  1. 16. Laser Scattering for Fast Characterization of Cellulose Filaments

    University essay from KTH/Fiber- och polymerteknologi

    Author : Alexandra Konstantinidou; Saga Holmström; Susanna Hellberg; [2022]
    Keywords : Cellulose nanofibrils; Fibers; Sustainable development; Bio-based material; Characterization; Microscale; Microscopy; Small-angle light scattering; Laser diffraction; Cellulosananofibriller; Fiber; H˚allbar utveckling; Biobaserade material; Karakterisering; Mikroskala; Mikroskopi; Ljusspridning; Laserdiffraktion;

    Abstract : Cellulosananofibriller (CNFs) hör till naturens mest fundamentala byggstenar och förser naturliga material, såsom den yttre cellväggen i trä, med en otrolig styrka och styvhet. Genom att imitera träets arkitektur öppnas möjligheter upp för tillverkning av nya, biobaserade och lättviktiga strukturella material med mekaniska egenskaper som överskrider de för glasfiber, metaller och legeringar.

  3. 17. Fibre volume fractions’ and printing directions’ effects on tribological and mechanical properties in FDM printed carbon fibre reinforced PEEK : Suitability assessment of FDM printed PEEK-CF to act in a steam engine’s ball joint, by analysis of compressive properties, impact strength, friction and wear

    University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Author : William Tönnberg; [2022]
    Keywords : Ranotor; steam engine; PEEK; polyether-ether-ketone; carbon fibre reinforced PEEK; impact strength; compressive strength; compressive modulus; friction; wear; tribology; FFF; FDM; 3D-printing; printing parameters;

    Abstract : The purpose with this study was to investigate FDM/FFF manufactured carbon fibre reinforced PEEK and assess its suitability to act as a sealing- and bearing material in a modern steam engine’s ball joint. The steam engine is totally free from oil due to the risk of water- and steam contamination. READ MORE

  4. 18. DURABILITY STUDY OF REJUVENATED RAP BINDERS

    University essay from KTH/Kemiteknik

    Author : An Na Lay; [2022]
    Keywords : RAP reclaimed asphalt pavement ; rejuvenator; bitumen; rheology; ageing; RAP; bitumen; föryngringsmedel; reologi; åldring;

    Abstract : När priset på naturtillgångar ökar samt att industrier måste ställa om till en mer hållbar verksamhet innebär detta även en omställning för asfaltsindustrin. Ett sätt för att använda mer återvunnet material i asfaltsindustri är att använda bindemedlet från gammal asfaltsmassa (eng.: reclaimed asphalt pavement, RAP). READ MORE

  5. 19. P-Casso : The horizontal drawing robot

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Oscar Kåreby; Sigge Sundqvist; [2022]
    Keywords : Arduino; Chalk; Drawing; Mecanum Wheel; Mechatronic; Robot; Drawbot; Arduino; Krita; Rita; Mecanumhjul; Mekatronik; Robot; Ritbot;

    Abstract : To define art is no easy task. Quotes such as ”Art is the elimination of the unnecessary” and ”A picture is worth a thousand words”, implies that art has something to do with conveying information. This is compatible with the fact that instructions are often conveyed in the form of images instead of text. READ MORE

  6. 20. Improvement of the substrate layer in a photovoltaic system for neural implants

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Justina Venckute Larsson; [2022]
    Keywords : Bioengineering; Photovoltaic; substrate; neural implant; Parylene C; Bioteknik; solceller; substrat; neurala implantat; Parylen C;

    Abstract : Neural implants have been developed to aid with different neurological disorders. Although there are neural implants that are used to treat patients today, there is still room for improvement in the field. READ MORE
