  1. 1. 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

  3. 2. Magnetic properties of a martensitic stainless steel powder : Investigation of magnetic properties for a metallic powder with different sizes and its possible correlation to flow properties

    University essay from KTH/Materialvetenskap

    Author : Carl Back; Saga Grevarp; Arthur Pollet; [2023]
    Keywords : ;

    Abstract : For metal powders, flow properties are important. If the powder does not move properly, it can result in problems with the final product in additive manufacturing. Some of the products created with this manufacturing method are complex and used for important purposes such as medical devices and aerospace. READ MORE

  4. 3. Optimisation of a Powder Dosing Equipment

    University essay from KTH/Kemiteknik

    Author : Andrea Codo Morales; [2023]
    Keywords : mixing; slurry; production; cycles; equipment; blandning; slurry; produktion; cykler; utrustning;

    Abstract : Klimatförändringar är en av de viktigaste problemen som påverkar framtida generationer. För att bekämpa detta införlivar Northvolt hållbara metoder genom hela batteriproduktionsprocessen. Ett avgörande steg i elektrodtillverkningen är slurryblandningen, vilket innebär att man kombinerar flera pulver inklusive det aktiva materialet. READ MORE

  5. 4. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels

    University essay from KTH/Materialvetenskap

    Author : Atharva Kotasthane; [2023]
    Keywords : Hardenability; Martensite; Simulation Modelling; Microhardness; Microstructure; Härdbarhet; Martensit; Simuleringsmodellering; Mikrohårdhet; Mikrostruktur;

    Abstract : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. READ MORE

  6. 5. External powder feed

    University essay from Mittuniversitetet/Institutionen för ingenjörsvetenskap, matematik och ämnesdidaktik (2023-)

    Author : Emil Rudh; [2023]
    Keywords : Additive Manufacturing; AM; EBM; Material feeding; PBF; Powder feeding; Additiv tillverkning; AM; EBM; Materialmatning; PBF; Pulvermatning;

    Abstract : Syftet med detta projekt var att undersöka möjligheterna att externt mata in pulver i en PBF-maskin (en EBM-maskin, Electron Beam Melting), för att öka maskinens effektivitet. Huvudmålet med projektet var att designa ett sätt att leverera pulver till byggkammaren från en extern källa. READ MORE
