  1. 21. Screening of ligand binding behavior using a high-throughput method and development of guidelines for a learning material

    University essay from KTH/Lärande

    Author : Oscar Kornher; [2020]
    Keywords : Multimodal chromatography; screening experiments; high-throughput; PCA; learning material; focus group interviews; thematic analysis; crucial steps; coherence and interaction;

    Abstract : This study is comprised of two distinct parts, a chromatographic study and a didactic study.Chromatographic studyThe need for higher selectivity in chromatography purification has increased in recent years. Multimodal resins, offering novel selectivity, are a possible solution to this demand. READ MORE

  3. 22. Investigating In-plane Shear Behaviour of Uncured Unidirectional Prepreg Tapes

    University essay from KTH/Lättkonstruktioner

    Author : Ming Kai Chea; [2019]
    Keywords : ;

    Abstract : Steering of prepreg tows in an automated fibre placement (AFP) process allows geodesic layup trajectory over a doubly-curved surface, as well as the potential to improve the efficiency of composite structures by tailoring their stiffness. However, defects (such as out-of-plane buckling and tow pull off) are commonly generated when the steering radius exceeds a critical limit, which impact the mechanical properties of the finished product.

  4. 23. Correlation of microstructural damage to functional properties of irradiated carbon fibre based composites used in neutron chopper discs

    University essay from Lunds universitet/Hållfasthetslära

    Author : Hanna Molin; [2019]
    Keywords : radiation; epoxy; carbon fiber; CFRP; ESS; European Spallation Source; Technology and Engineering;

    Abstract : Understanding material behaviour has in the past enabled human development and will continue to characterize the various stages of our future development. The use of neutrons will greatly affect several research areas, such as sustainable energy production and cancer research, due to their interaction with nuclei. READ MORE

  5. 24. Biodegradation and ageing of bio-based thermosetting resins from lactic acid

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

    Author : Lara Lopes Gomes Hastenreiter; [2019]
    Keywords : bio-based polymer; lactic acid; glycerol; ethylene glycol; pentaerythritol; biodegradation; ageing; characterisation; DSC; TGA; FTIR; tensile;

    Abstract : The need for replacing petroleum-based polymers has been increasing and bio-based polymers prove to be a suitable solution. The aim of this thesis was to synthesize bio-based resins with different chemical architectures to evaluate the effect of the structure on the properties and on their response to ageing and biodegradation.

  6. 25. A Study of Various Parameters Affecting Adhesion of Coatings to Metal Substrates

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

    Author : Worabhorn Pathanatecha; [2019]
    Keywords : adhesion; coatings; metal substrates; silanes; polyurethanes; surface energy; crosslinking agent; adhesion promoters; vidhäftning; beläggningar; metallunderlag; silaner; polyuretaner; ytenergi; tvärbindningsmedel; vidhäftningspromotor;

    Abstract : The adhesion of coatings is of high importance in the coating industry and a more thorough understanding of adhesion behavior is required. In this thesis work, seven parameters affecting adhesion of silane-modified poly(urethane urea) (PUSi) coatings on pretreated steel and aluminum substrates were studied. READ MORE
