1. 1. 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

3. 2. 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

4. 3. Microbial production of chemical building blocks from lignin

   University essay from Lunds universitet/Teknisk mikrobiologi

   Author : Kevin Bertilsson; [2024]
   Keywords : Lignin; Green plastic; Vanillin; Microbial production; Applied microbiology; Biology and Life Sciences;

   Abstract : Plastics, derived from fossil fuels, have raised considerable environmental concerns. This has prompted the search for sustainable and safer plastic precursors alternatives. One alternative explored in the present study is vanillin, a phenolic compound derived from lignin, an abundant and renewable natural polymer. READ MORE

5. 4. Sustainable food packaging based on polyhydroxyalkanoate

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Safana Al-Ashor; [2024]
   Keywords : Biopolymers; Sustainable food packaging; Circular economy; Biobased and biodegradable materials; Food packaging; Processing technologies; Food quality; Shelf-life;

   Abstract : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. READ MORE

6. 5. 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.
