  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. Active dielectrophoretic trapping for deterministic single-cell encapsulation in droplet microfluidics

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Prasanna Surana; [2023]
    Nyckelord :negative dielectrophoresis; droplet microfluidics; low conductivity medium; cell viability; COMSOL electric field simulation; joule heating; Rhodamine B temperature measurement; microfluidic chip cleaning; negativ dielektrofores; droppmikrofluidik; medium med låg konduktivitet; cellviabilitet; COMSOL elektrisk fältsimulering; jouleuppvärmning; Rhodamine B temperaturmätning; mikrofluidisk chiprengöring;

    Sammanfattning : The research work focuses on optimizing various parameters for controlling cells using negative dielectrophoresis and entrapping them in droplet microfluidics. This is achieved by developing a conductivity medium, combining CytoRecovery, BSA, and EDTA, to maintain a steady count of single cells with good viability over an extended period. LÄS MER

  4. 3. The Influences on the Optical Properties of Paperboard Due to Dye Additives

    Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Tanya Wallmon; [2019]
    Nyckelord :White water; buildup; polymer; dye; CIELAB;

    Sammanfattning : In the paper industry the appearance and optical performance of coated and uncoated paperboard is important, therefore colour dyes are widely used to enhance the paperboard. In order to enhance the appearance of paper products, the dyes are added directly into the pulp and/or in the coating. LÄS MER

  5. 4. Urtica dioica, a weed with many possibilities

    Kandidat-uppsats, SLU/Department of Molecular Sciences

    Författare :Johanna Ankarcrona; [2019]
    Nyckelord :Urtica dioica; quercetin; 5-O-caffeoylquinic acid; β-sitosterol; nitrate; phenolic compounds;

    Sammanfattning : The aim of this study was to investigate the nutritional value of Urtica dioica and suggest the application of U. dioica as part of a healthy diet. U. dioica, or commonly known as stinging nettle, is a perennial plant growing almost all over the world. LÄS MER

  7. 5. Heteroleptic Copper (I) Complexes as Photosensitizers in Dye-Sensitized Solar Cells

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Angela Raffaella Pia Pizzichetti; [2019]
    Nyckelord :Dye-Sensitized Solar Cells; Chemical and Environmental Engineering; Photovoltaic; Copper I complexes;

    Sammanfattning : Modern civilization highly depends on energy and finding alternative sources to fossil fuels becomes more and more necessary. The sun is the most abundant energy source available and exploiting it efficiently would result in a great environmental and economic breakthrough. LÄS MER
