20130320305 | Memory Device with a Double Helix Biopolymer Layer and Fabricating Method Thereof - The present invention relates to a write-once and read-many-times memory device and the fabricating method thereof. The structure of the memory device comprises: a substrate, a first electrode, a double helix biopolymer layer and a second electrode, and a plurality of metal nanoparticles are distributed in the double helix biopolymer layer. The first electrode is disposed on the substrate, the double helix biopolymer layer is disposed on the first electrode and the substrate, and the second electrode is disposed on the double helix biopolymer layer. When illuminating, the memory device will produce a low-conductivity state and high-conductivity state for writing data. Later, when a voltage is applied to the first electrode and the second electrode, the data will be read. | 12-05-2013 |

20090217840 | CELLULAR OR ORGANELLE-ENTRAPPED NANOPARTICLES - The invention provides tissue marking pigment or dye particle retained within a tissue cell, the cellular cytoplasm, or one or more intracellular organelles. Also, the invention provides nanoparticles, which are phagocytosed, engulfed or otherwise entrapped by cells. | 09-03-2009 |
20090311295 | PARTICLES WITH HIGH UNIFORM LOADING OF NANOPARTICLES AND METHODS OF PREPARATION THEREOF - Methods to produce polymeric microparticles containing nanoparticles such, as pigments, dyes and other chromophores for cosmetic use, plastic surgery therapeutic use, and tattoos have been developed. The microparticles contain within the polymer a very uniform dispersion of dye particles. The methods by which the particles are made ensure a homogeneous mixture and high loading. The microparticles are made using air, one of a number of known methods such as phase inversion, solvent evaporation, and melt processing. The improvement is in the use of a method that makes, a stable dispersion of the nanoparticles in the liquid polymer before formation of the microparticles. This is achieved through selection of appropriate solvent, optionally including surfactant, and then subjecting the dispersion to mechanical processing that stabilizes the dispersion within the polymer solvent, so that the nanoparticles remain suspended for at least thirty minutes, in some cases two hours to 48 hours, sometimes up to three months. The mechanical processing can be sonication and/or production of shear forces, for examples, resulting from use of an open blade or rotor stator mixer or milling with a concentric shaft, at a speed such as between 5000 and 25,000 RPM. | 12-17-2009 |

20100261029 | MULTI-PHASE PARTICULATES, METHOD OF MAKING, AND COMPOSITION CONTAINING SAME - Provided is a multi-phase particulate having a dispersed phase component dispersed in and bound to a bulk phase component. The dispersed phase component includes a metal, a metal oxide, an organometallic compound, salts thereof, and/or mixtures thereof, and the bulk phase component includes an inorganic material different from the dispersed phase component. The dispersed phase component is present in an amount ranging from 0.5 to 60 percent by weight based on total combined weight of the dispersed phase component and the bulk phase component. Related methods, compositions and composites also are provided. | 10-14-2010 |
20130071682 | MULTI-PHASE PARTICULATES, METHOD OF MAKING, AND COMPOSITION CONTAINING SAME - Provided is a method of preparing a multi-phase particulate. The method includes: (1) blending together (a) a dispersed phase component of a metal, a metal oxide, an organometallic compound, salts thereof, and/or mixtures thereof, and (b) a bulk phase component of an inorganic material different from the dispersed phase component to form an admixture; and (2) dry-milling and/or compressing the admixture for a time and at a pressure sufficient to disperse the dispersed phase component in and bind the dispersed phase component to the bulk phase component, thereby forming a multi-phase particulate. Coating compositions including the multi-phase particulate also are provided. | 03-21-2013 |
20140272434 | COATING COMPOSITIONS COMPRISING CYCLIC CARBONATE AMINE RESINS - The present disclosure describes cyclic carbonate-amine resin coating compositions including an amino functional silicon resin component, where the cyclic carbonate-amine resin coating displays improved oxidation resistance and durability. The coating compositions are isocyanate free and may be cured a low temperatures to provide a durable coating. In specific embodiments, the described coating compositions may be used as a mono-coat on a surface of an article, without any undercoating or primer layers. | 09-18-2014 |
