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.

Patent number: 7824649Abstract: 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.Type: GrantFiled: April 28, 2006Date of Patent: November 2, 2010Assignees: Tsinghua University, Hon Hai Precision Industry Co., Ltd.Inventors: Kai-Li Jiang, Zhuo Chen, Shou-Shan Fan

Publication number: 20100221351Abstract: 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.Type: ApplicationFiled: March 1, 2010Publication date: September 2, 2010Applicant: UNIVERSITY OF SOUTH CAROLINAInventor: Xiaoming He
