May the Fourth Be With You! Our postdoc, Mark, just had a paper from his PhD published in Analytical Chemistry. In this work, Mark and his collaborators from the University of Bath, UK used a millifluidic flow system to study the crystallization of two pharmaceutical compounds with in situ X-ray powder diffraction. Their results revealed the phase stability of these compounds in solution and demonstrated the power of well-designed fluid sample environments for studying dynamic materials synthesis processes.
