  1. 1. Alkylglucosides - physical chemical properties

    Författare :Frederik Nilsson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; penetration experiment; DSC; SAXS; NMR self-diffusion; phase separation; size micro-structure; aggregate-aggregate interaction; liquid crystalline phases; micelles; alkylglucosides; phase diagrams; fluorescence.; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : The aim of this study is to characterise the physical-chemical properties of alkylglucosides. Alkylglucosides are non-ionic surfactants synthesized from glucose and a fatty alcohol. The glucose molecule constitutes the hydrophilic head group and the fatty alcohol constitutes the hydrophobic tail. LÄS MER

  4. 3. Complex correlations between microstructure and magnetic behavior in hard nanomagnets : A study of the structural and magnetic properties of SrFe12O19 nanocrystallites

    Författare :Pierfrancesco Maltoni; Roland Mathieu; Martin Sahlberg; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; hexaferrites; nanoparticles hard-magnetic materials; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik;

    Sammanfattning : Magnetic materials at the nanoscale are of huge scientific and technological interest, as theirmagnetic properties display remarkably different behavior compared to bulk-size. Among na-nostructured materials, M-type hexaferrite SrFe12O19 (SFO) nanoparticles (NPs) has becomeextremely appealing as promising candidate material for the renewal of permanent magnets ap-plications.

  5. 4. Alloy Plasmonics - Fundamentals and Applications

    Författare :Christopher Tiburski; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; sensing; gold-palladium; nanothermometry; palladium-hydride; nanoalloys; photothermal; plasmonics; CO oxidation; heterogeneous catalysis; dielectric function;

    Sammanfattning : Alloys have for a long time been important in the development of our society; from the Bronze Age, where man learned how to alloy copper with tin, to today, where many products are made of steel and aluminum alloys. Similarly, but maybe not as generally well known, alloys have lately been proposed as a new paradigm in nanophotonics, to tailor optical properties of nanomaterials that find applications within telecommunication, sensing, or biotechnology.

  7. 5. A theoretical study of 5-Aminolevulinic acid and its esters : properties and lipid permeability

    Författare :Edvin Erdtman; Leif Eriksson; Fahmi Himo; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biophysical chemistry; Biofysikalisk kemi; fysikalisk kemi; Physical Chemistry;

    Sammanfattning : 5-aminolevulinic acid (5ALA) is a widely used prodrug in Photodynamic therapy (PDT). The target molecule in 5ALA-PDT is Protoporphyrin IX (PpIX), which is synthesized endogenously via the heme pathway in the cell. LÄS MER
