  1. 26. Automation of carbonyl index calculations for fast evaluation of microplastics degradation

    University essay from KTH/Fysik

    Author : Maja Walfridson; Emma Kuttainen Thyni; [2022]
    Keywords : FTIR; Carbonyl index; Degradation of microplastics; Microplastics; Automation;

    Abstract : The broad use of plastics has resulted in the increase in both production and consequent plastic pollution in the environment. Microplastics, defined as particles < 5 mm, is of special interest because of its wide existence in environment and potential hazards to our ecosystem. READ MORE

  3. 27. 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. 28. Large Surface Area of Graphene with Controlled Interlayer Spacing

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

    Author : Hari Hara Sudhan Thangavelu; [2022]
    Keywords : pillared graphene; porous structure; energy storage; interlayer galleries.; pelargrafen; porös struktur; energilagring; mellanskiktsgallerier.;

    Abstract : Unique layered structure with excellent electrical, mechanical, thermal, and optical properties gives graphene widespread application. Graphene based materials are extensively studied in the field of energy storage such as batteries, hydrogen storage and supercapacitors (SC’s). READ MORE

  5. 29. Investigation of stability in high salt polymer electrolytes for sodium batteries

    University essay from Uppsala universitet/Strukturkemi

    Author : Fengnan Yuan; [2022]
    Keywords : ;

    Abstract : Poly(trimethylene carbonate)–sodium bis(fluorosulfonyl)imide system shows a promising performance as polymer-in-salt electrolytes. The polymer electrolytes with salts concentration from 62% to 71% were tested through DSC, FTIR, EIS and constant current cycling. The solubility of the salts varies in different salts in PTMC.

  6. 30. DELAMINATING PAINT IN AN 18TH CENTURY CANVAS WALL PAINTING A Case Study at the von Echstedt Manor

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Lisa Bandgren; [2021-10-28]
    Keywords : Delaminating Paint; Canvas Wall Paintings; Material Analysis;

    Abstract : This study investigates the cause and progression of the ongoing deterioration in a canvas wall painting from the 1760s in the Green Chamber at the von Echstedt manor. In an area approximately 170 x 170 cm on the south wall, the paint is severely delaminating despite several attempt to consolidate it. READ MORE
