1. Surface functionalization of cellulose fibers and exploration of its influence in ion exchange chromatography
University essay from KTH/Fiber- och polymerteknologiAbstract : Kromatografiska metoder kan användas för en mängd olika tillämpningar, inklusive separation, rening och analys av biomolekyler och kemikalier. Membrankromatografi är en av de nya kromatografiteknikerna som expanderar snabbt eftersom den tillåter hög masstransport genom den stationära fasen, vilket resulterar i en mer tidseffektiv process.

2. Synthesis and Investigation of Nitrile-Containing Polymers Inspired by Lignin
University essay from Lunds universitet/Centrum för analys och syntesAbstract : The lignin-inspired derivatives coniferyl aldehyde and sinapyl aldehyde were used to prepare nitrile-containing methacrylate monomers with the aim to synthesize bio-based polymers exhibiting high glass transition temperatures (Tgs). The aldehydes were initially transformed to the corresponding nitriles and then underwent methacrylation before being polymerised by free-radical polymerisation. READ MORE

3. Modification of lignin derivatives for polymerization in water
University essay from KTH/YtbehandlingsteknikAbstract : För att möjliggöra en hållbar utveckling skiftar många polymerforskares fokus just nu från att syntetisera polymerer från fossila resurser till att producera biobaserade polymerer från exempelvis träd. Av särskilt intresse är lignin, som utgör ungefär en tredjedel av allt växtmaterial men i nuläget oftast används som bränsle. READ MORE

4. Ferulic Acid – A Valuable Natural Compound for Sustainable Materials
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)Abstract : One of the largest problems that stands before us is the quest to find sustainable alternatives to fossil-based materials. Fossil-based products can be found all around us in our society. This quest has forced us to look for new ways to build materials. READ MORE

5. Polymerization of Zwitterionic Sulphobetaine Methacrylate and Modification of Contact Lens Substrate
University essay from KTH/Skolan för kemivetenskap (CHE)Abstract : In this study, the zwitterionic monomer [2-(methacryloyloxy)ethyl] dimethyl-(3-sulfopropyl) ammonium hydroxide (SBMA) was polymerized in a controlled manner by reversible addition-fragmentation chain transfer (RAFT) polymerization. The SBMA was also polymerized by atom transfer radical polymerization (ATRP) but in a less controlled manner why ATRP was discarded for further use in the study. READ MORE
