  1. 21. Protected Lignin Biorefining: Fundamental Insights on Lignin Reactivity

    Författare :Maria Karlsson; Martin Lawoko; Åsa Emmer; Olena Sevastyanova; John Ralph; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Sustainability; lignin; biorefinery; cyclic organosolv extraction; preserved structure; NMR; MALDI-TOF MS; Hållbarhet; lignin; bioraffinaderi; cyklisk organosolv extraktion; bevarad struktur; NMR; MALDI-TOF MS; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The potential to utilize lignin, which constitutes as much as 15-30% of the biomass, needs further evaluation. In the transition towards a bioeconomy, lignin has the potential to replace fossil-based phenols. Attempts to valorize the available technical lignins are ongoing; however, that lignin suffers from molecular heterogeneity. LÄS MER

    Sammanfattning : Organic electrical energy storage (EES) is a growing field of research that is expected to play an important role in the future, as the need for sustainable EES increases. Conducting redox polymers (CRPs), i.e. conducting polymers with incorporated redox active moieties e. LÄS MER

  7. 25. Additive Manufacturing of Ferritic Materials : A Journey from Stainless Steels to High-Entropy Alloys

    Författare :Dennis Karlsson; Ulf Jansson; Martin Sahlberg; Eduard Hryha; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Additive Manufacturing; Laser Powder Bed Fusion; Binder Jetting; Ferritic Stainless Steel; High Entropy Alloy; Mechanical Properties;

    Sammanfattning : Design of new materials with complex geometries is an important part of new innovative solutions for technical applications. With the use of additive manufacturing (AM), the design possibilities are endless and geometries that are impossible to manufacture by conventional techniques are available. LÄS MER
