20100151577 | QUANTUM DOT-BASED ENVIRONMENTAL INDICATORS - A detection method and indicator are disclosed that includes quantum dots that fluoresce under illumination of a first light having a first wavelength to indicate the presence of a predetermined condition, and in particular, a corrosion condition. The quantum dots are surrounded by a shell material that under normal conditions reflect the first light and reacts in the presence of the predetermined condition to permit the first light to illuminate the quantum dot to excite the quantum dot to emit a second light having a second wavelength, which when detected, indicates the presence of the predetermined condition. | 06-17-2010 |

20120156421 | OPTIMIZED FIBER SHAPES FOR IMPROVED OPTICAL PERFORMANCE - A composite article has an article surface and may comprise a plurality of fibers at least partially embedded in a matrix. Each fiber may have at least one base surface and a pair of side surfaces. The side surfaces may be oriented in non-perpendicular relation to the base surface. The fibers may be positioned in side-by-side relation to one another such that the side surfaces of each fiber are oriented substantially parallel to the side surfaces of the immediately adjacent fibers. | 06-21-2012 |
20130170020 | APPARATUS AND METHODS TO PROVIDE A SURFACE HAVING A TUNABLE EMISSIVITY - Apparatus and methods to provide a surface having a tunable emissivity are disclosed. An example apparatus includes an impedance layer comprising a layer of dielectric material to be attached to an electrically reflective ground plane, and a plurality of resonators arranged within the impedance layer, wherein an emissivity of the apparatus is based on a characteristic of the resonators. | 07-04-2013 |
20140014902 | Photodiode and Method for Making the Same - A method for manufacturing a photodiode including the steps of providing a substrate, solution depositing a quantum nanomaterial layer onto the substrate, the quantum nanomaterial layer including a number of quantum nanomaterials having a ligand coating, and applying a thin-film oxide layer over the quantum nanomaterial layer. | 01-16-2014 |
20140087172 | METHOD OF MANUFACTURING A COMPOSITE ARTICLE USING FIBERS HAVING OPTIMIZED SHAPES FOR IMPROVED OPTICAL PERFORMANCE - A method of manufacturing a composite article may include providing a plurality of fibers. At least a portion of the plurality of fibers may be substantially optically transparent. The method may further include forming the fibers with at least one base surface and a pair of side surfaces oriented in non-perpendicular relation to the base surface. The method may additionally include positioning the fibers in a layer in side-by-side relation to one another such that the side surfaces overlap one another when viewed along a direction normal to a plane of the layer. The method may also include embedding the fibers at least partially in a substantially optically transparent polymeric matrix. | 03-27-2014 |
20140202239 | BOND EVALUATION USING PIEZOCHROMIC FLUORESCENCE - A composite bonded structure with integral stress sensing and bond evaluation system incorporates a bonded structure having a first component, a second component and a layer of adhesive bonding the first and second components. The layer of adhesive includes multiple embedded fluorescing particles which emit a first spectral intensity in an unstressed condition and a second spectral intensity in a stressed condition. A bond evaluation apparatus is then employed for measuring spectral intensity. | 07-24-2014 |
