20080221294 | RESOL BEADS, METHODS OF MAKING THEM, AND METHODS OF USING THEM - Resol beads are disclosed prepared by reaction of a phenol with an aldehyde, with a base as catalyst, in the presence of a colloidal stabilizer, and optionally a surfactant. The resol beads have a variety of uses, and may be thermally treated and carbonized to obtain activated carbon beads. | 09-11-2008 |
20120271028 | RESOL BEADS, METHODS OF MAKING THEM, AND METHODS OF USING THEM - Resol beads are disclosed that are prepared in high yield by reaction of a phenol with an aldehyde, with a base as catalyst, a colloidal stabilizer, and optionally a surfactant. The resol beads have a variety of uses, and may be thermally treated and carbonized to obtain activated carbon beads. | 10-25-2012 |
20120325231 | FILTERS HAVING IMPROVED DEGRADATION AND METHODS OF MAKING THEM - Degradable filters are disclosed, as well as methods of making them, that include the steps of applying a plasticizer containing a photoactive agent to cellulose ester fibers to obtain plasticized cellulose ester fibers; and forming the plasticized cellulose ester fibers into a filter. The cellulose ester fibers may comprise cellulose acetate, the plasticizer may be triacetin, and the photoactive agent may include a number of types of titanium dioxide, for example mixed phase titanium dioxide particles. The filters are useful, for example, in preparing cigarette filters. | 12-27-2012 |
20120325233 | CELLULOSE ESTERS HAVING MIXED-PHASE TITANIUM DIOXIDE PARTICLES FOR IMPROVED DEGRADATION - Degradable cellulose esters are disclosed that have incorporated therein or thereon mixed-phase titanium dioxide particles. The esters may be in the form of filters prepared by applying a plasticizer, having the mixed-phase titanium dioxide particles dispersed therein, to cellulose ester fibers to obtain plasticized cellulose ester fibers; and thereafter forming the plasticized cellulose ester fibers into a filter. Alternatively, the particles may be added to the dope from which the fibers are spun, or blended with a cellulose ester intended for molded articles. | 12-27-2012 |

20080285827 | METHOD FOR IMAGE PROCESSING AND RECONSTRUCTION OF IMAGES FOR OPTICAL TOMOGRAPHY - A method for reconstructing three-dimensional (3D) tomographic images. A set of pseudo-projection images of an object is acquired. Error corrections are applied to the set of pseudo-projection images to produce a set of corrected pseudo-projection images. The set of corrected pseudo-projection images are processed to produce (3D) tomographic images. | 11-20-2008 |
20090208072 | 3D IMAGING OF LIVE CELLS WITH ULTRAVIOLET RADIATION - A method for 3D imaging of cells in an optical tomography system includes moving a biological object relatively to a microscope objective to present varying angles of view. The biological object is illuminated with radiation having a spectral bandwidth limited to wavelengths between 150 nm and 390 nm. Radiation transmitted through the biological object and the microscope objective is sensed with a camera from a plurality of differing view angles. A plurality of pseudoprojections of the biological object from the sensed radiation is formed and the plurality of pseudoprojections is reconstructed to form a 3D image of the cell. | 08-20-2009 |
20100279268 | METHOD FOR CREATING PERFUSABLE MICROVESSEL SYSTEMS - A method for creating networks of perfusable microvessels in vitro. Cells including cell types capable of sprouting are seeded | 11-04-2010 |
20100322494 | Focal Plane Tracking for Optical Microtomography - An optical tomography system for imaging an object of interest including a light source for illuminating the object of interest with a plurality of radiation beams. The object of interest is held within an object containing tube such that it is illuminated by the plurality of radiation beams to produce emerging radiation from the object containing tube, a detector array is located to receive the emerging radiation and produce imaging data used by a mechanism for tracking the object of interest. | 12-23-2010 |
