  1. 1. Design, Synthesis and Properties of Bipyridine-capped Oligothiophenes for Directed Energy and Electron Transfer in Molecular Electronic Applications

    Author : Lasse Nurkkala; Simon Dunne; Sarah Angus-Dunne; Edwin Constable; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Molecular Electronics; Organic Synthesis; Ruthenium; Pyridyl Complexes; Ligand Design; Chemical engineering; Kemiteknik; Biotechnology Chemical Engineering; bioteknik kemiteknik;

    Abstract : The earliest landmark in computer technology was construction of the Electronic Numerial Integrator and Computer, ENIAC. Computational switching was performed with vacuum tubes and relays, rather large in size, making this computer rather unwieldy. READ MORE

  2. 2. UDP-sugar metabolizing pyrophosphorylases in plants : formation of precursors for essential glycosylation-reactions

    Author : Daniel Decker; Leszek A. Kleczkowski; Henrik Vibe Schelle; Umeå universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical library screening; Cell wall synthesis; Glycosylation; Nucleotide sugars; Oligomerization; Protein structure; Reverse chemical genetics; Sugar activation; UDP-sugar synthesis; biokemisk farmakologi; biochemical pharmacology; biokemi; Biochemistry; biology; biologi; molekylärbiologi; Molecular Biology;

    Abstract : UDP-sugar metabolizing pyrophosphorylases provide the primary mechanism for de novo synthesis of UDP-sugars, which can then be used for myriads of glycosyltranferase reactions, producing cell wall carbohydrates, sucrose, glycoproteins and glycolipids, as well as many other glycosylated compounds. The pyrophosphorylases can be divided into three families: UDP-Glc pyrophosphorylase (UGPase), UDP-sugar pyrophosphorylase (USPase) and UDP-N-acety lglucosamine pyrophosphorylase (UAGPase), which can be discriminated both by differences in accepted substrate range and amino acid sequences.

  3. 3. Nutrient imbalance in Norway spruce

    Author : Gunnar Thelin; Avdelningen för kemiteknik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Silviculture; Växtekologi; Plant ecology; nitrogen saturation; base saturation; pH; multiple limitation; deficiency; copper; boron; potassium; pollution; sustainability; conifers; forestry; forestry technology; Skogsvetenskap; skogsbruk; skogsteknik; Soil Science; agricultural hydrology; Lantbrukshydrologi; marklära;

    Abstract : The studies presented in my thesis indicate that growing Norway spruce in monoculture does not constitute sustainable forest management in a high N and S deposition environment, such as in southern Sweden. The combination of N-induced high growth rates and leaching due to soil acidification causes soil reserves of nutrients to decrease. READ MORE

  4. 4. Towards bacterial valorization of low molecular weight lignin

    Author : Krithika Ravi; Avdelningen för kemiteknik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Pseudomonas putida; Microbacterium sp.; Guaiacol; Syringate; Kraft lignin; Bioconversion; Biorefineries;

    Abstract : Lignin is one of the major constituents in lignocellulosic biomass and is the mostabundant source of renewable aromatics on terrestrial ecosystems. The workcarried out in this thesis concerns bacterial conversion of low molecular weightlignin. READ MORE

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

    Author : Robert Steen; Simon Dunne; Jan Bergman; Mälardalens högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular Electronics; ruthenium; pyridyl complexes; ligand design; ligand synthesis; Organic chemistry; 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
