1. 1. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

   University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

   Author : Grigore-Leon Ratiu; [2024]
   Keywords : Physics and Astronomy;

   Abstract : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. READ MORE

3. 2. Techno-Economic Analysis of Dye Separation in Textile Recycling

   University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

   Author : David Lundberg; [2024]
   Keywords : Dye; Membrane filtration; Electrocoagulation; Techno-economic analysis; Pre-feasibility study; Technology and Engineering;

   Abstract : This study determines the technical and economic feasibility of separating dye from a process filtrate in industrial textile recycling using electrocoagulation or sequences of membrane filtration with microfiltration, ultrafiltration, nanofiltration and reverse osmosis. The lower requirements for treating this stream, compared to previously researched dyehouse effluents, left treatments not good enough for dyehouses viable for this process filtrate. READ MORE

4. 3. Gas Chromatographic Method Development for Analysis of Samples from a Carbon Capture Pilot Plant

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : David Wedin; [2024]
   Keywords : Carbon Capture and Storage; CCS; AMP DMSO; Gas Chromatography; amine absorption; analysis method development; Chemical Engineering; Chemistry;

   Abstract : In response to the escalating threat of climate change, carbon capture and storage have gained increasing attention as an important component in mitigating the global carbon dioxide emissions. Substantial research efforts have focused on enhancing the energy efficiency and availability of these technologies. READ MORE

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

   University essay from Lunds universitet/Matematik LTH

   Author : Sally Vizins; Hanna Råhnängen; [2024]
   Keywords : 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;

   Abstract : 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.

6. 5. Prospects for standardisation of industrial PET plastics to support the transition towards a circular economy

   University essay from Lunds universitet/Miljö- och energisystem

   Author : Agnes Ström; [2024]
   Keywords : Standard; standardisation; industrial PET; polyethylene terephthalate; circular economy; plastic; Technology and Engineering;

   Abstract : Plastkonsumtionen har ökat markant över tid och har utvecklats till ett viktigt material i dagens samhälle, men med utmaningen att råvaran främst kommer från fossila källor. Användningen av plast är i linje med den linjära ekonomin och den så kallade slit-och-släng-kulturen, vilket bidrar till felaktig hantering av plastavfall och en ineffektiv användning av resurser.
