In this CrystEngComm Hot Article, Hongzheng Chen and colleagues synthesized uniform PbS nanocrystals using a surfactant-free electrodeposition method.

They investigated the effect of the concentration of Cl⁻ ions, deposition time and applied deposition current in tuning the morphology of the crystals.

The authors believe the method could be extended to the shape-controlled synthesis of other semiconductor crystals, especially metal sulfides.

Masato Uehara and Hideaki Maeda look at unusually shaped zinc sulphide nanocrystals in this CrystEngComm Hot article.

The scientists from Japan, made ZnS nanocrystals with a conical head, rather than the expected truncated pyramid.
