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

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

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

    Sammanfattning : 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. LÄS MER

  4. 3. Microstructure characteristics and tribological behaviour of plasma sprayed ceramic coatings

    Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Luigi Fadini; [2023]
    Nyckelord :Thermal spray; APS; SPS; tribology; wear resistant ceramic coatings;

    Sammanfattning : Surface engineering is increasingly becoming inevitable for meeting the high-performance requirements constantly expected from modern engineering components. Higher demands for combined functionalities, which a base material alone cannot provide, motivate intensive academic studies on various types of coatings, with the ultimate objective of their practical utilisation in industries.

  5. 4. Semiconducting TiO2 for High Performance Ferroelectric Tunnel Junctions

    M1-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Erik Wikare; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The ferroelectric tunnel junction FTJ is a rather old concept but has recently been in the spotlight for its promising properties in computer memory technology and neuromorphic computing. The device consists of a ferroelectric insulator sandwiched between two electrodes, and by polarisation switching the resistance along the heterostructure can drastically be adjusted. LÄS MER

  7. 5. Long-term Nitrogen Deposition and Recovery of Epiphytic Lichens : Concealed memory and implications

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Camille Volle; [2022]
    Nyckelord :epiphytic lichens; N deposition; boreal forest; recovery; critical load;

    Sammanfattning : Anthropogenic activities have increased nitrogen (N) emissions. However, higher N deposition is associated with negative fallouts in ecosystems, highlighting the necessity to define its critical load (CLO). Lichens, with their lack of roots, stomata, and cuticles, are helpful air pollution indicators and can be used to establish N CLO. LÄS MER
