  1. 1. Tritrophic interactions with Silphium integrifolium at the axis : elucidating the role of arbuscular mycorrhizal fungal species on plant phenotype

    Master-uppsats, SLU/Dept. of Plant Protection Biology

    Författare :Philipp Hansen; [2023]
    Nyckelord :Arbuscular mycorrhiza; mycorrhizal responsiveness; induced plant volatiles; Silphium integrifolium Silflower ; perennial grains; new crops; ecological intensification;

    Sammanfattning : A fundamental understanding of the intricate interactions between crops and their environment may help guide the development of ecologically intensified agriculture. Arbuscular mycorrhizal fungi (AMF) are root symbionts that can increase a plant’s access to soil resources and have been found to reprogram plant defensive mechanisms, potentially influencing the performance of plant antagonists.

  3. 2. Purification of Volatile Organic Compounds in Channeled Ventilation Pipes at the Sysav Water Treatment Plant for Hazardous Waste

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Erik Wiktorsson; [2022]
    Nyckelord :VOC; Zeolite; Catalytic combustion; Sysav; Chemical Engineering; Chemistry; Technology and Engineering;

    Sammanfattning : Several channeled emissions at the Sysav water treatment plant for hazardous waste as of December 2021 exceed permitted levels of unknown volatile organic compounds (VOCs) stated in the European Parliament councils’ directives 2010/75/EU. A range of possible treatment methods are briefly discussed before zeolite adsorption, and thermal regeneration followed by catalytic combustion is decided to be the method of greatest feasibility and is the subject of further investigation.

  4. 3. Film formation of mixed-halide perovskites for PSCs

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Lina Ekstedt; [2021]
    Nyckelord :Mixed Halide Perovskites; Perovskite Solar Cells; Bandgap Tuning; In-situ Spectroscopy; Antisolvent; Interface Modifier.; Physics and Astronomy;

    Sammanfattning : Over the last few years there has been a steady increase in interest in the exploration of perovskite materials within photovoltaic research. This can to a large extent be attributed to the incredible pace at which solar cells based on perovskites have improved in efficiency during the same time period. LÄS MER

  5. 4. Advanced rear contact design for CIGS solar cells

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jorge Alexandre De Abreu Mafalda; [2019]
    Nyckelord :CIGS; HfO2; surface passivation; alkali treatment; point contact openings; SCAPS;

    Sammanfattning : The current trend concerning the thinning of solar cell devices is mainly motivated by economic aspects, such as the cost of the used rare-earth elements, and by the requirements of emergent technologies. The introduction of ultra-thin absorber layers results in a reduction of used materials and thus contributes to a more cost-effective and time-efficient production process. LÄS MER

  7. 5. Impact of plant ecotype on Bacillus-mediated growth promotion : extending beyond the standard model plant

    Master-uppsats, SLU/Dept. Of Plant Biology

    Författare :Staffan Matzén; [2018]
    Nyckelord :bacillus; growth promotion; root exudates; volatiles;

    Sammanfattning : This study investigated how bacterial treatment modulates plant growth. Bacillus amyloliquefaciens UCMB5113 was used for treatment of several different natural accessions (ecotypes) as well as mutants of Arabidopsis thaliana. Treatment effect on plant root architecture was studied in particular. LÄS MER
