# gst-chem: growth by random fluctuations in a curvy fractal structure

<< The weaker interaction causes the molecules to slide past each other and dislocate during crystal growth, resulting in an unusual, irregular crystal. According to Guoquing Zhang, ‘at room temperature, there is a high probability that crystal growth will be dictated by random fluctuations, resulting in a curvy fractal structure’ >>

<< The  crystals  of  1-(4-methoxyphenyl)-3-(pyridin-2-yl)propane-1,3-dione exhibited  rarely  seen  curved  fractal  structures  under  an  optical microscope.  Weak  intermolecular  interactions  may  result  in  dislocation during  crystal  growth  and  thus  the  irregular  crystalline  structures.  The micrographs  of  the  crystals  were  exploited  for  their  artistic  value  and were  transferred  onto  fabrics  for  application  in  fashion  design. >>
