  1. 21. SnOx electron selective layers for perovskite/silicon tandem solar cells using atomic layer deposition

    Master-uppsats, KTH/Energiteknik

    Författare :Lisa Anna Zafoschnig; [2018]
    Nyckelord :;

    Sammanfattning : In this work the application of ALD deposited SnOx films as electron transport layers in perovskite solar cells is analysed. Processes to fabricate homogeneous, transparent and conductive tin oxide films were developed on an Oxford Instruments FlexAL tool using a TDMASn precursor and H2O as oxidiser. LÄS MER

  3. 22. Lake Victoria - Carbon, Nitrogen, Phosphorus and Stable Isotope (δ13C) comparison between lake and catchment sediments

    Master-uppsats, Linköpings universitet/Tema Miljöförändring

    Författare :Laxmi Gayatri Devi Basapuram; [2018]
    Nyckelord :Nutrients; Stable isotope δ13C ; Agriculture; Industrialization; Eutrophication;

    Sammanfattning : Lake Victoria situated in East Africa faces an acute problem with eutrophication. Many reasons like agricultural production, industrialization, anthropogenic processes, the introduction of species, and economic activities have caused a stress to the overall well-being of the lake.

  4. 23. A canonical correlation analysis- based approach to identify causal genes in atherosclerosis

    Magister-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Crisencia Sizyoogno; [2018]
    Nyckelord :Canonical correlation analysis; Atherosclerosis; bioinformatics; CRISPR_Cas9; Phenotypes; Genotypes; GWAS; zebrafish; Cardiovascular and metabolic disease;

    Sammanfattning : Genome-wide associations studies (GWASs) have identified hundreds of loci that are strongly associated with coronary artery disease and its risk factors. However, the causal variants and genes remain unknown for the vast majority of the identified loci. LÄS MER

  5. 24. Trophic transfer of per- and polyfluoroalkyl substances (PFASs) by glacial relicts in Lake Vättern, Sweden

    Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknik

    Författare :Malin Bergman; [2017]
    Nyckelord :;

    Sammanfattning : The aim with the study was to assess if glacial relict amphipods constitute as vectors of transport of per- and polyfluoroalkyl substances (PFASs) in the Arctic char food web in Lake Vättern, Sweden. Sediment, surface water and biota samples were analysed for PFASs using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and stable isotope analysis of δ 13C and δ15N was performed on sediments and biota samples.

  7. 25. Surface energy modification of metal oxide to enhance electron injection in light-emitting devices : charge balance in hybrid OLEDs and OLETs

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Sergio Apicella Fernandez; [2017]
    Nyckelord :organic; inorganic; semiconductors; OLEDs; OLETs; TFT; stack; thin-film; deposition; spin-coating; thermal; evaporation; process; reactive; sputtering; luminescence; EQE; PEIE; metal-oxide; ZnO; ZnO:N; MoO3; F8BT; Alq3; NPB;

    Sammanfattning : Organic semiconductors (OSCs) present an electron mobility lower by several orders of magnitude than the hole mobility, giving rise to an electron-hole charge imbalance in organic devices such as organic light-emitting diodes (OLEDs) and organic light-emitting transistors (OLETs). In this thesis project, I tried to achieve an efficient electron transport and injection properties in opto-electronic devices, using inorganic n-type metal oxides (MOs) instead of organic n-type materials and a polyethyleneimine ethoxylated (PEIE) thin layer as electron transport (ETLs) and injection layers (EILs), respectively.
