  2. 1. New Fullerene Materials Obtained in Solution and by High Pressure High Temperature Treatment

    Author : Alexandr Talyzin; B. Sundqvist; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; fullerene; solution; high pressure; Raman spectroscopy; polymerisation; XRD; Kemi; Chemistry; Kemi; Inorganic Chemistry; oorganisk kemi;

    Abstract : Crystallization of C60 and C70 from organic solution often leads to the formation of new solvates and other fullerene compounds. In the present thesis, a number of such solvates were obtained and their phase transitions studied using in situ "in solution" techniques. READ MORE

  4. 2. Implementation of MRI gel dosimetry in radiation therapy

    Author : Sven Bäck; Malmö Medicinsk strålningsfysik; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; oncology; Cytology; uncertainty; detector; dosimeter; ferrous ions; gel dosimetry; magnetic resonance imaging; monomers; polymerisation; proton; treatment planning verification; radiation therapy; cancerology; Cytologi; onkologi; cancer;

    Abstract : Gel dosimetry was used together with magnetic resonance imaging (MRI) to measure three-dimensional absorbed dose distributions in radiation therapy. Two different dosimeters were studied: ferrous- and monomer gel, based on the principles of radiation-induced oxidation and polymerisation, respectively. READ MORE

  5. 3. Epoxides as Contact Allergens - Formation, Sensitising Potency and Structure-Activity Relationships

    Author : Ida Belogorcev Niklasson; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Allergic contact dermatitis; Autoxidation; Bioactivation; Cinnamic alcohol; Diglycidyl ether of bisphenol A DGEBA ; Epoxide; Epoxy resin; Local lymph node assay; Polymerisation; Peptide reactivity; Prehapten; Prohapten; Sensitisation; Skin; Structure-Activity Relationship; Thermogravimetric Analysis;

    Abstract : Chemicals in our environment with which we have repeated skin contact can cause skin sensitisation (contact allergy). To trigger an immune response a compound (hapten) must be able to penetrate the skin, where it needs to be reactive enough to bind to proteins and form immunogenic complexes that are recognised as foreign.

  6. 4. Towards the Rational Design of Molecularly Imprinted Polymers

    Author : Håkan S Andersson; Ann-Christin Koch-Schmidt; Ian A Nicholls; Klaus Mosbach; Richard F Venn; Tillämpad biokemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Thermodynamics; Molecular Recognition; Polyvalency; Cooperativity; Electrostatic Interactions; Hydrophobic Effect; Chromatography; Frontal Analysis; HPLC; Spectroscopy; Molecularly Imprinted Polymer; Molecular Imprinting; Crown Ether; Template Polymerisation; Cyclodextrin; Biochemistry; Metabolism; Biokemi; Biotechnology; Bioteknik; molecular recognition; Biokemi;

    Abstract : Molecular imprinting is a technique by which polymeric materials selective for a given target molecule can be created through a casting procedure. Functionalised monomers are added to a solution of molecular templates. READ MORE

  7. 5. Responsive Molecular Systems through Dynamic Covalent Chemistry

    Author : Antanas Karalius; Zoltan Szabo; Stefan Matile; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stimuli-responsiveness; dynamic covalent reactions; systems chemistry; constitutional dynamics; non-equilibrium systems; nitroaldol reaction; dynamers; reversible polymerization; boronate ester; imine ligand; metal coordination; self–assembly; emergent properties; network topology.; stimuli-responsivitet; dynamiska kovalenta reaktioner; systemkemi; konstitutionell dynamik; icke-jämviktssystem; nitroaldolreaktion; dynamerer; reversibel polymerisation; boronester; iminligand; metallkoordination; själv-organisation; emergenta egenskaper; nätverkstopologi.; Kemi; Chemistry;

    Abstract : Nature tends to inspire research in chemistry. Systems that emerge from molecules interacting via reaction networks is something that life has mastered over the course of evolution in order to produce complexity. Dynamic reactions are key in systems chemistry, where reaction networks give rise to complex, emergent behavior. READ MORE
