  1. 1. Fluoride removal by low-cost adsorbents

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Fredrik Bernheim; [2022]
    Keywords : Fluoride; calcium; adsorption; surface precipitation; pH; AOD-slag; ion chromatography; MP-AES; isotherms; Langmuir; Freundlich; Sips.;

    Abstract : Fluoride, the most abundant form of fluorine, is an ion released into the environment, mainly via anthropogenic sources and erosion of mineral rocks. Although the element is well known for its health benefits on teeth and bones, it can as well be a harmful pollutant. READ MORE

  3. 2. CARVING STEEL

    University essay from Göteborgs universitet/Steneby - Institutionen för Konsthantverk och Design

    Author : Arttu Halkosaari; [2020-09-25]
    Keywords : Forging; Tactility; Touch; Plasma cutting; Blacksmith; Texture; Contrast;

    Abstract : This exam project will be a conclusion for a long working process which started a year and a half ago. During this time, I have developed my own way of working with a plasma cutter and use that with different forged forms to create sculptures with varying textures. READ MORE

  4. 3. The Production of Samarium-Cobalt Nanoparticles Using a Spark Discharge Generator

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

    Author : Timothy Lewis; [2019]
    Keywords : Physics and Astronomy;

    Abstract : In this project I attempt to press custom electrodes from Sm and Co powder using two different pressing tools. I investigate if custom electrodes can generate nanoparticles with tailored properties using a spark discharge generator (SDG). READ MORE

  5. 4. Dephosphorisation of Acidic Wastewater : Aimed to allow the recirculation of byproducts as slag builders

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Henrik Welander; Martin Palm; [2018]
    Keywords : Phosphorus removal; Use of Polonite®; Sustainable Metallurgy; Recycling; Neutralization of Wastewater.; Fosforrening; Användning av Polonite®; Hållbar Metallurgi; Återvinning; Neutralisering av Avfallsvatten.;

    Abstract : This study was conducted to evaluate if Polonite® could remove Phosphorus from Sandvik’s wastewater that naturally forms during steelmaking, and hence be proficiently used as a precursor of the neutralization process of said steel plant. Currently lime (CaO) is mixed with the wastewater which creates clean water and sediments, that later need to be landfilled. READ MORE

  6. 5. Surface Treatment of Softwood Lignin Based Carbon Fibers for Enhanced Interfacial Adhesion : Effects of Plasma Treatment Parameters on the Creation of Surface Groups

    University essay from Luleå tekniska universitet/Materialvetenskap

    Author : Yunus Gorur; [2017]
    Keywords : Lignin; adhesion; surface; carbon; fiber;

    Abstract : Lightweight design is an essential part of lowering CO2 emission, which is one of the mostimportant challenges that the automotive industry is facing today. Carbon fiber reinforcedplastics offer an enormous potential for replacing heavier structural materials like steel andaluminum, however due to their high cost and scarcity, carbon fibers are not a very feasibleoption to use in high volume production applications.
