  1. 1. Wet Spinning of Cellulose-Lignin Precursor for Carbon Fibers : Effect of Coagulation Bath Composition & Spin Finish

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Julia Sundmark; [2023]
    Keywords : Carbon fiber; Cold alkali; Cold NaOH; lignin; cellulose; wet spinning; Kolfiber; kallalkali; lignin; cellulosa; våtspinning;

    Abstract : Carbon fibers (CF) are a material with a composition of over 90% carbon, which has high mechanical properties and low density. This unique combination of properties makes it requirable in applications such as vehicles, aerospace, wind power, and space industries. Commercially made CF are made using the fossil raw material polyacrylonitrile (PAN). READ MORE

  3. 2. Opportunities for increased nutrient recovery at centralised wastewater treatment plants through urine separation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Hanna Gustavsson; [2021]
    Keywords : Nutrient recovery; urine separation; magnesium ammonium phospahte; MAP; ammonium sulphate; AMS; and DHI s WEST;

    Abstract : Municipal wastewater contains a significant amount of nutrients such as phosphorus (P) and nitrogen (N). Therefore have the interest of recovering these nutrients at wastewater treatment plants (WWTP) increased. Nutrient recovery would generate revenue for the WWTP, as it is possible to sell the products as fertiliser. READ MORE

    Abstract : Blåbärsproduktion har ökat i Sverige under 2010-talet, och av de många olika arter av blåbär som finns är det främst Vaccinium corymbosum som odlas. Odlingen kräver näringstillförsel, där kvävet har en viktig roll att spela. READ MORE

  5. 4. Neuroprotective effects of magnesium sulphate evaluated by fluoride resistant acid phosphatase, inorganic phosphate, lactate dehydrogenase and nitric oxide in rats with ischemia

    University essay from Uppsala universitet/Institutionen för kvinnors och barns hälsa

    Author : Maria Dorelis Montero Jimenez; [2020]
    Keywords : Biomarker; Magnesium; Neuroprotection; Respiratory arrest.;

    Abstract : Brain ischemia events are among the first three mortalities causes in the world associated with high treatments costs and in most cases some degree of permanent functional disability, thus it is necessary with new low cost and effective treatments. In the present study the potential neuroprotective effect of magnesium sulphate was evaluated by quantification of ischemic biomarkers: fluoride resistant acid phosphatase (FRAP), inorganic phosphate (Pi), lactate dehydrogenase (LDH) and nitric oxide (NO) in rats with global ischemia.

  6. 5. Recombinant expression of the cowpea chlorotic mottle virus

    University essay from Lunds universitet/Kemiska institutionen

    Author : Amanda Willas; [2019]
    Keywords : Biokemi; Biochemistry; Viruskapsid; Viruscaspid; CCMV; Chemistry;

    Abstract : All viruses are composed of both genetic material and a capsid. The capsid is composed by identical protein subunits and the purpose is protection of the genetic material, in this case RNA. READ MORE
