Patent number: 8616873Abstract: A micro-conformal nanoimprint lithography template includes a backing layer and a nanopatterned layer adhered to the backing layer. The elastic modulus of the backing layer exceeds the elastic modulus of the nanopatterned layer. The micro-conformal nanoimprint lithography template can be used to form a patterned layer from an imprint resist on a substrate, the substrate having a micron-scale defect, such that an excluded distance from an exterior surface of the micron-scale defect to the patterned layer formed by the nanoimprint lithography template is less than a height of the defect. The nanoimprint lithography template can be used to form multiple imprints with no reduction in feature fidelity.Type: GrantFiled: January 26, 2011Date of Patent: December 31, 2013Assignee: Molecular Imprints, Inc.Inventors: Michael N. Miller, Frank Y. Xu, Nicholas A. Stacey

Patent number: 8617452Abstract: Disclosed herein are materials, and methods for creating materials, that does not require heat to create a functional construction material. One purpose of the materials and methods disclosed herein is, at least, to provide industries, such as the construction industry, with a product that significantly reduces the generation of carbon dioxide during production, unlike Portland Cement and typical geopolymer cements. Further, another advantage of the invention is that it utilizes basic processes and materials that may be incorporated into existing production facilities and methodologies. A further purpose is to increase the quality of the product by reducing damage from, for example, exposures to adverse climatic conditions (such as extreme or variable weather), or damaging chemicals such as chlorides, sulfates, acids, or the like.Type: GrantFiled: August 15, 2011Date of Patent: December 31, 2013Assignee: SRMZ Technical, Inc.Inventor: Rodney W. Zubrod

Patent number: 8609326Abstract: The present invention is directed to a method that attenuates, if not avoids, heating of a substrate undergoing imprint lithography process and the deleterious effects associated therewith. To that end, the present invention includes a method of patterning a field of a substrate with a polymeric material that solidifies in response to actinic energy in which a sub-portion of the field is exposed sufficient to cure the polymeric material is said sub-portion followed by a blanket exposure of all of the polymeric material associated with the entire field to cure/solidify the same.Type: GrantFiled: March 13, 2008Date of Patent: December 17, 2013Assignee: Molecular Imprints, Inc.Inventors: Sidlgata V. Sreenivasan, Byung-Jin Choi

Patent number: 8580183Abstract: Methods of producing collection tubes are presented. The methods include providing a separator substance that can rapidly polymerize in a short time to a desired hardness and disposing the separator substance within the lumen of the tube. The separator substance is formulated to have a density between an average density of a serum fraction of whole blood and a cell-containing fraction of whole blood, and to be flowable with whole blood. Upon centrifugation of a tube having blood, the separator substance forms a barrier between the whole blood fractions. The barrier rapidly hardens forming a solid barrier when triggered by a suitable energy source.Type: GrantFiled: November 19, 2012Date of Patent: November 12, 2013Assignee: The Regents of the University of CaliforniaInventor: Jane F.
