  1. 21. Hydrogen Storage Materials : Design, Catalysis, Thermodynamics, Structure and Optics

    Författare :Carlos Moysés Graça Araújo; Rajeev Ahuja; Ole Martin Løvvik; Uppsala universitet; []
    Nyckelord :Materials science; Hydrogen-storage materials; Density functional theory; Molecular dynamics; Catalysis; Thermodynamics; Optics; Materialvetenskap;

    Sammanfattning : Hydrogen is abundant, uniformly distributed throughout the Earth's surface and its oxidation product (water) is environmentally benign. Owing to these features, it is considered as an ideal synthetic fuel for a new world energetic matrix (renewable, secure and environmentally friendly) that could allow a sustainable future development.

  3. 22. Studies in Physiological Optics and Microwave Hyperthermia

    Författare :Claes M. E. Beckman; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optics; cancer treatment; light scattering;

    Sammanfattning : This thesis deals with the optics of the eye, the sky and microwave induced hyperthermia treatment of cancer. Light scattering in normal eyes is reviewed and its influence on vision is discussed in some detail. LÄS MER

  4. 23. Quantum Optics with Propagating Microwaves in Superconducting Circuits

    Författare :Io Chun Hoi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transmon; second-order correlation function; qubit; microwave photons; photon router; superconducting artificial atom; Autler-Townes splitting; quantum network; SQUID; superconducting circuits; cross-Kerr effect; antibunching; Mollow triplet; Josephson junction; quantum optics;

    Sammanfattning : We address recent advances in quantum optics with propagating microwavesin superconducting circuits. This research field exploits on the fact that the coupling between a superconducting artificial atom and propagating microwave photons in a one-dimensional (1D) open transmission line can be made strong enough to observe quantum effects, without using any cavity to confine the microwave photons.

  5. 24. Optics Corrections and Stabilization Methods for Particle Accelerators

    Författare :Tobias Persson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LHC; accelerators; beam optics; ; feedback; CTF3; optics correction; CLIC;

    Sammanfattning : The discovery of a Higgs-like particle is the result of excellent performance ofboth the LHC (Large Hadron Collider) and its detectors. A significant partof the success can be attributed to the excellent control of the optics in theaccelerator. In this thesis the methods used to correct the optics functions arepresented. LÄS MER

  7. 25. Compact Soft X-Ray Microscopy : Sources, Optics and Instrumentation

    Författare :Per Takman; Hans Hertz; Janos Kirz; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; soft x-ray microscopy; water window; compact; laser plasma; liquid jet; zone plate optics; Physics; Fysik;

    Sammanfattning : This thesis describes the development of a sub-60-nm full-period resolution compact soft x-ray microscope operating in the water-window region (2.3-4.4 nm). Soft x-ray water-window microscopy is a powerful technique for high-resolution imaging of organic materials exploiting the natural contrast mechanism between carbon and oxygen, cf. LÄS MER
