Researchers in China have shown that the organic component of mother of pearl can help repair damaged teeth, by acting as a template for the mineralisation of tooth enamel.

Tooth enamel is made up of rod-like crystals of hydroxyapatite, a calcium phosphate mineral. It is the hardest tissue in the body, but is susceptible to erosion by food and bacterial acids. Once gone, it never naturally reforms, and cavities must be fixed using manmade materials. Methods of artificially rebuilding enamel often involve extreme temperature, pressure or pH conditions that make them impractical for clinical use.

A group of UK chemists has used a desktop inkjet printer to prepare a metastable form of the anti-epileptic drug carbamazepine. Co-crystals have been prepared by first depositing very small droplets of template solution followed by droplets of the drug solution, which leads to rapid evaporation and crystallisation. Simon Gaisford of UCL School of Pharmacy, London, who lead the project, told Chemistry World that this polymorph has only been produced previously by layering it molecule by molecule onto a template crystal using vapour deposition.

‘Desktop inkjet printers offer amazing control of droplet position in order to produce photographic images,’ says Gaisford. ‘So in this instance the technology can really be considered to be more advanced than is needed for crystal templating, although it is evident that the smaller the droplet size and printing resolution the better the potential of the technique.’

German scientists hunting dark matter are set to produce half a tonne of high-purity calcium tungstate for their detectors, one 1kg crystal at a time. The CRESST-II experiment based in Gran Sasso, Italy is currently seeking this enigmatic substance, thought to explain the universe’s structure, with 10kg of calcium tungstate (CaWO4). Now Andreas Erb and Jean-Côme Lanfranchi are preparing crystals for its larger successor EURECA, which will begin operation in the French Alps in 5–10 years.

Gravitational effects suggest as-yet-unobserved dark matter in the universe outnumbers more familiar atomic matter four to one. Erb, Lanfranchi and their colleagues are hunting leading theoretical candidates, Weakly Interacting Massive Particles (WIMPs). That name reflects their size – up to a lead atom’s mass – and the limited interaction with atomic matter that makes them hard to find, or ‘dark’. ‘They have to interact weakly to agree with the matter needed,’ says Richard Gaitskell from Brown University in the US, who isn’t involved in the calcium tungstate experiments.

The IUPAC task group: Coordination polymers and metal organic frameworks: terminology and nomenclature guidelines have published provisional recommendations. The article can be accessed directly here and any comments can be directed to the task group chair, Professor Lars Öhrström.

The task group was set-up in 2009 to document, analyse and evaluate the use of nomenclature and terminology in the areas of coordination polymers and metal-organic frameworks. As well as meeting on three occasions the group also published a Highlight article detailing the need for terminology guidelines and the provisional recommendations, which include the following definitions:

There are also recommendations on net and network topology, topology descriptors, nomenclature and the use of other terms (which explicitly discourages the term “hybrid organic-inorganic materials”)

Researchers from China have designed coordination frameworks which exhibit varing levels of luminescence when exposed to air of different humidities.

The porous terbium-based metal organic framework reversibly absorbs/desorbs water molecules into its structure. When additonal water molecules are coordinated to the framework, the compound emits a bright green colour (easily detectable by the naked eye) – the result of a reduced O-H vibrational quenching in the complex.
