3. 12. A study of the triboelectricity of 2D materials: MoS2, WS2 and MoO3 : Analyzing measurements from a triboelectric nanogenerator

   Kandidat-uppsats, Mittuniversitetet/Institutionen för naturvetenskap

   Författare :Simon Kilman; [2022]
   Nyckelord :2D-material; MoS2; WS2; MoO3; triboelektrisk nanogenerator; TENG; triboelektrisk effekt; triboelektrisk serie; kontaktelektrifiering.;

   Sammanfattning : Detta projekts mål har varit att undersöka tre olika 2D-materials triboelektriska egenskaper och därmed placera dem i en triboelektrisk serie. Detta utfördes genom att använda en triboelektrisk nanogenerator (TENG) och mäta den resulterande spänningen. Tio stycken motmaterial applicerades mot varje 2D-material på nanogeneratorn. LÄS MER

4. 13. Tribology of Polymer Composite with Low Load Application for Automotive Industries

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Martin Asuquo; [2022]
   Nyckelord :;

   Sammanfattning : In recent times, there has been an increased interest in replacing conventional metals and synthetic fiber composites in various automobile parts with natural fiber polymer composites. These natural fiber composites offer benefits over conventional materials in terms of reduction in weight, lower cost, comparable high specific properties such as specific stiffness and strength, low abrasion property, and availability of these materials.

5. 14. Den vertikala trädgårdens utveckling : En design research studie för framtagning av ett teoretiskt väggsnitt bestående av en halvsandwich med en infäst levande fasad

   Kandidat-uppsats, Jönköping University

   Författare :Johanna Backnäs; Lisa Svensson; [2022]
   Nyckelord :Carbon dioxide equivalents; cellular plastic; EPD; half sandwich wall; sandwich wall; living façade; Kooltherm; PIR; Cellplast; EPD; halvsandwichelement; helsandwichelement; koldioxidekvivalent; Kooltherm; levande fasad; PIR;

   Sammanfattning : Introduction: There is a housing shortage in Sweden and the green space factor must be taken into account when building. The green space factor includes living façades that have a positive effect on people and society. The company Butong, in which the work has been done in collaboration, has patented solutions within living façades. LÄS MER

7. 15. Removal Characteristics of Fibrous and Particulate Microplastics : A Study of the Effectiveness of Coagulation-Flocculation- Sedimentation

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Amrith Kumar; [2022]
   Nyckelord :Coagulation; flocculation; jar test; microplastics; sedimentation; water treatment; Burktest; flockning; koagulering; mikroplaster; sedimentering; vattenrening;

   Sammanfattning : The rapid proliferation of microplastics (MPs) over the last few decades have raised alarms about the major environmental and health impacts posed by this anthropogenic source. The widespread propagation and transport of MP particles in water sources have accelerated the need to study the eco- toxicological impacts as well as the efficacy of various removal mechanisms from these critical water sources.
