  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

  3. 2. Exploratory study of additively manufactured heat exchangers for aerospace applications

    University essay from

    Author : Siddharth Nadukkandy; [2023]
    Keywords : ;

    Abstract : Thermal management is a crucial part in the aviation industry. It is also essential that the components involved in aviation be light weight. One of the vital components of thermal management is heat exchangers. It has been observed that the optimization of the heat exchanger is approaching its saturation with traditional manufacturing.

  4. 3. Study of Triply Periodic Minimal Surfaces for Heat Transfer Applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : María Xuan Celaya Granados; [2023]
    Keywords : ;

    Abstract : In the pursuit of enhancing heat exchanger efficiency, several heat transfer- enhancing strategies are employed. The traditional methods include surface vibrations, microchannels, and integration of vortex generators. Additionally, new solutions are being studied, taking advantage of other relevant improve- ments in the engineering field. READ MORE

  5. 4. Feasibility Study of X-ray Free Electron Lasers in Fourth Generation Storage Rings

    University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/MAX IV-laboratoriet

    Author : Jordis Hansen; [2023]
    Keywords : XFEL; Storage Ring; Synchrotron Radiation; Physics and Astronomy;

    Abstract : This thesis studies the feasibility of a cavity based X-ray free electron laser in a fourth generation storage ring. The cavity design allows for modulation of the electron beam over several passes through the undulator. Simulations based on the PETRA IV facility are done to create the photon flux spectrum of a light pulse produced by an undulator. READ MORE

  6. 5. Friezes, Triangulations, and Trees

    University essay from Lunds universitet/Matematik LTH; Lunds universitet/Matematik (naturvetenskapliga fakulteten); Lunds universitet/Matematikcentrum

    Author : Yijia Zeng; [2023]
    Keywords : Frieze pattern; polygon triangulation; binary tree; Catalan numbers; Mathematics and Statistics;

    Abstract : In this thesis, we focus on these three classes of objects: frieze patterns, polygon triangulations, and planar binary rooted trees. After proving that these objects are in pairwise bijective correspondence with each other, we introduce Catalan numbers through Dyck paths and prove that all these objects are Catalan objects.
