  1. 41. Raman and Fluorescence Spectroscopy of Single Molecules and Metal Particles

    Författare :Jerk Bjerneld; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser-induced; single-molecule spectroscopy; surface-enhanced Raman scattering; nanoparticles;

    Sammanfattning : Technological and conceptual advances have led to the realization of single-molecule spectroscopy. This permit detailed investigations of heterogeneous systems in fields ranging from condensed matter physics to biochemistry. It was recently discovered that surface-enhanced Raman scattering (SERS) can be used to study single molecules. LÄS MER

  3. 42. Towards new sensors for prostate cancer detection : combining Raman spectroscopy and resonance sensor technology

    Författare :Stefan Candefjord; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Engineering for Healthcare; Medicinsk teknik för hälsovård;

    Sammanfattning : Prostate cancer (PCa) is the most common male cancer in Europe and the US, and only lung and colorectal cancer have a higher mortality among European men. In Sweden, PCa is the most common cause of cancer-related death for men. LÄS MER

  4. 43. Spontaneous and stimulated X-ray Raman scattering

    Författare :Yu-Ping Sun; Faris Gel'mukhanov; Vincenzo Carravetta; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; resonant X-ray scattering; resonant Auger scattering; rotational Doppler broadening; XFEL pulse; Atomic and molecular physics; Atom- och molekylfysik; Spectroscopy; Spektroskopi;

    Sammanfattning : The present thesis is devoted to theoretical studies of resonant X-ray scattering and propagation of strong X-ray pulses. In the first part of the thesis the nuclear dynamics of different molecules is studied using resonant X-ray Raman and resonant Auger scattering techniques. LÄS MER

  5. 44. Laser induced effects in carbon nanotubes : implications for Raman characterization of functionalized systems

    Författare :David Olevik; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; Fysik;

    Sammanfattning : Carbon nanotubes (CNTs) have attracted attention over the past decade because of their outstanding mechanical and electronic properties. These tiny tubular shells made of carbon atoms can be metallic or semiconducting and while having diameters of only about one nanometer (10-9 m), they can be up to centimeters in length, making them quasi one-dimensional (molecular wires).

  7. 45. Prostate cancer sensor : combining Raman spectroscopy and tactile resonance technology

    Författare :Morgan Nyberg; Anders Eklund; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical Engineering for Healthcare; Medicinsk teknik för hälsovård;

    Sammanfattning : Prostate cancer (PCa) is the most common cancer type among men in Sweden. The most prevalent curative treatment for PCa is radical prostatectomy (RP), i.e., complete surgical removal of the prostate. LÄS MER
