Water stays in the pipes longer in shrinking cities – a challenge for public health

The geographic locations where Americans live are shifting in ways that can negatively affect the quality of their drinking water.| Short Read

Cities that experience long-term, persistent population decline are called shrinking cities. Although shrinking cities exist across the U.S., they are concentrated in the American Rust Belt and Northeast. Urban shrinkage can be bad for drinking water in two ways: through aging infrastructure and reduced water demand.

The material sandwiches a thin layer of silver between two “dielectric” materials, aluminum oxide and zinc oxide, producing a conductive anti-reflection coating on the sheet of plastic.

Making plastic more transparent while also adding electrical conductivity

Michigan Engineers change the game by making a conductive coating that’s also anti-reflective. | Medium Read
