Understanding the Mechanisms of Carbon Dioxide Mineralization in Ultrathin Films of Water

A new high-profile scientific review article in Nature Reviews Chemistry discusses how carbon dioxide (CO2) converts from a gas to a solid in ultrathin films of water on underground rock surfaces. These solid minerals, known as carbonates, are both stable and common.

Compound commonly found in candles lights the way to grid-scale energy storage

Scientists at the U.S. Department of Energy s Pacific Northwest National Laboratory have shown that low-cost organic compounds hold promise for storing grid energy. Common fluorenone, a bright yellow powder, was at first a reluctant participant, but with enough chemical persuasion has proven to be a potent partner for energy storage in flow battery systems, large systems that store energy for the grid.
