  2. 1. Quantitative Surface Enhanced Raman Spectroscopy

    Author : Anders Lorén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; gold colloids; internal standard; surface enhanced Raman spectroscopy; SERS; PLS; PCA; SAM; quantitative;

    Abstract : Surface enhanced Raman spectroscopy (SERS) is a very attractive technique for detection of various organic and inorganic molecules due to its sensitivity and selectivity. The surface enhancement is achieved when the molecules of interest are on or in the vicinity of a metal surface, usually gold and silver. READ MORE

  4. 2. Type Ia Supernova Cosmology : Quantitative Spectral Analysis

    Author : Gastón Folatelli; Ariel Goobar; Enrico Cappellaro; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Supernova; Cosmology; Spectroscopy; Physics; Fysik;

    Abstract : Type Ia supernovae have been successfully used as standardized candles to study the expansion history of the Universe. In the past few years, these studies led to the exciting result of an accelerated expansion caused by the repelling action of some sort of dark energy. READ MORE

  5. 3. Quantitative Spectroscopy of Gas Phase Reactions at Elevated Temperatures

    Author : Joachim Walewski; Förbränningsfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fluiddynamik; Gaser; plasma; Maskinteknik; vibration and acoustic engineering; vacuum technology; hydraulics; vibrationer; vakuumteknik; statistical inference; Mechanical engineering; polarisation spectroscopy; diamond CVD; quantitative spectroscopy; hydraulik; gas phase kinetics; plasmas; fluid dynamics; Gases; Fysik; akustik; Physics; Fysicumarkivet A:2001:Walewski;

    Abstract : Gas phase reactions at elevated temperatures are versatile tools for material manufacturing and energy conversion. They are of great commercial interest, but they often entail hazardous impacts on the environment. There is consequently a pronounced need for the further develpment of processes utilising these types of reactions. READ MORE

  6. 4. Infrared spectroscopy : Method development and ligand binding studies

    Author : Saroj Kumar; Andreas Barth; Janos Mink; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Infrared; Ligand binding; method development; Biophysical chemistry; Biofysikalisk kemi; biofysik; Biophysics;

    Abstract : Infrared spectroscopy detects molecular vibrations and assesses the properties of molecules and their environment. It is a powerful technique to detect ligand induced changes in biomolecules as it has distinct signals and provides different levels of structural information. READ MORE

  7. 5. Quantitative diffuse reflectance spectroscopy : myocardial oxygen transport from vessel to mitochondria

    Author : Tobias Lindbergh; Tomas Strömberg; Henrik Ahn; Marcus Larsson; Lise Lyngsnes Randeberg; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : In the field of biomedical optics, diffuse reflectance spectroscopy (DRS) is a frequently used technique for obtaining information about the optical properties of the medium under investigation. The method utilizes spectral difference between incident and backscattered light intensity for quantifying the underlying absorption and scattering processes that affects the light-medium interaction.
