  1. 1. PLASTER CASTS AND CORROSION AN EXPERIMENTAL STUDY ON REMOVAL OF CORROSION PRODUCTS FROM PLASTER CASTS

    University essay from Göteborgs universitet/Institutionen för kulturvård

    Author : Gabriella Zimmerman; [2023-11-07]
    Keywords : plaster cast conservation; iron corrosion staining; xanthan gel; Arbocel®; latex cleaning; chelating agents;

    Abstract : Conservation of plaster casts is complex due to the nature of the material itself. Corrosion of armature and metal structural supports is one of the most common causes of damage in plaster casts and subsequent corrosion staining. READ MORE

  3. 2. Formulation and characterisation of novel edible-packaging for fruits and vegetables

    University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

    Author : Lola Sutton; Katerina Papa; [2023]
    Keywords : algae; edible packaging; carrageenan; cucumber; REL; oxidative stress; antioxidants; food engineering; Technology and Engineering;

    Abstract : This master's thesis investigated the potential of algae raw materials, specifically k-carrageenan and to a lesser extent alginate, as film-forming ingredients for the development of a novel edible packaging solutions. The project involved the testing and characterisation of several active ingredients of algal and plant origins both as extracts and as ingredients in films. READ MORE

  4. 3. The discoloration of polyethylene obtained from chemical separation of laminates: Investigating additives and other potential causes

    University essay from Lunds universitet/Förpackningslogistik

    Author : Can Feng; [2021]
    Keywords : Delamination; multilayered packaging; polymer discoloration; plastic film; recycling; Technology and Engineering;

    Abstract : PolyAl, the material composed of laminated polyethylene (PE) films and aluminum (Al) in carton, is a challenge in recycling due to the strong adhesion of the layers and the low value of the end products. In Europe, recent efforts to improve the circularity of carton packages include the chemical separation of PolyAl, in order to obtain higher values of the PE and Al separately. READ MORE

  5. 4. Spectroscopy and RGB-Colorimetry for Quantification of Plant Pigment and Fruit Content in Fruit Drinks

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Daniele Correia Rodman; [2018]
    Keywords : spectroscopy; RGB-colorimetry; Physics and Astronomy;

    Abstract : Collimated Transmission Spectroscopy (CTS) is a technique that is commonly used to study the optical absorption of different media. In this work CTS was used to measure the absorbance of pure raspberry juice in order to investigate how well the fruit content may be determined in a commercially available raspberry fruit drink.
