    Data for the ‘Orchid Observers’ project by Shuttleworth, S, O’Donnell, J, Lintott, C, Tweddle, J

    Published 2017
    “…Volunteers can also extract valuable information from the 15,000 historical herbarium sheets in the NHM. Once the complete dataset has been fully verified and analysed for publication, the historical (i.e. herbarium) data and 2015 field observations will be made freely available through the National Biodiversity Network (https://data.nbn.org.uk/) and NHM Data Portal (http://data.nhm.ac.uk /). …”

    Topochemical fluorination of some Ruddlesden-Popper phases by Zhang, R

    Published 2017
    “…The introduction of a cooperative octahedral tilt around the crystallographic z-axis leads to a local breaking of the inversion symmetry of the host lattice on fluorination, although the global inversion symmetry of the lattice is retained due to an alternation in the z-tilt direction in adjacent perovskite sheets.</p> <p>The substitution of Sr<sup>2+</sup> with Ca<sup>2+</sup> cations in YSr<sub>2</sub>Mn<sub>2</sub>O<sub>7</sub> led to an increasing distortion of the metal-oxide framework, resulting in the formation of an orthorhombic symmetry in space group <em>Pnnm</em> adopted by YSr<sub>0.5</sub>Ca<sub>1.5</sub>Mn<sub>2</sub>O<sub>7</sub>. …”
