Publication number: 20240115781Abstract: Systems and apparatuses for blood oxygenation are disclosed. A system includes a first layer defining a plurality of banks of first channels each extending in a first direction. The plurality of banks of first channels are configured to receive blood via a trunk channel. The system includes a second layer defining a bank of second channels extending in a second direction. The bank of second channels are configured to receive oxygen. The first direction is different from the second direction. The system includes a membrane disposed between the first layer and the second layer and configured to cause the oxygen to permeate from the second layer to the first layer to oxygenate the blood.Type: ApplicationFiled: October 3, 2023Publication date: April 11, 2024Applicant: The Charles Stark Draper Laboratory, Inc.Inventors: Brett Isenberg, Else Vedula, David Sutherland, Diana Lewis, Jose Santos, WeiXuan Lai, Ernie Kim, Beau Landis, Jeffrey Borenstein, Bryan Teece, Samuel Blumenstiel, Joseph Urban

Patent number: 10145627Abstract: A nanotube-based insulator is provided having thermal insulating properties. The insulator can include a plurality of nanotube sheets stacked on top of one another. Each nanotube sheet can be defined by a plurality of carbon nanotubes. The plurality of carbon nanotubes can be configured so as to decrease normal-to-plane thermal conductivity while permitting in-plane thermal conductivity. A plurality of spacers can be situated between adjacent nanotube sheets so as to reduce interlayer contact between the nanotubes in each sheet. The plurality of spacers can be ceramic or alumina dots or provided by texturing the nanotube sheets.Type: GrantFiled: March 31, 2014Date of Patent: December 4, 2018Assignee: NANOCOMP TECHNOLOGIES, INC.Inventors: David S. Lashmore, Diana Lewis

Publication number: 20150183642Abstract: The present invention relates to systems and methods for generating nanoscopically aligned carbon nanotubes in yarns, tapes and sheets. Some embodiments relate to methods and systems to allow in situ alignment of the tubes within the growth chamber. In particular, processes for in situ alignment include: (1) gas flow alignment using gas lenses introduced within the reaction tube, (2) electrostatic alignment using electrostatic lenses surrounding the reaction tube, (3) gas flow alignment by convergent flow within the reaction tube, (4) placing catalysts on a fixed substrate and flowing reaction gas parallel to the substrate. Other embodiments involve post processing of the CNT material in order to align the materials once it has been produced.Type: ApplicationFiled: December 1, 2014Publication date: July 2, 2015Inventors: David S. Lashmore, Mark Schauer, Diana Lewis, Thomas Van Vechten, David Degtiarov

Publication number: 20120312343Abstract: Systems for producing electrical energy from heat are disclosed. The system may include a carbon-nanotube based pathway along which heat from a source can be directed. An array of thermoelectric elements for generating electrical energy may be situated about a surface of the pathway to enhance the generation of electrical energy. A carbon nanotube-based, heat-dissipating member may be in thermal communication with the array of thermoelectric elements and operative to create a heat differential between the thermoelectric elements and the pathway by dissipating heat from the thermoelectric elements. The heat differential may allow the thermoelectric elements to generate the electrical energy. Methods for producing electrical energy are also disclosed.Type: ApplicationFiled: April 12, 2012Publication date: December 13, 2012Applicant: Nanocomp Technologies, Inc.Inventors: Tom VanVechten, David S.

Patent number: 6508979Abstract: A method for fabricating or prototyping a nanoscale object is disclosed. The method includes defining a sequence of nanolayers that represent the nanoscale object, constructing a current nanolayer on a first surface, and depositing a sacrificial layer to cover the first surface but not the nanolayer. The nanolayer represents a slice of the nanoscale object. The nanolayer and the sacrificial layer provide a second surface on which a next nanolayer is constructed. The above construction and deposition steps are repeated if the next nanolayer is not the last nanolayer. The method also includes removing the sacrificial layers to produce the nanoscale object.Type: GrantFiled: June 30, 2000Date of Patent: January 21, 2003Assignee: University of Southern CaliforniaInventors: Aristides A.
