The crystal structures of centrosymmetric, zone-boundary-tilted perovskite-structured phases with space group Pbnm can be decomposed in terms of an appropriate set of symmetry-adapted basis vectors, for irreducible representations with wave vectors on the surface of the Brillouin zone of the cubic aris...

We couple random forest (RF) and multiple layer perceptron (MLP) neural network models with three types of features: Magpie, atom vector, and one-hot encoding (atom frequency) for the crystal system and space group prediction of materials. Four types of models for predicting crystal systems ...

help classify crystal structures. However, while there are only 230 crystallographic space groups, two crystal structures belonging to the same space group can nevertheless be very different from the point of view of local connectivity, unit cell size and number of distinct sites within the unit ...
The P6(1) crystal form, which represents a new space group for A-DNA decamers, supports one of the most hydrated and extended DNA duplexes to date, while the second orthorhombic form supports one of the least-hydrated and most-condensed non-Z-DNA duplexes. The unmethylated analogue d(CC...
In parallel to the experimental side, also theab initioquantum chemical analysis of these materials made enormous progresses in the past decade, which enable calculation of a number of properties that are not straightforwardly available from measured scattering intensities. ...
The production of pultruded composites may result in a number of manu-facturing defects such as porosity, fiber waviness, matrix cracks, or areas of resin richness or starvation. Microcracks exposed to repeat environmental and mechanical loading may result in the cracks coalescing to form areas where...
