  1. 1. Optical Communication using Nanowires and Molecular Memory Systems

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Thomas Kjellberg Jensen; [2024]
    Nyckelord :neuromorphic computing; nanowire; molecular dye; DASA photoswitch; OBIC; Physics and Astronomy;

    Sammanfattning : Neuromorphic computational networks, inspired by biological neural networks, provide a possible way of lowering computational energy cost, while at the same time allowing for much more sophisticated devices capable of real-time inferences and learning. Since simulating artificial neural networks on conventional computers is particularly inefficient, the development of neuromorphic devices is strongly motivated as the reliance on AI-models increases.

  3. 2. CSR communication and the use of recycled synthetic fibres in the fashion industry: A content analysis study of two Swedish fashion brands

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning; Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Linn Löfling; [2023]
    Nyckelord :recycled synthetic fibres; fast fashion; slow fashion; CSR communication; Earth and Environmental Sciences;

    Sammanfattning : The fashion industry is one of the largest contributors to environmental issues and has a significant part of plastic production due to the use of synthetic fibres. Much scientific research indicates that the fast fashion model is a significant part of using synthetic fibres; however, slow fashion brands are also using the fibres. LÄS MER

  4. 3. Hållbara transporter och GRI 305 : En komparativ studie gällande huruvida företag inom olika branscher hållbarhetsrapporterar hållbara transporter och GRI 305

    Magister-uppsats, Linnéuniversitetet/Institutionen för management (MAN)

    Författare :Anna Bodenäs; Ossian Fröslev; [2023]
    Nyckelord :Sustainable transport; transport management; distribution network; means of transport; GRI; sustainability reports; Hållbara transporter; transport management; distributionsnätverk; transportmedel; GRI; hållbarhetsrapporter;

    Sammanfattning : Background: Sustainability reporting has developed due to an increased societal awareness of issues such as climate change. The most used framework in the world is Global Reporting Initiative (GRI) for sustainability reporting. The GRI 305 standard is a part of the framework and its focus area is reporting emission.

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

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Anna Wagne; [2023]
    Nyckelord :Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

    Sammanfattning : 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. LÄS MER

  7. 5. Ett pantsystem för hushållsförpackningar : Potential och kriterier för utformning

    Kandidat-uppsats, Linnéuniversitetet/Institutionen för biologi och miljö (BOM)

    Författare :Madelene Berg; [2023]
    Nyckelord :;

    Sammanfattning : Why do consumers not recycle their packaging? And what is packaging? Plastic and paper packaging have a low recycling rate compared to metal and glass packaging. According to Swedish legislation, a larger amount of household packaging should be recycled. It may also be difficult to determine what a packaging is actually made of. LÄS MER
