TL;DR: It is concluded that only a small part of the provided Al is incorporated into the ZnO structure by substitution of Zn, and calculated (27)Al quadrupole coupling constants serve as a spectroscopic fingerprint by which previously suggested point-defects can be identified and in their great majority be ruled out.

TL;DR: A recipe for an improved semi-automated cluster setup is proposed which allows the treatment of crystals composed of highly charged ions and covalent networks.

TL;DR: In this article, the preparation and structural characterization of nanoscale fluorine doped tin-oxide (SnO2:F, FTO) nanoparticles with different doping levels are prepared, which show narrow size distribution as measured by X-ray diffraction, electron microscopy and dynamic light scattering They were converted into electrically conductive optically transparent films at 500 °C by a specific thermal treatment.

TL;DR: Despite the presence of side phases, the crystal structure was elucidated ab initio from high-resolution synchrotron powder diffraction data applying the charge flipping algorithm supported by independent symmetry information derived from electron diffraction (ED) and scanning transmission electron microscopy (STEM).

TL;DR: It is shown that C-symmetry based pulse sequences used for double-quantum filtering experiments can strongly be influenced by pulse transients, and a phase-tuned C-element is introduced, which can be applied to γ-encoded experiments from the C-Symmetry class, to reconstitute an almost ideal performance of the sequence.
