  1. 1. Development of Inlet Valve in an Oil­-free Novel Steam Engine

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Gautam Rajeev; Dinesh Thirunavukkarasu; [2021]
    Keywords : Steam engine; rotational valve; actuator mechanism; sealing; Ångmotor; rotationsventil; ställdon; tätning;

    Abstract : A novel compact steam engine design could be used to replace current combustion engines in the rapidly changing world of renewable energy. Especially with the increased research into alternative fuels such as hydrogen fuel cells and methane, which would vastly improve the efficiency of a steam engine. READ MORE

  3. 2. Relativistic attosecond electron pulses by laser wakefield acceleration

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

    Author : Cornelia Gustafsson; [2020]
    Keywords : laser wakefield accelerator; laser wakefield acceleration; attosecond; electron pulses; Physics and Astronomy;

    Abstract : The search for cheaper and more compact accelerators has led to the development of laser-driven plasma-based accelerators. In comparison to conventional particle accelerators, the plasma-based accelerator is inherently insensitive to the breakdown of the acceleration structure and therefore greater accelerating fields can be obtained.

  4. 3. Angular dependence of the Raman active phonon modes of Black Phosphorus

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

    Author : Armand Dominguez; [2019]
    Keywords : Black Phosphorus; Raman Spectroscopy; Physics and Astronomy;

    Abstract : This Master’s project presents on the angular dependence of the intensity of the Raman active phonon modes of Black Phosphorus (BP), a layered 2D material with unique and attractive characteristics to the scientific and engineering community. Raman spectroscopy is an indispensable tool in quick and unobtrusive analysis of chemical structures. READ MORE

  5. 4. Simulating Quantum Cascade Lasers with the Position and Energy Resolving Lindblad approach

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

    Author : Maitane Muñoz Basagoiti; [2019]
    Keywords : quantum cascade lasers; quantum transport; simulations; electron transport; Physics and Astronomy;

    Abstract : Over the past two decades, Quantum Cascade Lasers (QCLs) have become an increasingly popular source for mid-infrared and terahertz radiation. Nowadays, their experimental development progresses fast with the aid of computer simulations. These reproduce carrier dynamics in the gain medium of the laser based on different transport models.

  6. 5. All solid state single-shot Dispersion scan (D-Scan) for ultrashort laser pulses

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

    Author : Shekhar Jadhav; [2019]
    Keywords : Dispersion scan; d-scan; Single shot d-scan; Si-scan; Physics and Astronomy;

    Abstract : Ultrashort laser pulses play an important role in many applications in science and technology, from attosecond science to time resolved spectroscopy and material processing. For applications of ultrashort laser pulses, it requires a complete characterization of the electric field of the pulse, which includes both phase and amplitude of the electric field. READ MORE
