  1. 1. Sustainable Recycling of Electrolytes for Vanadium Redox Flow Batteries : Method development and Review (Bachelor Thesis)

    Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Reza Doulati; [2023]
    Nyckelord :vanadium redox flow batteries VRFB; eco-friendly recycling; precipitation of vanadium; vanadium oxides; Energy storage system; ESS; circular economy; sustainable recycling method;

    Sammanfattning : Vanadium Redox Flow Batteries VRFBs are promising energy storage systems with highly recyclable electrolytes. The recycling of these systems usually involves ammonium-based salt precipitation steps, which produce toxicgases and contaminated water as waste. LÄS MER

  3. 2. Analysis of Methanol Based Chlorine Dioxide Production : An analysis of sodium chlorate reduction efficiency and investigation of salt cake filter wash on an SVP-LITE® system

    Kandidat-uppsats, Karlstads universitet

    Författare :Emil Lundh; [2023]
    Nyckelord :ECF; SVP-LITE®; chlorine dioxide; bleaching; ECF; SVP-LITE®; Klordioxid; blekning;

    Sammanfattning : This work aimed to determine how effective an SVP-LITE® chlorine dioxide plant at Vallviks Bruk was running. This was done by determining the chemical consumption per unit of chlorine dioxide produced. The calculations relied upon online instrumentation that was manually validated. LÄS MER

  4. 3. Recycling end-of-life silicon PV panel with molten salt bath

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Liying Yu; [2023]
    Nyckelord :;

    Sammanfattning : Solar energy is recognized as a clean way to produce electricity. Solar PV's installed capacity is increasing in recent years. However, a PV panel has a 25-year lifespan on average. In actuality, 95% of the mass of PV components can be recycled. LÄS MER

  5. 4. Optimization of two high-performance size-exclusion chromatography methods with diode-array detection for protein quantification and purity assessment

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Camilla Lane; [2023]
    Nyckelord :Method qualification; Protein concentration; Protein Purity; High Performance Size exclusion chromatography; Quality control; Analytical chemistry; Biology and Life Sciences;

    Sammanfattning : Background: There is a need to develop methods of determining concentration and purity for two new affinity ligands, protein T and protein H, in order to ensure the quality of an industrial production of said proteins. Aims: To develop a High Performance Size Exclusion Chromatography, HPSEC, method to determine concentration and purity of protein T and to improve an existing HPSEC method for concentration and purity determination of protein H that show selectivity, display linearity between peak area and injection amount and give repeatable results.

    Kandidat-uppsats, Örebro universitet/Institutionen för beteende-, social- och rättsvetenskap

    Författare :Carolina Andersson; Ella Pålbrant; [2023]
    Nyckelord :“lilla hjärtat”; “lex lilla hjärtat”; Care of Young Persons Act; best interest of the child; child’s perspective; Lilla hjärtat; lex lilla hjärtat; LVU; barnets bästa; barnets perspektiv;

    Sammanfattning : Esmeralda, som även kom att kallas ”lilla hjärtat”, påträffades avliden hos sina biologiskaföräldrar kort efter att vården av henne enligt LVU upphörde. Som ett resultat av Esmeraldastragiska öde presenterades reformen lex lilla hjärtat, vilken resulterade i flertal lagändringarsom trädde i kraft den 1 juli 2022. LÄS MER
