‘Nanojars’ capture dissolved carbon dioxide, toxic ions from water

Carbon dioxide from the atmosphere dissolves in waterways, 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. Now, researchers have developed tiny 'nanojars' that split bicarbonate into carbonate and capture it, as well as certain toxic anions, so they can be removed from water.
