20140192950 | COMPUTED TOMOGRAPHY SYSTEM WITH DYNAMIC BOWTIE FILTER - A CT apparatus for scanning an object is provided. An x-ray source is provided, wherein the x-ray source provides a collimated x-ray beam with a cross-section with a length and thickness. A plurality of wedges is provided between the source and object. An actuator is connected to the wedges for moving the wedges substantially perpendicular to the length of the cross-section of the collimated x-ray beam. An x-ray detector is located on an opposite side of the object from the x-ray source and is for detecting x-rays that pass through the object and the plurality of wedges. A gantry rotates the x-ray source, the plurality of wedges, and the x-ray detector around an axis of rotation. | 07-10-2014 |
20130123458 | CATALYTIC POLYMERIZATION OF POLYMERS CONTAINING ELECTROPHIIC LINKAGES USING NUCLEOPHILIC REAGENTS - The disclosure relates to methods and materials useful for polymerizing a monomer. In one embodiment, for example, the disclosure provides a method for polymerizing a monomer containing a plurality of electrophilic groups, wherein the method comprises contacting the monomer with a nucleophilic reagent in the presence of a guanidine-containing catalyst. The methods and materials of the disclosure find utility, for example, in the field of materials science. | 05-16-2013 |
