Auxetics defy common sense, widening when stretched and narrowing when compressed. NIST researchers have now made the process of using them much easier. Such common-sense-defying materials do exist.

Much like sphere packing, crystalline materials can be similarly described via periodic packing of cylinders in 3D space. In this instance, the cylinders represented rods of strongly bonded atoms or ...

There are young children celebrating the holidays this year with their families, thanks to the 3D-printed medical devices created in the lab of Georgia Tech researcher Scott Hollister. For more than ...

Sandwich structures combining stiff face sheets and lightweight cores have long been valued for their high strength-to-weight ratio and energy absorption capabilities. The incorporation of auxetic ...

Regardless of whether it is strained or compressed, the new material always expands. Copyright: Thomas Heine et al. Researchers have discovered a two-dimensional ...

Most materials bulge out when you squeeze them, pushing the energy outside. But that's not always what you want — wouldn't it sometimes be better for them to collapse and hold the energy inside? These ...

The nuclei of naive mouse embryonic stem cells that are transitioning towards differentiation expand when the cells are stretched and contract when they are compressed. What drives this auxetic ...

What do a flea and an eagle have in common? They can store energy in their feet without having to continuously contract their muscles to then jump high or hold on to prey. Now scientists have created ...

Auxetics defy common sense, widening when stretched and narrowing when compressed. Researchers have now made the process of using them much easier, paving the way for new types of auxetic products -- ...

Such common-sense-defying materials do exist. They’re called auxetics, and they have a raft of unique properties that make them well-suited for sneaker insoles, bomb-resilient buildings, car bumpers ...
