  1. 16. Additive manufacturing of lunar regolith simulant using direct ink writing

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Billy Grundström; [2020]
    Keywords : 3D printing; additive manufacturing; lunar regolith simulant; european space agency; ESA; in situ resource utilisation; ISRU; direct ink writing; sintering;

    Abstract : In this work, the use of a lunar regolith simulant as feedstock for the direct ink writing additive manufacturing process is explored, the purpose of which is to enable future lunar in-situ resource utilisation. The feasibility of this approach is demonstrated in a laboratory setting by manufacturing objects with different geometries using methyl cellulose or sodium alginate as binding agents and water as liquid phase together with the lunar regolith simulant EAC-1A to create a viscous, printable ‘ink’ that is used in combination with a custom three-axis gantry system to produce green bodies for subsequent sintering.

  3. 17. Bindning av PFAS-ämnen till humus- och fulvosyror : en dialysstudie

    University essay from SLU/Dept. of Soil and Environment

    Author : Johannes Kikuchi; [2020]
    Keywords : PFOS; PFOA; sorption; kinetics; dissolved organic matter; natural organic matter; DOC; DOM; membrane;

    Abstract : To make more accurate predictions of the mobility of perfluoroalkyl substances (PFAS) in soil and water, better understanding of PFAS sorption to components of the terrestrial and aquatic systems is needed. This study investigated the possible sorption of a range of PFAS compounds with varying chemistries to humic acid (HA) and fulvic acid (FA) using a dialysis bag experimental set-up. READ MORE

  4. 18. Alternative oxidase respiration in the mycorrhizal fungus Laccaria bicolor

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Hilda Mikaelsson; [2019]
    Keywords : L. bicolor; mycel; ektomykorrhiza; cellandning; AOX; alternativt oxidas; cytokromoxidas; cyanid; mycelium; ectomychorriza; respiration; alternative oxidase; cytochrome oxidase; salicylhydroxamic acid; n-propyl gallate; cyanide;

    Abstract : The temperature on Earth is rising, and one of the main drivers is anthropogen-ic greenhouse gases such as carbon dioxide (CO2). The world’s forests act as carbon sinks, binding carbon into their biomass. The net carbon assimilation is determined by the uptake and release of CO2 through the processes of photo-synthesis and respiration. READ MORE

  5. 19. Artificial photosynthesis - 4-Aminobenzoic acids effect on charge transfer in a photo catalytic system

    University essay from Uppsala universitet/Materialteori

    Author : Simon Moberg; [2019]
    Keywords : artificial photosynthesis; aminobenzoic acid; charge transfer; plasmon; induced; plasmon induced; nanostructure; nanostructures; solar energy; nano particles; nano particle; artificiell fotosyntes; aminobensoesyra; laddningsöverföring; plasmon; inducerad; plasmoninducerad; nanostruktur; nanostrukturer; solenergi; nanopartiklar; nanopartikel;

    Abstract : Artificial photosynthesis is used to harvest solar energy and store it in the form of chemical bonds. The system of interest in this study does this by splitting water into hydrogen and oxygen gas through a plasmon assisted process, collective oscillations from free electron gas. READ MORE

  6. 20. How can Ecosystem Services be implemented in local Climate Adaptation? : A case study of Arjeplog

    University essay from Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggande

    Author : Jenny Boltemo Edholm; [2019]
    Keywords : ecosystem-based adaptation; ecosystem services; local planning; resilience; climate change;

    Abstract : Ecosystem services are essential for human climate adaptation. As climate change is a direct driver of change for ecosystem service provisioning, it is of importance to care for our ecosystems to be able to cope with future challenges. Local governance has a central role in climate adaptation due to its responsibility in physical planning. READ MORE
