  1. 6. Preparation and evaluation of arabinoxylan based prebiotics

    Master-uppsats, Lunds universitet/Bioteknik (master)

    Författare :Mohammad Abu Mursalin Sajib; [2018]
    Nyckelord :Arabinoxylan; Probiotics; Prebiotics; Food; Xylanase; Brewer s spent grain; Biotechnology; Bioteknik; Technology and Engineering;

    Sammanfattning : Prebiotics are non-digestible carbohydrates that selectively stimulate the growth and activity of health promoting bacteria in the colon, resulting in homeostasis to the gut environment. It is considered to be the solution of many health-related diseases such as type-2 diabetes, cardiovascular disease and cancer. LÄS MER

  3. 7. Preparation and characterization of nanocellulose from wheat bran

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Claes Nilsson; [2017]
    Nyckelord :Spherical nanocellulose; Nanocellulose; Wheat bran; Cellulose; Renewable; chemical engineering; kemiteknik; Technology and Engineering;

    Sammanfattning : Nanocellulose is being studied to a great extent around the world as it has great potential and many possible applications, for example, as an additive in greener polymers in a world where the need for replacements for fossil fuel based polymers increase. Different sources of cellulose are being considered for the production of nanocellulose as this can add value to what otherwise often is a by-product. LÄS MER

  4. 8. Separation for regeneration : Chemical recycling of cotton and polyester textiles

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Stina Björquist; [2017]
    Nyckelord :cotton polyester blends; chemical recycling; alkaline hydrolysis;

    Sammanfattning : In 2015, 96.7 million tonnes of textile fibres were produced world-wide. Our high consumption of textiles leads to an increased amount of textile waste. In Sweden, the majority of used clothing and textiles are incinerated due to the lack of recycling techniques. LÄS MER

  5. 9. Teknisk utvärdering av en ny miljövänlig förbehandlingsmetod av biomassaavfall med utspädd salpetersyra

    Magister-uppsats, Högskolan i Borås/Institutionen Ingenjörshögskolan

    Författare :Li Zhi; Oliver Murgårdh; [2012]
    Nyckelord :lignin; cellulosic ethanol; sweet liquor; pre-treatment; dilute nitric acid pulping; SSF; SHF; cellic ctec2; yeast; NABC; bio-refining;

    Sammanfattning : Bio-refining of renewable resources such as waste biomass into value added products has increased rapidly over the last decades. The aim is to find new environmentally friendly yet economically feasible ways of replacing current utilization of non renewable resources. LÄS MER

  7. 10. Oxidative Degradation of Polyether In Contact with Minerals

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Sandra Dabbagh; [2011]
    Nyckelord :adhesive; polyether; degradation; oxidation; glue;

    Sammanfattning : Oxidative degradation of adhesives based on silane terminated polypropylene oxide and polypropylene oxide (PPO) was studied. The combination of rapeseed oil and PPO as plasticizer in the parquet adhesive gave rise to oxidative degradation in contact with screeds of certain minerals. LÄS MER
