  • Highly dispersible carbon nanospheres in a polar solvent and methods for making same
    Patent number: 7666915
    Abstract: The particle sizes of agglomerates of carbon nanospheres are reduced by dispersing the carbon nanospheres in a polar solvent. The carbon nanospheres are multi-walled, hollow, graphitic structures with an average diameter in a range from about 10 nm to about 200 nm, more preferably about 20 nm to about 100 nm. Spectral data shows that prior to being dispersed, the carbon nanospheres are agglomerated into clusters that range in size from 500 nm to 5 microns. The clusters of nanospheres are reduced in size by dispersing the carbon nanospheres in the polar solvent (e.g., water) using a surface modifying agent (e.g., glucose) and ultrasonication. The combination of polar solvent, surface modifying agent, and ultrasonication breaks up and disperses agglomerates of carbon nanospheres.

  • Method and system for plasma-induced terahertz spectroscopy
    Patent number: 7652253
    Abstract: A method of analyzing a remotely-located object includes the step of illuminating at least a portion of a targeted object with electromagnetic radiation to induce a phase transformation in the targeted object, wherein the phase transformation produces an emitter plasma, which emits terahertz radiation. The method also includes the step of ionizing a volume of an ambient gas to produce a sensor plasma by focusing an optical probe beam in the volume and the step of detecting an optical component of resultant radiation produced from an interaction of the focused optical probe beam and the terahertz radiation in the sensor plasma. Detecting an optical component of the resultant radiation emitted by the sensor plasma facilitates detection of a characteristic fingerprint of the targeted object imposed onto the terahertz radiation produced as a result of the induced phase transformation.

  • System and method for walking an implantable medical device from a sleep state
    Patent number: 7650185
    Abstract: A system and method for waking up an implantable medical device (“IMD”) from a sleep state in which power consumption by the IMD is essentially zero. The IMD may be adapted to perform one or more designated measurement and/or therapeutic functions. In one embodiment, the IMD includes a wake-up sensor that is adapted to sense the presence or absence of a wake-up field generated by another IMD or an external device. The wake-up field may, in some embodiments, be an electromagnetic field, a magnetic field, or a physiologically sub-threshold excitation current (i.e., E-field). Upon sensing by the wake-up sensor of the wake-up field, other components of the IMD, which may include a controller, a sensing and/or therapy module, and/or a communications module, are awakened to perform one or more designated functions.

  • EVENT-BASED BATTERY MONITOR FOR IMPLANTABLE DEVICES
    Publication number: 20100010559
    Abstract: A remaining charge capacity of a battery having an initial charge capacity is monitored. The battery powers a remote implantable medical device (IMD) that includes an active state, during which the remote IMD performs at least one function, and an inactive state, during which the remote IMD performs no functions. An active state charge consumption is computed based on stored parameters associated with an operational charge consumption for each function, and an inactive state charge consumption is computed based on a leakage current associated with the inactive state and a time the remote IMD is in the inactive state. The active state charge consumption and inactive state charge consumption are subtracted from the initial charge capacity to determine the remaining charge capacity.

  • Method for manufacturing supported nanocatalysts having an acid-functionalized support
    Patent number: 7632774
    Abstract: Supported catalysts include an inorganic solid support such as silica that is functionalized to have inorganic acid functional groups attached thereto. The functionalization of the support material is optimized by (i) limiting the amount of water present during the functionalization reaction, (ii) using a concentrated mineral acid or derivative thereof, and/or (iii) increasing the reaction temperature and/or reaction pressure. The acid-functionalized support material serves as a support for a metal nanoparticle catalyst. The nanocatalyst particles are preferably bonded to the support material through an organic molecule, oligomer, or polymer having functional groups that can bind to both the nanocatalyst particles and to the support material. The supported catalysts can advantageously be used for the direct synthesis of hydrogen peroxide from hydrogen and oxygen feed streams.

  • Methods for manufacturing bi-metallic catalysts having a controlled crystal face exposure
    Patent number: 7601668
    Abstract: Improved bi-metallic nanocatalysts are manufactured using a control agent to produce nanoparticles having a controlled crystal face exposure. The bi-metallic nanocatalyst particles are manufactured in a two-step process. In a first step, nanocatalyst particles are manufactured using the control agent and the primary metal atoms. The primary metal atoms and the control agent are reacted to form complexed metal atoms. The complexed metal atoms are then allowed or caused to form nanoparticles. The nanoparticles formed in the first step using the control agent have a desired crystal face exposure. In a second step, the secondary metal atoms are deposited on the surface of the primary metal nanoparticles. The secondary catalyst atoms maintain the same crystal face exposure as the primary metal nanoparticles.
