1. 1. Exploring the materiality of ornithopters

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

   Author : Constantinos Makris; [2023]
   Keywords : ornithopters; drones; soma-design; bio-inspired robots; HCI; HDI; ornithoptrar; drönare; soma-design; bioinspirerade robotar; HCI; HDI;

   Abstract : A plethora of multi-copter drones can be found in a variety of public and private sectors in society; crime detection, border guard, agricultural inspections, aerial photography, cinematography, television, and entertainment. Unlike commercial drones, ornithopters - flapping bird-like drones - have a very different materiality. READ MORE

3. 2. Characterization of PLA Nanoplastics, and Their Effects on Daphnia magna

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Melinda Rydberg; [2022]
   Keywords : Polylactic acid; Polylactide; PLA; Nanoplastic; Daphnia magna; Toxicity; Polymer Technology; Chemistry; Earth and Environmental Sciences;

   Abstract : As plastic pollution in aquatic environments keeps happening it has become more and more important to learn more about nanoparticles. Bio-based and biologically degradable plastics, such as polylactic acid (PLA), are gaining popularity and it is therefore important to determine whether they break down into nanoplastics or not.

4. 3. Enhancing the degradation rate of microplastics and organizing a study visit about sustainability

   University essay from KTH/Lärande

   Author : Marianne Al-Ghorabi; [2020]
   Keywords : Accommodation; assimilation; Fenton reaction; microplastics; polypropylene; polystyrene; proximal development zone; study visit; visible light photocatalysis; zinc oxide nanorods; Ackommodation; assimilation; den proximala utvecklingszonen; Fenton reaktion; fotokatalys med synligt ljus; mikroplast; polypropalen; polystyren; studiebesök; zinkoxid nanorör.;

   Abstract : Microplastics take hundreds to thousands of years to degrade in nature, and pose a threat to the environment. A photocatalytical degradation method have been developed to take advantage of solar light to degrade microplastics, however it takes several months to degrade microplastics with the process.

5. 4. 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

6. 5. 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
