“Dry water.” Credit: ACS. The American Chemical Society today distributed a story that came out of one of its meetings regarding the use of “dry water” powder as a medium for absorbing CO2, enhancing certain chemical reactions and storing emulsions. Although the story is interesting, it’s not exactly clear to me if the CO2 angle, …

Lithium batteries that utilize oxygen as the cathode material are very promising owing to their extremely high theoretical capacity of almost 12,000 Wh kg-1. In these lithium-air batteries, oxygen is adsorbed directly from the atmosphere when required rather than being stored in the battery itself. In practice, a combination of carbon powder, oxygen, oxygen reduction …
