    Abstract : RISE Bioeconomy is working with the biorefinery concept. That is, for the company, to utilize all wood derivatives in effective processes, resulting in unique products. RISE Bioeconomy is investigating the possibilities of producing holocellulose through an oxidative delignification process of wood, using peracetic acid (PAA). READ MORE

  3. 17. Assessment on Groundwater Contamination from a Former Hard Chromium Plating Site in Iggesund

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Isabell Alnehem; [2016]
    Keywords : ;

    Abstract : Before the persistent and toxicological properties of perfluoroalkyl and polyfluoroalkyl substances (PFASs) were known they were used worldwide. The thermal and chemical stability from the carbon-fluorine bond makes these substances desirable for industrial applications. READ MORE

  4. 18. Analysis of Per- and Polyfluoroalkyl Substances (PFASs) in African Darter (Anhinga rufa) Eggs along Vaal River, South Africa : Comparison of Homologue and Isomer Profiles

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Felicia Fredriksson; [2016]
    Keywords : Per- and polyfluoroalkyl substances PFASs ; Perfluorooctane sulfonate PFOS ; linear and branched isomers; African Darter; Vaal River; bird eggs; Per- och polyfluoralkylerade substanser PFASs ; perfluoroktansulfonat PFOS ; linjära och grenade isomerer; African Darter; Vaal River; fågelägg;

    Abstract : Per- and polyfluoroalkyl substances (PFASs) are a group of toxic and persistent organic compounds. Their properties make them extremely resistant and they have been shown to have bioaccumulation and toxic properties in the environment and also to biomagnify in both aquatic and terrestrial food webs.

  5. 19. The Influence of Carboxylic Acid in Packaging Materials

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Jonas Mattisson; [2016]
    Keywords : food packing; Packaging Material; Carboxylic Acid; delamination; adhesion; polymer technology; polymerteknologi; Technology and Engineering;

    Abstract : Tetra Pak delivers food packing services world-wide and uses multilayer packaging materials to protect the food product from being affected by the environment. Loss of adhesion between the polymer and the aluminium layer in Tetra Paks packaging materials has proven to be a serious problem casing the package to lose its integrity and the food product to spoil.

  6. 20. Development of a quantum dot based strategy for Gram-specific bacteria differentiation

    University essay from KTH/Skolan för teknik och hälsa (STH)

    Author : Ann-Lena Jahnsen; [2016]
    Keywords : Nanoparticles; Quantum dots; Bioconjugation; Diagnostics; Gram-specific; Bacteria detection;

    Abstract : Abstract Time-consuming diagnosis of bacterial blood stream infections and inappropriate antibiotic therapy have critical implications for patient outcome – with mortality figures rising for every hour of delayed treatment. The development of diagnostic methods that are capable of selective and rapid bacteria detection, and do not rely on preliminary blood culturing and Gram-staining procedures, is imperative in providing effective therapy and preventing multi-resistance.
