1. 21. Development and 3D Printing of Intrinsically Stretchable Materials for Microsupercapacitors

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Alexander Engman; [2020]
   Keywords : Stretchable electronics; Printed electronics; 3D printing; Direct Ink Writing; Additive manufacturing; Printed supercapacitor; Sträckbar elektronik; Tryckt elektronik; Friformsframställning; Direct InkWriting; Additiv tillverkning; Tryckt superkondensator;

   Abstract : The purpose of this thesis is to develop a simple Direct Ink Writing (DIW) method for fabricating intrinsically stretchable microsupercapacitors as ef- fective on-chip energy storage devices for the emerging stretchable electron- ics. Using the printing method for fabricating intrinsically stretchable elec- tronic components remains a novel approach. READ MORE

3. 22. Photodegradation of macroplastics to microplastics : A laboratory study on common litter found in urban areas

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Jonathan Svedin; [2020]
   Keywords : ;

   Abstract : During the last 60 years the plastic production has increased more than 190 times and plasticpollution both at sea and land is a growing issue. Every year millions of tons of plastic waste fromland reaches the oceans, but the land-based sources are diffuse. READ MORE

4. 23. Impacts on recyclability and sustainability in hanger production by replacing polystyrene with the biocomposite DuraSense® Pure S40 Impact D

   University essay from Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

   Author : Luisa Fernanda Santiesteban García; [2020]
   Keywords : Gabi Envision; LCA; wood fibers; moulding; biocomposite;

   Abstract : Biocomposites have gained increasing attention in recent years. The environmental impacts of common plastics have led researchers and industrials to develop alternatives to fully petro-sourced materials (Beigbeder et al., 2019). READ MORE

5. 24. Adoption of Sustainable Packaging Solutions for the Fish Industry : A case study on a corrugated cardboard packaging solution for fresh fish

   University essay from KTH/Skolan för industriell teknik och management (ITM)

   Author : Andreas Kopp; Robin Falconer; [2020]
   Keywords : Fish industry; sustainable packaging; EPS; corrugated cardboard; diffusion of innovation; innovation adoption; sustainability; Fiskindustrin; hållbara förpackningar; EPS; wellpapp; innovationsspridning; innovationsadoption; hållbarhet;

   Abstract : The rapid development of plastic production the last couple of decades has led to extensive use of plastic products and vast problems with littering, waste management and exploitation of natural resources. Due to the cheap and easy production of plastics, the world’s population has extended the limit of acceptable usage. READ MORE

6. 25. Improving cell secretome analysis and bacteria evolution by means of acoustophoresis

   University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Author : Moritz Leuthner; [2020]
   Keywords : acoustophoresis; acoustofluidic; lab-on-a-chip; acoustic streaming; acoustic radiation force; particle trapping; particle washing; bulk acoustic waves; BAW; media exchange; cell manipulation;

   Abstract : In both, cell secretome analysis and bacteria evolution, controlled handling of particles with a few to sub-micrometers in size and media exchange are inevitable in order to investigate body fluid’s proteins or change the surrounding culture conditions for pivoted evolution. Typically, nanofiltration and ultra-centrifugation are employed which can lead to cell damage, need large sample volumes and have a high sample loss. READ MORE
