Renal failure culprit: growth of melamine–cyanuric acid crystals

29 Sep 2010

Daniele Musumeci and Michael D. Ward study the growth of melamine-cyanuric acid crystals using real time in situ atomic force microscopy. Read more about their research in this CrystEngComm Hot Communication which reveals that hydrophobic interactions between 2D hydrogen-bonded planar sheets play a dominant role in the crystal growth of this material, which has been shown to cause renal failure.

Polycrystal peacocks

29 Sep 2010

Polycrystalline patterns are complex and often difficult to distinguish by eye alone. Erica Gunn, Bart Kahr and colleagues use extinction mapping techniques to study the development of polycrystalline patterns from solution, carefully controlling the crystallization driving force. Read more about their study and check out the beautiful and mesmerising patterns in their CrystEngComm Hot Article!

In the ‘metastable’ zone: crystal nucleation investigated

29 Sep 2010

Crystallization from solutions is used for the separation and purification of industrial chemicals and for controlling the shape and size of final crystalline products. The efficiency of these processes is determined by the nucleation of crystals and their development in the liquid phase, and is intimately connected with the metastable zone width of the liquid phase. In this CrystEngComm articles Keshra Sangwal investigates the metastable zone width of various systems using the polythermal method to further the understanding of these important processes.

October Crystal Clear: Chocablock

20 Sep 2010

(111) Twinned BaTiO3 Microcrystallites

This month’s Crystal Clear is chocablock with beautiful BaTiO₃ microcrystallites. This (111) twinned structure was obtained through a composite hydroxide mediated process by using amorphous TiO₂ powders.

The striking image is taken from an article in Issue 10 by Duo Liu and coworkers (Shandong University, China):
