  1. 1. Thermal Conversion of Cellulose-Lignin Precursors into Carbon Fibres

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Sofia Westberg; [2023]
    Keywords : Carbon fiber; lignin; cellulose; continuous conversion;

    Abstract : Carbon fibres are used in many applications thanks to their exceptional tensile properties in relation to their relatively low weight. These thin strands of at least 90% carbon are mixed with a matrix such as epoxy to form composites used for cars, wind turbines, prosthetics, and many other things. READ MORE

  3. 2. Simulation, Design, and Implementation of a Narrow Linewidth Ytterbium Fiber MOPA System at 1087 nm

    University essay from KTH/Tillämpad fysik

    Author : Berkay Efilti; [2023]
    Keywords : Applied Physics; Laser Physics; Fiber Lasers; Fiber Amplifiers;

    Abstract : This thesis focuses on simulating, designing, and characterizing a narrow-linewidth continuous-wave (CW) Ytterbium (Yb) master oscillator fiber amplifier (MOFA) system. The primary goal was to achieve a watt-level output at 1087 nm with a narrow 1 GHz linewidth, making the MOFA well-suited for serving as a pump source in Terahertz (THz) generation experiments.

  4. 3. Enhancing Mineral Carbonation of Olivine with CO2

    University essay from KTH/Kemiteknik

    Author : Ikaros Altantzis; [2023]
    Keywords : CO2 sequestration; Dissolution rate; Mineral carbonation; Olivine; Particle size; CO2-inlagring; Upplösningshastighet; Mineral kolsyrning; Olivin; Partikelstorlek;

    Abstract : Koldioxidutsläpp (CO2) från energiproduktionsindustrin och transportsektorn globalt påverkar miljön negativt. Länder har enats om att minska utsläppen för att nå målet om en genomsnittlig temperaturökning på 1,5 °C till 2030. READ MORE

  5. 4. Continuous Quantum Control of Quantum Dot Systems

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Daniel Holst; [2022]
    Keywords : Quantum Control; Quantum Fokker-Planck Master Equation; Maxwell s demon; Quantum dots; Full counting statistics; Generalized Quantum Measurements; Thermodynamics; Physics and Astronomy;

    Abstract : Control and feedback operation of quantum systems have in recent years gained a lot of interest since they are fundamental to achieving functional quantum information processing systems but also of great importance in applications of information to energy conversion within quantum thermodynamics. This thesis has treated a new formalism for feedback control of quantum systems. READ MORE

  6. 5. Omställning till hyggesfritt skogsbruk – föryngring i skog som ställts om från trakthyggesbruk till blädningsbruk

    University essay from SLU/School for Forest Management

    Author : Ida Pontén; Ludvig Renell; [2022]
    Keywords : plantetablering; omföring; markstörning;

    Abstract : Skogsstyrelsen har fått uppdraget att öka kunskapen och användandet av hyggesfria metoder i det svenska skogsbruket. För att hyggesfri skogsskötsel ska kunna bli vanligare behöver skog som tidigare skötts med trakthyggesbruk istället börja skötas med hyggesfria metoder. READ MORE
