  • Sedimentary record of anthropogenic and biogenic polycyclic aromatic . . .
    TOC concentration profiles in cores from Richardson and San Pablo Bays are shown in Fig 3 a 1 and a 2, respectively Concentrations of organic carbon ranged from 7 4 to 11 2 mg g −1 dry sediment in Richardson Bay, and from 5 9 to 17 mg g −1 in San Pablo Bay The TOC profile in Richardson Bay probably indicates a relatively uniform input of organic carbon over the last century
  • Sediment chronology in San Francisco Bay, California, defined by
    Sediment chronologies based on radioisotope depth profiles were developed at two sites in the San Francisco Bay estuary to provide a framework for interpreting historical trends in organic compound and metal contaminant inputs At Richardson Bay near the estuary mouth, sediments are highly mixed by biological and or physical processes Excess 234 Th penetration ranged from 2 to more than 10 cm
  • Sedimentary record of anthropogenic and biogenic polycyclic aromatic . . .
    Dated sediment cores collected from Richardson and San Pablo Bays in San Francisco Bay were used to reconstruct a history of polycyclic aromatic hydrocarbon (PAH) contamination The sedimentary record of PAHs in Richardson Bay shows that anthropogenic inputs have increased since the turn of the century, presumably as a result of increasing urbanization and industrialization around the Bay Area
  • SOLAR ENERGY STORAGE REACTIONS INVOLVING METAL COMPLEXES
    Photochemical properties of transition metal complexes are discussed as they relate to possible schemes for energy storage Complexes of copper(I) with π-acceptor ligands have been used to sensitize isomerizations of organic molecules, and there is room for considerable further investigation in this area
  • Chem | Journal | ScienceDirect. com by Elsevier
    Chem, a sister journal to Cell, provides a home for seminal and insightful research and showcases how fundamental studies in chemistry and its sub-disciplines may help in finding potential solutions to the global challenges of tomorrow Chem publishes work from across the chemical sciences and at the interfaces between chemistry and other disciplines
  • Sediment chronology in San Francisco Bay, California . . . - ScienceDirect
    This paper presents sediment radionuclide profiles at two coring sites in the San Francisco Bay estuary: Richardson Bay near the estuary mouth and San Pablo Bay, about midpoint between the river delta and the ocean (Fig 1) Chronologies for recent sediments (<100 years) were derived from radionuclide profiles for evaluation of metal and organic contaminant profiles presented in subsequent
  • Assessment of methane emissions from a California landfill using . . .
    Methane flux and emissions were obtained at a California landfill concurrently using field measurements, inventory analyses, and modeling Measured fluxes ranged from −3 7 to 828 g m 2-day and generally decreased from daily to intermediate to final covers Soil covers with high-plasticity clay had the lowest fluxes
  • Electron-extracting system with enhanced photocatalytic hydrogen . . .
    Novel ternary Ni x P CuWO 4 ZnIn 2 S 4 hybrids combined Z-scheme heterojunction with Ohmic contact were synthesized for the first time and used as efficient visible-light-driven photocatalysts for hydrogen production Benefiting from the synergistic effect of the two junctions, the ternary hybrids with excellent electron-extracting capablilty, electron utilization and photostability exhibit
  • Boosting photocatalytic hydrogen production coupled with benzyl alcohol . . .
    The consumption of chemical fuels causes severe energy problems, so it is essential to find a clean and renewable energy source [1], [2] In recent years, photocatalytic hydrogen (H 2) production by water splitting has been considered to be an effective strategy to solve the energy crisis [3], [4] However, most researches focus on the half-reaction of H 2 production, which consumes holes by
  • A versatile strategy for broadening light absorption to ultraviolet . . .
    Photo-driven CO 2 conversion into high-value-added chemicals (such as CO, CH 4, HCOOH, and C 2+ chemicals) is recognized as an effective and eco-friendly strategy to address global warming and energy crisis [1], [2], [3] Metal-organic frameworks (MOFs) with semiconductor properties have garnered significant attention in photocatalysis due to their well-defined structures and tunable
