This graph shows the correlations between three parameters that lead to a single descriptor which provides a rational basis to design electrolyte compositions for high-power alkali metal-oxygen batteries, including potassium-air batteries. This research from the McKelvey School of Engineering will help engineers find the right electrolyte for new and improved batteries, including potassium-air batteries. (Credit: Ramani Lab)

Single easy to measure parameter to choose electrolyte for alkali-Metal air batteries

Metal air batteries have been considered as a successor to lithium-ion batteries which could potentially make electric cars to cover thousand miles or more in single charge had the only challenge of choosing the right electrolyte.

Environmental scientists testing carbon dioxide abatement are using underground basalt flows to contain and convert the gas to an inert mineral. A new series of experiments conducted at Washington University give a new, precise look at the process. (Photo: Joe Angeles/Washington University)

Study sheds light on what happens underground when CO2 is injected into basalt

At the point when petroleum products are singed, carbon dioxide (CO2) is radiated. As the gas rises and ends up caught in the climate,...
