Experimental physicists have successfully cooled molecules in a gas of sodium potassium to a temperature of 500 nanokelvins -- just a hair above absolute zero, and over a million times colder than ...

When you get right down to the atomic scale, things happen much faster than we’re used to. That makes it hard to actually see what happens during chemical reactions, so researchers at Harvard have ...

Potassium nitrate (KNO 3), known historically as saltpeter or the mineral niter, is a common salt with multiple uses. It has been known since antiquity; an early appearance in the chemical literature ...

Physicists in the US have moved a step closer to controlling the electronic properties of individual molecules in a condensed matter environment. Michael Crommie and colleagues at the University of ...
