  • Patent number: 8263410
    Abstract: Disclosed is an innovative method for detecting metal ions based on selective plasmonic resonance energy transfer between metal-ligand complexes and a single nanoplasmonic particle as a probe. The selective plasmonic resonance energy transfer occurs if a resonance frequency matching condition between the single nanoplasmonic particle and the metal-ligand complexes is satisfied.

  • Patent number: 8252098
    Abstract: A device for filtering nanoparticulate matter below 300 nm in size from ambient air within a defined enclosed space comprises at least one filter medium containing at least one filter material, and a fan or blower, which blows or draws the air through the filter medium does so with sufficiently low air velocity in the filter medium that the air has a long residence time in the filter medium, during which time adhesive encounters between nanoparticulate matter and the solid phase of the filter material are highly probable. This air velocity is also being sufficiently low to ensure that, once adhesion has taken place, kinetic de-adhesion by the air flow is highly improbable. Such a device allows to keep the nanoparticle count inside the enclosed space kept below 5000/cc, equivalent to ‘natural woodland’, even though external levels may exceeded 200,000/cc: the removal of nanoparticles by cleaning making this <2.5% the external count.

  • Patent number: 8236095
    Abstract: A vacuum-pressure swing absorption concentrator includes a motor driven compressor having pressure and vacuum heads that are connected to a pressure reservoir and a vacuum reservoir respectively. The pressure and vacuum reservoirs are selectively and alternately interconnected in sequence through a main valve to a pair of nitrogen filtering sieve beds. A controller operates the valve to alternately and cyclically interconnect the sieve beds to the pressure and vacuum reservoirs respectively. During each cycle, a respective bed is pressurized and enriched oxygen is produced and delivered to a tank for use by a patient. At the same time, the other bed is evacuated through the vacuum reservoir. A crossover valve delivers oxygen from a pressurized bed to an evacuated bed to facilitate purging of impurities previously collected in the evacuated bed.

At least an additive material selected from inhibitor additives, anti-foam agents, stabilizers, metal scavengers, metal contaminant removers, metal passivators, and sacrificial materials, in an amount of less than 1 wt. % of the heavy oil feedstock, is added to at least one of the contacting zones. In one embodiment, the additive material is an anti-foam agent. In another embodiment, the additive material is a sacrificial material for trapping heavy metals in the heavy oil feed and/or deposited coke, thus prolonging the life of the slurry catalyst.
