  1. 1. Packing effects in palladium(II) and platinum(II) compounds, X-ray crystallography

    Författare :Maria Johansson; Kemiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Inorganic chemistry; Platinum II ; Palladium II ; Half-normal probability plots; X-ray crystallography; Packing effects; Oorganisk kemi;

    Sammanfattning : This thesis focuses on i) the effect of packing on the molecular geometry ii) packing arrangements of neutral Pd(II) and Pt(II) complexes iii) the trans influence in Pt(II) complexes iv) the differences in bonding in corresponding Pd(II) and Pt(II) complexes and v) the geometry of Pd(II) complexes with potential catalytic properties. Detailed three-dimensional structural information at the atomic level can be obtained from X-ray crystallography. LÄS MER

  3. 2. Double Layer Forces: the Role of Molecular Solvents

    Författare :Luis Pegado; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dielectric continuum model; molecular solvent; Stockmayer fluid; electrical double layer; ion-ion correlations; Monte Carlo simulations; thermodynamic modeling; pressure curves; interaction free energy; packing effects;

    Sammanfattning : The dielectric continuum model has rightfully been and continues to be a major workhorse for theory and modelling in Surface and Colloid Chemistry. Due to the implicit description of water, entering only as a scaling constant for charge-charge interactions, one would not expect it to work for short distances. LÄS MER

  4. 3. Making packaging more sustainable: Effects of resource embeddedness

    Författare :Sandra Brüel Grönberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; packaging; e-commerce; embeddedness; sustainability; business network; resource; distribution; network setting;

    Sammanfattning : Firms involved in e-commerce distribution are faced with challenges due to the increasing volume of single shipments to consumers, including concerns regarding sustainability. For instance, the role of packaging has gained increased attention because of over-packed parcels and excessive air within those parcels, which frustrate retailers, logistics service providers, and consumers.

  5. 4. The influence of particle shape of coating pigments on their packing ability and on the flow properties of coating colours

    Författare :Sven Lohmander; KTH; []
    Nyckelord :aspect ratio; capillary viscometry; coating colour; filtration. Particle packing;

    Sammanfattning : The influence of particle shape of coating pigments on theirpacking ability and on the flow properties of coating colourshas been investigated. The particle shapes considered werespherical, flaky and acicular (needle-shaped). LÄS MER

  7. 5. Amphiphilic Peptide Interactions with Complex Biological Membranes : Effect of peptide properties on antimicrobial and anti-inflammatory effects

    Författare :Shalini Singh; Martin Malmsten; Per Hansson; Debora Berti; Uppsala universitet; []
    Nyckelord :LPS; Antimicrobial; Peptide; Inflammation; Infections; Liposome; Binding; PEG; Farmaceutisk fysikalisk kemi; Pharmaceutical Physical Chemistry;

    Sammanfattning : With increasing problem of resistance development in bacteria against conventional antibiotics, as well as problems associated with diseases either triggered or enhanced by infection, there is an urgent need to identify new types of effective therapeutics for the treatment of infectious diseases and its consequences. Antimicrobial and anti-inflammatory peptides have attracted considerable interest as potential new antibiotics in this context. LÄS MER
