  1. 21. Synthesis of framework porous sorbents using sustainable precursors

    University essay from Uppsala universitet/Nanoteknologi och funktionella material

    Author : Oskar Hellman; [2021]
    Keywords : Metal organic framework; green synthesis; carbon capture; gas adsorption;

    Abstract : Metal organic frameworks (MOFs) is a quite recently discovered porous material group which shows potential in many different areas. One of these areas is carbon capture; the framework structure of the porous materials allows gas molecules to adsorb to the surface of the pores. READ MORE

    Keywords : Common reed; Phragmites australis; Giant reed; Arundo donax; Usage; Utilization; Baltic sea; Sweden; Eutrophication; Overfertilization; Nutrient discharge; Blue bioeconomy; Soil improvement; Feedstock; Pyrolysis; Biochar; Biocoal; Coal supplement; Bioenergy; Biofuel; Carbon sequestration; Fodder; Cost analysis; Bladvass; Phragmites australis; Italienskt rör; Arundo donax; Användning; Användningsområde; Östersjön; Sverige; Eutrofiering; Övergödning; Näringsläckage; Blå bioekonomi; Jordförbättring; Råmaterial; Pyrolys; Biokol; Bioenergi; Biobränsle; Kolbindning; Foder; Kostnadsanalys;

    Abstract : The climate on earth keeps getting warmer where heat waves, eutrophication, rising sea levels, extreme weather like flooding, droughts and wildfires are an expanding problem. The focus of this bachelor thesis is to determine the potential of mitigating eutrophication and while contributing to blue growth by harvesting and make use of reeds like Phragmites australis and Arundo donax.

  4. 23. Evaluating the potential of microplastics and natural organic matter for sorption of hydrophobic organic contaminants based on selected properties

    University essay from SLU/Dept. of Aquatic Sciences and Assessment

    Author : Sabrina Noël Reaume Zabalgoitia; [2021]
    Keywords : microplastics; natural organic matter; particulate organic matter; sorption; vector;

    Abstract : Interest in microplastic behaviour as vectors for hydrophobic organic pollutants has increased in the literature over recent years, however these materials constitute only one of many organic particulate groups in the environment able to compete for pollutants. This review examines particle characteristics including size, surface area, porosity, and age, and how these may influence natural organic particle and microplastic sorption capacity. READ MORE

  5. 24. Influence of cropping and fertilization on soil pore characteristics in a long-term field study

    University essay from SLU/Dept. of Soil and Environment

    Author : David Nimblad Svensson; [2020]
    Keywords : X-ray CT; soil structure; biopores; connectivity;

    Abstract : Soil porosity, pore size distribution and pore characteristics such as connectivity are important for a range of soil processes including ease of root growth and air and water transport. The pore structure is therefore an important part of soil fertility. READ MORE

  6. 25. The thermal insulating effects of Quartzene® on painting systems

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Arwin Zendehrokh; Luis Mariscal; Martin Hunhammar; Ismail Yussuf Hassan; Albert Pettersson; [2020]
    Keywords : aerogel; quartzene; insulation; nanoparticles; paint; Transient plane source; TPS; thermal conductivity;

    Abstract : The European Green Deal 2020 goals for reducing emissions are enforcing rules on the energy performance of buildings. Therefore thermally insulating materials used as coatings are researched to reduce the energy emissions of buildings. An essential field of interest are nanomaterials. READ MORE
