3D printing approach for shape-changing materials means better biomedical, energy, robotics devices
Anisotropy refers to the property of being ... returning to their original shape when the stress is removed, like rubber. Viscoelastic materials slowly deform and gradually recover.

Study unveils a spontaneous toroidal polar topology in the helielectric nematic state
"As a particular case, we found some ferroelectric nematic materials with relatively low shape anisotropy but high polarity can directly go from the isotropic liquid to the ferroelectric nematic ...
