A clock built from thorium-229 has crossed an important line, from a long-discussed concept to a working device. The shift ...
Irradiation by electrons, neutrons or ions with high energies generate point defects on polycrystalline materials and these defects are absorbed and annihilated by grain boundaries (GBs) 1,2,3,4.
A light pulse redirects electrons in an ultrathin layered material, creating a stable new state without heat or damage and suggesting a low-energy route to faster electronics. (Nanowerk Spotlight) ...
