  1. 1. Sustainable food packaging based on polyhydroxyalkanoate

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Safana Al-Ashor; [2024]
    Nyckelord :Biopolymers; Sustainable food packaging; Circular economy; Biobased and biodegradable materials; Food packaging; Processing technologies; Food quality; Shelf-life;

    Sammanfattning : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. LÄS MER

  3. 2. The road to an accurate cost estimation in engineer-to-order manufacturing - A case study of cost estimation accuracy within advanced technology development in a defence and security company

    Master-uppsats, Göteborgs universitet/Graduate School

    Författare :Lawin Anwar; Sandra Barría Colliander; [2023-07-03]
    Nyckelord :Engineer-to-order; new product development; cost management; cost engineering; cost estimation error; cost overruns; cost estimation accuracy; project management;

    Sammanfattning : Estimating the costs of a project is a vital part of manufacturing organisations as estimations are what set the basis for the price of the products. Precise estimates allow for effective planning and resource allocation, ensuring that the necessary materials, equipment, and personnel are available to complete the project on time and within budget.

  4. 3. Synthesis of Organo-Iron(II) Complexes Including N-Heterocyclic Carbene Ligation as Solar Cell Material.

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Salim Charkas; [2023]
    Nyckelord :Dye-sensitized solar cell; Transition metal complex; Synthesis iron; N-heterocyclic carbene NHC ; Organic chemistry; Chemistry;

    Sammanfattning : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.

  5. 4. Evaluation of Woodmer/plastic composites

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Leon Ahlström; [2023]
    Nyckelord :Extrusion; Woodmer; Flame test; Tensile test; Composites; Extrudering; Woodmer; Flamtest; Dragtest; Kompositer;

    Sammanfattning : Plast ger otroliga möjligheter i form av stor variation för materialanvändning. Tyvärr sker det dock på bekostnad av miljön då de ackumuleras i naturen. En kompromiss mellan hållbarhet och fortsatt plastanvändning skulle kunna vara att använda biomassa som fyllnadsmaterial i plastkompositer istället för plast. LÄS MER

  7. 5. Synthesis and characterization of lactic acid-based elastomers

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Afsaneh Makhdoumi; [2023]
    Nyckelord :Lactic acid; Elastomer; Bio-based elastomer; Renewable resource;

    Sammanfattning : Synthesized polymer from bio-based and renewable resources reported as an attractive substitution for fossil-fuel based polymers. Therefore, this work has focused on using sustainable material for production of elastomers to reduce the environmental impact of fossil-based elastomers and overcome the shortage of non-renewable fuels.
