BIWIC 2019 – 26. International Workshop on Industrial Crystallization. Copyright: Adrian Flood
Crystallization is a vital process for the modern chemical industry. The International Workshop on Industrial Crystallization (BIWIC) promotes the international exchange and collaboration in industrial crystallization research. This cover illuminates the meaning behind the conference's dodecahedral logo (top right). Top left: Morphology of a hexamethylenetetramine (HMT) crystal with HMT molecules shown based on data from L. N. Becka et al., Proc. R. Soc. Lond. 1997, A273, 435–454. The image was produced using Mercury (C. F. Macrae et al., J. Appl. Cryst. 2020, 53, 226–235). Top right: The logo for BIWIC is a rhombic dodecahedron, such as the structure of HMT. Bottom left: SEM image of a typical HMT crystal (courtesy of P. Pantaraks). Bottom right: An interesting feature of HMT is its retrograde solubility. Displayed data shows the solubility in water (L. Wang et al., J. Chem. Eng. Data 2008, 53, 2907–2909).
