Small organic molecules have had a dramatic impact on our health and da ily life over the past century. Small molecule pharmaceuticals have increa sed human lifespans\, and organic pigments have expanded in use in textile s and displays. This impact is set to accelerate in the near future\, as s mall molecules are explored for novel applications such as organic electro nics\, or metal-organic frameworks for chemical separations\, catalysis an d sensing. One of the major barriers for using small organic molecules for new applications is the limited understanding we possess on how molecules aggregate together to form different crystal habits and phases. Different crystal structures and morphologies can have wildly varying physical\, ch emical and physiological properties. Thus\, if we do not control the cryst allization organic molecules\, we cannot predict its behavior for the afor ementioned applications. Understanding the crystallization process can als o help form metastable phases. These metastable phases can be more useful than the equilibrium phase for many applications. Metastable phases permit tunable optical bandgap for optoelectronics\, control over pore size and shape in metal organic frameworks (MOF)\, and increased bioavailability in pharmaceuticals. General methods used to create metastable phases\, like confinement or rapid cooling\, require small length scales and extreme rat es of heat and mass transfer. Moreover\, these processes need precise cont rol to get reliable results. This talk will focus on flow coating and micr ofluidic methods of controlling organic molecule and MOF crystallization c haracteristics\, and the use of these materials for various applications.< /p>\n DTSTART:20170330T150000Z LOCATION:Physics Building\, Room 313 SUMMARY:Understanding and Controlling Organic Molecule and Metal Organic Fr amework Crystallization END:VEVENT END:VCALENDAR
