  1. 11. Measuring the [C II]-to-H I connection in high-redshift absorption-selected galaxies

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Gaurav Senthil Kumar; [2022]
    Keywords : QSO; Quasar; Black Hole; AGN; Active Galactic Nuclei; DLA; Damped Lyman Alpha; C II; [C II]; H I; Sightline; HST; X-shooter; Spectroscopy; Echelle Spectroscope; Hyperfine transition; Hyperfine; Physics and Astronomy;

    Abstract : HI neutral gas is the basic building block of galaxies. It dictates the star formation rate and hence the metal enrichment rates within high redshift galaxies. HI neutral gas cannot be directly observed beyond z ≈ 0. READ MORE

  3. 12. Influence of mass transport on glycerol electrooxidation on palladium in alkaline media

    University essay from KTH/Tillämpad elektrokemi

    Author : Elvira Lind; [2022]
    Keywords : Glycerol electrooxidation; Palladium; Mass transport; Comsol Multiphysics; Rotating disk electrode; Electrooxidation av glycerol; Palladium; Masstransport; Comsol Multiphysics; Roterande diskelektrod;

    Abstract : Vid produktion av biodiesel produceras även råglycerol (10 vikt%) som biprodukt och utbudet av råglycerol har ökat över de senaste åren till följd av att biodieselproduktionen ökat. Marknadsvärdet för råglycerol är lågt, men det är en utmärkt föregångare till att producera mervärdesprodukter för exempelvis läkemedelsindustrin, kemikalieindustrin eller kosmetika. READ MORE

  4. 13. The Transition Towards Hydrogen as a Sustainable Fuel : Exploring the Organizational Field of Hydrogen Mobility in Sweden

    University essay from Umeå universitet/Företagsekonomi

    Author : Viktor Fabricio de Barros; William Sandberg; [2021]
    Keywords : Hydrogen; mobility; logistics; fuel cell; sustainability; transition; organizational field; institutionalization; Vätgas; transport; logistik; bränslecell; hållbarhet; övergång;

    Abstract : The overall goal with this master’s thesis is to describe the institutionalization process of the organizational field of Hydrogen Refuelling Stations (HRS) with green hydrogen produced via electrolysis for the heavy-duty truck sector in Sweden. Hydrogen mobility is a recent technology, which makes its organizational field formation and development processes interesting to examine. READ MORE

  5. 14. Fluorine-free electrolytes for Li-ion batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Filippa Wahlfort; [2021]
    Keywords : Li-ion batteries; fluorine-free;

    Abstract : Lithium-ion batteries are of great importance for today's society. The state-of-the-art batteries that are used today use a fluorinated electrolyte that contains the salt LiPF6 and acts as both a safety hazard and an environmental issue due to its ability to form the toxic gas hydrogen fluoride (HF).

  6. 15. Determining the Influence of the Type of Shielding Gas during Additive Manufacturing of an Aluminum Alloy by Monitoring the Process Qualitatively and Analyzing Process Byproducts Quantitatively

    University essay from KTH/Materialvetenskap

    Author : Stefanie Desiree Kleemeyer; [2021]
    Keywords : additive manufacturing; PBF-LB M; aluminum; shielding gas; argon; nitrogen; helium; carbon dioxide;

    Abstract : This thesis analyzes the influence of process gases on the formation and the characteristics of process byproducts that emerge during additive manufacturing of an aluminum alloy belonging to the 2000 series.  In order to address the influence, four pure gases, argon, nitrogen, helium, and carbon dioxide, were used as a shielding gas on the same parameter sets.
