Johannesburg: In a breakthrough, engineers have created super-glass, which they claim is 200 times stronger than a standard pane.

The research was carried out by a team at McGill University in Montreal and was published in journal Nature Communications.

The glass, which is strengthened by introducing a network of microscopic cracks, is inspired by mollusc shells. It can absorb impacts better by yielding and bending slightly instead of shattering.

In the study, the team examined natural materials like mollusc shells, bone and nails and used a 3D laser to engrave microscopic fissures into glass slides.

Researchers filled the fissures with a polymer in order to make the glass 200 times tougher.

The engraved glass can stretch by almost five percent before snapping, compared to a strain capacity of only 0.1 percent for standard glass.

The newly discovered stronger glass might be useful in making bullet-proof windows, glasses, or even smartphone screens.
