Abstract: Polarized white light emitting devices are provided that have a substrate coated with a film of boron chains embedded in carbon nanotubes. An orientation of magnets adjacent the device polarizes and intensifies the light. Methods of making the devices, and methods of producing polarized white light are also provided.

Abstract: An embodiment relates to a photocatalytic composite material comprising (a) a first component that generates a photoexcited electron and has at least a certain minimum bandgap to absorb visible light and a structure that substantially prevents the recombination of the photoexcited electron and a hole; (b) a second component that adsorbs/absorbs an oxide of carbon; and (c) a third component that splits the oxide of carbon into carbon and oxygen using the photoexcited electron.

Abstract: Photo-regenerable oxygen scavenging packaging is generally disclosed. Some example embodiments may comprise tantalum oxide and/or manganese oxide arranged to act as a photo-regenerable oxygen scavenger. The tantalum oxide, if present, may operate as an oxygen scavenger when the tantalum oxide exists as tantalum (IV) oxide. Subjecting the tantalum oxide to light may transform at least a portion of the tantalum oxide existing as tantalum (V) oxide to tantalum (IV) oxide. The manganese oxide, if present, may operate as an oxygen scavenger when the manganese oxide exists as manganese (II) oxide. Subjecting the manganese oxide to light may transform at least a portion of the manganese oxide existing as manganese (III) oxide to manganese (II) oxide. Some example containers may include a structure defining an interior volume and a photo-regenerable oxygen scavenger disposed in fluidic communication with the interior volume.

Abstract: “Green” cements, which can be carbon neutral or negative, can be prepared at lower temperatures (450° C.-500° C.) by utilizing feed compositions comprising (i) TiO2, TaOxNy, TiOxNy, RuO2, Pt, TaO, band gap materials, or a first mixture thereof; (ii) Al2O3; and (iii) Ca2SiO4, MgSiO2, MnSiO2, or a second mixture thereof; and spent wash with melanoidin as a binder.

Abstract: Technologies are generally described for a battery, a method for implementing a battery and a rechargeable battery system. In some examples, the rechargeable battery system includes a battery. The battery may include a first electrode including a tantalum component, a vanadium component and a boron component. The battery may further include a second electrode and an electrical insulator between the first and the second electrode. The battery system may include a housing, where the housing includes the first electrode, and where the housing is effective to communicate light and oxygen to the first electrode. A sensor may be disposed so as to be effective to detect a reaction of tantalum and oxygen in the housing and generate a reaction signal in response. A processor may be in electrical communication with the sensor and effective to receive the reaction signal and generate an indication based on the reaction signal.
