  1. 1. Molecular Hole Punching Impulse Driven Reactions in Molecules and Molecular Clusters

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Michael Gatchell; Henning Zettergren; Henrik Cederquist; Henning Schmidt; Joachim Burgdörfer; [2016]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PAHs; Fullernes; Reactions; Clusters; Interstellar Medium; Fragmentation; Non-Statistical Fragmentation; Collisions; Experiments; Molecular Dynamics; Density Functional Theory; Physics; fysik;

    Sammanfattning : When molecules are excited by photons or energetic particles, they will cool through the emission of photons, electrons, or by fragmenting. Such processes are often thermal as they occur after the excitation energy has been redistributed across all degrees-of-freedom in the system. LÄS MER

  2. 2. Molecular Electronics Insight from Ab-Initio Transport Simulations

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Jariyanee Prasongkit; Rajeev Ahuja; Magnus Paulsson; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Molecular Electronics; Ab Initio; DNA Sequencing; Nanoscience; Graphene; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : This thesis presents the theoretical studies of electronic transport in molecular electronic devices. Such devices have been proposed and investigated as a promising new approach that complements conventional silicon-based electronics. LÄS MER

    Sammanfattning : This thesis deals with theoretical studies of the electronic structure of molecules used in the context of molecular electronics. Both studies with model Hamiltonians and first principle calculations have been performed. LÄS MER

  4. 4. Molecular Palaeopathology : Ancient DNA analyses of the bacterial diseases tuberculosis and leprosy

    Detta är en avhandling från Stockholm : Arkeologiska forskningslaboratoriet

    Författare :Emilia Nuorala; Kerstin Lidén; Ingrid Ekenman; Marie Allen; [2004]
    Nyckelord :HUMANIORA; HUMANITIES; molecular palaeopathology; ancient DNA; disease; bacteria; tuberculosis; leprosy; HUMANITIES and RELIGION History and philosophy subjects Archaeology subjects; HUMANIORA och RELIGIONSVETENSKAP Historisk-filosofiska ämnen Arkeologiämnen;

    Sammanfattning : This thesis “Molecular Palaeopathology. Ancient DNA analyses of the bacterial diseases tuberculosis and leprosy” deals with molecular palaeopathology, i.e. in this case the use of molecular methods to analyse ancient bacterial DNA in order to get further knowledge of diseases in ancient times.

  5. 5. Molecular filtration : the study of adsorbents

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ebenezer Twumasi; Christer Sjöström; Paolo Tronville; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; adsorbents; activated carbon; alumina; MgCa-silica; carbon-silica composite; characterization; porous parameters; molecular filtration; TECHNOLOGY Civil engineering and architecture Other civil engineering and architecture; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Övrig samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : Adsorbent materials for gas purification have been studied and developed for application in many areas. It is known that a single adsorbent may not adequately control multiple contaminants. Therefore, the development of adsorbent materials has accelerated over the past two decades, and is today an area attracting a lot of attention. LÄS MER
