  • mp-4300: Yb2Si2O7 (monoclinic, C2/m, 12) - Materials Project

    materialsproject.org/materials/mp-4300 Yb2Si2O7 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Yb3+ is bonded to six O2- atoms to form distorted YbO6 octahedra that share corners with six equivalent SiO4 tetrahedra and edges with three equivalent YbO6 octahedra. There are two shorter (2.30 Å) and four longer (2.35 Å) Yb–O bond lengths.
  • Control rod - Wikipedia

    en.wikipedia.org/wiki/Control_rods Control rods are used in nuclear reactors to control the fission rate of uranium and/or plutonium.Their compositions includes chemical elements such as boron, cadmium, silver, and/or indium, that are capable of absorbing many neutrons without themselves fissioning. These elements have different neutron capture cross sections for neutrons of various energies.
