  1. 1. Virtual H&E Staining Using PLS Microscopy and Neural Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Sally Vizins; Hanna Råhnängen; [2024]
    Nyckelord :Deep learning; Virtual staining; Skin tissue; Hematoxylin Eosin; H E; Pathology; Carcinoma; Point light source illumination; Neural Networks; GANs; Generative adversarial networks; CNNs; Convolutional neural networks; Relativistic generative adversarial network; Unet; Digital microscopy; Attention-Unet; Dense-Unet; Mathematics and Statistics;

    Sammanfattning : Histopathological examination, crucial in diagnosing diseases such as cancer, traditionally relies on time- and resource-consuming, poorly standardized chemical staining for tissue visualization. This thesis presents a novel digital alternative using generative neural networks and a point light source (PLS) microscope to transform unstained skin tissue images into their stained counterparts.

  3. 2. Real- and Quasi-Atomic Layer Etching for Ultra-High Resolution Patterning

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Yoana Ilarionova; [2023]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : An attempt was made at developing atomic layer etching from a cyclic etching process in an ICP-RIE tool. During the process OES was used for contamination monitoring and estimation of the relative amount of Cl2 left in the chamber during the etch step of cyclic etching processes. LÄS MER

  4. 3. Lignin Biorefining: Swelling and activation of fibers for lignin extraction

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Ali Al Husseinat; [2023]
    Nyckelord :Biorefining; Carboxymethylation; Extraction; Lignin; Swelling; Bioraffinering; Extraktion; Karboxymetylering; Lignin; Svällning;

    Sammanfattning : I världens omvandling mot en bioekonomi kommer lignocellulosa material spela en stor roll i ersättningen av fossila resurser. Lignin är den mest tillgängliga källan av förnybara och naturligt förekommande aromatiska ämne och den utgör 15–30% av ved. LÄS MER

  5. 4. Kvantkemisk förutsägelse av regioselektivitet och reaktivitet hos SNAr-reaktioner

    Kandidat-uppsats, KTH/Kemiteknik

    Författare :Elias Norstedt; Gunnar Åkerlind; Fredrik Robin; Olof De Verdier; [2023]
    Nyckelord :Kvantkemi; teoretisk kemi; SNAr reaktioner; aromatisk substitution; nukleofil; reaktivitet; regioselektivitet; modell; förutsägelse; lämnande grupp; klorid; bromid; fluorid;

    Sammanfattning : Multivariate regression of several different quantum chemical descriptors was used to build a model for the reactivity of nucleophilic aromatic substitution reactions, i.e. SNAr reactions, through predictingthe molecular reaction site’s Gibb’s free activation energy (ΔG‡).

  7. 5. Define optimum process conditions to produce CO2 adsorbents from pur materials

    M1-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Daniel Pantzar; Anton Coates; [2022]
    Nyckelord :Carbon capture and storage; Adsorbent; Chemical activation;

    Sammanfattning : The Carbon Capture and Storage method has been acknowledged for the capabilities of reducing up to 20% CO2 emissions. Development of porous carbon materials prepared from polyurethane foam adsorbent were investigated for capture of CO2. In this thesis work, the carbon material was chemically activated through the direct and indirect methods. LÄS MER
