    • Chemical changes in biomass during torrefaction 

      Shoulaifar, Tooran Khazraie
      Åbo Akademi, Faculty of Science and Engineering, Johan Gadolin Process Chemistry Centre : 16-01 (Åbo Akademi University, Johan Gadolin Process Chemistry Centre, 22.01.2016)
      Torrefaction is moderate thermal treatment (~200-300 °C) of biomass in an inert atmosphere. The torrefied fuel offers advantages to traditional biomass, such as higher heating value, reduced hydrophilic nature, increased ...

    • Functional cellulose microspheres for pharmaceutical applications 

      Trygg, Jani (Åbo Akademi - Åbo Akademi University, 13.02.2015)
      Dissolving cellulose is the first main step in preparing novel cellulosicmaterials. Since cellulosic fibres cannot be easily dissolved in water-based solvents, fibres were pretreated with ethanol-acid solution prior to the ...

    • Ionic liquid mediated biomass deconstruction: from analysis challenges to fermentable sugars 

      Hyvärinen, Sari (Åbo Akademi - Åbo Akademi University, 22.09.2014)
      Ionic liquids, ILs, have recently been studied with accelerating interest to be used for a deconstruction/fractionation, dissolution or pretreatment processing method of lignocellulosic biomass. ILs are usually utilized ...

    • Supramolecular design of cellulose-based hydrogel beads 

      Trivedi, Poonam (Åbo Akademi - Åbo Akademi University, 08.03.2019)
      The degree of polymerization (DP) of cellulose fibres is an important factor to consider during dissolution in water-based solvent system and to design further advanced biomaterials. The lower is the DP, the higher cellulose ...
