Bistable Isochoric Chiral Metamaterials with Reprogrammable Multiaxial Responses

Advanced Functional Materials, EarlyView.
An isochoric bistable rotational unit cell enables in situ modification of internal contact conditions post‐fabrication, without altering the global envelope dimensions of the surrounding architecture. By selectively switching between open and closed states, the tessellated chiral metamaterial can reprogram its volumetric response, including bulk ...

The thorium isomer [PDF]

Today’s most precise timekeeping is based on optical atomic clocks. However, those could potentially be outperformed by a nuclear clock, based on a nuclear transition instead of an atomic shell transition.

Thorium in environment

, 2010
All known isotopes of thorium are radioactive, 6 of them occur in nature decay chains. Thorium forms mainly cation Th4+ . Because thorium behaves like REE, Ce, Zr, Hf, Sc and U, it is a problem with thorium separation.
