Scientists spy on growing nanoparticles
French scientists have developed a new method that monitors the growth of nanoparticles in real time
Electrons trapped by laser beam
The experiment was carried out inside a vacuum chamber filled with a low density nitrogen or argon gas. A wave plate – in the form of a small circular piece of material – was inserted into...
Superfluid helium as a vacuum
In an ingenious series of experiments the Göttingen team squirted liquid helium through a fine nozzle to create drops containing about 104 atoms at a temperature of 0.1 K. The team used laser spectro...
