  1. 1. Evaluating the feasibility of chitosan as an adhesive for wood laminates and as a matrix for transparent wood

    University essay from KTH/Fiber- och polymerteknologi

    Author : Nihar Sakhadeo; [2023]
    Keywords : Transparent wood; Chitosan; Biobased adhesives; Biopolymers; Laminate; Transparent trä; Kitosan; Biobaserad adhesiv; Biopolymer; Laminat;

    Abstract : En av grundpelarna i alla hållbara system är införandet av en cirkulär ekonomi, som främjar återanvändning och återvinning av material. Plast är en av i utmaning i detta avseende på grund av den stora produktionsvolymen variation i sorter och långsamma nedbrytn. READ MORE

  2. 2. Varnishing of Fiber-based Closures

    University essay from Lunds universitet/Förpackningslogistik

    Author : Nisha Sunil David; [2023]
    Keywords : Varnishing; fiber-based closures; water-based spray coating; packaging; repulpability ; Technology and Engineering;

    Abstract : This research aims to investigate water-based varnishes and technologies to coat fiber-based closures to attain water barrier properties. To ensure recyclability the repulpability of coated and uncoated lids is tested. The research approach is exploratory. READ MORE

  3. 3. GRAPHENE MODIFIED E-TEXTILE : AN INDUSTRY RELEVANT APPROACH OF DOPING AND VISUALISING A FULLY TEXTILE P-N JUNCTION DIODES

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Bilel Meskini; [2023]
    Keywords : E-textile; viscose; polyester; graphene; graphene oxide GO; reduced graphene oxide rGO; tannic acid; plasma treatment; electrochemical deposition; doping; semiconductor;

    Abstract : As a wonder material, graphene has been studied in various applications due to its exceptional properties. Recently it has been used in textile to obtain functionalised garments as E-textile. From an industry-relevant perspective, it is essential to introduce a process that could be scaled-up. READ MORE

  4. 4. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Anna Wagne; [2023]
    Keywords : Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

    Abstract : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. READ MORE

  5. 5. An Investigation of How Hydrophobicity, Water, and Surface Topography Influence Macroscopic Particle Accumulation on Surfaces : A Case Study of Grass Accumulation on Robotic Lawn Mower

    University essay from Jönköping University/JTH, Industriell produktutveckling, produktion och design

    Author : Rasmus Brask-Nilsen; Petter Ydrestrand; [2023]
    Keywords : Macroscopic Particles; Accumulation; Hydrophobicity; Humidity; Topology; Adhesion; Experiments; Design of Experiments; Grass; Robotic Lawn Mower;

    Abstract : This master's thesis project investigates the impact of hydrophobicity and topology on dry and wet macroscopic particle accumulation on surfaces. The report begins by outlining the challenges associated with this phenomenon and the existing theories and methods used to study it, including adhesion, surface engineering, the Lotus effect, and humidity.
