  • Patent number: 9006612
    Abstract: A method and device for creating a temperature gradient among a plurality of temperature gradient devices. Each device is formed of a first layer of conductive material having a top surface and a bottom surface. The first layer is adjacent to a second layer of conductive material and has electrical resistive heating properties. A power supply is used to provide a current flow through at least the first layer when the power supply is activated. When activated, the resulting current flow causes the second layer to heat and thus create a temperature gradient between the bottom surface of the second layer and the top surface of the first layer. Activation of the power supply is controlled by a control unit so that activation of adjacent temperature gradient devices is avoided for a predetermined time after activation of the first temperature gradient device.

  • Publication number: 20110108774
    Abstract: A thermoelectric nanocomposite is formed from homogeneous ceramic nanoparticles formed from at least one kind of tellurium compound. The ceramic nanoparticles have an average particle size from about 5 nm to about 30 nm and particularly to about 10 nm. The ceramic nanoparticles are coated with a particle coating in each case. The particle coating is formed from at least one layer of nanostructured, substantially intact carbon material. The nanocomposite may be formed by providing a precursor powder of homogeneous ceramic nanoparticles with at least one kind of a tellurium compound. A precursor coating of nanostructured, substantially intact carbon material is provided for the precursor nanoparticles. Heat treatment of the precursor powder generates the nanocomposite by conversion of the precursor coating into the particle coating.

  • Patent number: 7824649
    Abstract: This apparatus and method facilitate the synthesis of a single-wall carbon nanotube array. The apparatus includes a reactor, a local heating device, a gaseous carbon supplier, and a reactant gas supplier. The reactor is configured for receiving a catalyst in a reaction zone thereof. The local heating device is configured for selectively heating the reaction zone and/or the catalyst received thereat. The gaseous carbon supplier is configured for introducing gaseous carbon into the reactor from an upstream position of the reaction zone. The reactant gas supplier is configured for introducing a reactant gas containing a carbon source gas into the reactor. A densely aligned, single-wall carbon nanotube array can be achieved due to the proximity to the catalyst of the heating device and due to the gaseous carbon supplier.

    Abstract: In accordance with certain embodiments of the present disclosure, A method for intracellular delivery of cytotoxin in combination with cyoablation is provided. The method includes encapsulation of one or more cytotoxins in a thermally responsive nanocapsule by decreasing the temperature of the nanocapsule to increase the permeability of the nanocapsule whereby the one or more cytotoxins are sucked into or diffuse into the nanocapsule. The temperature of the nanocapsule is increased and the nanocapsule is delivered into a cell. Cryoablation is performed in proximity to the cell resulting in the release of the one or more cytotoxins from the nanocapsule into the cell.
