  • Patent number: 9982145
    Abstract: This invention pertains to a composition that can be used to heal cracks in plastics and other substrates. In the present invention, a composition comprising nanotubes, healing agent(s), and end caps for the nanotubes may be used to heal crack(s) as they begin to occur. With the composition, the healing agent(s) are contained within the nanotubes, and a reaction releases the healing agent(s) after the end caps can be removed from the nanotubes. This invention also includes a method of preparing a composition for healing cracks in plastics and other substrates. For this method, the healing agent(s) are filled inside of the nanotubes, and then end caps are bound onto the ends of the nanotubes. After a reaction occurs to remove the end caps and release the healing agent(s), the cracks within the substrate may then be healed.

  • Publication number: 20170373359
    Abstract: An integrated coolant bottle assembly includes a reservoir configured for use in a thermal system. Examples of such thermal systems include a cooling/heating system of a battery powered electric vehicle, electric power generators (e.g., motor-based systems), other physical plant installations, etc. Such a reservoir includes a first section and a second section. The second section is joined to the first section at a reservoir interface thereby forming the reservoir that is configured for storage and/or flow of a liquid medium. The first section may include an integrated channel that provides a pathway for the flow of the liquid medium. The reservoir may also include a component interface configured to facilitate connection of a component thereto (e.g., a pump, a battery pump, a powertrain pump, a chiller, a heater, a filter, an aerator, a valve, a connector, a fan, or a radiator).

  • Publication number: 20170365895
    Abstract: An energy storage system includes multiple cells, a heat pipe, a first heat transfer channel, and a second heat transfer channel. Each cell has a first end with anode and cathode terminals and a second end opposite the first end with the multiple cells arranged so that the second ends are aligned. The heat pipe has a U-shape and includes an evaporation portion having a flat evaporation surface facing the second ends of the multiple cells, a first condensation portion oriented substantially perpendicular to the evaporation portion, and a second condensation portion oriented substantially perpendicular to the evaporation portion. The first condensation portion is at a first end of the evaporation portion and the second condensation portion is at a second end of the evaporation portion. The first heat transfer channel abuts the first condensation portion and the second heat transfer channel abuts the second condensation portion.

  • Patent number: 9842956
    Abstract: One embodiment of the invention can provide a system for fabricating a photovoltaic structure. During fabrication, the system can form a sacrificial layer on a first side of a Si substrate; load the Si substrate into a chemical vapor deposition tool, with the sacrificial layer in contact with a wafer carrier; and form a first doped Si layer on a second side of the Si substrate. The system subsequently can remove the sacrificial layer; load the Si substrate into a chemical vapor deposition tool, with the first doped Si layer facing a wafer carrier; and form a second doped Si layer on the first side of the Si substrate.

  • Patent number: 9827602
    Abstract: A method of thermally servicing a solvent-refining column comprises: running a closed-loop water-steam system past a top and bottom of a first column, the first column containing at least a solvent and impurities; boiling pressurized water in the closed-loop water-steam system to steam using first heat from the top of the first column; compressing the steam in the closed-loop water-steam system to a higher temperature; and providing second heat to the first column by condensing the steam at the bottom of the first column after compression.

  • Patent number: 9828039
    Abstract: Impact protection structures for vehicles are described. An impact protection structure includes a support structure of the vehicle, an interior rail coupled to the support structure, and an exterior rail coupled to the interior rail. The exterior rail has an inboard boundary wall positioned between an upper mounting region and a lower mounting region. The upper and the lower exterior mounting region of the exterior rail are coupled to an upper and a lower mounting region of the interior rail. At least a portion of the inboard boundary wall is spaced apart from an outboard wall of the interior rail such that when the exterior rail is impacted by a blunt-object barrier, the inboard boundary wall of the exterior rail deforms, thereby damping energy of the impact at the exterior rail and arresting crack propagation between the exterior rail and the interior rail.
