20080277596 | Impact Indicating Microcapsules - The present disclosure is directed at an impact indictor that may be coated on a structure to detect impacts thereon. The indicator may be provided within microcapsules. Upon rupture of the microcapsules, the indicator may be exposed to a pH activator, wherein the indicator may then exhibit fluorescence upon exposure to electromagnetic energy. | 11-13-2008 |
20090044744 | Thermal Sensitive Material - An impact-resistant thermal sensitive material comprising at least one indicator dispersed throughout a heat-sensitive matrix material is provided. An article comprising the impact-resistant thermal sensitive material undergoes a permanent color change when exposed to a pre-determined temperature. | 02-19-2009 |
20100083873 | Encapsulation Of Active Agents For On-Demand Release - The present disclosure relates to a method of forming microcapsules. The method may include combining an active agent in a first solvent S | 04-08-2010 |
20100187439 | Fluorescent Monitoring Of Microcapsule Oxidation - The present disclosure relates to microcapsules that include a shell material and a core material. The core material of the microcapsules contains an environmentally sensitive luminescent colorant which exhibits characteristics of an emitted wavelength bandwidth, a peak intensity for emission and a time for luminescence decay, one or more of the characteristics capable of changing upon exposure to a given environment, and a luminescent standard which exhibits characteristics of an emitted wavelength bandwidth, a peak intensity for emission and a time for luminescence decay, one or more of the characteristics do not change upon exposure to said given environment. | 07-29-2010 |
20100297446 | Layer By Layer Modification Of Microcapsules With Inorganic Materials - The present disclosure relates to a microcapsule and a method of forming a microcapsule which may be used for oxygen sensitive materials. The microcapsule may comprise a shell encapsulating a core material having a surface, wherein the shell comprises a first organic or inorganic polyelectrolyte providing a plurality of cationic or anionic charges. This may then be followed by forming a first layer comprising an inorganic or organic polyelectrolyte on the microcapsule surface, where the polyelectrolyte of the first layer provides a plurality of cationic or anionic charges, opposite to the charge of the shell polyelectrolyte. This may then be followed by forming a second layer comprising a second organic or inorganic polyelectrolyte providing a plurality of cationic or anionic charges, opposite to the charge of the first layer polyelectrolyte. | 11-25-2010 |
20110015568 | Dry To Wet Injector - The present disclosure relates to an apparatus and method for combining a solid particulate with a solvent prior to an injection protocol within an injector device. The solid particulate may be a pharmaceutical compound and the microcapsules contain a solvent for such particulate. Upon application of pressure, the microcapsules may be configured to burst and release the solvent, thereby dispersing and/or partially dissolving the particulate. The injector therefore allows for the use of relatively unstable pharmaceutically active compounds in a device that requires relatively long storage times and the use of pharmaceutical compounds that are relatively stable in the dry state. | 01-20-2011 |
20120274616 | Electrophoretic Display Using Fibers Containing a Nanoparticle Suspension - A composite textile for generating an electrophoretically driven image. The textile has at least three layers. An outer (relative to an observer of the image) electrode layer is made from a transparent and electrically conductive material. A fibermat layer is under the outer electrode layer, and comprises a mat of one or more fibers, each fiber being transparent and dielectric and having a hollow core that contains a fluid suspension of particles (typically nanoparticles) of at least two color types. A pattern layer is under the fiber mat layer, and has an arrangement of features made from an electrically conductive material. When voltage is applied to the pattern layer, the particles respond by migrating toward the outer electrode or pattern layer, depending on their charge. | 11-01-2012 |
20130270726 | Encapsulation Of Active Agents For On-Demand Release - The present disclosure relates to a method of forming microcapsules. The method may include combining an active agent in a first solvent S | 10-17-2013 |
20140202541 | Encapsulaton Of High Temperature Molten Salts - The present disclosure relates to a method of encapsulating microcapsules containing relatively high temperature phase change materials and the microcapsules so produced. The microcapsules are coated with an inorganic binder, film former and an inorganic filler. The microcapsules may include a sacrificial layer that is disposed between the particle and the coating. The microcapsules may also include an inner coating layer, sacrificial layer and outer coating layer. The microcapsules are particularly useful for thermal energy storage in connection with, e.g., heat collected from concentrating solar collectors. | 07-24-2014 |
