摘要： The present disclosure provides a nanotube solution being treated with a molecular additive, a nanotube film having enhanced adhesion property due to the treatment of the molecular additive, and methods for forming the nanotube solution and the nanotube film. The nanotube solution includes a liquid medium, nanotubes in the liquid medium, and a molecular additive in the liquid medium, wherein the molecular additive includes molecules that provide source elements for forming a group IV oxide within the nanotube solution. The molecular additive can introduce silicon (Si) and/or germanium (Ge) in the liquid medium, such that nominal silicon and/or germanium concentrations of the nanotube solution ranges from about 5 ppm to about 60 ppm.

摘要： The present disclosure provides methods for removing defects nanotube application solutions and providing low defect, highly uniform nanotube fabrics. In one aspect, a degassing process is performed on a suspension of nanotubes to remove air bubbles present in the solution. In another aspect, a continuous flow centrifugation (CFC) process is used to remove small scale defects from the solution. In another aspect, a depth filter is used to remove large scale defects from the solution. According to the present disclosure, these three methods can be used alone or combined to realize a low defect nanotube application solutions and fabrics.

摘要： The present disclosure provides scalable nanotube fabrics and methods for controlling or otherwise adjusting the nanotube length distribution of a nanotube application solution in order to realize scalable nanotube fabrics. In one aspect of the present disclosure, one or more filtering operations are used to remove relatively long nanotube elements from a nanotube solution until nanotube length distribution of the nanotube solution conforms to a preselected or desired nanotube length distribution profile. In another aspect of the present disclosure, a sono-chemical cutting process is used to break up relatively long nanotube elements within a nanotube application solution into relatively short nanotube elements to realize a pre-selected or desired nanotube length distribution profile.

摘要： A method for arranging nanotube elements within nanotube fabric layers and films is disclosed. A directional force is applied over a nanotube fabric layer to render the fabric layer into an ordered network of nanotube elements. That is, a network of nanotube elements drawn together along their sidewalls and substantially oriented in a uniform direction. In some embodiments this directional force is applied by rolling a cylindrical element over the fabric layer. In other embodiments this directional force is applied by passing a rubbing material over the surface of a nanotube fabric layer. In other embodiments this directional force is applied by running a polishing material over the nanotube fabric layer for a predetermined time. Exemplary rolling, rubbing, and polishing apparatuses are also disclosed.

摘要： A payment device and method and system for using the payment device is described capable of utilizing a pre-authorized amount on existing infrastructure, including POS terminals or for using offline pre-paid products on this infrastructure. The updates for the pre-authorized or offline prepaid products can be sent by the issuer and applied by the card contemporaneously with the card's processing of the issuer authentication data but without requiring any additional bytes in the issuer authentication data. The updates performed by the issuer can be larger and more extensive than could be achieved by using any available space in the issuer authentication data.

摘要： This disclosure is directed to optical data path systems that enable unidirectional and bidirectional transmission of optical signals between nodes of a multi-node system such as a multiprocessor system. In one aspect, an optical data path system includes an optical device layer connected to nodes of a multi-node system and a controller. The optical device layer includes a waveguide network of waveguide branches optically connecting each node of the multi-node system to every other node of the multi-node system, resonators disposed adjacent to the waveguide branches, and detectors disposed adjacent to waveguide branches of the waveguide network. Each detector is electronically connected to a node of the multi-node system. The resonators are operated by the controller to control the path of optical signals sent between the nodes of the multi-node system.
