  2. 1. Local Structure of Hydrogen-Bonded Liquids

    Author : Matteo Cavalleri; Lars G.M. Pettersson; John Tse; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrogen-bond; water; ice; density functional theory; DFT; core-level spectroscopies; x-ray absorption; Physical chemistry; Fysikalisk kemi;

    Abstract : Ordinary yet unique, water is the substance on which life is based. Water seems, at first sight, to be a very simple molecule, consisting of two hydrogen atoms attached to one oxygen. READ MORE

  4. 2. Structure Modeling with X-ray Absorption and Reverse Monte Carlo: Applications to Water

    Author : Mikael Leetmaa; Lars G M Pettersson; John Rehr; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; water structure; x-ray absorption; spectroscopy; diffraction; reverse monte carlo; XAS; EXAFS; XANES; RMC; TP-DFT spectrum calculations; Physics; Fysik; kemisk fysik; Chemical Physics;

    Abstract : Water is an important substance. It is part of us, of our environment, and is a fundamental prerequisite for the existence of life as we know it. The structure of water is still, after over 100 years of research on the subject, however under debate. READ MORE

  5. 3. Le Fantôme de l’Opéra - Studies on Atoms and Electrons Beneath

    Author : Chang Liu; Lars G. M. Pettersson; Anders Nilsson; Anders Hellman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Carbon dioxide reduction; Subsurface oxygen; X-ray spectroscopy; Density functional theory; CO desorption; teoretisk fysik; Theoretical Physics;

    Abstract : The carbon dioxide reduction reaction is a promising candidate to tackle ecological challenges of our age. This is due to its capability of reducing carbon dioxide emission generated from the combustion of fossil fuels by converting carbon dioxide into valuable hydrocarbons. READ MORE

  6. 4. Molecular structure and dynamics of liquid water : Simulations complementing experiments

    Author : Daniel Schlesinger; Lars G. M. Pettersson; Paola Gallo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; liquid water; supercooled water; molecular simulation; evaporative cooling; teoretisk fysik; Theoretical Physics;

    Abstract : Water is abundant on earth and in the atmosphere and the most crucial liquid for life as we know it. It has been subject to rather intense research since more than a century and still holds secrets about its molecular structure and dynamics, particularly in the supercooled state, i. e. the metastable liquid below its melting point.

  7. 5. X-ray scattering and spectroscopy of supercooled water and ice

    Author : Jonas A. Sellberg; Anders Nilsson; Lars G. M. Pettersson; Thomas Loerting; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; supercooled water; ice; x-ray scattering; x-ray spectroscopy; free-electron laser; kemisk fysik; Chemical Physics;

    Abstract : This thesis presents experimental studies of water and ice at near-atmospheric pressures using intense x-rays only accessible at synchrotrons and free-electron lasers. In particular, it focuses on the deeply supercooled, metastable state and its implications on ice nucleation. READ MORE
