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. Thermal Conversion of Cellulose-Lignin Precursors into Carbon Fibres

   University essay from Uppsala universitet/Nanoteknologi och funktionella material

   Author : Sofia Westberg; [2023]
   Keywords : Carbon fiber; lignin; cellulose; continuous conversion;

   Abstract : Carbon fibres are used in many applications thanks to their exceptional tensile properties in relation to their relatively low weight. These thin strands of at least 90% carbon are mixed with a matrix such as epoxy to form composites used for cars, wind turbines, prosthetics, and many other things. READ MORE

4. 3. Space-Division-Multiplexing Platform for a Delayed-Choice Experiment

   University essay from Linköpings universitet/Informationskodning

   Author : Hilma Karlsson; [2023]
   Keywords : Wheeler s delayed choice; wave-particle delayed choice; Sagnac interferometer; Mach-Zehnder interferometer; complementarity relation; spatial modes; space-division-multiplexing; LP-modes; few-mode fibers; quantum communication; quantum optics;

   Abstract : This master’s thesis explores a space-division-multiplexing (SDM) platform fora delayed-choice experiment. SDM is a multiplexing technique for optical datatransmission that employs spatial modes in a multi- or few-mode fiber to increasethe transmission capacity. The spatial modes can thus be used as separate channels. READ MORE

5. 4. Quantum Espionage

   University essay from KTH/Tillämpad fysik

   Author : Carlo Ninic Svensson; [2023]
   Keywords : Quantum Nano Photonics; SNSPD; OTDR; Nano Kvantfotonik; SNSPD; OTDR;

   Abstract : This thesis investigates the security of optical fiber communication and demonstrates the feasibility of eavesdropping using different tapping methods and superconducting nanowire single-photon detectors (SNSPDs). Methods for surveillance against fiber intrusion are also investigated. READ MORE

6. 5. Quality enhancement of time-resolved computed tomography scans with cycleGAN

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

   Author : Johannes Stubbe; [2023]
   Keywords : carbon fibers; carbon fibres; microfibers; tomography; deep learning; cycleGAN; time-resolved tomography; Physics and Astronomy;

   Abstract : Time-resolved x-ray tomography enables us to dynamically and non-destructively study the interior of a specimen. The obtainable temporal resolution is limited by the x-ray flux and the desired spatial resolution. READ MORE
