摘要:
Solid-state colorimetric biosensors having sensory groups and interdendritic cross-linking segments of alternating conjugated double and triple bonds are prepared by intermolecular polymerization of diacetylene-functionalized dendritic polymer precursors. The polymerization process may be used to form solid films that are capable of indicating the presence of an analyte by a detectable change in color. The disclosed solid-state calorimetric biosensors may exhibit excellent stability at elevated temperatures and in the presence of organic solvents, and due to the dendritic architecture and high density of sensing functionality achieve high sensitivity to analytes.

The present invention relates to surface modification of reverse osmosis membranes to introduce antifouling properties without compromising the separation properties of the original membranes. This approach utilizes: providing a coated membrane surface having enhanced hydrophilic characteristics that prevents the biofoulants from settling; have a surface that consists of hydrophilic brushes that unsettle any biofoulants that get through; and having antimicrobial ions present in the membrane coatings and able to remove or minimize any remaining biofoulants without leaching into the permeate. These coatings are made using dendritic polymers such as hyperbranched polymers or dendrimers.

In some embodiments, color and contrast enhancement video processing may be done in one shot instead of adjusting one of color and contrast enhancement, then the other, and then going back to the first one to readjust because of the second adjustment. In some embodiments, global lightness adjustment, local contrast enhancement, and saturation enhancement may be done at the same time and in parallel. Lightness adjustment improves visibility of details for generally dark or generally light images without changing intended lighting conditions in the original shot, and is used to enhance the range of color/saturation enhancement. Local contrast enhancement done in parallel improves visual definition of objects and textures and thus local contrast and perceived sharpness.

This invention concerns a solid polymer matrix for use as non-focal optical power limiting polymeric materials. This matrix contains: (1) a hyperbranched polymer family, especially HB-PCS OR HB-PU, HB-PUSOX or PC; (2) one or more of RSA dye, MPA dye, azo dye or DMNPAA; 3) CNT and 4) a self-focusing component.This solid polymer matrix provides efficient protection from laser beam damage along with its self-focusing mechanism.

The present invention provides a method and computer-readable medium for searching for programming objects on a computer system. Under one aspect of the invention, optional search attributes are used to order a list of references to found programming objects. Under a second aspect of the invention, object attributes that are stored outside of a static attribute storage area are inspected during the search for programming objects. Under a third aspect of the invention, different sets of object data are allowed to reference the same programming object class, and different objects of a single programming object class may be initialized in different ways so that they exhibit different attributes.

This invention concerns a polymer coating material composition (PCM) comprising as components a Polymer Matrix, carbon nanotubes (CNT) as optical power limiters (OPL), and carbon-rich molecules. One aspect of the invention is where the Polymer Matrix is a hyperbranched polymer, such as a hyperbranched polycarbosiloxane polymer. Another aspect of the invention is where the CNT is a short multiwall carbon nanotube (sMWNT). A further aspect of the invention is where the carbon-rich molecules are triethoxysilyl anthracene derivatives.The composition wherein the ratio in weight percent of Polymer Matrix to CNT to carbon-rich molecule is from 94:3:3 to 99.8:0.1:0.1.The composition can further contain one or more of multi-photon absorbers (MPA) chromophores or reverse saturable absorbers (RSA) chromophores.These compositions can be used as: a) a film, b) a coating, c) a liquid, d) a solution, or e) a sandwiched film between two transparent substrates.

For each colour, the method comprises the following steps: —converting the first set of colour coordinates (R0, G0, B0)R representing this colour into a first set of visual tristimulus values (X0, Y0, Z0) representing said colour as perceived by a first observer when displayed using a first set of primaries, —converting said first set of visual tristimulus values (X0, Y0, Z0) into a second set of visual tristimulus values (Xi, Yi, Zi) representing the same colour as perceived by a second observer, —converting said second set of visual tristimulus values (Xi, Yi, Zi) into a second set of colour coordinates (Ri, Gi, Bi)C representing said colour as perceived by said second observer when displayed using a second set of primaries.
