(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 ...

Researchers have discovered a mechanism with a counterintuitive response: it becomes smaller when pulled. This rare behavior, ...

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, ...

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 could lead to ...

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 ...

Engineers use techniques from Origami to design spacecraft components, medical robots and antenna arrays. Researchers have developed a system to explain the rules that govern some of these key ...

A car that dashes against an obstacle suffers damages, first to its fenders. There is a keen interest to develop materials that can be sandwiched in the fender system which will absorb the shock and ...
