Researchers have created a new class of hydrogels that might prove useful in tissue engineering, drug delivery, and other biomedical applications.

Materials Science

Self-Sutures: New material knots up on its own

Researchers have used a new biodegradable material to make surgical sutures that knot and tighten themselves as they warm to body temperature.

Materials Science

Membrane Mastery: Nanosize silica speeds up sieve

A novel modification to polymer membranes gives researchers a means to tune certain filters so they separate molecules more quickly and more selectively.

Materials Science

Steely Glaze: Layered electrolytes control corrosion

Experiments with ultrathin organic coatings applied to steel suggest a new technique for slowing corrosion.

Materials Science

A Field of Diminutive Daisies

Researchers have created tiny daisies as a demonstration of a new technique that creates three-dimensional structures from carbon nanotubes.
