    Abstract : Due to climate change and plastic pollution, there is an increasing demand for bio-based materials with similar properties to those of common plastics yet biodegradable. In this respect, cellulose is a strong candidate that is already being refined on a large industrial scale, but the properties differ significantly from those of common plastics in terms of shapeability and water-resilience.

  2. 2. Light-Triggered Conformational Switches for Modulation of Molecular Recognition Applications for Peptidomimetics and Supramolecular Systems

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Magnus Blom; Uppsala universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bisporphyrin tweezers; peptidomimetics; host-guest systems; conformational analysis; supramolecular chemistry; photochemistry; Organisk kemi; Organic Chemistry; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Abstract : The main focus of this thesis is on photochemical modulation of molecular recognition in various host-guest systems. This involves the design, synthesis and integration of light-triggered conformational switches into peptidomimetic guests and molecular tweezer hosts. READ MORE

  3. 3. Application of the 2-Pyridone Hydrogen-Bonding Motif in Supramolecular Catalysis and in Phenanthroline Based Ligands

    University dissertation from Organic Chemistry, Lund University

    Abstract : Popular Abstract in Swedish Det största bidraget till komplexitet i kemiska system kommer inte från de kemiska komponenternas molekulära struktur, utan deras växelverkan med varandra. Vi har mycket större kännedom om molekylär struktur i biologiska celler och organismer än om detaljerna i deras växelverkan. READ MORE

  4. 4. Efficient Carbohydrate Synthesis By Intra- and Supramolecular Control

    University dissertation from Stockholm : KTH
