Abstract:
A flexible air-metal battery is described. The battery may include a flexible oxygen permeable substrate, an air cathode that is in contact with the substrate, a flexible electrolyte in electrical contact with the air cathode, a flexible metal anode in contact with the flexible electrolyte such that the flexible metal anode is not in contact with the air cathode, and a plurality of flexible current collectors. At least one of the current collectors is in contact with the air cathode and at least one of the flexible current collectors is in contact with the metal anode.
Abstract:
Methods and systems for concentrating and allowing for separation of nanoparticles from fluids use acoustically driven nanoparticle concentrators which have an aerogel as the reflecting material and include tuning capabilities to alter the location at which the particles are being concentrated.
Abstract:
An electrochemical cell includes an anode containing calcium hexaboride, where the electrochemical device is an alkaline cell or an air cathode cell.
Abstract:
A method includes directing an ion beam at a tissue. Ions of the ion beam can include positron emitters. The ions can ionize at least a portion of the tissue and the positron emitters can irradiate the at least a portion of the tissue.
Abstract:
Metal nanoparticles are assembled in interrupted metal strands or other structures of characteristic dimensions and orientation to generate a giant dielectric response through a modified GE effect. Careful selection and modification of the host material and synthesis also leads to low dielectric breakdown voltages. In addition, the high dielectric composite material is employed in material configurations that are more scalable for industrial and consumer applications.
Abstract:
Nano-antennas with a resonant frequency in the optical or near infrared region of the electromagnetic spectrum and methods of making the nano-antennas are described. The nano-antenna includes a porous membrane, a plurality of nanowires disposed in the porous membrane, and a monolayer of nanospheres each having a diameter that is substantially the same as a diameter of the nanowires. The nanospheres are electrically in series with the nanowires.
Abstract:
A device for managing the heat load of one or more photovoltaic cells and methods for fabricating and using the device are disclosed. The device may include a base unit and an overhang unit that overhangs at least a portion of the base unit. The overhang unit may also be in thermal communication with the base unit. One or more photovoltaic cells may be in thermal communication with the base unit, and the overhang unit may overhang the photovoltaic cells as well. The overhang unit may be composed of a material that may reduce the amount of radiation having energy less than the band-gap energy from reaching the cells. The device may also include an upright section between the base unit and the overhang unit that is in thermal communication with both the base and the overhang.
Abstract:
Separation layers, usable in devices for converting radiation energy to electrical energy, allow at least some of the components of the devices to be separated from one another for disposal thereof. A separation layer may be interposed between and bonded to adjoining layers, such that chemical etching is used so as to degrade the separation layer(s) to thereby allow separation of a conversion layer of the conversion device from a substrate of the conversion device. Once released, the conversion layer, separation layer and the substrate may be disposed of more efficiently and economically, including proper disposal of hazardous waste, and recycling of materials which may be reusable.
Abstract:
Systems and methods for processing materials for a recycling workstream are disclosed. The system may include one or more sorting surfaces on which sortable items may be placed. Illumination sources may be provided to illuminate both the items and the sorting surface(s). A variety of sensor systems may also be provided. The outputs of the sensor systems may be supplied to a computing system for determining the composition of the items and their location on the sorting surface(s). The computing system may also control the surface(s), illumination sources, and sensor systems. Additionally, the system may include one or more augmented reality interface devices used by sorters at the sorting facility. The computing system may communicate data streams to the augmented reality interfaces to provide the users augmented reality sensations. The sensations may give the users information and instructions regarding how to sort the items into one or more sorting bins.
Abstract:
Technologies are generally described for a window and a method for cooling a room including a window. In some examples, the window may include a first pane and a second pane spaced from and in optical communication with the first pane defining a generator chamber. An evaporator chamber may be disposed in the window with a pressure so that the evaporator chamber is effective to receive heat from the room and boil a refrigerant to produce a first vapor. An absorber chamber may be effective to receive and condense the first vapor on an absorbent to produce a solution. The generator chamber may be effective to receive heat through the first pane, receive the solution and heat the solution to produce a second vapor. A condenser chamber may be effective to receive the second vapor and cool the second vapor to produce the refrigerant.
