  1. 1. Polymer extraction and utilization of brown algal biomass

    Författare :Martin Sterner; Ulrica Edlund; Fredrik Gröndahl; Marguerite Rinaudo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Algae; Saccharina latissima; alginate; brown seaweed; extraction; filament; chelation; gel; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : Aquaculture is a field with a world changing potential. The areas at sea are enormous and aquatic cultivations impact both the environment and local ecology far less than land based cultivations. In the realm of algae, abundancies exists of nutrition, water and accessible sunlight, but there is constant shortage of places to dwell. LÄS MER

  3. 2. Towards more selective sorbents for extraction of drugs and biomarkers from biological fluids using molecularly imprinted polymers

    Författare :Mohammad Mahdi Moein; Mohamed Abdel-Rehim; Milton L. Lee; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; molecularly imprinted polymer; sol-gel; solid phase extraction; microextraction by packed sorbent; monolithic column; Analytical Chemistry; analytisk kemi;

    Sammanfattning : Sample preparation has a critical role as a first step in analytical processes, especially in bioanalysis and environmental analysis. A good sample preparation technique should be robust and stable, regardless of the sample matrix. LÄS MER

  4. 3. Exploring the functionality of coconut proteins

    Författare :Borges Chambale; Livsmedelsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coconut; coconut milk; extraction; proteins; emulsions; functional properties; denaturation; gels; yield stress; glass structure;

    Sammanfattning : At present, coconut proteins are discarded as a waste product by the coconut oil industry. If the range of applications of coconut proteins is to be expanded, their potential functionalities should be investigated. Emulsions and gels are of the greatest interest in food industry. LÄS MER

  5. 4. The use of fluorescence techniques for the study of some membrane-bound photosynthetic properties and some effects of copper on the thylakoid membrane

    Författare :Göran Samuelsson; N. Valanne; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chlorophylI-protein complexes; sequential extraction; ß-carotene low temperature fluorescence emission; absorption; in vivo chi. a fluorescence; copper; electron transport;

    Sammanfattning : Lyophilized pea chloroplasts were extracted in a stepwise manner in an organic solvent (petroleum ether) with increasing polarity which was obtained by addition of small amount of ETOH (0-1 %). Absorption and low temperature fluorescence emission spectra were measured on both the extracted thylakoids and on isolated chlorophylI-protein complexes. LÄS MER

  7. 5. Removal of endocrine-disrupting compounds from wastewater using molecular imprinting

    Författare :Mathieu Le Noir; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; molecular imprinting; Endocrine-disrupting compounds; wastewater; macroporous gel; trace contaminants;

    Sammanfattning : Endocrine-disrupting compounds (EDCs) such as hormones and certain pharmaceuticals (i.e. birth control pills, oestrogen replacement products and other steroids) can interfere with the regulatory systems of humans and wildlife. Many of these compounds are excreted by humans and released with sewage. LÄS MER
