Strangelets, and specifically nuclearites, their heavy species, are very dense, compact and potentially fast objects made of large and roughly equal numbers of up, down and strange quarks, which may inhabit the universe. ...
(Phys.org)—Over the past few years, Li-air batteries (more precisely, Li-oxygen batteries) have become attractive due to their theoretical ability to store nearly as much energy per volume as gasoline. The key to this high ...
Gas giants orbiting our sun show a clear pattern; the more massive the planet, the lower the percentage of "heavy" elements (anything other than hydrogen and helium) in the planet's atmosphere. But out in the galaxy, the ...
