  1. 21. Three-body decay as a baryon polarizer

    University essay from Uppsala universitet/Kärnfysik

    Author : Carl Johan Königsson; [2023]
    Keywords : Three-body decay; polarization; CP violation; hyperon; resonance; Trekroppssönderfall; polarisation; CP-brytning; hyperon; resonans;

    Abstract : According to the standard model, the size of CP violation in the weak decay Λ → pπ- is predicted to be ∼ 10-5. This means that a very high precision is needed if we want to be able to measure it. READ MORE

  3. 22. Modified cellulose synthesized by different deep eutectic solvents as an additive in paper making process

    University essay from Karlstads universitet

    Author : Shiniar Said Saleh; [2023]
    Keywords : green chemistry; dry strength additives; deep eutectic solvents; sodium periodate oxidation; charge density; dewatering; mechanical strength.;

    Abstract : The environmental concerns that come with the currently used traditional papermaking process where petroleum-based additives are used, has tempted researchers to study “green” additives by introducing environmentally friendly modifications of cellulose as an additive in the papermaking process. This thesis will spin further on that by producing additives with different charge densities and focus on to incorporate an etherification reaction into potentially greens systems based on non-toxic and readily biodegradable deep eutectic solvent (DES).

  4. 23. Design and engineering of light-driven dynamic films for bioelectronic interfacing

    University essay from KTH/Tillämpad fysik

    Author : Luca Terenzi; [2023]
    Keywords : Conductive polymers; Stimuli responsive materials; Azopolymers; Cell-chip coupling; Bioelectronics; Konduktiva polymerer; Stimuli-känsliga material; Azopolymerer; Cell-chip-koppling; Bioelektronik;

    Abstract : In the realm of neuroelectronics, the challenge lies in achieving finer observations of physiological processes to comprehend neuronal interactions and computations. This necessitates the development of more compliant and biomimetic interfaces for improved integration with biological tissues, enabling finer physiological process observations. READ MORE

  5. 24. Investigation of a newrepresentation of spin

    University essay from Uppsala universitet/Materialteori

    Author : Minna Palmgren Thun; [2023]
    Keywords : Material theory; Spin; Statistical physics; Second quantization; Materialteori; spinn;

    Abstract : The Bose-Hubbard Model, a tight binding model within solid state theory can be solved exactly using a number theoretical approach. From this approach, in the two sited Bose-Hubbard model, the hopping term in the model takes the form of a Pauli x matrix. The hopping term can be interpreted as a two energy level system or a dimer with k+1 particles. READ MORE

  6. 25. Improving polarizing neutron optics by introducing 11B4C as interlayers

    University essay from Linköpings universitet/Tunnfilmsfysik

    Author : Martin Falk; [2023]
    Keywords : Thin film multilayers; Neutron optics; Neutron polarization;

    Abstract : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. READ MORE
