A core of concentric nanotubes could oscillate at gigahertz frequencies–faster than any other mechanical oscillator.

Scanning tunneling microscopes may be producing distorted images, according to a computer simulation.

The mechanical properties of a metal hold up even at nanometer scales.

Liquid crystals can crystallize even above the usual ‘melting’ temperature if they are placed in a narrow space between two surfaces.

Nanotubes of boron and nitrogen have now been imaged in great detail in a set-up that insulates them from contamination.

Pairs of atomic-scale images made from photoelectron diffraction with circularly polarized light can be merged into a stereoscopic, 3D view.

Carbon nanotubes’ electrical resistance is changed when ‘buckyball’ cages of carbon atoms–with a single gadolinium atom in each–are placed inside the tubes.

‘Nanotomography’ uses a scanning probe microscope–a surface imaging device–to create 3D images of solid materials at the atomic scale.

Researchers have stretched ‘ropes’ of carbon nanotubes to their breaking point–the most direct measurements to date of the stength of nanotubes.

Physicists have made the first direct measurements of the force exerted by a single atom in a solid.

The smallest conducting rings ever made (50 nm in diameter) can host single electrons in pure quantum states, giving researchers a new tool and new conditions under which to study electrons.

The first atomic-scale images of nanocrystals that help reduce pollution show some surprises that should help researchers improve the chemical process.

Researchers have shown nanotube junctions have the right properties to make useful circuit elements for nano-scale electronics.
