Sponge made of coffee grounds scrubs lead and mercury from water

Homes, restaurants, and the coffee industry collectively produce about 6 million tons of spent coffee grounds every year. Researchers have now come up with a practical way to use some of this waste. They have made a rubbery foam from used coffee powder and silicone that can pull lead and mercury ions from water (ACS […]

Now boarding: Commercial planes take flight with biobased jet fuel

This year, renewable jet fuel took off, graduating from demonstration and test flights to some regular commercial use. In January, some flights left the airport in Oslo, Norway, running on jet biofuel produced from an oilseed crop. In March, United Airlines became the first U.S. airline to use biofuel for regularly scheduled commercial flights leaving […]

Plastics shine bright to warn of invisible cracks

Microscopic chinks in a material can spread and grow into larger fissures—ones that can split apart the plastics and composites used in airplanes, spacecraft, electronics, sports equipment, and pipes. A new, simple technique uses embedded microcapsules to reveal tiny, invisible cracks in a wide variety of plastics by making the cracks glow (ACS Cent. Sci. […]
