Patent number: 8431084Abstract: A crystallizer for the evaporative production of phenol-BPA adduct crystals is provided that achieves more uniform crystal growth while suppressing undesired crystal nucleation. The crystallizer includes a cylindrical vessel; a draft tube concentrically disposed within the cylindrical vessel such that an annular space is defined between the vessel and tube; an impeller that circulates liquid in the vessel through the draft tube and the annular space, and a plurality of nozzles mounted around an inner wall of said cylindrical vessel that introduce an evaporative coolant into the vessel. Each of the nozzles includes a discharge end disposed between about 30% and 60% of a radial extent of the annular space, and is located below an upper end of the draft tube a distance of between about 50% to 150% of the diameter of the vessel. Such a nozzle arrangement provides a consistent and uniform concentration of coolant across the surface of the boiling zone that prevents or at least reduces unwanted crystal nucleation.Type: GrantFiled: June 23, 2010Date of Patent: April 30, 2013Assignee: Badger Licensing LLCInventor: Stephen W. Fetsko

Patent number: 8382896Abstract: High throughput screening of crystallization of a target material is accomplished by simultaneously introducing a solution of the target material into a plurality of chambers of a microfabricated fluidic device. The microfabricated fluidic device is then manipulated to vary the solution condition in the chambers, thereby simultaneously providing a large number of crystallization environments. Control over changed solution conditions may result from a variety of techniques, including but not limited to metering volumes of crystallizing agent into the chamber by volume exclusion, by entrapment of volumes of crystallizing agent determined by the dimensions of the microfabricated structure, or by cross-channel injection of sample and crystallizing agent into an array of junctions defined by intersecting orthogonal flow channels.Type: GrantFiled: January 29, 2007Date of Patent: February 26, 2013Assignees: California Institute of Technology, The Regents of the University of CaliforniaInventors: Carl L. Hansen, Stephen R. Quake, James M. Berger

Patent number: 8361224Abstract: The present invention relates to colloidal photonic crystals using colloidal nanoparticles and a method for the preparation thereof, wherein by adding a viscoelastic material into a solution containing the colloidal nanoparticles when preparing the colloidal photonic crystals, a uniform volume contraction occurs due to the elasticity of the viscoelastic material even when a nonuniform volume contraction occurs while drying a dispersion medium in the colloidal solution. Thus, it is possible to prepare 2 or 3 dimensional colloidal photonic crystals of large scale with no defects in less time.Type: GrantFiled: June 21, 2010Date of Patent: January 29, 2013Assignee: LG Chem, Ltd.Inventors: Young-jun Hong, Sang-hyuk Im
