Publication number: 20110095245Abstract: A method for making fire retardant material including fire retardant cellulosic insulation. The method includes an arrangement for adding one or more feedstocks and a fire retardancy chemical compound to a common blend tank prior to feedstock drying. The one or more feedstocks may include at least one virgin pulp stock feed and at least one recycled material stock feed. The amount and type of both the virgin feedstock and the recycled material feedstock is selectable. Old newsprint (ONP) may be one type of recycled material feedstock. Another suitable type of recycled material feedstock is old corrugated containers (OCC). The method further includes retaining the fiber feedstock and the chemical compound together for enough time to ensure adherence or impregnations of enough of the chemical to the fibers after the drying process. Fluffing or fiberizing of the treated fibers may be accomplished under less severe conditions than ordinarily employed when making conventional cellulose insulation.Type: ApplicationFiled: October 22, 2010Publication date: April 28, 2011Applicants: Green Comfort Safe, Inc., University of Maine System Board of TrusteesInventors: Richard W.

Publication number: 20110091711Abstract: Methods and apparatuses for forming carbon nanostructures from a polymer mixture. The methods include the steps of mixing the pre-formed polymer with a liquid to form a polymer mixture, freezing the polymer mixture at an effective freezing rate greater than or equal to 103 Kelvin per second to form a polymer cast within the frozen liquid, separating the polymer cast from the frozen liquid by sublimating the frozen liquid, and carbonizing the polymer cast to form a carbon nanostructure. Variations of these methods are included in the scope of the invention and produce materials with varying properties. Through control of the freezing process, the nanomorphology of the resultant structure may be modulated. Nanostructures formed according to these methods are also claimed.Type: ApplicationFiled: October 20, 2010Publication date: April 21, 2011Applicant: University of Maine System Board of TrusteesInventors: David J.

Patent number: 7880149Abstract: A microscopy system is configured for creating 3D images from individually localized probe molecules. The microscopy system includes a sample stage, an activation light source, a readout light source, a beam splitting device, at least one camera, and a controller. The activation light source activates probes of at least one probe subset of photo-sensitive luminescent probes, and the readout light source causes luminescence light from the activated probes. The beam splitting device splits the luminescence light into at least two paths to create at least two detection planes that correspond to the same or different number of object planes of the sample. The camera detects simultaneously the at least two detection planes, the number of object planes being represented in the camera by the same number of recorded regions of interest. The controller is programmable to combine a signal from the regions of interest into a 3D data.Type: GrantFiled: June 29, 2010Date of Patent: February 1, 2011Assignees: The Jackson Laboratory, University of MaineInventors: Joerg Bewersdorf, Manuel F.
