  1. 1. Investigation of the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Gila van den Eijnde; [2023]
    Nyckelord :Hard candy; Sugar composition; Hygroscopicity; Moisture absorption; Shelf life; Product stability; Food technology; Technology and Engineering;

    Sammanfattning : Hard candy is hygroscopic, implying that hard candy readily absorbs moisture from the environment, resulting in adverse changes in the texture and appearance of the candy. This thesis investigates the impact of different sugar compositions on the moisture absorption of hard candy when exposed to a humid environment. LÄS MER

  3. 2. A Feasibility Analysis of Natural Composite Alternatives in High Performance Sailing Vessels

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Sabrina Smith; [2023]
    Nyckelord :F50 catamaran; sustainable materials; marine applications; flax laminates; mechanical testing; environmental analysis; weight distribution; yacht performance;

    Sammanfattning : The construction of high-performance vessels like the F50 catamaran has traditionally prioritized advanced composite materials and performance-driven design. However, there is a growing need to incorporate sustainable materials and practices, with their performance in marine applications remaining relatively unknown. LÄS MER

  4. 3. A Study on Lignin or Zein Based Hydrophobic Coatings

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Filippa Wentz; Sandra Olofsson; [2023]
    Nyckelord :Lignin; Zein; Hydrophobic Coating; Dispersion; Chemical engineering; Technology and Engineering;

    Sammanfattning : The two by-products lignin, from the paper industry, and zein, from starch production, have shown potential as hydrophobic barriers. Therefore, this study has aimed to produce and in-vestigate the hydrophobicity of lignin or zein dispersions coated on paper. LÄS MER

  5. 4. Towards climate optimised riparian buffer zones in boreal forests

    Master-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :Alice Falk; [2022]
    Nyckelord :Forestry; Biogeochemical hotspots; Carbon dioxide; Methane;

    Sammanfattning : Boreal forests have the potential to mitigate the increased concentrations of greenhouse gases (GHGs) in the atmosphere. However, forestry alters the soil biogeochemical processes which can cause an increase in GHG emissions from nearby water bodies, soil and vegetation. LÄS MER

  7. 5. Influence of Humidity Over the Properties of Wood Fiber-based Biocomposites

    Kandidat-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Arvid Hedin; Anna Kudinova; Linnea Masso; [2022]
    Nyckelord :Wood Polymer Composite; WPC; Relative Humidity; RH; Tensile Testing; Polypropene; FibraQ; Wood Fiber; Surface Treatment; Mechanical Properties;

    Sammanfattning : The project aims to develop a methodology to study the variation in properties of wood polymer composites (WPC’s) with/without surface treatment at different humidity conditions. The project aims to investigate the behavior of biocomposites at 50%, 80%and 100% relative humidity (RH). LÄS MER
