In this CrystEngComm Hot Article, Chinese scientists have prepared complex indium- and gallium-doped zinc oxide nanostructures with twin boundaries.
Three-edged nanobelts and hexagonal-disk strings were fabricated using a thermal evaporation method. Despite their differences in morphology they have the same twin boundaries, which the authors explain by introducing a twin core.
Understanding the growth of these nanostructures opens up the potential for assembling nanoscale building blocks into sophisticated structures.

elated arrays have been achieved on ITO by a ZnO nanorod templating-reaction method under different etching conditions.
A novel POM-based 3D self-penetrating MOF containing Mo–N covalent bond has been isolated under hydrothermal conditions, showing an unprecedented (4,6,6)-connected topology assembled from a 2D self-threading skeleton.
A double [2 + 2] photochemical reaction of 1,5-bis(4-pyridyl)-1,4-pentadiene-3-one (1P) was observed with in four co-crystal forms of 1P with the hydrogen bonding template molecule phloroglucinol (PG) or 5-methoxy resorcinol (MR). 1H NMR and the UV-vis spectroscopic studies established a stepwise mechanism for this reaction through the formation of a monocyclobutane intermediate.
