    Invent by Number: Researchers predict, then produce superior titanium alloys

    Researchers have developed a new method or making titanium-based alloys with many qualities far superior to those in any alloy previously known.

  5. Materials Science

    A New Cool: Prototype chills fast and electrifies, too

    Researchers have incorporated an efficient thermoelectric material into a prototype device that can cool or produce electricity.

  6. Materials Science

    A Hard Little Lesson: Squeezed nanospheres grow superstrong

    A substance not known for its hardness—silicon—becomes one of the hardest of materials when formed into ultrasmall spheres.

  7. Materials Science

    A new carbon nanotool springs to life

    Physicists have pulled out the inside cylinders of multiwall carbon nanotubes, as if expanding a telescope, indicating how the devices may serve as tiny bearings and springs in future nanomachines.

    Technique may yield vocal cord stand-in

    A plastic material used in some biological implants could someday form a foundation for tissue that can repair or replace human vocal cords.

  11. Materials Science

    Ceramic rebounds from stressful situations

    The ceramic titanium silicon carbide can fully recover after being compressed to a degree that would leave most ceramics shattered and most metals permanently deformed.
