  1. 1. Surface functionalization of cellulose fibers and exploration of its influence in ion exchange chromatography

    University essay from KTH/Fiber- och polymerteknologi

    Author : Anna Wessén; [2023]
    Keywords : Ion-exchange chromatography; membrane chromatography; surface extension; grafting; copolymerization; free-radical polymerization; Jonbyteskromatografi; membrankromatografi; ytförlängning; ympning; sampolymerisation; fri radikal polymerisation;

    Abstract : 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.

  3. 2. The effect of fiber structure on chemical modification of cellulosic fibers

    University essay from KTH/Kemiteknik

    Author : Hedvig Palm; Linn Palmér; Emil Törnqvist; Alexander de Potocki; [2023]
    Keywords : Kemi; cellulosa; substitutionsgrad; pappersmassa; katjonisering; EPTMAC; CHPTAC; hållbarhet; blekt sulfatmassa; oblekt sulfatmassa; CTMP; dissolvingmassa; modifierad cellulosa;

    Abstract : För att skapa ett hållbart samhälle måste material av fossilt ursprung ersättas med förnyelsebara och miljövänliga alternativ. Ett sådant alternativ är cellulosa från vedfibrer, som har stor potential att kunna ersätta många fossila material i framtiden. READ MORE

  4. 3. The Impact of Insulation Materials on a Climate Declaration : A Study of a Swedish Preschool

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Isabelle Hallkvist; Elin Nilsson; [2021]
    Keywords : Climate declaration; Insulation materials; Insulation material; Climate impact; Greenhouse gas emissions; Building and construction sector; Boverket; Glass wool; Stone wool; EPS; XPS; Cellulose fibre; Foam glass; Klimatdeklaration; Isoleringsmaterial; Klimatpåverkan; Växthusgasutsläpp; Bygg- och fastighetssektorn; Boverket; Glasull; Stenull; EPS; XPS; Cellulosafiber; Skumglas;

    Abstract : To reach the net-zero carbon goal by 2045, the Swedish government want to push the building and construction sector to lower their greenhouse gas emissions. This push is performed by implementing a law requiring building developers to perform a climate declaration over greenhouse gas emissions, to receive a building’s final clearance. READ MORE

  5. 4. Gas Emissions from Contaminated Fibrous Sediments in Sweden

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Fredrik Collin; [2020]
    Keywords : Fiberbank; fibrous sediment; gas ebullition; GHG emissions; methanogenesis; optical ebullition sensor; Fiberbank; fibersediment; gas ebullition; växthusgas emissioner; metanogenes; optiska ebullitions sensore;

    Abstract : Gas Emissions from Contaminated Fibrous Sediments in Sweden The discharge of untreated wastewater from pulp and paper mills have resulted in the accumulation offibrous sediments on the bottom of many nearby aquatic recipients. Some accumulations are multiplemeters thick and consist almost entirely of cellulose fibre or wood chips; these are called fiberbanks. READ MORE

  6. 5. Influence of level of cellulose oxidation and surface treatment on the adhesion between cellulose beads

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

    Author : Rasmus Källgren; [2020]
    Keywords : Cellulose; Fibre; Surface Coating; Layer-by-Layer; Oxidation; Cellulosa; Fiber; Ytbehandling; Layer-by-Layer; Oxidation;

    Abstract : With the growing impact of climate change on both political decisions and how companies develop their products, it is increasingly important to find environmentally friendly alternatives to fossil-based materials. One of the more interesting materials in this respect is cellulose, which is the world's most naturally occurring polymer and can be used in a variety of applications. READ MORE
