. This heat-sensitive ink appears when it reacts with an acid developer embedded in the paper. Scientists are working to develop a new kind of thermal receipt paper, that can use the same printers, however it offers many additional benefits and potential uses.

Video: Ingenious Video 7: The World has a Receipt Problem Mark as Favorite (7 Favorites)
The receipts you take home from the store – or stuff in your bag, or lose in your car -- employ a printing method that’s been around since the 1970s. Thermal printing involves heat-sensitive inks called leuco dyes that show up when they react with an acid developer embedded in the paper. Not only do these inks fade easily, but receipts that use them aren’t recyclable, and could even be dangerous to your health. Taking a cue from a failed experiment, scientists are developing a new kind of receipt paper that will use the same thermal printers without leuco dyes. Instead of acid developers, this paper is coated in reflective microspheres that collapse under heat, allowing regular ink underneath to show through.

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.

Video: Ingenious Video 4: How Science Is Fixing Recycling's Grossest Problem Mark as Favorite (2 Favorites)
Polypropylene recycling has a problem: It stinks. Food and other residues are almost impossible to remove entirely from polypropylene, a.k.a the number “5” plastic of grocery-store fame. Those residues – anything from yogurt to garlic, from fish oil to baby food – not only stick to polypropylene, they degrade there and start to smell even worse! Current polypropylene recycling techniques are more down-cycling than re-cycling. Unless you break down its molecules through a highly energy-intensive refining process, the material can only get a second life as a black trash can or an underground pipe – wherever its smell doesn’t matter. But a new technique, called dissolution recycling, is changing all that. Dissolution recycling uses a special hydrocarbon polymer solvent under finely controlled conditions of temperature and pressure to eliminate ALL of the contaminants embedded in the plastic.
