  1. 1. Phase and Interface Design in Potential Earth-Abundant Multi-Component Photocatalysts

    L3-uppsats, Lunds universitet/Kemiska institutionen

    Författare :David Llorens Rauret; [2022]
    Nyckelord :Facet control; in-situ TEM; nanoparticle heterostructures; phase transformation; transition metal phosphides; inorganic nanomaterials; Chemistry;

    Sammanfattning : Transition metal phosphides are low-cost, earth-abundant semiconductors with promising properties for photocatalysis, including water-splitting. When combined with other semiconductors or noble metals in nanoparticles, their photocatalytic performance can be drastically enhanced. LÄS MER

  3. 2. Colliding Galaxies in a (Nut)Shell

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Författare :Jonathan Petersson; [2022]
    Nyckelord :shell galaxies; simulations; starbursts; quenching; mergers; Physics and Astronomy;

    Sammanfattning : Galaxy interactions and mergers are natural recurring events in the current cosmological paradigm, events that often coincide with starbursts and enhanced star formation activity. To understand why that is, one can use idealised (non-cosmological) merger simulations, which provide freedom to recreate specific tidally distorted galaxies, and analysis of the time evolution and underlying physics of the star formation activity at a high spatial resolution.

  4. 3. Greenhouse gas emissions from compacted peat soil

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Antonia Hartmann; [2021]
    Nyckelord :carbon dioxide; compression index; Peatland agriculture; recompression index; sand addition; soil compaction;

    Sammanfattning : Cultivated peat soils are a main driver for CO2 and N2O emissions, while the gas fluxes are dependent on intrinsic soil properties and land use. Sand addition into peat soils might reduce greenhouse gas (GHG) emissions and enhance soil strength, and thus the ability to tolerate soil compaction. LÄS MER

  5. 4. Fysisk hälsa bland professionella eSportare

    Master-uppsats, Umeå universitet/Avdelningen för fysioterapi

    Författare :Staffan Ekefjärd; [2020]
    Nyckelord :esport; hälsa; fysiska symtom; smärta; träning; sömn; skärmtid;

    Sammanfattning : Introduktion: ESport är en snabbt växande sport med miljontals utövare världen över. Gällande hälsa och eSport är den mentala biten med gaming syndrome och utveckling av kognitiva funktioner klart mer beforskad än den fysiska hälsan. LÄS MER

  7. 5. Effects of 100 years of drainage on peat properties in a drained peatland forests in northern Sweden

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Mikaela Casselgård; [2020]
    Nyckelord :ash content; biodiversity; bulk density; carbon; climate; compaction; ditch; drainage; greenhouse gas emissions; groundwater level; isotopes; nitrogen; peatland; restoration;

    Sammanfattning : Natural peatlands provide a small but persistent long-term carbon (C) sink. However, within the last century their extent in Sweden has declined by about 1.5-2.0 million hectares due to drainage activities. LÄS MER
