  1. 1. Infrared spectroscopy : Method development and ligand binding studies

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

    Sammanfattning : 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. LÄS MER

  2. 2. Infrared Emittance of Paper : Method Development, Measurements and Application

    Författare :Caroline Hyll; Lars Mattsson; Hannes Vomhoff; Carl-Gustaf Ribbing; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Emittance; Emissivity; Thermography; Paper; Sheet; Papermaking; Paper mechanics; Moisture; Material properties; Reflectance; Transmittance; Absorptance; Infrared; Mid-wavelength infrared; MWIR; Long-wavelength infrared; LWIR; Angle-resolved; Directional;

    Sammanfattning : Thermography is a non-destructive technique which uses infrared radiation to obtain the temperature distribution of an object. The technique is increasingly used in the pulp and paper industry. To convert the detected infrared radiation to a temperature, the emittance of the material must be known. LÄS MER

  3. 3. Infrared studies : Method development and binding of ligands to pyruvate kinase

    Författare :Saroj Kumar; Andreas Barth; Christopher Wharton; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Biophysics; biofysik;

    Sammanfattning : Infrared spectroscopy is a valuable technique for the study of ligand induce change in biomolecules. Our development of a dialysis accessory to attenuated total reflection infrared spectroscopy makes this technique more universal for ligand binding studies. LÄS MER

  4. 4. Infrared spectroscopy : a tool for protein characterization

    Författare :Chenge Li; Andreas Barth; Silvia Maria Doglia; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; biokemi; Biochemistry;

    Sammanfattning : Infrared (IR) spectroscopy, which belongs to vibrational spectroscopy, detects the vibrations of molecules, for example, proteins. The absorption of the peptide group gives rise to 9 characteristic bands in the infrared region, named A, B, I-VII, with a decreasing energy or wavenumber (cm-1). LÄS MER

  5. 5. Computational infrared spectroscopy : Calculation of the amide I absorption of proteins

    Författare :Cesare Michele Baronio; Andreas Barth; Sander Woutersen; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; infrared spectroscopy; FTIR; simulation; calculation; amide I; transition dipole coupling; F matrix; protein; amyloid β; oligomers; β-helix; Biophysics; biofysik;

    Sammanfattning : Infrared spectroscopy is an important technique that allows to retrieve structural information from the analysis of absorption spectra. The main application of infrared spectroscopy within life science is the study of the amide I band, which is correlated with protein backbone conformation and, consequently, with the secondary structure of proteins.
