  1. 1. Microgels as drug carriers : Relationship between release kinetics and self-aggregation of the amphiphilic drugs adiphenine, pavatrine and diphenhydramine.

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för läkemedelskemi

    Författare :Lobna Ali Mohsen; [2021]
    Nyckelord :Amphiphilic drugs; small angle x-ray scattering; macrogels; binding isotherm; CMC; self-aggregation; phase structure; micelles.;

    Sammanfattning : Abstract There has been great interest in microgels as drug carriers within the pharmaceutical industry. This includes the use of amphiphilic drugs for treating conditions such as depression, allergies, and cancer. LÄS MER

  3. 2. Sn-Pb-mixtures for Perovskite Solar Cells

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Fanny Amanda Karolina Baumann; [2020]
    Nyckelord :Perovskite Solar Cells; PSC; Sn; Tin; Lead; Pb; FAPI; Renewable Energy; Compositional Engineering; Interfaces; Morphology; PL; Photoluminescence; Thin film stability; Technology and Engineering;

    Sammanfattning : Perovskite research has quickly gone from non-existent to one of the biggest reseach areas in Photo- voltaics. There are still many questions to be solved regarding the stability, environmental impact, reproducible large area devices, efficiency and module fabrication cost of Perovskite Solar Cells, PSCs, before commercial up-scaling.

  4. 3. Bioactivity testing of dental materials

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Alexander Eriksson; [2019]
    Nyckelord :Bioactivity; bioactive glass; soaking experiment;

    Sammanfattning :  Ever since Hench et al. first discovered bioactive glass in 1969, extensive interest was created because of the materials ability to chemically bond with living tissue. In this project the bioactivity of three different compositions of the bioactive glass Na2O-CaO-SiO2 have been studied. LÄS MER

  5. 4. NINA - A DIGNIFIED MAMMOGRAPHY EXPERIENCE : Rethinking breast cancer diagnostics

    Master-uppsats, Umeå universitet/Designhögskolan vid Umeå universitet

    Författare :Karl-Otto Saarman; [2017]
    Nyckelord :industrial design; breast cancer; mammography; user centred;

    Sammanfattning : What are things occurring in peoples mind when thinking about ‘mammography’? Some might not be entirely sure about what mammography is, some might get a feeling of discomfort and some may be very familiar with this method of finding breast cancer tumors. But why is it that many women get ner-vous when thinking about mammography and common words used when describing it are: discomfort, loneliness, pain and “ouch”?  This thesis project started by exploring methods for diagnosing and treating breast cancer.

  7. 5. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

    Master-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

    Författare :Jonatan Fast; [2017]
    Nyckelord :Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

    Sammanfattning : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.
