Sea urchin-inspired cement could enable more fracture-resistant concrete

December 12th, 2017 | by April Gocha

Researchers at the University of Konstanz in Germany have shown that they can engineer stronger cement by giving the material a nano-level brick and mortar structure. Adding polymer binders into cement to control its nanostructure, the researchers developed a material 40–100 times more fracture resistant than standard concrete.

Brittle starfish offers lessons in creating durable ceramics

December 12th, 2017 | by Faye Oney

Scientists have discovered that a brittle starfish has the capability to create a durable "tempered" ceramic material while underwater. Its process is similar to the creation of tempered glass, but without the heating and cooling process.

Video: Silica layer enables tuning of structural colors for biocompatible pigments that don’t fade in tattoos, paints, foods, and more

September 20th, 2017 | by April Gocha

Researchers report a simple method to manufacture biocompatible structural colors using only melanin and silica. The silica shell provides a buffer layer of tunable thickness that allows customization of the particular color, offering the potential to fabricate a new breed of long-lasting pigments that don’t fade.
