In a joint project with Vapourtec UK, the Wilson group in the metastable materials team have developed new flow routes to anti-solvent crystallisation of the spin-crossover active compound, iron 2,6-bipyrazol-1ylpyridine ([Fe(1-BPP)2][BF4]). In batch crystallisation, the forced precipitation of [Fe(1-BPP)2][BF4] in acetonitrile by diethyl ether results in flat, block-like crystals of widely varying sizes. By using the progressive mixing reactor developed by the team at Vapourtec UK, precipitation of microcrystals of [Fe(1-BPP)2][BF4] with a small aspect ratio has been achieved. The flow crystallisation of this high-value product has enabled, not only control over the particle size and shape, but also facilitates manufacturing scale-up for commercial applications.

Dr Lauren Hatcher won the CCDC Chemical Crystallography Prize for Younger Scientists 2017 and gave a prize lecture entitled "Exciting Crystals(!): Studying Molecular Switches by in-situ Photocrystallography" at the BCA Spring Meeting in Lancaster. The award was in recognition of her published work in the area of chemical crystallography - her particular focus on photocrystallographic studies of linkage isomers.

Dr Lynne Thomas talked to BBC Bristol ahead of her participation in the National Soapbox Science Festival in Bristol on Sunday 7th June. This festival brought 12 inspirational local female scientists to the streets to share their research, engage the public and inspire the next generation of scientists.

Lynne's discussion topic at the well-attended event was “Why does Chocolate go off? Adventures with crystals”.

To hear Lynne talk about her love of chocolate (and crystals too!) in a bit more depth and the importance of Soapbox Science for women, click the following link:

Mat Bryant, one of the team's PhD students, has a photograph accepted into the Images of Research 2015 competition.

Mat had this to say about the picture: "In the Metastable Materials group at the University of Bath we develop new smart-materials with switchable properties. This might be colour, shape, magnetic properties, or in the case of this image - luminescence.

The tubes in this image actually all contain the same substance but by simply changing the dilution we can shift the colour of light produced to any part of the rainbow and by getting it just right, we can even produce white light!

The way this works is by something called ‘excimer emission’, where molecules emit a different colour in pairs than they do on their own. By adjusting the dilution we can increase or reduce the likelihood of two molecules meeting and forming pairs, and so tune the colour of the light."

This year's images will be featured at a preview event in The Edge at the University of Bath on Wednesday 13th May where awards for best image, description and overall entry will be presented. Best of luck to Mat!
