Air-stability of sodium-based layered-oxide cathode materials

Sodium ion batteries are considered to be one of the most promising alternative systems to lithium-ion batteries, especially for large scale applications. Sodium-based transition-metal oxides with layered structure have been ...

Earth's atmosphere may be source of some lunar water

Hydrogen and oxygen ions escaping from Earth's upper atmosphere and combining on the moon could be one of the sources of the known lunar water and ice, according to new research by University of Alaska Fairbanks Geophysical ...

Measuring carbon ion loss from the Martian atmosphere

In recent decades, planetary scientists have developed ample evidence indicating that Mars was home to a relatively thick atmosphere and hosted liquid water on its surface during the Noachian, around 4 billion years ago. ...

Zapping untreated water gets rid of more waterborne viruses

Using sophisticated microscopy and computational analysis, Texas A&M University researchers have now validated the merit of a water purification technology that uses electricity to remove and inactivate an assortment of waterborne ...
