Setting out from König & Smith (2021), we present an analytic morphing of zincblende- and diamond-structure nanowire (NWire) cross sections to arbitrary convex shapes as encountered in experiment. We predict the NWire atoms, bonds between these atoms and NWire interface bonds, plus characteristic lengths and area of the NWire cross sections. Cross section areas, ratios of internal bonds per NWire atom enable an interpretation of any spectroscopic NWire data. Our algorithms include a radial dependence of the NWire unit-cell parameter and can be applied to multi-core-shell NWires where NWire layers can be morphed independently from each other.

A state-of-the-art multilayer deposition system has been developed at Diamond Light Source; this instrument is engineered to produce single and multilayer coatings, accommodating mirrors up to 2000 mm in length through the utilization of eight rectangular cathodes.

A zinc(II) compound, prepared by reaction of Zn(NO₃)₂·6H₂O with furan-2,5-di­carb­oxy­lic acid and bis­[4-(2-methyl-1H-imidazol-1-yl)phen­yl] ether, possesses a fourfold inter­penetrating diamond-like three-dimensional framework. The compound exhibits a strong fluorescence emission in the solid state at room temperature.

The novel quaternary thio­germanate Li₄CdGe₂S₇ was discovered from a solid-state reaction at 750 °C. The com­pound adopts the Cu₅Si₂S₇ structure type, which is a derivative of lonsdaleite. Li₄CdGe₂S₇ appears to be a better IR nonlinear optical candidate than Li₂CdGeS₄ and one of the most promising contenders to date.

A robust theoretical analysis of thermal management of cryo-cooled Si monochromators in hard X-ray beamlines is developed. This universal theory has been validated by extensive finite-element analysis studies, offering guidances to assess the heatload deformation quickly.

A cadmium(II) com­pound, prepared by reaction of Cd(NO₃)₂·4H₂O with naphthalene-1,4-di­carb­oxy­lic acid and bis­[4-(2-methyl­imidazol-1-yl)phenyl] ether in a mixture of H₂O and di­methyl­formamide, possesses a fourfold inter­penetrating diamond-like three-dimensional framework. The com­pound exhibits strong fluorescence emission in the solid state and excellent photocatalytic activity for the degradation of methylene blue (MB) at room temperature.

The experimental setup of the Xpress beamline at the Elettra synchrotron (Trieste, Italy) is described, along with the procedures for single-crystal centring and X-ray diffraction data collection and processing. The reported results demonstrate the possibility to perform in situ high-pressure single-crystal X-ray diffraction experiments at the Xpress beamline.

The crystal structures of the title compounds have been studied to confirm that the solid-state photochemical nitro–nitrito linkage isomerization is restricted by the reaction cavity of the nitrite ion in the thio­cyanate salt.

Interpenetrant cubes of natural diamond have been formed by fibrous growth upon a twin origin.
