  • Publication number: 20090221088
    Abstract: Binding an analyte can cause a change in fluorescence emission of a sensor. The change in fluorescence can be related to the amount of analyte present. The sensor can include a semiconductor nanocrystal linked to a fluorescent moiety. Upon excitation, the fluorescent moiety can transfer energy to the semiconductor nanocrystal, or vice versa.

  • Patent number: 6863781
    Abstract: Embodiments for the invention include a process for the production of hydrogen comprising a protic solution, a photocatalyst capable of a two-electron reduction of hydrogen ions; and a coproduct trap. The embodiment includes exposing the reaction medium to radiation capable of photoexciting the photocatalyst to produce hydrogen. The protic solution may comprise at least one of hydrohalic acid, a silane, and water, and the hydrohalic acid may be hydrochloric acid, hydrogen bromide, hydrogen fluoride or hydrogen iodide. The present application also describes novel transition metal compounds. Embodiments of the compounds include a compound comprising two transition metal atoms, wherein the transition metal atoms are in a two-electron mixed valence state and at least one transition metal is not rhodium; and at least one ligand capable of stabilizing the transition metal atom in a two-electron mixed valence state.

  • Publication number: 20020110180
    Abstract: Temperature-sensing compositions can include an inorganic material, such as a semiconductor nanocrystal. The nanocrystal can be a dependable and accurate indicator of temperature. The intensity of emission of the nanocrystal varies with temperature and can be highly sensitive to surface temperature. The nanocrystals can be processed with a binder to form a matrix, which can be varied by altering the chemical nature of the surface of the nanocrystal. A nanocrystal with a compatibilizing outer layer can be incorporated into a coating formulation and retain its temperature sensitive emissive properties.

  • Patent number: 6065454
    Abstract: The performance of an internal combustion engine is optimized utilizing an electrically controlled driver which is located relative to the intake port to excite the intake charge at a selected frequency, duration and power level which depends on the engine operating condition. The purpose of this excitation is to control combustion by optimizing large scale recirculation patterns of the intake charge within the combustion chamber. In particular, this device will provide the effect of optimizing volumetric efficiency at wide open throttle and minimize fuel consumption and emissions at part throttle. An electronic engine controller varies the operation of the drive device as a function of engine operating conditions. The driver excites the intake charge at a frequency of about 5 to 1000 times of the engine speed.
