  1. 1. Anaerobic cellulose degrading bacteria isolated from biogas plants

    University essay from SLU/Department of Molecular Sciences

    Author : Caroline Sjöberg; [2023]
    Keywords : anaerobic bacteria; biogas; cellulose; cellobiose; VFA; enzyme activity; TRFLP;

    Abstract : Two cellulose degrading bacteria, named BCISO-4 and DC1-18-4, were isolated from samples retrieved from two large scale biogas-plants. In order to investigate and determine information regarding their growth preferences multiple tests were performed. READ MORE

  3. 2. Filtration of oil-in-water nanoemulsions for potential adjuvant development applications

    University essay from KTH/Kemiteknik

    Author : Emilie Degeneve; [2023]
    Keywords : Filtration of oil-in-water nanoemulsions for potential adjuvant development applications; Vaccin; adjuvans; nanoemulsion; ytaktiva ämnen; filtrering;

    Abstract : I den här studien undersöktes innovativa sammansättningar för produktion av vaccinadjuvans. Syftet var att stabilisera nanoemulsioner av olja i vatten, med hjälp av squalenolja (som används inom läkemedelsindustrin), med olika ytaktiva ämnen och att testa filtrerbarheten hos dessa nanoemulsioner.

  4. 3. ROP in novel biobased ionic liquids towards cellulose functionalization

    University essay from KTH/Fiber- och polymerteknologi

    Author : Rebecca Mattsson; [2023]
    Keywords : Ionic liquids; SI-ROP; coROP; polyesters; cellulose; Jonvätska; yt-initierad Ringöppnings-polymerisation; ringöppnings-sampolymerisation; polyestrar; cellulosa;

    Abstract : Ett nytt sätt att aktivera cellulosa för kemisk modifiering med hjälp av en miljövänlig process har utvecklats innan starten av detta projekt. Två versionen av den nyskapade betain-baserade jonvätskan, BBIL har syntetiserats, en som använder mesylat som motjon, M-BBIL och en som använder acetat, A-BBIL. READ MORE

  5. 4. A GREENER SOLUTION Investigating the potential use of Green Solvents to remove cellulose nitrate lacquer from silver objects

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Borén Evelina; [2022-07-05]
    Keywords : Sustainable Conservation; Green Solvents; Cellulose Nitrate; Lacquer; Coating; Silver;

    Abstract : This thesis investigates the performance of non-hazardous solvent substitutes, so called “Green Solvents", for the removal of aged and unaged cellulose nitrate lacquer from silver surfaces. Literature research and preliminary tests resulted in four solvents of interest: ethyl acetate, ethyl lactate, propylene carbonate and dimethyl carbonate. READ MORE

  6. 5. The Use of Gels for the Removal of Cellulose Nitrate Lacquer on Silver

    University essay from Göteborgs universitet/Institutionen för kulturvård
