  1. 31. The dependence of chromatographic conditions for separation of oligonucleotides in different AEX-HPLC columns

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

    Author : Julia Nylander; [2020]
    Keywords : ion exchange chromatography; oligonucleotides; anion exchange column; pH; HPLC; Jonbyteskromatografi; oligonukleotider; anjonbytarkolonn; pH; HPLC;

    Abstract : Oligonucleotides (ONs) are widely used in different applications in life science, forensic, in i.e. family tree DNA test for humans and in diagnostic applications in several fields. READ MORE

  3. 32. Challenges in food system development for deep space missions

    University essay from SLU/Department of Molecular Sciences

    Author : Tor Blomqvist; [2020]
    Keywords : space food; deep space; microgravity; Mars; space food systems; bioregenerative food systems; food processing;

    Abstract : With a reinvigoration of space travel, space agencies around the world collaborate to land the first woman and the next man on the moon by 2024, establish a moonbase with a constant human lunar presence by 2028 and bring humans to Mars by 2030. Even though we may have the technology to bring humans to Mars, we do not have the required food systems and the food technology to sustain them. READ MORE

  4. 33. Die life prediction using High Pressure Die Casting simulations

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Halses Sebastian Sivertsen; [2020]
    Keywords : HPDC; simulations; aluminum alloys; MAGMAsoft;

    Abstract : Global trends in automotive industry for weight reduction drives an interest for casting of structural aluminum parts. High pressure die casting (HPDC) is chosen for this purpose since it enables manufacturing of large series parts where complexity and repeatability is demanded. READ MORE

  5. 34. Effect of Induction-Heat Post-Curing on Residual Stresses in Fast-Curing Carbon Fibre Reinforced Composites

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

    Author : Mercedes Amelia Bettelli; [2020]
    Keywords : Carbon Fibres Reinforced Polymer Composite; epoxy resins; cure behaviour; residual stress and shape distortions;

    Abstract : Manufacturing induced shape distortions is a common problem for composite materials. Due to the non-isotropic nature of carbon fibre reinforced polymers (CFRP) unavoidable deformations occur during part production. During fabrication of polymer composites, the material obtains its final shape at elevated temperatures. READ MORE

  6. 35. Tribological characterisation of additively manufactured hot forming steels

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

    Author : Anna Vikhareva; [2020]
    Keywords : High temperature tribology; additive manufacturing; hot stamping; maraging steel; H13; galling;

    Abstract : Over the last decade, the application of ultra-high strength steel as safety components and structural reinforcements in automobile applications has increased due to their favourable high-strength-to-weight ratio. The complex shaped components are widely produced using hot stamping. READ MORE
