  1. 26. High Bandgap FAPbBr3 Perovskite Solar Cells : Preparation, Characterization, and Application

    Författare :Yawen Liu; Erik Johansson; Tönu Pullerits; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; High-bandgap FAPbBr3; additives; defect passivation; dopant-free HTMs; 2D perovskites; carbon electrode; oxygen evolution; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Sammanfattning : High bandgap lead-halide perovskite solar cells (PSCs) have gained interest as top cells for tandem solar cells and photoelectrochemical applications due to their suitable energy bands. However, the PSCs have limited stability and performance, and their fabrication in a glovebox and utilization of expensive metal contacts increase the cost and limit their application. LÄS MER

  3. 27. Characterization of chromosome abnormalities

    Författare :Anna Lindstrand; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Inborn chromosome abnormalities are a frequent cause of mental retardation and birth defects. Apart from aberrations that are visible in the microscope, a number of submicroscopic alterations have recently been discovered, and all of these chromosome changes are in fact the result of DNA alterations at the molecular level.

  4. 28. Characterization of Starch Using Flow Field-Flow Fractionation Techniques

    Författare :Catalina Fuentes; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : To improve the properties and functionality of starch, it is important to understand the physicochemical and structural characteristics as raw material, after being modified to increase its characteristics and/or during changes due to the processing conditions. For this reason, the objective of the present thesis is to improve the understanding of characteristics and molecular properties like molar mass (M), root-mean-square radius (rrms) and their relation to other physicochemical properties of starch extracted from different sources.

  5. 29. Bioinformatic methods in protein characterization

    Författare :Yvonne Kallberg; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Bioinformatic methods in protein characterization;

    Sammanfattning : Bioinformatics is an emerging interdisciplinary research field in which mathematics. computer science and biology meet. In this thesis. bioinformatic methods for analysis of functional and structural properties among proteins will be presented. LÄS MER

  7. 30. Applied bioinformatics for gene characterization

    Författare :Raf M Podowski; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :bioinformatics; gene characterization; text mining; data visualization;

    Sammanfattning : As the vast majority of human protein-encoding genes are now identified, the new challenge placed before life scientists is the determination of the functions of the proteins. Traditionally, intense, directed efforts are applied to decipher the function of a novel protein using laboratory techniques. LÄS MER
