  1. 21. Development of polymer based composite filaments for 3D printing

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Elin Åkerlund; [2019]
    Keywords : 3D-printing; fused deposition modeling FDM ; composite filaments; biocompatible materials; biodegradability; medical applications; scaffold materials; poly lactic acid PLA ; polycaprolactone PCL ; hydroxyapatite HA ; mechanical properties; thermal stability; chemical composition; morphological characterization; accelerated degradation study; polymer degradation behavior;

    Abstract : The relatively new and still growing field of 3D-printing has opened up the possibilities to manufacture patient-specific medical devices with high geometrical accuracy in a precise and quick manner. Additionally, biocompatible materials are a demand for all medical applications while biodegradability is of importance when developing scaffolds for tissue growth for instance. READ MORE

  3. 22. Catalytic hydrotreating of lignin

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Markus Lilja; [2019]
    Keywords : Lignin; hydrotreating; kemiteknik; chemical engineering; Chemistry; Technology and Engineering;

    Abstract : One of the main challenge’s society faces today is climate change caused by CO2 due to the de-pendence on fossil fuels. To combat the increasing CO2 levels there is a need to develop renewable fuels. One such fuel could potentially be derived from lignin. In this thesis, lignin derived from a pulp and paper mill was first treated and cleaned. READ MORE

  4. 23. Gripper Tool Designed for a Surgical Collaborative Robot

    University essay from KTH/Medicinteknik och hälsosystem

    Author : Emma Andersson; [2019]
    Keywords : Medical robotics; Surgical Suturing; Gripper Tool; Design Methodology; Double Diamond Design process; Medicinskrobotik; Kirurgisksuturering; Gripdon; Design metodik; Double Diamond Design-process;

    Abstract : In surgery, suturing is the use of needle and thread to join cut and/or damaged anatomical structures together. This repair strategy is highly versatile and is universal for all types of surgery as the goal is to restore, repair or improve function and/or appearance. READ MORE

  5. 24. Development and Characterization of a Sustainable Lignin-based Composite Material

    University essay from KTH/Materialvetenskap

    Author : Giacomo De Ferrari; [2018]
    Keywords : ;

    Abstract : Lignin is the most abundant aromatic polymer of natural origin on earth. Currently, it is treated as a waste product of the paper production industry and is burnt as fuel to generate energy. READ MORE

  6. 25. Development of method for processing brittle-hard materials using Laser Metal Deposition (LMD)

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

    Author : Alejandro Simó Vesperinas; [2018]
    Keywords : Additive Manufacturing AM ; Laser Metal Deposition LMD ; Direct Metal Deposition DMD ; High-temperature materials; Mo-Si-B alloy; Residual stress; Cracks;

    Abstract : New materials capable of operating at ultra-high temperatures in gas turbine engines are highly desired. Materials such as silicides of refractory metals present great potential to substitute single crystal nickel-based superalloys. READ MORE
