  1. 1. Phase Transformations in Solid Pharmaceutical Materials Studied by AFM, ESCA, DSC and SAXS

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Denny Mahlin; Uppsala universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; polymer; lipid; lactose; phase transformation; phase formation; crystallisation; AFM; X-ray diffraction; ESCA; DSC; solid dispersion; Fysikalisk kemi; NATURAL SCIENCES Chemistry Physical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi;

    Abstract : Mixing excipients is a common way to produce pharmaceutical materials with suitable properties for drug formulation. An understanding of the basic mechanisms involved in the formation and transformation of the structures of solid state mixtures is crucial if one is to be able to produce materials with the desired properties in a reliable way.

  2. 2. Macromolecules at Interfaces

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Helén Larsericsdotter; Uppsala universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Protein; Adsorption; Immobilization; Surface; Surface Plasmon Resonance; SPR; Mass Spectrometry; MS; Differential Scanning Calorimetry; DSC; FT ICR; Lysozyme; Bovine Serum Albumin; BSA; Myoglobin; Globular; Kemi; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : In this thesis, the structure and stability of globular proteins adsorbed onto nanometer-sized hydrophilic silica particles were investigated using differential scanning calorimetry (DSC), hydrogen/deuterium exchange (HDX), and mass spectrometry (MS). The adsorption process itself was characterized with fluorescence and absorption spectroscopy and surface plasmon resonance (SPR). READ MORE

Theincreased cooling demand results in a peak in electrical powerdemand during the hottest summer hours. READ MORE

  5. 5. Biological membrane interfaces involved in diseases a biophysical study

    University dissertation from Umeå : Kemi

    Author : Fredrick Lindström; Umeå universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Solid-state NMR; DSC; Amyloid-beta peptide; Nociceptin; DMPC; DMPG; DDAB; peptide-lipid interaction; branched-chain fatty acid.; NATURAL SCIENCES Chemistry Physical chemistry Biophysical chemistry; NATURVETENSKAP Kemi Fysikalisk kemi Biofysikalisk kemi;

    Abstract : Interactions between peptides and biological lipid membranes play a crucial role in many cellular processes such as in the mechanism behind Alzheimer’s disease where amyloid-beta peptide (Abeta)is thought to be a key component. The initial step of binding between a surface active peptide and its target membrane or membrane receptor can involve a non specific electrostatic association where positively charged amino acid residues and a negatively charged membrane surface interact.
