  1. 6. Development of a microfluidic device to study simultaneous crystallization in the LIBs recycling process

    University essay from KTH/Kemiteknik

    Author : Shefali Paresh Solanki; [2023]
    Keywords : Battery recycling; microfluidics; simultaneous crystallization; simulation; crystal technology; microfluidics experimental setup; Batteriåtervinning; mikrofluidik; simultan kristallisering; simulering; kristallteknologi; mikrofluidikexperimentuppställning;

    Abstract : Återvinning av litiumjonbatterier (LIB) är avgörande på grund av kritiska råmaterialreserver och miljöhänsyn vid kassering. Hydrometallurgisk LIB-återvinning, en framstående industriell teknik, står inför kostnadseffektivitets- och komplexitetsutmaningar. READ MORE

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

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

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

    Abstract : 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. READ MORE

  4. 8. Molecular detection of Sclerotinia sclerotiorum from petals of oilseed rape by Nanopore sequencing using MinIon

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Sohunda Abela; [2023]
    Keywords : ;

    Abstract : Sclerotinia sclerotiorum is a plant pathogenic fungus that causes Sclerotinia stem rot in oilseed rape. In Sweden, the disease causes severe crop loss that varies by year. READ MORE

  5. 9. Navigating Large-Scale Plasmid DNA Purification : A Recommendation of Current and Future Downstream Purification Solutions

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Matilda Eriksson; Alva Wells; Maria Frey; Lisa Johansson; Gabriel Pettersson; David Sjöberg; [2023]
    Keywords : Plasmid purification; pDNA; large-scale chromatography;

    Abstract : Previous small-scale methods for plasmid DNA (pDNA) purification fail to meet theindustry’s demand for sufficient quantities. Greater volumes of bacterial lysates are a consequence of larger volumetric fermentations and traditional large-scale down-stream purification processes have some disadvantages and limitations.

  6. 10. Reprocessing and Characterization of Polybenzimidazole for High-Temperature Polymer Electrolyte Membrane Fuel Cells

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Douglas Björkengren; [2023]
    Keywords : polymer electrolyte membrane fuel cells; PEMFC; HTPEMFC; polymer technology; polymer characterization; reprocessing; recycling; polybenzimidazole; PBI; Technology and Engineering;

    Abstract : A reprocessing method of poly(2,2’-(m-phenylene)-5,5’-bibenzimidazole) (PBI) membranes recovered from the production line of High-Temperature Polymer Electrolyte Membrane Fuel Cells (HT-PEMFC) at Blue World Technologies (BWT) has been developed in order to reduce material loss in the production. Redissolution of scrap PBI membranes in poly(phosphoric acid) (PPA) and phosphoric acid (PA) was successful and the subsequent washing procedure produced PBI that could be redissolved in N,N-dimethyl acetamide (DMAc) and suitable for solution casting of new membranes.
