  • Publication number: 20140230884
    Abstract: Disclosed herein is a system for stimulating an emission from at least one emitter, such as a quantum dot or organic molecule, on the surface of a photonic crystal comprising a patterned dielectric substrate. Embodiments of this system include a laser or other source that illuminates the emitter and the photonic crystal, which is characterized by an energy band structure exhibiting a Fano resonance, from a first angle so as to stimulate the emission from the emitter at a second angle. The coupling between the photonic crystal and the emitter may result in spectral and angular enhancement of the emission through excitation and extraction enhancement. These enhancement mechanisms also reduce the emitter's lasing threshold. For instance, these enhancement mechanisms enable lasing of a 100 nm thick layer of diluted organic molecules solution with reduced threshold intensity. This reduction in lasing threshold enables more efficient organic light emitting devices and more sensitive molecular sensing.

  • Publication number: 20140191435
    Abstract: The present invention is generally directed to nanocomposite thermoelectric materials that exhibit enhanced thermoelectric properties. The nanocomposite materials include two or more components, with at least one of the components forming nano-sized structures within the composite material. The components are chosen such that thermal conductivity of the composite is decreased without substantially diminishing the composite's electrical conductivity. Suitable component materials exhibit similar electronic band structures. For example, a band-edge gap between at least one of a conduction band or a valence band of one component material and a corresponding band of the other component material at interfaces between the components can be less than about 5 kBT, wherein kB is the Boltzman constant and T is an average temperature of said nanocomposite composition.

  • Publication number: 20140144397
    Abstract: A reformer-liquid fuel manufacturing system that utilizes an engine to generate hydrogen-rich gas is disclosed. The engine operates at very rich conditions, such as 2.5<?<4.0. In doing so, it creates an exothermic reaction, which results in the production of syngas. In addition, the system utilizes the energy from the exothermic reaction to rotate a shaft and also utilizes the heat in the syngas to heat the reactants. A mechanical power plant is in communication with the rotating shaft and can be used to produce oxygen, provide electricity or operate a compressor, as require. The hydrogen-rich gas is supplied to a chemical reactor, which converts the gas into a liquid fuel, such as methanol.

  • Publication number: 20140061486
    Abstract: A spectrometer can include a plurality of semiconductor nanocrystals. Wavelength discrimination in the spectrometer can be achieved by differing light absorption and emission characteristics of different populations of semiconductor nanocrystals (e.g., populations of different materials, sizes or both). The spectrometer therefore can operate without the need for a grating, prism, or a similar optical component. A personal UV exposure tracking device can be portable, rugged, and inexpensive, and include a semiconductor nanocrystal spectrometer for recording a user's exposure to UV radiation. Other applications include a personal device (e.g. a smartphone) or a medical device where a semiconductor nanocrystal spectrometer is integrated.
