  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. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

    University essay from KTH/Materialvetenskap

    Author : Christopher Hallén; Marcus Johansson Storne; [2023]
    Keywords : ;

    Abstract : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. READ MORE

  4. 3. Study of vector control strategy on Interior Permanent Magnet Synchronous Motors

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

    Author : Prabhu Bernard; [2023]
    Keywords : Direct Torque Control; IPMSM; implementation; performance;

    Abstract : This thesis presents a comprehensive study of Direct Torque Control (DTC) for Interior Permanent Magnet Synchronous Motors (IPMSMs) evaluating its potential in high performance motor drive systems. The research begins with a literature review, looking into the fundamental principles of DTC, Pulse Width Modulation (PWM), Space Vector Modulation (SVM) and Field Oriented Control (FOC). READ MORE

  5. 4. Enabling a Circular Economy with Digital Product Passports: Information Requirements and Data Collection Practices

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