Nanoscale peeling. A semiflexible thin film detaches from a surface with an array of nanometer-sized bumps. Thermal fluctuations in the attraction strength between the film and the bumps at the crack front could affect how easily the film peels away, according to a new model.
This simulation of a one-nanometer wide Indium Nitride wire shows the distribution of an electron around a positively charged ‘hole.’ Strong quantum confinement in these small nanostructures enables efficient light emission at visible wavelengths.

More than a thousand end caps that make up this Rice University logo represent a fraction of those surveyed by Rice researchers who determined that the energies employed in cap formation do not contribute to the chirality of carbon nanotubes. Chirality refers to the angle of hexagons in nanotubes and dictates their electronic and other desirable properties.
