  1. 1. NMR Studies of Bacterial Albumin-Binding Modules

    University dissertation from Eva Hagen/Bodil Forsvik, Biophysical Chemistry, Lund University

    Author : Maria U Johansson; Lund University.; Lunds universitet.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Biotechnology; Bioteknik; Proteins; enzymology; Proteiner; enzymologi; Physical chemistry; three-helix bundle; protein structure; protein PAB; protein-protein interactions; protein G; protein dynamics; NMR; module shuffling; GA module; evolution; albumin-binding; bacterial surface proteins;

    Abstract : Peptostreptococcus magnus and group C/G streptococci are Gram-positive cocci that are part of the normal flora and reside in more or less the same locations in the host. Protein G of group C/G streptococci was originally described as binding IgGFc of several species and later shown to also bind human serum albumin and albumins from various animal species. READ MORE

  2. 2. Evasion and Attack: Structural Studies of a Bacterial Albumin-binding Protein and of a Cephalosporin Biosynthetic Enzyme

    University dissertation from Uppsala : Universitetsbiblioteket

    Author : Sara Lejon; Uppsala universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; human serum albumin; GA module; albumin-binding; Finegoldia magna; deacetylcephalosporin C acetyltransferase; cephalosporin C; antibiotic; beta-lactam; biosynthesis; Acremonium chrysogenum; X-ray crystallography; NATURAL SCIENCES Chemistry Biochemistry Structural biology; NATURVETENSKAP Kemi Biokemi Strukturbiologi;

    Abstract : This thesis describes the crystal structures of two proteins in the context of combatting bacterial infections. The GA module is a bacterial albumin-binding domain from a surface protein expressed by pathogenic strains of the human commensal bacterium Finegoldia magna. READ MORE

  3. 3. Design and Stability of Cu(In,Ga)Se2-Based Solar Cell Modules

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Johan Wennerberg; Uppsala universitet.; [2002]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Thin film solar cells; CIGS; Cu In; Ga Se2; stability; lifetime; testing; Elektronik; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektronik; Elektronik; Electronics;

    Abstract : Cu(In,Ga)Se2 (CIGS) is one of the most promising semiconductor compounds for large-scale production of efficient, low-cost thin film solar cells, and several research institutes have announced their plans for CIGS production lines. But for the CIGS technology to become a commercial success, a number of issues concerning manufacturability, product definition, and long-term stability require further attention. READ MORE

  4. 4. ALD Buffer Layer Growth and Interface Formation on Cu(In,Ga)Se2 Solar Cell Absorbers

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Jan Sterner; Uppsala universitet.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; thin film; Cu In; Ga Se2; CIGS; chalcopyrite; ALD; sulfurization; buffer layer; XPS; UPS; electron spectroscopy; band alignment; atomic layer deposition; Elektronik; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektronik;

    Abstract : Cu(In,Ga)Se2 (CIGS) thin film solar cells contain a thin layer of CdS. To avoid toxic heavy-metal-containing waste in the module production the development of a cadmium-free buffer layer is desirable. This thesis considers alternative Cd-free buffer materials deposited by Atomic Layer Deposition (ALD). READ MORE

  5. 5. ZrN Back-Contact Reflectors and Ga Gradients in Cu(In,Ga)Se2 Solar Cells

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Abstract : Solar cells constitute the most direct way of converting solar energy to electricity, and thin-film solar-cell technologies have lately been growing in importance, allowing the fabrication of less expensive modules that nonetheless have good power-conversion efficiencies. This thesis focuses on solar cells based on Cu(In,Ga)Se2, which is the thin-film technology that has shown the highest conversion efficiency to date, reaching 20. READ MORE
