  1. 1. A novel approach for functionalising and separating Tröger's Base Analogues

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Emil Jakobsson; [2023]
    Keywords : Tröger s Base; Synthesis; Chromatography; Supramolecular chemistry; Diastereomers; Organic chemistry; Chemistry;

    Abstract : Tröger’s Base (TB) is a bicyclic compound containing a methanodiazocine group between two aromatic rings. The methylene bridge forces the molecule to have a bent formation; thus, the aromatic rings are close to 90 degrees relative to each other, resulting in a rigid concave aromatic cavity. READ MORE

  3. 2. Phase and Interface Design in Potential Earth-Abundant Multi-Component Photocatalysts

    University essay from Lunds universitet/Kemiska institutionen

    Author : David Llorens Rauret; [2022]
    Keywords : Facet control; in-situ TEM; nanoparticle heterostructures; phase transformation; transition metal phosphides; inorganic nanomaterials; Chemistry;

    Abstract : Transition metal phosphides are low-cost, earth-abundant semiconductors with promising properties for photocatalysis, including water-splitting. When combined with other semiconductors or noble metals in nanoparticles, their photocatalytic performance can be drastically enhanced. READ MORE

  4. 3. Micro-CT based finite element models for mechanical strength assessment of glass ceramic scaffolds obtained through the robocasting technique

    University essay from KTH/Hållfasthetslära

    Author : Gustav Thessén; [2022]
    Keywords : µ-CT modelling; phase-field method; bio-glass scaffolds; strength assessment; Mikrotomografi; μ-CT; fasfältsmetoden; bio-glas stödstrukturer; brottgräns;

    Abstract : In this thesis, micro computed tomography (μ−CT) scans of a bio-glass scaffold produced by the robocasting technique was used to create finite element method (FEM) models with the purpose of determining its mechanical strength. Prior to this, a Matlab script was used to create several simplified geometries of the scaffold in an effort to determine the importance of scaffold design parameters (such as the fiber compenetration between two adjacent printing planes) on the strength of the scaffold.

  5. 4. Modelling of air-gap harmonic torques and its impact on vibrations in electric drivetrains : Modelling interaction between electromagnetics and vibration of an electrical machine

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Dhiyanesh Radhakrishnan; [2021]
    Keywords : Electro-Magnetics; Eigenfrequency; Electrical Machine; Multi-Body Dynamics; Displacement; machine vibrations; Elektromagnetik; Eigen frekvens; Elektrisk maskin; Flerkropps dynamik; Förskjutning; maskin vibrationer;

    Abstract : In this report, the effect of external torque injection of a particular phase and frequency was analyzed using an induction motor assembly consisting of a prototype of an induction motor and a flexible mounting arrangement. The eigenfrequencies of the several components that make up the construction of the induction machine assembly are found out both by analytical and FEM methods. READ MORE

  6. 5. Fast Pyrolysis of Biomass in a Fluidized Bed for Production of Bio-oil and Upgradation by Ex-situ Catalytic Bed

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Samina Gulshan; [2019]
    Keywords : ;

    Abstract : Production of bio-oil from biomass is now becoming best substitute of fossil fuels in the transportation sector. Pyrolysis is one of the most promising route to produce bio-oil from biomass.  However, bio-oil needs to be upgraded due to presence of high percentage of oxygenated compounds. READ MORE
