20130224934 | NANOTUBE SOLUTION TREATED WITH MOLECULAR ADDITIVE, NANOTUBE FILM HAVING ENHANCED ADHESION PROPERTY, AND METHODS FOR FORMING THE NANOTUBE SOLUTION AND THE NANOTUBE FILM - 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. | 08-29-2013 |
20130243954 | NANOTUBE SOLUTIONS WITH HIGH CONCENTRATION AND LOW CONTAMINATION AND METHODS FOR PURIFIYING NANOTUBE SOLUTIONS - Solutions of carbon nanotubes and methods for purifying the solutions are provided. The methods include mixing, for example, at least one complexing agents, at least one ionic species, and/or at least one buffer oxide etch (BOE) with a liquid medium containing carbon nanotubes and different types of contaminants, such as metal impurities, amorphous carbon, and/or silica particles, and performing a filtration process to the liquid medium so as to remove or reduce the contaminants in the liquid medium. As a result, carbon nanotube solutions of low contaminants are produced. In some embodiments, the solutions of this disclosure include a high concentration of carbon nanotubes and are substantially free from metal, amorphous carbon, and/or silica impurities. | 09-19-2013 |
20140045316 | SWITCHING MATERIALS COMPRISING MIXED NANOSCOPIC PARTICLES AND CARBON NANOTUBES AND METHODS OF MAKING AND USING THE SAME - An improved switching material for forming a composite article over a substrate is disclosed. A first volume of nanotubes is combined with a second volume of nanoscopic particles in a predefined ration relative to the first volume of nanotubes to form a mixture. This mixture can then be deposited over a substrate as a relatively thick composite article via a spin coating process. The composite article may possess improved switching properties over that of a nanotube-only switching article. A method for forming substantially uniform nanoscopic particles of carbon, which contains one or more allotropes of carbon, is also disclosed. | 02-13-2014 |
20140329430 | Low Defect Nanotube Application Solutions and Fabrics and Methods for Making Same - 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. | 11-06-2014 |
20150086771 | SCALABLE NANOTUBE FABRICS AND METHODS FOR MAKING SAME - 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. | 03-26-2015 |

20090211785 | PRINTED CIRCUIT BOARD WITH EDGE MARKINGS - A multilayer printed circuit board may include traces that are printed on selected layers of the board so that the traces extend to the edge of the corresponding layer. When the layers are assembled together, the ends of the traces may be viewable on a side of the printed circuit board. The traces may be arranged to convey information. For example, trace ends may be readable as one or more binary words, as alphanumeric characters or as a bar code. | 08-27-2009 |
20090273079 | SEMICONDUCTOR PACKAGE HAVING PASSIVE COMPONENT BUMPS - A semiconductor package includes contact bumps configured as passive circuit components. One or more contact bumps of the semiconductor package may be formed or configured as pull-up resistors, pull-down resistors, capacitors or inductors. | 11-05-2009 |
20110001231 | SEMICONDUCTOR PACKAGE HAVING NON-UNIFORM CONTACT ARRANGEMENT - A semiconductor package has a non-uniform contact arrangement in which clustered contacts (e.g., a group of ground contacts, a group of power contacts, and/or a group of heatslug contacts) are placed closer together than I/O contacts. In one embodiment, I/O contacts near a cluster have a pitch in at least one direction that is larger than other I/O contacts. A local increase in the pitch of I/O contacts may be used to increase the line width and/or spacing of traces that fan out from corresponding pads on a printed circuit board. | 01-06-2011 |
