    Controlling metal oxidation is an age-old problem and the integrity of the metal–oxide interface is key to long-term material stability. A deeper investigation of this buried interface reveals the processes occurring at the atomic scale, and provides tantalizing clues for alloy design.

    The extraordinarily high strength and stiffness of single-walled carbon nanotubes promises a myriad of unique applications, but many of these are reliant on the growth of ultralong, continuous nanotubes. A new synthetic procedure takes us a step closer to this goal.

    Describing the structure of amorphous materials such as metallic glasses has been a longstanding problem in materials science. A new technique called fluctuation microscopy allows us to see order on length scales that are difficult to study with traditional scattering techniques.

    Stethoscopes, loudspeakers, microphones, pressure gauges and many other common devices share a basic mechanism of operation — a pliable membrane deflecting under the influence of an external force. A nanocomposite membrane has now been developed that shows great sensitivity and autorecovery capabilities.
