Crumpled sheets reveal a mechanism for glassy relaxations

We often crumple a scrap piece of paper into a ball before throwing it. This mundane action, however, creates a unique complex system with surprising mechanical properties. Take a thin plastic sheet such as cellophane and ...

Scientists detect exponential relaxation spectrum in glasses

Prof. Wang Junqiang's team at the Ningbo Institute of Materials Technology and Engineering (NIMTE) of the Chinese Academy of Sciences has revealed the exponential relaxation events during the recovery process of glasses, ...

Controlling how fast graphene cools down

Graphene is the thinnest material ever produced, with the thickness of a single atomic layer. Thinner than a billionth of a meter, it is able to efficiently absorb light from the visible to the infrared through the photoexcitation ...
