Abstract: A super-semiconductor (SSC), semiconductor devices including the SSC, and methods for making the SSC. The SSC includes a bimetallic nanostructured array having a substrate and a nanoshell array disposed on the substrate. The nanoshell array is defined by a plurality of non-close-packed, non-conductive, core bodies disposed on the substrate, a first metal layer disposed on the non-conductive core bodies and on the substrate in areas located between adjacent non-conductive core-bodies, and at least a second metal layer disposed on the first metal layer, wherein the second metal is different than the first metal. The bimetallic nanostructured array exhibits p-type or n-type metal conductivity above a transition temperature, and in embodiments, exhibits resistivity in a range of 10?8-10?7 ohm*m at a temperature of 300K+/?40K.

Abstract: The present invention provides a method of capturing circulating tumor cells (CTCs) from a subject without using a cancer biomarker. The method comprises contacting a test sample with a carbon nanotube (CNT) sponge. The test sample comprises cells from a small amount of peripheral blood from a subject after removal of plasma and lysis of erythrocytes. The cells in the test sample comprise CTCs from the subject. The CNT sponge is free of an agent specific for a cancer biomarker.

Abstract: A flexible silicon anode includes a flexible substrate, a layer of silicon with a thickness of 1 ?m or less adhered to the flexible substrate, and a current collector in contact with the layer of silicon. A lithium ion battery cell includes a flexible silicon anode, a current collector in contact with the layer of silicon; a lithium cathode; a separator between the silicon anode and the lithium cathode; an electrolyte in contact with the silicon anode and the lithium cathode; and an electrical connection between the silicon anode and the lithium cathode. Forming the flexible silicon anode can include etching a silicon-on-insulator structure to form a silicon layer on the silicon substrate, treating the silicon layer, contacting the treated silicon layer with a flexible substrate, and separating the flexible substrate and the silicon substrate, thereby transferring the treated silicon layer from the silicon substrate to the flexible substrate.

Abstract: A supercapacitor comprising a cathode, an anode, a first single-walled carbon nanotube (SWNT) film electrode adjacent the cathode, a second SWNT film electrode adjacent the anode, and separator disposed between the first and second electrodes. The SWNT film electrodes may be manufactured by a non-filtration process comprising depositing the SWNT film on a foil via CVD; separating the SWNT film from the foil; heating the SWNT film; treating the SWNT film with an acid solution; washing the SWNT film; and excising the electrodes from the SWNT film.

Abstract: Long, macroscopic nanotube strands or cables, up to several tens of centimeters in length, of aligned single-walled nanotubes are synthesized by the catalytic pyrolysis of n-hexane using an enhanced vertical floating catalyst CVD technique. The long strands of nanotubes assemble continuously from ropes or arrays of nanotubes, which are intrinsically long. These directly synthesized long nanotube strands or cables can be easily manipulated using macroscopic tools.
