  1. 1. New applications and developments of field-asymmetric ion mobility spectrometry - mass spectrometry (FAIMS-MS)

    Författare :Axel Mie; Centrum för analys och syntes; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; triazine; enantiomer; ion focusing; ion mobility; FAIMS; DMS; axial ion inlet;

    Sammanfattning : Field asymmetric ion mobility spectrometry (FAIMS), also commonly termed differential mobility spectrometry (DMS), is a gas-phase ion separation technology. FAIMS exploits differences in high-electric-field to low-electric-field ion mobility ratios to discriminate between ion species. LÄS MER

  4. 3. Light scattering and absorption in pigmented coatings : Theory and experiments

    Författare :William E. Vargas; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; Solid State Physics; fasta tillståndets fysik;

    Sammanfattning : Radiative transfer models are used to describe optical properties of polymericthick films containing spherical inhomogeneities with sizes comparable to thewavelength of the incident radiation. From Lorenz-Mie theory various parametersrelated to elastic light scattering and absorption by single particles are calculated, i.e. LÄS MER

  5. 4. Surface Plasmon Photonics: From Optical Properties of Nanoparticles to Single Molecule Surface-enhanced Raman Scattering

    Författare :Hongxing Xu; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanoparticles; nanostructures; Mie theory; surface plasmon; surface-enhanced Raman scattering; single molecule spectroscopy;

    Sammanfattning : With the rapid development of nanoscience and nanotechnology, surface plasmon photonics using metal nanoparticles and nanostructures gain increasing interest, not only for fundamental scientific studies, but also for electronic, optical, and sensor applications. In the nanoscale, the physical and chemical properties of metallic particles, especially their optical properties, strongly depend on size and shape, as well as on surrounding media and structures.
