  1. 1. Kinetic and thermodynamic modelling of ternary nanowire growth

    Författare :Egor Leshchenko; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; III-V semiconductor materials; ternary nanowires; composition; crystal structure; modelling; Fysicumarkivet A:2021:Leshchenko;

    Sammanfattning : Among nanoscale structures of different shapes and dimensions nanowires are one of the most promising because of its truly unique properties different from their bulk counterparts. The energy quantization, perfect defect-free structure, and the possibility to grow them within the miscibility gap in combination with the benefits of bottom-up design and the possibility of integration on silicon substrates make nanowires ideal candidates for applications in optoelectronics, biotechnology and energy harvesting.

  3. 2. Catalytic partial oxidation of methane over nickel and ruthenium based catalysts for GTL applications

    Författare :Jorge A. Velasco; Magali Boutonnet; Sven Järås; Henrik Kusar; Stan Kolaczkowski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Catalytic partial oxidation; carbon formation; GTL; nickel; ruthenium; synthesis gas; thermodynamic equilibrium.; Chemical Engineering; Kemiteknik;

    Sammanfattning : The Gas to Liquids (GTL) process is an important alternative for monetizing natural gas through the production of long-chain liquid hydrocarbons, e.g. diesel fuel. LÄS MER

  4. 3. Double Layer Forces: the Role of Molecular Solvents

    Författare :Luis Pegado; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dielectric continuum model; molecular solvent; Stockmayer fluid; electrical double layer; ion-ion correlations; Monte Carlo simulations; thermodynamic modeling; pressure curves; interaction free energy; packing effects;

    Sammanfattning : The dielectric continuum model has rightfully been and continues to be a major workhorse for theory and modelling in Surface and Colloid Chemistry. Due to the implicit description of water, entering only as a scaling constant for charge-charge interactions, one would not expect it to work for short distances. LÄS MER

  5. 4. Effect of hydration on thermodynamic, rheological and structural properties of mucin

    Författare :Yana Znamenskaya; Malmö högskola; []
    Nyckelord :mucous gel; mucus; mucin; PGM; BSM; BSM chitosan multilayers; hydration; water sorption isotherm; relative humidity; water activity; bound water; enthalpy of hydration of biopolymer; glass transition; rheology; phase diagram; fiber-like structure; dumbbell-like structure; sorption calorimetry; DSC; QCM-D; SAXS; AFM;

    Sammanfattning : Mucus, an adherent hydrated layer covering the epithelium, is found in all internal tracts of the body and plays an important role in animal and human life. One of the essential functions of mucus is protection of tissues against dehydration. LÄS MER

  7. 5. On thermodynamic properties of aqueous ethylamine mixtures and modelling of excess properties

    Författare :Åsa Ulrika Burman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Ethylenediamine (EDA) is a bifunctional amine used for several different purposes such as for production of the Ethylenediaminetetracetric acid (EDTA) that is used as a chelating agent in detergents but also for fungicides, bleaching activators etc. In many applications very high purity is needed and the removal of the byproduct Ethylethylenediamine (EtEDA) has proven to be difficult.
