  • Publication number: 20140262806
    Abstract: A method and composition for producing a photoactive material including photocatalytic capped colloidal nanocrystals (PCCN) and plasmonic nanoparticles are disclosed. The PCCN may include a semiconductor nanocrystal synthesis and an exchange of organic capping agents with inorganic capping agents. Additionally, the PCCN may be deposited between the plasmonic nanoparticles, and may act as photocatalysts for redox reactions. The photoactive material may be used in a plurality of photocatalytic energy conversion applications, such as water splitting and CO2 reduction. By combining different semiconductor materials for PCCN and plasmonic nanoparticles, and by changing their shapes and sizes, band gaps may be tuned to expand the range of wavelengths of sunlight usable by the photoactive material. Higher light harvesting and energy conversion efficiency may be achieved.

  • Publication number: 20140099562
    Abstract: The present disclosure is directed towards the design of bipolar plates for use in conduction-cooled electrochemical cells. Heat generated during the operation of the cell is removed from the active area of the cell to the periphery of the cell via the one or more bipolar plates in the cell. The one or more bipolar plates are configured to function as heat sinks to collect heat from the active area of the cell and to conduct the heat to the periphery of the plate where the heat is removed by traditional heat transfer means. The boundary of the one or more bipolar plates can be provided with heat dissipation structures to facilitate removal of heat from the plates. To function as effective heat sinks, the thickness of the one or more bipolar plates can be determined based on the rate of heat generation in the cell during operation, the thermal conductivity (“k”) of the material selected to form the plate, and the desired temperature gradient in a direction orthogonal to the plate (“?T”).

  • Publication number: 20140097093
    Abstract: Methods and apparatuses for electrolysis that does not require the use of a transformer to operate. The apparatus comprises one or more electrolytic cells which comprise the number of intermediate electrodes sufficient to enable the cell or cells to operate at the rectified line voltage without any need for voltage regulation, or near the rectified line voltage with only some voltage regulation, such as less than 20% of the rectified line voltage. Such regulation is achieved by using a buck or boost converter rather than a transformer, and can be varied to accommodate fluctuations in the line voltage and/or conductivity of the electrolyte, or varied to produce different chemistries in the same apparatus.
