Water ice is ordinarily fragile and breaks if extended by simply <0.1 % (1). On web swear 187 of this divulge Xu et al. (2) existing that fibers of frigid ice about a micrometers or less in diameter can bend without breaking proper into a come-circular form tens of micrometers in radius. Upon unloading, the fibers spring relieve to their popular form. Such strains are come the theoretical limit of ∼15% (3), so the deformation is fully elastic. The microfibers can transmit viewed light as successfully as converse of the art work on-chip light guides (4, 5). The authors moreover catch that obscene bending creates a come-ground layer on the compressive facet that transforms somewhat speedy from ice Ih (hexagonal crystal structure) to ice II (rhombohedral crystal structure). This pronounced elasticity and transparency heart of attention on the absence of defects sooner or later of the fabric, and the structure replace implies a low barrier for the ice Ih-to-II transformation.
