  1. 1. Investigating Brønsted Acidic Deep Eutectic Solvents for Recycling of Lithium Cobalt Oxide

    University essay from Uppsala universitet/Strukturkemi

    Author : Mattias Lindgren; [2022]
    Keywords : Deep eutectic solvents; Recycling; Lithium-Ion Batteries; Cathode Materials; LCO;

    Abstract : Recently, the production of lithium-ion batteries (LIB) has grown rapidly, highlighting the need for efficient and environmentally friendly recycling of LIB waste. In this work, the usage of so-called deep eutectic solvents (DESs) for the leaching of the LIB cathode material lithium cobaltoxide is investigated. READ MORE

  3. 2. Recycling of Textile and Plastic from an Interior Vehicle Component

    University essay from KTH/Fiber- och polymerteknologi

    Author : Esther Wennerstrand; [2021]
    Keywords : Polycarbonate; ABS; poly ethylene terephthalate ; mechanical recycling; chemical recycling; Polykarbonat; ABS; polyetylentereftalat; mekanisk återvinning; kemisk återvinning;

    Abstract : På grund av den rådande klimatförändringen och de globala problem som plast orsakar i miljön blir det allt viktigare att dagens linjära materialanvändning ändras till en cirkulär användning. Inom fordonsindustrin har kravet på ökad tillgänglighet och kvalitet på återvunna material identifierats. READ MORE

  4. 3. Acoustic trapping of sub-micrometreparticles within microfluidics particles within microfluidics

    University essay from Uppsala universitet/Mikrosystemteknik; Uppsala universitet/Polymerkemi

    Author : Björn Stenestam; [2021]
    Keywords : ;

    Abstract : The aim of this project was to prove that a pre-existing standardmethod for bacterial-DNA extraction can be reduced down to the microscale and in doing so be used in an on-chip setting.The first phase in this project was to identify an appropriate methodand material for droplet generation.

  5. 4. Negative energy elasticity and a model for the behavior of the residual strain in doubly cross-linked gels fabricated by shear strain

    University essay from Uppsala universitet/Polymerkemi

    Author : Therese You; [2020]
    Keywords : Polymer gel; Tetra-PEG; hydrogels; doubly cross-linked gels; shear modulus; energy elasticity;

    Abstract : Doubly cross-linked gels were fabricated based on tetra-poly(ethylene glycol) (Tetra-PEG) by shear strain. These are gels with two network structures present in the same polymeric network. The second network structure is introduced by applying a mechanical field to the first natural network structure.

  6. 5. Design of telechelic oligo-(caprolactone-co-dioxanone) as photocurable macromonomers for degradable gels

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Tran Tam Nguyen; [2020]
    Keywords : macromonomers; ring-opening co-oligomerization; telechelic co-oligomers; polymer; organocatalyst; makromonomerer; ringöppning samoligomerisering; telekelisk samoligomer; organisk katalysator;

    Abstract : Three-dimensional (3D) printing has an important role for fabrication of degradable scaffoldsfor soft tissue regeneration. Among the 3D printing techniques, photopolymerization-based 3Dprinting is one of fastest growing, offering environmental benefits and high precision of 3Dobjects. READ MORE
