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 ...

An international research team led by chemist Prof. Thomas Heine of TU Dresden has discovered a new two-dimensional material with unprecedented properties: regardless of whether it is strained or ...

Against common sense, auxetic materials expand or contract perpendicularly when stretched or compressed, respectively, by uniaxial strain, being characterized by a negative Poisson’s ratio ν. The ...

Auxetic materials exhibiting a negative Poisson’s ratio are of great research interest due to their unusual mechanical responses and a wide range of potential deployment. Efforts have been devoted to ...

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 -- ...

Auxetic materials are being of more and more interest to materials scientists and designers because of their ability to shrink when compressed and expand orthogonally to strain. These materials have a ...

(Nanowerk News) Researchers have confirmed the existence of a naturally occurring exotic property in which a material becomes thicker when stretched - the opposite of most materials - a discovery that ...

Researchers have discovered a new two-dimensional material with unprecedented properties: regardless if it is strained or compressed, it always expands. This so-called half-auxetic behavior is ...

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.

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 ...
