  1. 1. Imagining the Organic City : Modern Tropes of Organization

    University dissertation from Alnarp : Acta Universitatis Agriculturae Sueciae

    Author : Meike Schalk; Kenneth Olwig; Sven Olov Wallenstein; Helena Mattsson; M Christine Boyer; [2007]
    Keywords : HUMANIORA; HUMANITIES; organic; organism; types; evolution; city; society; biology; Patrick Geddes; urban design; metabolism; organization;

    Abstract : The thesisexamines three ’organic tropes’ of modern architecture and urban design, addressing different crucial moments of change within modernist discourse. Attention is focused on the institutionalization of ‘town planning’ at the turn of the last century; the shift during the post-war years; and the beginning of urban debate in Japan during the early 1960s.

  2. 2. Development and Mechanistic Studies of Molecularly Defined Water Oxidation Catalysts : Catalysts for a Green and Sustainable Future

    University dissertation from Stockholm : Department of Organic Chemistry, Stockholm University

    Author : Markus Kärkäs; Björn Åkermark; Jean-François Nierengarten; [2013]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; artificial photosynthesis; water oxidation; photochemistry; electrochemistry; Organic Chemistry; organisk kemi;

    Abstract : This thesis deals with the development of complexes that are active catalysts for H2O oxidation. Promoting proton-coupled electron transfer has been a highly important feature in the development of these catalysts. READ MORE

  3. 3. The Synthesis of Molecular Switches Based Upon Ru(II) Polypyridyl Architecture for Electronic Applications

    University dissertation from Institutionen för biologi och kemiteknik

    Author : Robert Steen; Simon Dunne; Jan Bergman; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular Electronics; ruthenium; pyridyl complexes; ligand design; ligand synthesis; NATURAL SCIENCES Chemistry Organic chemistry; NATURVETENSKAP Kemi Organisk kemi; Biotechnology Chemical Engineering; bioteknik kemiteknik;

    Abstract : According to the famous axiom known as Moore’s Law the number of transistors that can be etched on a given piece of silicon, and therefore the computing power, will double every 18 to 24 months. For the last 40 years Moore’s prediction has held true as computers have grown more and more powerful. READ MORE

  4. 4. Synthesis and investigation of bacterial effector molecules

    University dissertation from Umeå : Umeå University

    Author : Michael Franz Albers; Christian Hedberg; Christian Hackenberger; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; bacterial effectors; organic synthesis; Legionella; PTM; peptide synthesis; nucleotide chemistry; Biorganic Chemistry; bioorganisk kemi;

    Abstract : During infections, bacterial microorganisms initiate profound interactions with mammalian host cells. Usually defense mechanisms of the host destroy intruding bacteria in rapid manner. However, many bacterial pathogens have evolved in a way to avoid these mechanisms. READ MORE

  5. 5. Physicochemical and Structural Aspects of Nucleic Acids

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Subhrangsu Chatterjee; Adolf Gogoll; Helena Grennberg; Göran Widmalm; [2007]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; pKa; Hydrogen bonding; Stacking; NMR; MD; DNA; RNA; Pyrimidine; Organisk kemi;

    Abstract : This thesis consists of seven research publications concerning (i) pKa studies of nucleobases in model nucleotides to understand why RNA duplexes are more stable than DNA duplexes (Paper I), (ii) the role of Me(T)-π interactions in the relative stability of DNA-RNA heteroduplexes (Paper II), (iii) pKa measurements in nucleotides with different 2′-substituents (paper III), (iv) a conformation study of constrained sugars and a pKa study of 1-thyminyl to reveal effect of sugar constraints on the pKa of the nucleobase (paper IV), (v) NMR and MD studies of 1′, 2′-oxetane constrained thymidine incorporated Dickerson Drew dodecamer (paper V), (vi) the sequence dependent pKa perturbation of 9-guaninyl moeity in single stranded (ss) DNA and RNA (paper VI), (vii) the non identical chemical nature of internucleotidic phosphates in (ss) RNA using 31P NMR (paper VI), and an alkaline hydrolysis study of phosphodiesters in ssRNAs (paper VII). The architecture of DNA and RNA molecules is determined by (a) hydrogen bonding (b) base stacking (c) a variety of additional non-covalent interactions. READ MORE
