  1. 36. Synthesis and characterization of lactic acid-based elastomers

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

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

    Abstract : 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.

  3. 37. Study on Decolorization of Reactive-dyed Cotton through Fenton-oxidation as a Pre-treatment for Textile Recycling

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Elise Meurs; [2023]
    Keywords : Fenton-oxidation; advanced oxidation processes; decolorization; textile recycling; cotton; reactive dye;

    Abstract : In this master thesis, the feasibility of Fenton-oxidation for the decolorization of reactive dyed cotton is investigated as a potentially environmental-friendly preparatory treatment for mechanical/chemical recycling. Raw, knitted cotton is dyed with a black and a blue dye, whereafter preliminary tests are performed to investigate the influence of increasing Fenton- solution concentrations and different iron-sources on the efficiency of the discoloration, without carrying out complete optimization of the process-parameters.

  4. 38. Size effect in wood : Characterization of mechanical properties using digital image correlation method

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Amir Saeidi; Olafur Johannsson; [2023]
    Keywords : compression test longitudinal direction; digital image corre- lation DIC ; ncorr; phyton; pinewood; size effect; stiffness matrix; wood- construction; YAWCAM; young’s modulus; digital image correlation DIC ; elasticitetsmodul; furu; kom- pressionstest längs fiberriktning; ncorr; phyton; storlekseffekt; styvhetsma- tris; trä-konstruktion; YAWCAM;

    Abstract : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. READ MORE

  5. 39. Synergistic fire- and mechanical effect of biochar and ammonium polyphosphate in epoxy composite

    University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Author : Anton Olausson; Ludvig Jönsson; [2023]
    Keywords : Ammonium polyphosphate; Biochar; Composite; Epoxy; Synergistic effect;

    Abstract : Polymer composites are used in a varying extent and are challenging the use of traditional materials due to the push towards sustainable development. They have replaced steels and aluminum alloys in applications. READ MORE

  6. 40. Theoretical investigation of Co-dependence in magnetic high-entropy alloys

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Johan-Michael Kurak; [2023]
    Keywords : ;

    Abstract : High-entropy alloys (HEA) is a class of materials consisting of multiple principal elements that often crystallize in simple lattices such as body-centered cubic, face-centered cubic and hexagonal close-packed structures. Many HEAsexhibit exceptional mechanical properties, e.g. READ MORE
