(Nanowerk Spotlight) Poisson's ratio describes the fundamental elasticity of any solid. Conventional materials contract laterally when stretched and Poisson's ratio expresses the ratio of transverse ...

The defining property of an auxetic material is, then, that it possesses one or more negative Poisson’s ratios (as opposed to the positive Poisson’s ratio displayed by ‘normal’ materials). Do you have ...

Osteodentin found in the core of this bottom-dwelling Atlantic Ocean predator's teeth could inspire new designs for stronger, ...

This study is led by Prof. Hao Wu (Flexible Electronics Research Center, State Key Laboratory of Intelligent Manufacturing Equipment and Technology, School of Mechanical Science and Engineering, ...

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

A group of scientists, including specialists from Landau Institute for Theoretical Physics (ITF), described a universal characteristic, in which many unique graphene properties are "hidden". It turned ...

(Nanowerk News) Stretchable electronic devices are usually implemented on 2D surfaces of some base elastomeric materials – these devices then deform following the stretching deformation of this base ...

Why auxetic materials offer some unique advantages in sensor fabrication. How additive manufacturing was used with autextic materials to create unique pressure and force sensors. The structure and ...
