1. 16. Synthesis and characterization of lactic acid-based elastomers

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

   Författare :Afsaneh Makhdoumi; [2023]
   Nyckelord :Lactic acid; Elastomer; Bio-based elastomer; Renewable resource;

   Sammanfattning : Synthesized polymer from bio-based and renewable resources reported as an attractive substitution for fossil-fuel based polymers. Therefore, this work has focused on using sustainable material for production of elastomers to reduce the environmental impact of fossil-based elastomers and overcome the shortage of non-renewable fuels.

   Nyckelord :Swedish wool; coarse wool; woven upholstery fabric; textile value chain; sustainability; circularity; fiber characterization; quality testing.; Svensk ull; grov ull; vävda möbeltyger; textil värdekedja; hållbarhet; cirkularitet; fiberkarakterisering; kvalitetstestning.;

   Sammanfattning : Syntetiska material står idag för merparten av produktionskedjan för textilmaterial globalt. Behovet av biobaserade regenererade fibrer ligger i framkant när det gäller framtida val för produktion av textilmaterial i samband med målen för hållbar utveckling. LÄS MER

4. 18. Towards Affordable Sodium-Ion Batteries : Mechanochemical Synthesis and Electrochemical Assessment of Iron-Based Fluorophosphate Cathode Material

   Master-uppsats, KTH/Materialvetenskap

   Författare :Ratna Juwita; [2023]
   Nyckelord :Sodium-ion batteries; electrical energy storage EES ; iron oxide; positive electrode; material characterization; electrochemical; discharge capacity.; Natriumjonbatterier; elektrisk energilagring EES ; järnoxid; positiv elektrod; materialkarakterisering; elektrokemisk; urladdningskapacitet;

   Sammanfattning : An urgent transformation from fossil fuels to cleaner energy sources to combat climate change has led to the utilization of renewable energies like solar, wind, and tidal power. However, the intermittency of these sources hinders their wider implementation. To address this, large-scale electrical energy storage (EES) systems are needed. LÄS MER

5. 19. Size effect in wood : Characterization of mechanical properties using digital image correlation method

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Tillämpad mekanik

   Författare :Amir Saeidi; Olafur Johannsson; [2023]
   Nyckelord :compression test longitudinal direction; digital image corre- lation DIC ; ncorr; phyton; pinewood; size effect; stiffness matrix; wood- construction; YAWCAM; young’s modulus; digital image correlation DIC ; elasticitetsmodul; furu; kom- pressionstest längs fiberriktning; ncorr; phyton; storlekseffekt; styvhetsma- tris; trä-konstruktion; YAWCAM;

   Sammanfattning : As a natural composite material, wood exhibits complex structural char-acteristics and diverse behavior under compression and tensile forces. Itsanisotropic nature results in mechanical properties that vary depending onthe load direction along its longitudinal, tangential, and radial grains. LÄS MER

7. 20. Application of electrodes with redox mechanisms for the desalination of water

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Pablo Moreno Cerezo; [2023]
   Nyckelord :Activated Carbon Cloth ACC ; Capacitive Deionization CDI ; Cyclic Voltammetry CV ; Electrochemistry; Polyaniline PANI ; Prussian Blue PB and Redox Reactions; Aktivt koltyg ACC ; Kapacitiv avjonisering CDI ; Cyklisk voltammetri CV ; Elektrokemi; Polyanilin PANI ; Preussisk blå PB och Redoxreaktioner;

   Sammanfattning : Capacitive deionization is a promising technology for purification and desalination of brackish water with great advantages over current technologies due to its low operating cost and high-water recovery ratio. Most of the system studied relies on the adsorption/desorption capacity of activated carbon electrodes due to its high surface area. LÄS MER
