Materials Science

  1. Physics

    Scientists seek materials that defy friction at the atomic level

    Scientists investigate superslippery materials and other unusual friction feats.

  2. Materials Science

    Permanent liquid magnets have now been created in the lab

    Magnets that generate persistent magnetic fields are usually solid. But new little bar magnets have the mechanical properties of liquids.

  3. Materials Science

    Latest claim of turning hydrogen into a metal may be the most solid yet

    If true, the study would complete a decades-long quest to find the elusive material. But such claims have been made prematurely many times before.

    50 years ago, bulletproof armor was getting light enough to wear

    In 1969, bulletproof armor used boron carbide fibers. Fifty years later, bulletproof armor is drastically lighter and made from myriad materials.

  5. Chemistry

    How seafood shells could help solve the plastic waste problem

    Chitin and chitosan from crustacean shells could put a dent in the world’s plastic waste problem.

  6. Materials Science

    A new graphene foam stays squishy at the coldest temperatures

    Researchers have now made a material that is superelastic even at extremely cold temperatures, which could be helpful in space.

  7. Materials Science

    Bacteria can be coaxed into making the toughest kind of spider silk

    Lab-altered bacteria have made a copy of a spider’s strongest silk strands, which could one day be used to make more sturdy materials.

  8. Physics

    How droplets of oil or water can glow vibrant colors

    Viewed from various angles, tiny droplets of water or oil glow different colors under white light.

  9. Materials Science

    A new insulation material is practically weightless yet still durable

    Extreme heat and temperature swings are no match for this lightweight insulator.

  10. Materials Science

    A new fabric becomes more breathable as you work up a sweat

    A yarn-based textile can switch from breathable to insulating and back again, depending on how much you sweat.

  11. Materials Science

    Being messy on the inside keeps metamaterials from folding under stress

    Inspiration from disordered arrangements of atoms in crystalline metals may lead to longer-lasting, next-gen materials.

  12. Materials Science

    Magnets make a new soft metamaterial stiffen up in a flash

    Scientists can dial the stiffness of a bizarre new type of synthetic material up or down using magnets.
