  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. Characterising Weak Interactions in Solution. : An NMR Spectroscopic Approach

    Author : Scott Wilcox; Máté Erdélyi; Chris Hunter; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kemi med inriktning mot organisk kemi; Chemistry with specialization in Organic Chemistry;

    Abstract : Detecting and characterising weak interactions in dilute solutions is challenging. This thesis focusses on the development of a new NMR spectroscopic strategy to do so, whilst also investigates a newly proposed type of weak interaction in solution with currently available NMR techniques.

  5. 3. Unsaturated Fatty Acids in Alkane Solution : Adsorption and Tribological Properties

    Author : Sarah M. Lundgren; Per M. Claesson; Hugh Spikes; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry; Kemi;

    Abstract : Fatty acids and blends of fatty acids are used as friction modifiers and anti-wear additives in diesel fuels. A large part of some fatty acid blends are unsaturated fatty acids. Even though fatty acids have been thoroughly investigated, the adsorption and tribological behaviour of unsaturated fatty acids are no fully understood. READ MORE

  6. 4. Surface modification of inorganic materials with graphene oxide : From solution to high-temperature synthesis

    Author : Simon Tidén; Ulf Jansson; Mamoun Taher; Erik Lewin; Lars Nyborg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Graphene; Graphene oxide; Coatings; Additive Manufacturing; Laser Powder Bed Fusion; Reactive Hot Pressing; Kemi med inriktning mot materialkemi; Chemistry with specialization in Materials Chemistry;

    Abstract : The use of graphene as an additive in materials is often challenging due to the agglomeration of the two-dimensional graphene sheets. An alternative additive is graphene oxide (GO), an oxidized form of graphene, which is easily dispersed in water. READ MORE

  7. 5. Numerical Solution Methods in Stochastic Chemical Kinetics

    Author : Stefan Engblom; Per Lötstedt; Wilhelm Huisinga; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; stochastic models; chemical master equation; mesoscopic kinetics; Markov property; jump process; moment closure problem; spectral-Galerkin method; high dimensional problem; hybrid methods; time-parallel; homogenization; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : This study is concerned with the numerical solution of certain stochastic models of chemical reactions. Such descriptions have been shown to be useful tools when studying biochemical processes inside living cells where classical deterministic rate equations fail to reproduce actual behavior. READ MORE
