  1. 1. Breaking the symmetry: creation and transfer of optical activity via total spontaneous resolution and stereoselective reactions

    Författare :Susanne Olsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; absolute asymmetric synthesis; enantioselective reactions; chirality; spontaneous resolution; conglomerate; organometallic chemistry; coordination compounds; attritionenhanced deracemisation; polymorphism; organolithium compounds; single-crystal X-ray crystallography;

    Sammanfattning : The generation of optical activity from achiral or racemic precursors – absolute asymmetric synthesis – is discussed in relation to the origin of biomolecular homochirality but is also often (incorrectly) regarded as being impossible. One approach to absolute asymmetric synthesis is the use of compounds that form chiral crystals. LÄS MER

  3. 2. Det svenska väldet : Ett konglomerat av uttrycksformer och begrepp från Vasa till Bernadotte

    Författare :Torbjörn Eng; Enn Tarvel; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; History; Dominion; supremacy; realm; kingdom; lordship; grand duchy; principalities; conglomerate state; unitary state; state formation; self-image; territories; Sweden; Finland; Baltic and German provinces; Scandinavia; royal titles; constitutions; coats of arms of the Swedish provinces; maps; 16th to 19th Century history; early modern times; Historia; History subjects; Historieämnen; historia; History;

    Sammanfattning : During the so-called early modern time, i.e. from 1500 to 1800, Sweden as well as other European states went through fundamental changes. The central power increased its influence and control over society and its people. LÄS MER

  4. 3. Creating Optical Activity: Total Spontaneous Resolution and Viedma Ripening

    Författare :Per Martin Björemark; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Optical activity; absolute asymmetric synthesis; total spontaneous resolution; Viedma ripening; grinding; chirality; conglomerate; coordination compound; coordination polymer; single crystal X-ray diffraction; solvent free oxidation; nantioselective sulfide oxidation; solid state VCD;

    Sammanfattning : The creation of optical activity has been considered as something impossible even though reports of such creation via total spontaneous resolution since the 1940´s have been published. More recently Viedma ripening have been developed that also produce enantiopure bulk product. Both methods are examples of absolute asymmetric synthesis i.e. LÄS MER

  5. 4. Absolute Asymmetric Synthesis

    Författare :Anders Lennartson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; absolute asymmetric synthesis; enantioselective synthesis; chirality; optical resolution; spontaneous resolution; conglomerate; organozinc reagents; organometallic chemistry; coordination chemistry; supramolecular chemistry; intermolecular interactions; optical resolution;

    Sammanfattning : Absolute asymmetric synthesis is the synthesis of optically active products from achiral or racemic precursors only. This has generally been regarded as impossible and is relevant in the discussion of the origins of biomolecular homochirality. LÄS MER

  7. 5. Chaebolföretagen - en "omöjlig" konfiguration i den sydkoreanska industrialiseringsprocessen

    Författare :Per Ingvar Jönsson; Ekonomisk-historiska institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic history; Paradigm shift; Structural breaks; Formative periods; Discontinuity; Continuity; Chaebol conglomerate; Developmental state; Ekonomisk och social historia;

    Sammanfattning : The chaebol conglomerates, which constituted the backbone of the "South Korean miracle", became the instrument for economic growth within a framework laid down by the "developmental state". With a minimum of own capital, but with private owner-control and loan-financing, these chaebols were able to expand. LÄS MER
