    Keywords : ;

    Abstract : High-entropy alloys (HEA) is a class of materials consisting of multiple principal elements that often crystallize in simple lattices such as body-centered cubic, face-centered cubic and hexagonal close-packed structures. Many HEAsexhibit exceptional mechanical properties, e.g. READ MORE

  4. 3. Evaluation of long-term effects of excavated sulfide-bearing rock : - A case study in western Sweden

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Ida Sundblom; [2022]
    Keywords : sulfide-bearing rock; acid rock drainage; sulfide oxidation;

    Abstract : Sulfide-bearing rock that is excavated in conjunction with construction projects can cause environmental and construction engineering problems. Sulfidic minerals oxidize when they are exposed to an oxidant and water, which can make them generate acid rock drainage (ARD) with high concentrations of metals and sulphate. READ MORE

  5. 4. Acid sulphate soils and its influence on metal concentrations in adjacent water bodies. - A case study from Halland, SW Sweden

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Amanda Lindgren; [2021-03-10]
    Keywords : acid sulphate soils; metal distribution; surface water; climate; physicochemistry;

    Abstract : Acid sulphate soils have been referred to as being among the most harmful soils in the world due to their ability to severely decrease the pH of the water, consequently enabling an increased metal load to recipient water streams, lakes, groundwater reservoirs and estuaries. The presence of acid sulphate soils has triggered several fish kill episodes in northern Scandinavia and the soils are today threatening many of the national environmental goals of Sweden. READ MORE
