'Weighing' atoms with electrons

Researchers used an advanced scanning transmission electron microscope to measure isotopes in nanometer-sized areas of a graphene sample. The same energetic electrons that form an image of the graphene structure can also eject one atom at a time due to scattering at a carbon nucleus.

Lights, action, electrons!

Electrons are far too small and fast to be seen, even with the help of a light microscope. This has made measuring an electron's movement very difficult for the past century. However, new research has made this process much easier.

Physicists observe diffusion of individual atoms in light bath

In a combination of experiments and theory the diffusion of individual atoms in periodic systems was understood for the first time. The interaction of individual atoms with light at ultralow temperatures close to the absolute zero temperature point provides new insights into ergodicity, the basic assumption of thermodynamics.

Metamaterial uses light to control its motion

Researchers have designed a device that uses light to manipulate its mechanical properties. The device, which was fabricated using a plasmomechanical metamaterial, operates through a unique mechanism that couples its optical and mechanical resonances, enabling it to oscillate indefinitely using energy absorbed from light.
