  1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Author : Grigore-Leon Ratiu; [2024]
    Keywords : Physics and Astronomy;

    Abstract : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. READ MORE

  2. 2. Formulation development, rheological characterization, and cosmetic evaluation of gel-creams

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Carl Pontén; [2024]
    Keywords : Rheology; Texture analysis; Viscometry; Semisolids; Design of Experiments; Critical Process Parameters; Critical Quality Atttibutes; Pharmaceutical Technology; Technology and Engineering;

    Abstract : Oil in water (o/w) emulsions are thermodynamically unstable systems composed of small oil droplets dispersed in a continuous aqueous phase. This means that given enough time, the two phases will separate. Pharmaceutical emulsions are used as a method of administering the Active Pharmaceutical Ingredient (API) for topical applications.

  3. 3. Investigation of Ice Nucleating Particles (INPs) in southern Sweden - With a special focus on their origin, possible connection to meteorological parameters and aerosol properties

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Malin Forsmalm; [2023-06-21]
    Keywords : INPs; DFA; LUCS;

    Abstract : This study investigates if there is a seasonal variability of ice nucleating particle (INP) concentrations. There is also a focus in seeing if there are correlations between meteorological parameters and aerosol properties and the measured INP concentrations. READ MORE

  4. 4. Influence of pulsing on PVD TiAlN coating microstructure and mechanical properties : Master thesis project on the impact of deposition parameters on performance and properties of PVD titanium aluminum nitride.

    University essay from Karlstads universitet

    Author : Marcus Roseen; [2023]
    Keywords : ;

    Abstract : This thesis investigates the influence of pulsing on the mechanical properties of PVD TiAlN coatings. The thesis focuses on defects caused by droplets during the arc-evaporation technique by altering the duty time, which affects mechanical properties. READ MORE

  5. 5. The effect of high pressure homogenization on emulsions containing oat β-glucan : a study of viscosity, stability and molecular weight

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Dominika Kiesling; [2023]
    Keywords : oat; β-glucan; high pressure homogenization; emulsion; stability; food technology; Agriculture and Food Sciences;

    Abstract : This master thesis project has been conducted in cooperation with Lantmännen AB who are producers of PromOat® - an oat β-glucan powder concentrate. The main objective of this thesis was to investigate the properties of emulsions containing PromOat® oat β-glucan, focusing on the viscosity, stability, and molecular weight before and after high pressure homogenization (HPH) at pressures of 100, 150 and 200 bars.
