  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

  3. 2. Changes in lake-water organic carbon over recent centuries in northern Sweden, Västerbotten : Past and present mechanisms, and the potential implications on mercury

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Magnusson Petter; [2023]
    Nyckelord :Lake-water TOC; Summer forest farming; traditional agriculture; land-use; geochemistry; mercury;

    Sammanfattning : Due to the current increase in lake water total organic carbon (LW-TOC), many studies have investigated the long-term dynamics using lake sediments. However, these have mainly been focused on Sweden’s south and south-central parts. LÄS MER

  4. 3. Kalknings påverkan och brunifiering av ytvatten i Västra Götalands län, Sverige : Drivande faktorer och trender

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Hanna Andersson; [2023]
    Nyckelord :Brownification; Surface waters; Acid deposition; Liming;

    Sammanfattning : For more than 45 years an extensive liming measure has taken place in the southwest of Sweden in Västra Götaland county. The goal with the liming is to improve the aquatic ecosystems and counteract the acidification that has occurred in a large part of catchments in this area. LÄS MER

  5. 4. Effect of infill density on mechanical and fire properties of polylactic acid composites produced by FDM 3D-printing technology

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :David Aronsson Edström; Oskar Lundberg; [2022]
    Nyckelord :3D-printing; FDM; PLA; fire; fire engineering; cone calorimeter; tensile test; UL-94;

    Sammanfattning : 3D-printing is a new and upcoming manufacturing technique that can significantly reduce time and material losses in production. Fused deposition modeling (FDM) is one of the most commonly used 3D-printing methods for processing conventional thermoplastic polymers. LÄS MER

  7. 5. 3D printer in dosimetry and mammography – designing and testing an OSL dosemeter holder and a low contrast-detail phantom

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Måns Boll; [2022]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Introduction: Today, 3D printing is a versatile tool used in a wide range of fields. With the advent of more cost-effective fused deposition modelling (FDM) 3D printing technologies it is time to investi- gate what such a 3D printer has to offer in radiation science applications.
