Ultracold gases in time-dependent magnetic fields

It is now technically possible to hold groups of atoms at temperatures that are only a few hundredths of a degree above absolute zero. This so-called 'ultracold gas' loaded in an optical lattice is an extremely powerful platform ...

Cathode 'defects' improve battery performance

Engineers strive to design smartphones with longer-lasting batteries, electric vehicles that can drive for hundreds of miles on a single charge, and a reliable power grid that can store renewable energy for future use. Each ...

Finding the source of chemical reactions

Scientists are constantly searching for the source of things like the origin of the universe, matter or life. Scientists at the U.S. Department of Energy's (DOE) Argonne National Laboratory, in a collaboration with the Massachusetts ...
