New medical, research tool possible by probing cell mechanics

(PhysOrg.com) -- Researchers are making progress in developing a system that measures the mechanical properties of living cells, a technology that could be used to diagnose human disease and better understand biological processes.

The first controllable atom SQUID

(Phys.org)—Scientists have created the first controllable atomic circuit that functions analogously to a superconducting quantum interference device (SQUID) and allows operators to select a particular quantum state of the ...

Symmetry matters in graphene growth

What lies beneath growing islands of graphene is important to its properties, according to a new study led by Rice University.

ORNL microscopy explores nanowires' weakest link

Individual atoms can make or break electronic properties in one of the world's smallest known conductors—quantum nanowires. Microscopic analysis at the Department of Energy's Oak Ridge National Laboratory is delivering ...

Researchers put a new spin on atomic musical chairs

Researchers from the National Institute of Standards and Technology and the Naval Research Laboratory have developed a new way to introduce magnetic impurities in a semiconductor crystal by prodding it with a scanning tunneling ...

Shells, silicon & neighbourly atoms

What do shells, solar panels and DVDs have in common? At the atomic scale they are 'amorphous', that is -- unlike crystals -- they are built from irregular arrangements of atoms.
