Accelerated hydrolysis method for producing partially degraded polyester microplastic fiber reference materials
Sarno, Antonio; Olafsen, Kjell; Kubowicz, Stephan; Karimov, Fuad; Sait, Shannen; Sørensen, Lisbet; Booth, Andy (Peer reviewed; Journal article, 2020)Microplastic fibers (MPFs) from textiles significantly contribute to the microplastic (MP) load in many environmental matrices and have been shown to negatively impact the organisms therein. Most fate and effect studies ... -
Copper enrichment on aluminium surfaces after electropolishing and its effect on electron imaging and diffraction
Wenner, Sigurd; Lervik, Adrian; Thronsen, Elisabeth; Marioara, Calin Daniel; Kubowicz, Stephan; Holmestad, Randi (Peer reviewed; Journal article, 2021)Electropolishing is the most common method of preparing samples of aluminium alloys for scanning and transmission electron microscopy, as it yields a good surface quality and large flat, electron-transparent areas. Like ... -
Effect of Cu2+ on deposition mechanism and structure of ZrO2-based conversion coatings on AA6060 aluminium alloys and their susceptibility to filiform corrosion
Mysliu, Erlind; Storli, Kathrine Sletteberg; Skogøy, Hanna Marie; Kubowicz, Stephan; Svenum, Ingeborg-Helene; Lunder, Otto; Erbe, Andreas (Peer reviewed; Journal article, 2024)Zirconium oxide-based conversion coatings (CCs) were prepared from hexafluorozirconic acid, H2ZrF6, with and without CuII as an additive. The CCs were prepared on primary and recycled AA6060. The deposition mechanism, ... -
Microplastic fibres from synthetic textiles: Environmental degradation and additive chemical content
Sait, Shannen; Sørensen, Lisbet; Kubowicz, Stephan; Vike-Jonas, Kristine; Gonzales, Susana Villa; Asimakopoulos, Alexandros; Booth, Andy (Peer reviewed; Journal article, 2021)Microplastic fibres (MPFs) often make up the largest fraction of microplastic pollution in aquatic environments, yet little is known about their degradative fate and persistence. This study investigates the environmentally ... -
Nanoparticle-stabilized microbubbles for multimodal imaging and drug delivery
Mørch, Ýrr Asbjørg; Hansen, Rune; Berg, Sigrid; Åslund, Andreas; Glomm, Wilhelm; Eggen, Siv; Schmid, Ruth; Johnsen, Heidi; Kubowicz, Stephan; Snipstad, Sofie; Sulheim, Einar; Hak, Sjoerd; Singh, Gurvinder; McDonagh, Birgitte Hjelmeland; Blom, Hans; Davies, Ruth Catharina de Lange; Stenstad, Per Martin (Journal article, 2015)Microbubbles (MBs) are routinely used as contrast agents for ultrasound imaging. The use of ultrasound in combination with MBs has also attracted attention as a method to enhance drug delivery. We have developed a technology ... -
