1. 1. Decay Chains of Fast Alpha Emitters in the Actinide Region

   Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysik

   Författare :Tanvir Sayed; [2024]
   Nyckelord :alpha decay; alpha emissions; fine structure; decay chain; decay scheme; alpha spectrometry; actinide; nucleus; nuclear structure; nuclear states; energy levels; uranium isotopes; U310 experiment; parasitic runs; decay station; TASISpec ; moving window deconvolution; digitisers; alpha-gamma coincidence; 221-Th decay; fine structure of alpha decay to 217-Ra; GSI; Gamow s theory; Geiger-Nuttall; chain search; short half-lives; Physics and Astronomy;

   Sammanfattning : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. LÄS MER

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

   Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

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

   Sammanfattning : 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. LÄS MER

4. 3. Beständigheten hos brandimpregnerat trä

   Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

   Författare :Filip Engström; Hannes Psajd; [2024]
   Nyckelord :Fire retardant treated wood; ISO 5660–1; Permanence; Euroclass; Cone Calorimeter; ConeTools; Infrared spectroscopy; Technology and Engineering;

   Sammanfattning : This report explores the properties of fire-retardant treated wood. This report has investigated the permanence for this material as well as seeing if the process of accelerated aging, which are used to determine the life span of the material, can be comparable to natural aging.

5. 4. Tillämpning av additiv tillverkning för framtagning av ett hållfast formsprutningsverktyg

   Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

   Författare :Ahmed Najaf; JR Pezo Salas; [2024]
   Nyckelord :Formsprutning; SLA; 3D-printning; Additiv tillverkning; Resin; CAD; Gjutform; Optimering; Produktutveckling; Konstruktion; Design.;

   Sammanfattning : Introduction: Additive manufacturing (AT) also known as 3D printing has become a more widespread technology in various industries. The manufacturing method has increased the efficiency of manufacturing industries in producing products with technically challenging properties. LÄS MER

7. 5. Evaluation of different block-copolymer coatings of iron oxide nanoparticles by flash nanoprecipitation

   Master-uppsats, KTH/Fiber- och polymerteknologi

   Författare :Felix Bogdan; [2023]
   Nyckelord :Nanopartiklar; organisk katalysator; ROP; block-sampolymerer PL G A; oljesyra IONPs; Nanoparticles; organic catalyst; ROP; block-copolymers PL G A; oleic acid IONPs;

   Sammanfattning : Nanopartiklar (NP) erbjuder unika möjligheter för medicinska tillämpningar, inklusive kontrollerad frisättning av cancerläkemedel, användning som bildkontrast vid avbildningsprocedurer eller hypertermisk behandling av cancerceller. Flash nanoprecipitation (FNP) producerar NPs för att kombinera dessa tillämpningar i en snabb, billig och skalbar beläggningsprocess. LÄS MER
