  1. 1. Molecular Electronics : Insight from Ab-Initio Transport Simulations

    Författare :Jariyanee Prasongkit; Rajeev Ahuja; Magnus Paulsson; Uppsala universitet; []
    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

  2. 2. Molecular Electronics : A Theoretical Study of Electronic Structure of Bulk and Interfaces

    Författare :Mikael Unge; Sven Stafström; Mads Brandbyge; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecular electronics; electron transport; disorder; localization; long-range correlation; organometallic magnets; interface dipole; Computational physics; Beräkningsfysik;

    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

  3. 3. Molecular filtration : the study of adsorbents

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

  4. 4. Molecular Regulation of Inflammation and Angiogenesis in the Tumor Microenvironment

    Författare :Lothar Dieterich; Anna Dimberg; Lena Claesson-Welsh; Jonas Fuxe; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; stroma; glioma; alphaB-crystallin; HSPB5; cryab; myeloid cells; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi; Cell and molecular biology; Cell- och molekylärbiologi; Molekylär medicin; Molecular Medicine;

    Sammanfattning : Tumor growth and progression not only depend on properties of the malignant cells but are strongly influenced by the tumor microenvironment. The tumor stroma consists of various cell types such as inflammatory cells, endothelial cells and fibroblasts, which can either inhibit or promote tumor growth. LÄS MER

  5. 5. Modulation of Molecular Properties : Host–Guest Interactions for Structural Analysis and Chemical Reactions

    Författare :Sara Norrehed; Adolf Gogoll; Jerker Mårtensson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; host-guest systems; conformational analysis; NMR spectroscopy; bispidines; porphyrins; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Sammanfattning : This thesis concerns the construction, use and modulation of various host–guest systems, from small bispidines for binding of inorganic ions to bisporphyrin clips for supramolecular systems.Small flexible molecules undergo fast conformational movements when in solution. LÄS MER
