Researchers unveil the first chemically sensitive transmission electron microscope with single-atom resolution.

Nanoscale crystals pass through narrow constrictions in carbon nanotubes by shuttling atoms from their back end to their front end, according to new experiments.

Metal nanorods grown by physical vapor deposition can be fabricated with a much narrower diameter than previously thought, potentially enabling the design of more efficient catalysts.

A new self-assembly process creates nanowires of germanium without the metal catalyst required in earlier experiments.

Single-molecule microscopy reveals the nature of the chemical bonds between a large organic molecule and a metallic surface.

A new model for DNA-covered nanoparticles predicts their stable crystal structures and may one day help in finding the optimal building blocks for self-assembling materials.

Single atoms deposited on an iron oxide surface provide a valuable model system for studying catalysis.

Simulations provide a guide to identifying atoms in high-resolution images of carbon nanomaterials.

Understanding the role of interface effects will be essential for designing thin-film ferroelectrics on semiconductors.

Spectroscopic mapping of the luminescence of aromatic single molecules reveals the spatial distribution of radiative transitions at submolecular resolution.

Controlling defects on graphene that trap migrating metal atoms may lead to superior device fabrication.

Contrary to what is normally assumed, the polarization of sufficiently thin ferroelectrics can switch continuously, rather than through the formation of domains.

Diffraction techniques are making progress in tackling the difficult problem of solving the structures of nanoparticles and nanoscale materials.

LaAlO3/SrTiO3 interfaces grown by different methods all show a metal-insulator transition, but the observed interfacial electric field strength is not consistent with a widely studied model.

Carbon particles combining diamond and buckyball structures could form tomorrow’s optoelectronics.

A new study gives the most detailed pictures yet of an industrially useful nanoscale sponge.

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

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

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

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