Multislice imaging of integrated circuits by precession X-ray ptychography
10.1107/S205327331701525X 2017-12-22 A method for nondestructively visualizing multisection nanostructures of integrated circuits by X-ray ptychography with a multislice approach is proposed. In this study, tilt-series ptychographic diffraction data sets of a two-layered circuit with a ∼1.4 µm g... |

Quasicrystals: What do we know? What do we want to know? What can we know?
10.1107/S2053273317016540 2017-12-07 More than 35 years and 11 000 publications after the discovery of quasicrystals by Dan Shechtman, quite a bit is known about their occurrence, formation, stability, structures and physical properties. It has also been discovered that quasiperiodic self-assemb... |

Small-angle X-ray scattering tensor tomography: model of the three-dimensional reciprocal-space map, reconstruction algorithm and angular sampling requirements
10.1107/S205327331701614X 2017-12-07 Small-angle X-ray scattering tensor tomography, which allows reconstruction of the local three-dimensional reciprocal-space map within a three-dimensional sample as introduced by Liebi et al. [Nature (2015), 527, 349–352], is described in more detail with reg... |

Construction of weavings in the plane
10.1107/S205327331701422X 2017-11-15 This work develops, in graph-theoretic terms, a methodology for systematically constructing weavings of overlapping nets derived from 2-colorings of the plane. From a 2-coloring, two disjoint simple, connected graphs called nets are constructed. The union of ... |

Improving the convergence rate of a hybrid input–output phasing algorithm by varying the reflection data weight
10.1107/S205327331701436X 2017-11-15 In an iterative projection algorithm proposed for ab initio phasing, the error metrics typically exhibit little improvement until a sharp decrease takes place as the iteration converges to the correct high-resolution structure. Related to that is the small co... |
