  2. 1. Creating and Probing Extreme States of Materials : From Gases and Clusters to Biosamples and Solids

    Author : Bianca Iwan; Nicusor Timneanu; Janos Hajdu; Stacey Sorensen; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; free-electron laser; ultrashort X-rays; non-equilibrium plasma; Coulomb explosion; isotope effect; hydrodynamic expansion; ion acceleration; high intensity lasers; ablation; time-of-flight spectroscopy; Fysik; Physics;

    Abstract : Free-electron lasers provide high intensity pulses with femtosecond duration and are ideal tools in the investigation of ultrafast processes in materials. Illumination of any material with such pulses creates extreme conditions that drive the sample far from equilibrium and rapidly convert it into high temperature plasma. READ MORE

  4. 2. Synchrotron radiation studies of gas phase molecules : from hydrogen to DNA sugars

    Author : Gemma Vall-llosera; Elisabeth Rachlew; Stacey Sorensen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; KTH thesis; synchrotron radiation; gas phase; bio molecules; Atomic and molecular physics; Atom- och molekylfysik;

    Abstract : This thesis summarises experimental results on the molecular spectroscopy of gas phase molecules excited by synchrotron radiation in the VUV and soft X-ray regions. We have used three different detection techniques, photon induced fluorescence spectroscopy, photoionisation mass spectroscopy and near edge X-ray absorption fine structure spectroscopy to study molecular deuterium, hydrogen sulphide, ammonia, methanol, pyridine, pyridazine, pyrimidine, pyrazine, s-triazine, and 2-deoxy-D-ribose, the last one also known as the DNA sugar.

  5. 3. Characterization of Self-Assembled Monolayers of Oligo(phenyleneethynylene) Derivatives on Gold

    Author : Somsakul Watcharinyanon; Lars Johannson; Ellen Moons; Stacey Sorensen; Karlstads universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Self-assembled monolayers; Oligo phenyleneethynylene ; high-resolution X-ray photoemission spectroscopy HRXPS ; near-edge X-ray absorption fine structure spectroscopy NEXAFS ; Material physics with surface physics; Materialfysik med ytfysik; Physics; Fysik;

    Abstract : Oligo(phenyleneethynylene) (OPE) molecules are a class of fully conjugated aromatic molecules, that attract attention for their application as “molecular wires” in molecular electronic devices. In this thesis work, self-assembled monolayers (SAMs) formed from a variety of OPE derivatives have been studied. READ MORE
