  1. 1. Sustainable use of calcium nitrate fertilizer under variable precipitation, soil properties and crop management

    University essay from SLU/Dept. of Soil and Environment

    Author : Liliana Marcela Daza Gomez; [2023]
    Keywords : nitrogen.; calcium nitrate; ammonium-based fertilizers; urea; nitrate leaching; nitrous oxide emissions; crop yield;

    Abstract : Application of nitrogen fertilizers in agriculture contributes substantially to global greenhouse gas emissions and nitrogen leaching. Accordingly, there is a need to increase knowledge about sustainable farming practices to reduce nitrogen losses to the environment without curtailing crop harvest. READ MORE

  3. 2. Membrane-less porous walls electrolyzer for electrochemical ammonia synthesis

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Francesco Gelain; [2023]
    Keywords : electrochemical ammonia synthesis EAS ; nitrate reduction; green ammonia; energy storage; hydrogen carrier.; elektrokemisk ammoniaksyntes; nitratreduktion; ammoniak; grön ammoniak; energilagring; vätgasbärare.;

    Abstract : n a world of unsustainable growth and increasingly catastrophic climate events, the quest for sustainability is open. Electrochemical ammonia synthesis (EAS) represents an eco-friendly means for green ammonia production. READ MORE

  4. 3. Modelling the full-scale N2O emissions from wastewater treatment plants for identifying mitigation strategies

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Naga Deepika Peddamudium; [2023]
    Keywords : Modelling; simulation; ASM2dISS; N2O production pathways; N2O emission factor; mitigation strategies; water and environmental engineering; Technology and Engineering;

    Abstract : Nitrous oxide (N2O) emissions, which primarily originate from the biological nitrogen removal process, dominate the release of greenhouse gases (GHGs) in wastewater treatment plants (WWTPs). N2O production occurs through dynamic microbial pathways that have a significant impact on the environment compared with other GHG emissions. READ MORE

  5. 4. The Use of Gels for the Removal of Cellulose Nitrate Lacquer on Silver

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Miri Katayon; [2022-07-05]
    Keywords : agar gel; metal conservation; nanomaterials; silver coating; sustainable conservation; varnish removal;

    Abstract : The conservation of silver objects mainly constitutes addressing the issues of tarnish removal and of preventing tarnish. For decades lacquer has been used to coat silver objects in order to protect them from tarnishing. READ MORE

  6. 5. Explicit consideration of microbes in quantification of gross N rates based on N-tracing model

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Tsai-wei Tang; [2022-01-26]
    Keywords : N-tracing model; microbial biomass; gross N quantification; organic N; mineralization; immobilization;

    Abstract : When studying the nitrogen cycle in soils, the principle of 15N isotope dilution and enrichment is commonly used to measure gross N transformation rates. The measuring data of both organic and inorganic nitrogen substrates are therefore be analysed by Ntrace model. READ MORE
