  1. 1. Towards a sustainable substitute for Acrylonitrile Butadiene Styrene (ABS) in automotive industry

    University essay from KTH/Fiber- och polymerteknologi

    Author : Amalia Christoula; [2023]
    Keywords : Polylactide PLA ; Biobased; Life Cycle Analysis LCA ; Impact modifiers; Lignocellulose nanofibers LCNF; Polylaktid PLA ; Biobaserad; Livscykelanalys LCA ; Slagtålighet; Nanofibrer av lignocellulosa LCNF ;

    Abstract : Syftet med detta examensarbete var att utveckla ett hållbart ersättningsmaterial till akrylnitrilbutadienstyren plast (ABS), genom att applicera principerna för grön kemi och teknik. ABS är en icke-nedbrytbar plast som till exempel används i slagtåliga produkter för hyttinteriörer. READ MORE

  3. 2. Enhancement of translucence in fiber-based packaging materials

    University essay from KTH/Fiber- och polymerteknologi

    Author : Saila Tallinen; [2022]
    Keywords : Paper; translucent; fiber-based packages; impregnation; cellulose; papper; genomskinlighet; fiberbaserade förpackningsmaterial; impregnering; cellulosa;

    Abstract : The utilization of fiber-based packages has started to take more place at the packaging sector but is still restricted by a lack of transparency. Today this challenge is tried to be solved by paying more attention on the characteristics of nanofibers and their possibilities. READ MORE

  4. 3. Evaluation of electrospun lignin/polyvinyl alcohol/cellulose nanofiber mats

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

    Author : Lisa Johansson Carne; [2021]
    Keywords : Electrospinning; lignin; polyvinyl alcohol; cellulose nanofiber; wound dressing;

    Abstract : Polymeric electrospun nanofiber mats have recently emerged as a promising alternative to conventional wound dressings for non-healing wounds. Its large surface area, porosity and scalability are only a few of the promising characteristics of electrospun nanofibers. READ MORE

  5. 4. Biobased carbon aerogels incorporated with zeolite nanoplates for carbon dioxide adsorption

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

    Author : Maria Harila; [2021]
    Keywords : biobased; carbon aerogel; lignin; cellulose nanofiber; adsorption; carbon dioxide; zeolite nanoplate;

    Abstract : Over the last 100 years there has been an increase of greenhouse gases (CO2, CH4 and N2O) in the atmosphere. These gases cause several problems with the climate on Earth, such as increasing problems with extreme weather. One way to decrease the outlet of carbon dioxide is by adsorption and capture of CO2.

  6. 5. Acoustic Droplet Vaporization : An Assessment of How Ultrasound Wave Parameters Influence the Vaporization Efficiency

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Sara Öquist; [2020]
    Keywords : Acoustic Droplet Vaporization; Verasonics; Ultrasound; Vaporization Efficiency; Phase-change Contrast Agents;

    Abstract : Acoustic droplet vaporization (ADV) is a process in which a phase shift of a liquified droplet into a gaseous microbubble, is triggered using an ultrasonic wave. In contrast to utilizing conventional contrast agents in ultrasound, the phase change contrast agents used in ADV can extravasate into tumor tissue, and they offer a greater circulatory lifespan, thereby increasing the potential applications in which they can be utilized.
