  1. 11. A Comparative Life Cycle Assessment of Alternative Polymers to Poly(vinyl chloride) for Use in Flooring Applications

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Caroline Almqvist; Pernilla Larsson; [2021]
    Keywords : PVC; Flooring; Life Cycle Assessment; LCA; Polymer technology; Earth and Environmental Sciences; Chemistry; Technology and Engineering;

    Abstract : Poly(vinyl chloride) has a long history of use in the flooring industry. Throughout the years, several environmental and health issues have arisen concerning the production, usage and disposal of PVC. READ MORE

  3. 12. The effects of pH and biodegradation on polymer-based granules

    University essay from Lunds universitet/Bioteknik (master)

    Author : Isak Svenningsson; [2021]
    Keywords : polymerteknik; biopolymer; bioteknik; Technology and Engineering; Biology and Life Sciences; Chemistry;

    Abstract : The use of biopolymers instead of traditional fossil fuel based and non-biodegradable polymers is seen as a positive step forward towards a more environmentally friendly future. This project investigates a granule product that is used in a dishwashing system with the aim of gaining knowledge about how it is affected by the storage in between uses and its biodegradability.

  4. 13. Electrical wiring of Shewanella oneidensis MR-1 with osmium polymers of different redox potentials

    University essay from Lunds universitet/Kemiska institutionen; Lunds universitet/Beräkningskemi

    Author : Laleh Tavakoli; [2021]
    Keywords : Analytical Chemistry; Bio-Analytical Chemistry; Electrochemistry; Bacteria; Osmium redox polymers; Shewanella Oneidensis MR-1; electrode; Microbial electrosynthesis; Electron transfer; Chemistry;

    Abstract : The results of studies have shown that the several applications such as microbial electrochemical system (MES), bio-electrochemical systems (BESs) and production of beneficial chemicals are due to electrochemical connection among electrodes and microorganisms. The following two factors are important in choosing the microbe mediated electrochemical biosensors: I) Binding of bacterial cells on the electrode, II) Efficient electron transfer (EET) between the electrode and the cells by a mediator.

  5. 14. Structural Battery Electrolytes

    University essay from KTH/Fiber- och polymerteknologi

    Author : Pernilla Öberg; Amanda Halvarsson; Julia Rune; Max Bjerkensjö; [2021]
    Keywords : structural battery electrolytes; polymerization-induced phase separation; bicontinuous morphology; lithium-ion conductivity; thiol-ene chemistry; Strukturella batteri-elektrolyter; polymerisations-inducerad fasseparation; bikontinuerlig morfologi; litium-jon konduktivitet; tiol-en kemi;

    Abstract : Strukturella batterier är multifunktionella; de tillhandahåller lagring av elektrokemisk energi samtidigt som de bidrar med en lastbärande funktion. Tillsammans möjliggör detta att batteriet kan integreras i karossen hos ett elektriskt fordon eller apparat. READ MORE

  6. 15. Poly(p-terphenyl piperidinium) as anion exchange membranes. Synthesis and evaluation of properties

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Hugo Selling; [2020]
    Keywords : Fuel cells; Alkaline exchange membrane fuel cells; Anion exchange membrane fuel cells; Polymer technology; Polymerteknologi; Chemistry; Technology and Engineering;

    Abstract : Alkaline exchange membrane fuel cells (AEMFC) is an interesting and attractive alternative to proton exchange membrane fuel cells (PEMFC) due to the potential use of non-precious catalysts which can reduce the overall cost of the fuel cell. An important component of the AEMFC is the anion conducting membrane. READ MORE
