  1. 16. Trace element leaching from alum shale fines and red ash from Kvarntorp during a large column test

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Helena Rydfjord; [2022]
    Keywords : Alum shale; Leachate; Trace elements; Kvarntorp;

    Abstract : Fuel shortage during the Second World War led to oil production in Kvarntorp, Kumla during 1942-1966 by pyrolyzing alum shale rich in pyrite, FeS2, and organic material such as kerogen. This production has led to a lot of waste laying deposited out in the open after the mining closed and has had negative environmental impact in the form of ongoing weathering and leaching of acidic water and leaching of trace elements into its surroundings.

  3. 17. Investigation on the Optimization of GaN Etching for FinFET Applications

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Albert Malmros; [2022]
    Keywords : Technology and Engineering;

    Abstract : In the framework of this thesis, the optimization of the etching process of GaN for FinFET applications has been investigated. FinFETs are transistors with a vertical architecture in the shape of fins. These fins are fabricated by etching a pattern into a GaN substrate. The etching is carried out in two steps, a dry etch and a wet etch. READ MORE

  5. 19. Determination of bio-accessible amounts of metal trace elements in baby food using In vitro artificial digestion

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Marcus Andersson; [2022]
    Keywords : Food; toxic metals; children; bio-accumulation; artificial digestion; ICP-MS;

    Abstract : Prefabricated baby food is under strict EU legislation by Commission Regulation (EC) 1881/2006 Setting maximum levels for certain contaminants in foodstuffs regarding the maximum allowed content of potentially harmful elements. For potentially toxic trace elements the regulated maximum content is regulated for lead, cadmium, mercury, inorganic tin, inorganic arsenic, cesium, copper and manganese. READ MORE

  6. 20. Record of the end-Triassic mass extinction in shallow marine carbonates: the Lorüns section (Austria)

    University essay from Lunds universitet/Geologiska institutionen

    Author : Linus Brakebusch; [2022]
    Keywords : sedimentology; geochemistry; ooids; oolites; oncoids; oncolites; Triassic; Jurassic; Rhaetian; Hettangian; ocean acidification; Earth and Environmental Sciences;

    Abstract : The end-Triassic mass extinction (ETE) was one of the five big mass extinctions of the Phanerozoic and occurred ~201 Ma ago. Research agrees that the main triggering factor for the ETE was the eruptions of the Central Atlantic Magmatic Volcanic Province (CAMP), linked to the break-up of the supercontinent Pangaea. READ MORE
