  1. 31. Optimization of Rare Earth Metals (REM) addition in high temperature stainless steel grade 253MA.

    University essay from KTH/Materialvetenskap

    Author : Bharath Vasudev Rangavittal; [2019]
    Keywords : REM addition; non-metallic inclusion; oxidation; austenitic; optimization;

    Abstract : The focus of this thesis work is to optimize rare earth metal (REM) addition in Therma 253MA, an austenitic stainless-steel grade in order to get a good trade-off between oxidation resistance property and the amount of big REM inclusions formed. Big REM inclusions are detrimental to material properties and REM is required to be dissolved in the matrix for improving the oxidation resistance. READ MORE

    Abstract : Many new models of smartphones and small electronic devices are using their wireless charging feature as a key selling point. This is due to the convenience of cable-free charging as well as not requiring multiple power adapters for charging different devices. READ MORE

  4. 33. Mouthpart deformities of Chironomid larvae as an indicator of heavy metal polluted water

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Tim Lindström Jonsson; [2019]
    Keywords : Chironomidae larvae; Deformities; Heavy metals; Biomonitoring; Mining; Northern Sweden;

    Abstract : Freshwater ecosystems are under increasing pressure from a variety of contaminants, including heavy metals from mining operations, which can have complex effects that are difficult to evaluate. To detect early warnings from elevated concentrations of metals, organisms are sought to be used as monitoring tools. READ MORE

  5. 34. Long-term application of digestate and biofuel ash to arable soil : effects on the solubility of Cd, Al and trace metals as evidenced by simulated scenarios

    University essay from SLU/Dept. of Soil and Environment

    Author : Elias Bäckström; [2018]
    Keywords : cadmium; fertilizer; Visual MINTEQ;

    Abstract : The importance of nutrient recycling could not be emphasized enough in to-day’s society. Reduction of waste as well as recycling of nutrients would be the result if ash and biogas digestate could be used as fertilizer. However, the solubility of Cd, Al and micronutrients might be affected in a different way than by standard fertilizers. READ MORE

  6. 35. Analysing toxicity for biochemical-producing organisms

    University essay from KTH/Hållbarhet och miljöteknik

    Author : Raül López i Losada; [2018]
    Keywords : ;

    Abstract : Using macroalgae as bio-feedstock for the bio-based plastic industry is a developing process that possesses inherent comparative advantages with regard to its environmental impacts compared to using other bio-feedstock sources. Thus, research effort is considered necessary to improve its competitiveness and resolve the technical challenges that it is currently facing. READ MORE
