  1. 1. Growing on the roof : But in what? Examing substrates/growing media for rooftop farming

    Kandidat-uppsats, SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Författare :Mikael Brocki; [2023]
    Nyckelord :urban rooftop agriculture; URTA; green roof; substrate; growing medium; organic matter; compost; vegetable; crop; yield; lettuce; tomato; pore; pore-size distribution;

    Sammanfattning : Urban Rooftop Agriculture (URTA) is a novel field within urban vegetable production, which can help create access to local food in a rapidly urbanizing world. For these systems to succeed, it is vital to implement a proper choice of substrate/growing medium (SGM). LÄS MER

  3. 2. Deterministic Nanopatterning of Graphene Using an Ion Beam

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad kärnfysik

    Författare :Henrik Bruce; [2022]
    Nyckelord :nanofabrication; lithography; nanopatterning; nanoporous graphene;

    Sammanfattning : Graphene features a unique combination of exceptional properties and has emerged as one of the most promising nanomaterials for a variety of applications. The ability to structurally modify graphene with nanoscale precision enables the properties to be further extended. LÄS MER

  4. 3. How much can the cross-linking of chromatographic media affect the porosity?

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Carl Östling; [2022]
    Nyckelord :Liquid chromatography; Size exclusion chromatography; Agar; Chromatographic resins; Distribution coefficient; Vätskekromatografi; Storleksuteslutningskromatografi; Agar; Stationär fas; Fördelningskoefficient;

    Sammanfattning : Vätskekromatografi är vanligt förekommande metod för separationer av molekyler inom bioteknik. Det finns inom begreppet vätskekromatografi många olika tekniker och vilken specifik teknik som är mest lämplig för en given separation beror på egenskaperna hos den avsedda målmolekylen. LÄS MER

  5. 4. An Overview of State-of-the-art Hydraulic Conductivity Measurements in Coarse Grained Materials

    Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Jakob Andrén; [2021]
    Nyckelord :hydraulic conductivity; permeability; embankment dam; coarse grained; flow regime; hydraulisk konduktivitetsmätning; permeabilitet; fyllnadsdamm; grovkorniga material; flödesregim;

    Sammanfattning : Embankment dams are made from soil materials of varying sizes and widely used all over the world.When constructing these, knowing the hydraulic conductivity (K) of the soil materials is a keyparameter in order to construct safe embankment dams. A knowledge gap regarding K measurementsin coarse grained soils has been identified. LÄS MER

  7. 5. Modelling the impacts of organic matter quality on soil carbon turnover and storage : continued testing of a novel dual-pore model against data collected from a long-term study site in Offer, Sweden

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

    Författare :Mikael Sasha Dooha; [2021]
    Nyckelord :soil; soil organic matter; carbon; carbon sequestration; tillage; land-use; soil structure; porosity; modelling; humification;

    Sammanfattning : As we look for solutions to the worsening climate crisis, carbon sequestration has become a popular strategy to mitigate CO2 emissions. Carbon models are used to predict or emulate changes in future soil organic carbon (SOC) stocks, but most fail to account for the influence of pore size on soil structure and SOC storage. LÄS MER
