1. 26. Long-Term Impact of Drought on AcidSulfate Soil Leaching, a Study of NineCatchment Areas in Sweden and Finland

   University essay from Uppsala universitet/Luft-, vatten- och landskapslära

   Author : Emilie Åström; [2022]
   Keywords : acid sulfate soil; hydrological drought; water chemistry; metal leaching; sulfate concentration; sur sulfatjord; hydrologisk torka; vattenkemi; metallurlakning; sulfatkoncentration;

   Abstract : Sediments rich in sulfide were deposited in the Littorina sea in an environment that was shallow, anoxic,and reductive. The sediments were brought above sea level by isostatic uplift and can now be foundalong the coast of the Baltic sea. READ MORE

3. 27. Template-assisted Electrodeposition and Model Electrodes Studied by Electron Microscopy and High Energy X-ray Diffraction

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Hanna Sjö; [2022]
   Keywords : Physics and Astronomy;

   Abstract : There is a great interest in studying detailed changes at electrode surfaces during electrochemical processes to better understand the electrochemical reactions at the electrode surface-liquid interface and improve the electrode efficiency. The Au(110) surface has a known (1$\times$2) missing row reconstruction in vacuum conditions, which can change into higher-order (1$\times$3), (1$\times$5), and (1$\times$7) depending on environment.

4. 28. Critical elements scavenged by secondary gypsum and HFO : Determined by sequential extraction combined with mineralogical studies

   University essay from Luleå tekniska universitet/Geovetenskap och miljöteknik

   Author : Emma Flodin; [2022]
   Keywords : Geochemistry; gypsum; HFO; adsorption; scavenged; critical elements; beryllium; Yxsjöberg; mine waste; Sequential extraction; XRD; SEM-EDS;

   Abstract : The demand for metals is great for the purpose of developing green technologies, and EU has listed 30 metals and minerals that are of critical importance for the maintenance and evolving of today’s society, so called critical materials. However, mining of raw materials generates mine waste which can have adverse effect on human health, ecosystems, and surrounding areas. READ MORE

5. 29. Automatic segmentation of microstructures in metals : A computer vision approach

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Oscar Larsen; [2022]
   Keywords : Image Processing; Computer Vision; Machine Learning; Deep Learning; Metallurgy; Segmentation; Bildbehandling; Datorseende; Maskininlärning; Djupinlärning; Metallurgi; Segmentering;

   Abstract : The microstructures of a metal determine the physical, electrical and chemical properties of the metal, and analysis of microstructures is therefore an important part of materials science. Modern microscopes are capable of generating a lot of high-quality micrographs in a short period of time. READ MORE

6. 30. It's smart, but is it sustainable? A study of circular and social sustainability in smart grids.

   University essay from Lunds universitet/Miljövetenskaplig utbildning

   Author : Emma Brodén; [2022]
   Keywords : Smart grids; smart grid users; circular economy; resource use; social sustainability; sustainability; Earth and Environmental Sciences;

   Abstract : Smart grids are often advertised as more environmentally sustainable compared to their “conventional” counterparts. What is highlighted then is their potential to save energy and integrate more renewables into the grid, thus decreasing CO2-emissions. READ MORE
