  • Caltech working to solve the world`s energy problems with the help of inVia

    Fossil fuels are the world's main fuel source for transportation, heating and generating electricity. As a by-product, high levels of CO2 are released into the atmosphere. With the drive for sustainable energy production, a method that generates easily-stored fuel from sunlight—and absorbs CO2—is a very attractive proposition. The California Institute of Technology ...

  • Raman frequency dispersion studies of substituted polythiophene films

    Styryl substituted terthiophene species have been used to produce neutral polythiophene species which show distinct Raman frequency dispersion. The polythiophene line B band shows dispersion values of: -0.12, -0.07, -0.1 cm−1 nm−1 for the phenyl, para-methoxy phenyl and para-cyano phenyl systems respectively. This is smaller than the dispersion values reported for polythiophene presumably because ...

  • Replacement of 130 ft Secondary Clarifiers at a 25 MGD wastewater treatment facility

    Challenge A municipal WWTP found that (2) of their secondary clarifiers were too rusted and corroded to properly function. A traditional clarifier refurbishment consisting of sandblasting and painting was not a viable option because one of the clarifier rake arms had recently broken due to its poor condition. The plant engineers decided that a clarifier rebuild was necessary to ensure ...

  • Syncrude oilsands tailings pond, Ft. McMurray, Alberta, Canada

    Syncrude Canada produces a large part of Canada's crude oil supply. The company processes about 225,000 bbl/day. The oil produced is used for jet and automobile fuel, home heating oil, plastics and other consumer synthetics. Crude oil is produced through a process of mining, extracting and upgrading bitumen. A rich supply of bitumen is contained in the Athabasca oil sands deposit in northern ...

  • Fabrication of uniform substrate based on silver nanoparticles decorated glycidyl methacrylate-ethylene dimethacrylate porous material for ultrasensitive surface-enhanced Raman scattering detection

    Surface-enhanced Raman scattering (SERS) in practical application and theoretical research mostly depends on the performance of the SERS substrate. In this study, a new SERS substrate which is based on inverted self-assembly of Ag nanoparticles (AgNPs) on glycidyl methacrylate-ethylene dimethacrylate (GMA-EDMA) porous material is developed. The characterization results show the GMA-EDMA material ...

  • Aeration system improves mixing, oxygenation, & maintenance

    When its brush rotor system failed, the city of Franklin, LA, dccidcd to replace it with an Airc-02 Triton aeration/mixer system, which about equaled the ongoing costs of refurbishing die rotors. The aerators met all the city's needs and a year later, city officials purchased more of the aerators for its second ditch. Back in 2000, Franklin's wastewater treatment plant consisted of an activated ...

  • Mobile systems provide solar energy in northern climates
