  1. 1. 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.

  3. 2. Reprocessing weather data from Smart Stake weather stations on the Greenland ice sheet

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Leon Lovén; [2023]
    Keywords : ice sheet; data processing; weather station; Greenland; GEUS; Smart Stake; istäcke; databehandling; väderstation; Grönland; GEUS;

    Abstract : To identify a climate trend, a lot of data is required for the conclusion to be accurate. A trend can require 30 years worth of measurements in order to say anything with certainty about how the climate is changing. It is therefore important to utilize every source of data in climate research. READ MORE

  4. 3. Subtree Hashing of Tests in Build Systems : Rust Tricorder

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Abstract : Software applications are built by teams of developers that constantly iterate over the codebase. Software projects rely on a build system, which handles the management of dependencies, compilation, testing, and deployment of the software. READ MORE

  5. 4. MDR’s Impact on Standards Usages and the Relevance for In-house Production of Medical Devices

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Alexander Söderberg; Birante Soumare; [2022]
    Keywords : In-house production; MDR; Reprocessing; 3D-printing; Swedish Institute for Standards; Standards; Egentillverkning; MDR; Reprocessing; 3D-printing; Svenska Institutet för Standarder; Standarder;

    Abstract : The current regulation for Medical Devices (MDR) entered into force on 26 May 2021, which has entailed major changes to relevant legislation for in-house production of medical devices in healthcare. The relevance for updating existing, or the development of new standards is currently not well documented and determined and the aim of this report is to make recommendations for how the development of standards may be improved and how departments of medical technology (DMT) in practice apply standards at in-house production of medical devices.

  6. 5. Reprocessing of Marine Reflection Seismic Data from Skåne, Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Charlotta Carlsson; [2022]
    Keywords : Reflection seismics; marine geophysics; Claritas; Claritas; reflektionsseismik; geofysik;

    Abstract : During 1979, an oil prospecting project was initiated in the south of Sweden, outside the coast of the municipality of Skåne. No drilling program was initiated, and the project was put on ice. However, with the oil prices of today and the interest in carbon dioxide storage, the area could once again be interesting. READ MORE
