  1. 1. Nanostructure and biomolecule interactions : Characterizing the complex

    Author : Stefan Gunnarsson; NanoLund; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Nanostructures; Proteins; Lipids; Protein corona; Aggregation; Sedimentation; Diffusion; Electron microscopy; Enzyme activity; Nanowires; Nanoparticles;

    Abstract : This thesis presents the results of studies done on various biomolecules and their interactions with nanomaterials. The biomolecule sources are everything from purified, single proteins to the complicated mixture of blood serum and cell culture media. READ MORE

  2. 2. Skin cancer prevention : Readiness to change sun-related behaviours

    Author : Sveinbjörn Kristjánsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Skin cancer; prevention; sun protection; sunscreen; sun exposure; stages of change; Transtheoretical Model; behavioural change.;

    Abstract : The general aim of this thesis was to collect data relevant for skin cancer prevention and to investigate the applicability of the Transtheoretical Model for sun-related behaviour. Also, to assess the readiness to change five different sun-related behaviours in the general population in Stockholm County. READ MORE

  3. 3. Studies of Sunscreens: Percutaneous Absorption of Benzophenone-3 and Photostability

    Author : Helena Gonzalez; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : benzophenone-3; dihydroxy benzophenone; sunscreens; UV radiation; reverse-phase HPLC; photostability;

    Abstract : Studies of Sunscreens: Percutaneous Absorption of Benzophenone-3 and Photostability Helena Gonzalez Department of Dermatology and Venereology Institute of Clinical Sciences The Sahlgrenska Academy at Göteborg University Göteborg, Sweden Abstract Aim: To learn more about percutaneous absorption of the photoactive compound benzophenone-3 (BZ-3) and to study the excretion pattern of BZ-3 and its metabolite dihydroxy benzophenone (DHB). We also got the opportunity to develop a reverse-phase HPLC method to analyze BZ-3 and DHB. READ MORE

  4. 4. Assessment of UV exposure in a young metropolitan population

    Author : Cecilia Boldeman; Karolinska Institutet; Karolinska Institutet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; Adolescents; Behaviors; Erythema; Phenotype; Skin cancer; Sunbed use;

    Abstract : Overexposure to UVR causes >80% of skin cancers, and >30% of all diagnosed cancers in western societies, Sweden included, are skin cancers. Overexposure in terms of UV-induced erythema during childhood and adolescence is considered particularly harmful. READ MORE

  5. 5. Dynamics of Photoinduced Processes in Dye-Sensitized Nanocrystalline Semiconductor Films--Reactions in the Photoactive Part of the Grätzel Solar Cell

    Author : Gabor Benko; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supraledare; magnetisk resonans; spektroskopi; magnetiska och optiska ; egenskaper elektriska; Kondenserade materiens egenskaper:elektronstruktur; spectroscopy; relaxation; magnetic resonance; supraconductors; Kemi; Condensed matter:electronic structure; electrical; femtosecond spectroscopy; solar cells; Chemistry; excited states; photoinduced electron transfer; transition metal complexes; nanocrystalline titanium dioxide; dye sensitization; porous semiconductor film; magnetic and optical properties;

    Abstract : The key materials used to convert solar energy into electricity in the Grätzel-type solar cells are dye molecules and titanium dioxide particles attached to each other. The former are similar to those in common products like purple pigments in blueberry juice, while the latter are like sunscreen, white paint, or toothpaste. READ MORE
