  1. 1. X-ray-induced intermolecular reactions in mixed clusters

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Astrid Bergman; [2022]
    Keywords : molecular cluster; biophysics; X-ray;

    Abstract : The aim of this project was to study what mixed cluster fragments were formed in the interaction between radiation and H2O-CO2 clusters formed by adiabatic expansion, both experimentally and using simulations. The experiment was done using a mass spectrometer at the MAX IV synchrotron facility and by studying the time-of-flight of the ionic fragments. READ MORE

  3. 2. Studying the Dissociation Dynamics of Carbon Dioxide

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Author : Claudiu Bulbucan; [2017]
    Keywords : Physics and Astronomy;

    Abstract : Small molecules, and their fragmentation to smaller constituents upon excitation, are often used to understand how the bonds in a molecule are formed and how they break. One of such widely studied model molecule is CO2. This study aims at extending the knowledge of dissociation of carbon dioxide by measuring also the negatively charged fragments. READ MORE

  4. 3. Single photon double valence ionization of methyl monohalides

    University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Author : Andreas Roos; [2014]
    Keywords : Double photoionization; methyl halide; time-of-flight magnetic bottle spectrometer; coincidence measurement;

    Abstract : This thesis is based on experimental results from measurements on methyl halides at a photon energy corresponding to the He IIβ emission line. Double ionization processes involving the valence electrons of the molecules CH3F, CH3Cl and CH3I are studied by means of a magnetic bottle TOF-PEPECO spectrometer. READ MORE

  5. 4. Photon time-of-flight and continuous-wave near-infrared-spectroscopy of human skeletal muscle tissue; a comparative study

    University essay from Lunds universitet/Atomfysik; Lunds universitet/Matematisk fysik

    Author : Alfi Shaharin; [2013]
    Keywords : Photon time-of-flight spectrometer; pTOFS; Tissue Saturation; StO2; and CW-NIRS; Physics and Astronomy;

    Abstract : The focus of this thesis is to perform a comparative study between two noninvasive optical techniques: Photon Time-of-flight Spectroscopy (pTOFS) and a Continuous-wave NIRS system for measuring muscle tissue oxygen saturation. INVOS 5100C (Manufactured in 2011, Serial Number 11-10269, Produced by Somanetics Troy, MI 48084 USA) is such a CW-NIRS system that provides tissue oxygenation using continuous wave Near Infrared Spectroscopy technique and widely used in the hospitals.
