  1. 1. GRAPHENE MODIFIED E-TEXTILE : AN INDUSTRY RELEVANT APPROACH OF DOPING AND VISUALISING A FULLY TEXTILE P-N JUNCTION DIODES

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Bilel Meskini; [2023]
    Nyckelord :E-textile; viscose; polyester; graphene; graphene oxide GO; reduced graphene oxide rGO; tannic acid; plasma treatment; electrochemical deposition; doping; semiconductor;

    Sammanfattning : As a wonder material, graphene has been studied in various applications due to its exceptional properties. Recently it has been used in textile to obtain functionalised garments as E-textile. From an industry-relevant perspective, it is essential to introduce a process that could be scaled-up. LÄS MER

    Författare :Elina Fernö; [2023]
    Nyckelord :Iron reduction; trace element analysis on magnetite ore; molten salt electrolysis; sodium hydroxide electrolyte; NaOH; greenhouse gas; carbon dioxide; CO2; green ironmaking; Järnreduktion; spårelementanalys på magnetitmalm; smältelektrolys; elektrolys i natriumhydroxid; NaOH; elektrolyt; växthusgas; koldioxid; CO2; grön järnframställning;

    Sammanfattning : This master's thesis covers an investigation of the reduction behavior of different iron oxides when electrolytically reduced with molten salt electrolysis (MSE). The tested iron oxides were wüstite (FeO), hematite (Fe2O3), magnetite (Fe3O4) and magnetite ore concentrate from the Tapuli deposit in Pajala, Norrbotten, Sweden. LÄS MER

  4. 3. 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

  7. 5. 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.
