High pressure converts IO3 units to hypercoordinated IO6 in K2Zn(IO3)4.2H2O forming 2D iodate networks, promotes multicenter O-H-O bonds, yields bulk modulus 22(3) GPa, and closes the band gap from 4.2 eV to 3.4 eV at 20 GPa.
YbN thin films are insulating with a 1.7 eV band gap, showing LO and TO phonon modes plus a defect-induced absorption tail indicating the Fermi level lies in a disordered conduction band minimum.
DFT calculations show guest atom ionization potential controls stability and rattler motion in A8T27Pn19 clathrates, spin-orbit coupling matters for heavy elements, and synthesis yields new compounds but misses the target phases.
Hole doping in C136 schwarzite monotonically suppresses competing magnetism while preserving high DOS (~44.7 states/eV/cell), identifying a computational route for further superconductivity screening.
Ab initio calculations on C136 schwarzite find spin-polarized distortion lowers energy by 0.213 eV/cell with retained high N(EF) ~42.85 states/eV/cell and magnetization 10.63 muB/cell.
