Structure of the World Crystal [PDF]
Australian Journal of Physics, 1998 Identifying space with a superconducting cosmic dust, the structure of the ‘world crystal’ is built. Particles moving on open geodesics are assimilated with the ‘electron gas’ in a lattice, and those moving on closed geodesics with nodes of the same lattice.

The Crystal Structure of NaPt3O4 [PDF]
The Journal of Chemical Physics, 1951 The structure of a microcrystalline platinum compound is derived from x-ray data. Space group Oh3—Pm3n, a0=5.69A, with 6 Pt at ±(¼ 0 ½, ↺), 8 O at ±(¼ ¼ ¼, ¼ ¾ ¾, ↺), and 2 Na at (000, ½ ½ ½), corresponding to the formula NaPt3O4. The coordinations are as follows: platinum 4 O and 2 Pt, oxygen: 3 O and 2 Na, sodium: 8 O.

Crystal Structures of Two 4-Alkyl-8-hydroxyquinolines
Molbank4-Methyl- (1) and 4-ethyl-8-hydroxyquinoline (2) crystallize from a mixture of diethyl ether and chloroform in the triclinic space group P1¯. X-ray analysis reveals that both compounds form discrete molecular dimers stabilized by intermolecular O-H∙∙∙N ...

Evolution of crystal structures in GeTe during phase transition
Scientific Reports, 2017 We investigated changes in the crystal structure of GeTe during its phase transition. Using density functional theory (DFT) calculations, four possible crystal structures were identified: R3m, P1, Cm, and Fm3m.

Polytypism of crystal structures
Computers & Mathematics with Applications, 1988 AbstractPolytypism occupies a singular position in the structural crystallography uniting features of polymorphism and diversity of crystal structure built of definite units. In the structural systematics the polytype structures are considered in relation to fragmentary, interstratified, hybrid (both commensurate and incommensurate), order-disorder (OD)

Crystal structure of fenclorim
Acta Crystallographica Section E Crystallographic Communications, 2015 In the title compound, C10H6Cl2N2(systematic name: 4,6-dichloro-2-phenylpyrimidine), which is used commercially as the herbicide safener, fenclorim, the dihedral angle between the dichloropyrimidyl and phenyl rings is 9.45 (10)°. In the crystal, C—H...N hydrogen bonds link adjacent molecules, forming chains along thec-axis direction.

Crystal twinning of bicontinuous cubic structures
IUCrJ, 2020 Bicontinuous cubic structures in soft matter consist of two intertwining labyrinths separated by a partitioning layer. Combining experiments, numerical modelling and techniques in differential geometry, we investigate twinning defects in bicontinuous ...
