Quasicrystals are perfectly ordered crystals lacking translational symmetry. Here the authors unravel the formation mechanism of two-dimensional dodecagonal quasicrystals that arise from systematic modifications of a hexagonal honeycomb structure.

Development of a robust, thin, hole-blocking (n+) contact on high purity germanium (HPGe) has been the main challenge in the development of Ge-based radiation sensors. Yttrium has been reported to be a viable hole-blocking contact on HPGe, and detect

This paper reports on the structural basis of CO2 adsorption in a representative model of flexible metal-organic framework (MOF) material, Ni(1,2-bis(4-pyridyl)ethylene)[Ni(CN)4] (NiBpene or PICNIC-60). NiBpene exhibits a CO2 sorption isotherm with c

The structural and microstructural responses of a model metal–organic framework material, Ni(3-methyl-4,4′-bipyridine)[Ni(CN)4] (Ni-BpyMe or PICNIC-21), to CO2 adsorption and desorption are reported for in situ small-angle X-ray scattering and X-

In previous work, molecular dynamics simulations based on a first-principles-derived effective Hamiltonian for Pb1-X(Sc1/2Nb1/2)O3-X (PSN), with nearest-neighbor Pb-O divacancy pairs, was used to calculate X[Pb-O] vs. T, phase diagrams for PSN with:
