Part three of the ingredients and their uses series, minerals! Take care of your body: lick a rock today!

Very few of these are the minerals described in the article, but they look cool so here we are.Photo by Edz Norton on Unsplash Minerals are underrated. For a lot of minerals, only a tiny amount is needed for them to take an immense part in the body’s ability to stay alive and well. Many come from rocks, but often those rocky mineral sources are broken up and modified by plants, or simply mixed…

Capturing Dissolved Carbon Dioxide and Toxic Ions From Water in Tiny “Nanojars”

Carbon dioxide from the atmosphere can dissolve in oceans, lakes, and ponds, forming bicarbonate ions and other compounds that change water chemistry, with possible harmful effects on aquatic organisms. In addition, bicarbonate can reenter the atmosphere as carbon dioxide later, contributing to climate change. Now, researchers have developed tiny “nanojars,” much smaller than the width of a human hair, that split bicarbonate into carbonate and capture it, as well as certain toxic anions, so the ions can be removed and potentially recycled.

The researchers will present their results today at the fall meeting of the American Chemical Society (ACS). ACS Fall 2021 is a hybrid meeting being held virtually and in-person August 22-26, and on-demand content will be available August 30-September 30. The meeting features more than 7,000 presentations on a wide range of science topics.

“We originally developed nanojars to extract harmful negatively charged ions, like chromate and arsenate, from water,” says Gellert Mezei, Ph.D., who is presenting the work at the meeting. “But it turns out that they also bind strongly to carbonate.” Carbonate or other ions captured in the nanojars could later be disposed of or recycled into useful products, he says.

Fossilized bivalve shells buried in an ancient sea sediments are receiving daylight for the first time in ~250 million years. These sediments are rich in iron minerals, which has replaced the carbonate shell material and preserved the original texture of the shell. Thank you iron oxides for preserving the growth layering of this shell for us to admire.
