Flowery magnetic microspheres clean water

Chinese scientists reveal an easy and effective synthetic method to obtain iron oxide microspheres to treat contaminated water.

Industrial wastewater containing toxic metal ions and organic pollutants has become a serious threat to the environment and public health. So the synthesis of three-dimensional micro and nanomaterials with the capability of absorbing undesired water contaminants in a straightforward and effective manner is a priority for environmental scientists.

Now Hongjie Zhang and colleagues at Changhun Institute of Applied Chemistry, have designed an easy method to synthesise flower-shaped Fe3O4 microspheres with magnetic properties, which can be used as absorbents to treat wastewater. Unlike previous synthetic routes, Zhang’s hydrothermal method avoids the use of surfactants and copolymers that would need to be removed from solution.

Renal failure culprit: growth of melamine–cyanuric acid crystals

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

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

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.

Smart seeding to create gold-silver alloy shell nanoparticles

In this CrystEngComm Hot Article, Xinling Tang and Masaharu Tsuji from Kyushu University, Japan study the effects of shapes of Au cores on the growth of Ag shells using dendritic branched Au nanoparticles as Au seeds in DMF. They succeeded in the preparation of Au core Au/Ag alloy denoted as Au@Au/Ag particles.
