  1. 1. Machined surfaces as designed cell culture substrates

    University essay from Lunds universitet/Industriell Produktion

    Author : Kunal Sharma; [2021]
    Keywords : Surface topography; cell proliferation; cell adhesion; Technology and Engineering;

    Abstract : De flesta levande celler fäster på ytor av olika slag för att kunna växa, men vilka faktorer som bidrar till deras infästning på metallytor är hittills okänt. Man vet att ytans ojämnhet spelar en roll och att vissa material är cytotoxiska. READ MORE

  2. 2. Boiling heat transfer of multiple impinging water jets on a hot rotary cylinder

    University essay from Högskolan i Gävle/Avdelningen för byggnadsteknik, energisystem och miljövetenskap

    Author : Aitor Uriarte; [2021]
    Keywords : Quenching; unsteady heat transfer; multiple impinging jet; boiling; rotary cylinder; fast cooling.;

    Abstract : Quenching technique is widely used in industrial applications as it enhances the mechanical properties of metals such as hardness and tensile strength. This technique consists of a heating process followed by fast cooling which results in different microstructures that enhance the metal behavior. READ MORE

  3. 3. Separation of Cobalt and Nickel using CYANEX 272 for Solvent Extraction

    University essay from KTH/Kemiteknik

    Author : Caroline Kihlbom; [2021]
    Keywords : Solvent extraction; cobalt-nickel separation; CYANEX 272; pregnant leach solution; cobalt sulphate; Vätskevätskeextraktion; kobolt-nickel separation; CYANEX 272; laklösning; koboltsulfa;

    Abstract : This project aimed to examine the separation of cobalt and nickel using solvent extraction (SX) with the extractant CYANEX 272 (C272). It was intended to investigate the Co-Ni separation in a sulphate-based leach solution in presence of other contaminants. READ MORE

  4. 4. Evaluation of a gross pollutant trap-biofilter stormwater treatment train : The Role Of Calcium Carbonate, Vegetation And Pre-Treatment Facility

    University essay from Luleå tekniska universitet/Arkitektur och vatten

    Author : Sofia Fahlbeck Carlsson; [2021]
    Keywords : Bioretention; stormwater; stormwater treatment; stormwater pollutants; heavy metals; phosphorus; Biofilter; dagvatten; dagvattenrening; dagvattenföroreningar; tungmetaller; fosfor;

    Abstract : Development of cities, new buildings and other impervious surfaces entails increased stormwater flows, volumes and pollutant loads. Heavy metals, nutrients, sediments and salt are common pollutants in stormwater. READ MORE

  5. 5. Cobalt and nickel concentrations in the Uppsala clay deposits : solubility and risk assessment

    University essay from SLU/Dept. of Soil and Environment

    Author : Ali Reza Sadeghi; [2020]
    Keywords : heavy metals; soil contanimation; geochemically active fraction; leaching test; guideline value; site-specific guideline value;

    Abstract : Heavy metals create a contamination problem in soils. Examples of heavy metals are Ni, Co, and Cu. Soil environment and minerals existing in the soil such as Fe and Mn oxides affect the presence of these heavy metals. In this thesis, the cobalt and nickel concentrations of selected soil samples from different locations in Uppsala were determined. READ MORE
