  • 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 ...

  • A Raman-based endoscopic strategy for multiplexed molecular imaging

    Endoscopic imaging is an invaluable diagnostic tool allowing minimally invasive access to tissues deep within the body. It has played a key role in screening colon cancer and is credited with preventing deaths through the detection and removal of precancerous polyps. However, conventional white-light endoscopy offers physicians structural information without the biochemical information that would ...

  • Identification of forensic fabrics using a portable Raman spectrometer

    At a crime scene, a police officer collects a fiber sample that may prove to be invaluable evidence in identifying a criminal or exonerating an innocent person. While FTIR has been used for analysis in the past, the strong absorption of the fabric or the glass slide where it is mounted makes the spectrum very hard to interpret. In recent years, Raman spectroscopy has been studied extensively for ...

  • 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 ...

    Performance History and Discussion USW Utility Group who manages the Ft. Dodge Wastewater Treatment Plant selected In-Pipe Technology to reduce lagoon sludge levels and delay the lagoons' scheduled 2011 dredging event, as well as to improve process operation and efficiency. Secondary project objectives include the improvement of conditions in the City's collection system by removing fats, ...

  • Building analytical competence for geoscience students through use of Raman spectroscopy

    Introduction: Traditionally, a geologist's analytical toolkit consisted of a hand lens, rock hammer, acid bottle, magnet, and perhaps a polarizing light microscope back in the laboratory. In geoscience professions, these tools are increasingly being supplemented by field and laboratory instrumentation that utilizes spectroscopy. The availability of newly-developed, lower-priced ...
