  1. 1. SINGLE AND COMBINED EXPOSURE OF POLYSTYRENE NANOPARTICLES AND NORTH SEA MARINE OIL IN TWO IN VITRO FISH MODELS

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Monica Olsson; [2022-10-05]
    Keywords : Polystyrene nanoparticles; crude oil; combined toxicity; cytotoxicity; oxidative stress;

    Abstract : The awareness of micro-and nanoplastic pollution and its impact on the marine ecosystem has increased over the last decade. Nanoplastics may affect aquatic organisms since their small size and high surface-to-volume ratio increases their bioavailability and ability to cross biological membranes. READ MORE

  3. 2. Characterization of PLA Nanoplastics, and Their Effects on Daphnia magna

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Melinda Rydberg; [2022]
    Keywords : Polylactic acid; Polylactide; PLA; Nanoplastic; Daphnia magna; Toxicity; Polymer Technology; Chemistry; Earth and Environmental Sciences;

    Abstract : As plastic pollution in aquatic environments keeps happening it has become more and more important to learn more about nanoparticles. Bio-based and biologically degradable plastics, such as polylactic acid (PLA), are gaining popularity and it is therefore important to determine whether they break down into nanoplastics or not.

  4. 3. Characterization of Magneto-Dielectric Materials for Microwave Devices

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Joseph Lazraq Byström; [2020]
    Keywords : magneto-dielectric materials; permittivity; permeability; losses; antenna and filter miniaturization;

    Abstract : There is an increasing interest in using new composite materials in microwave devices, to reduce size and weight while maintaining similar performances. A new promising material group is named magneto-dielectric materials, which have the permittivity and permeability values both larger than one. READ MORE

  5. 4. Combination of nanoparticles from polystyrene and the hormone 17alpha-ethinylestradiol (EE2) in water.

    University essay from Lunds universitet/Miljövetenskaplig utbildning

    Author : Emma Nilsson; [2017]
    Keywords : water; nanoparticles; hormons; Plastic; Earth and Environmental Sciences;

    Abstract : Plastic materials and synthetic hormones are found in aquatic environments globally. Plastic in water can degrade to nanoparticles (NP) with special characteristics, in the environment nanoparticles and hormones have a proven effect on wildlife. READ MORE

  6. 5. Polystyrene nanoparticles interactions with Calbindin D9k and Monellin

    University essay from Lunds universitet/Examensarbeten i molekylärbiologi

    Author : Martin Lindunger; [2017]
    Keywords : Biology and Life Sciences;

    Abstract : Nanomedicine and the use of nanoparticles (NPs) are growing like never before. It is therefore important to investigate the interactions in the nano world and the possible hazards. Proteins in organisms can adsorb to NPs and change the proteins structure and therefore their functions. READ MORE
