21. Banning Plastic Straw by Straw: Why California needs a more harmonized approach to plastics management
Master-uppsats, Lunds universitet/Internationella miljöinstitutetSammanfattning : Over 150 local communities in California have implemented plastic product bans as a way to decrease stress on landfills, reduce non-recyclable materials, and manage litter. Plastic product bans such as plastic bags, polystyrene, or single-use plastics, are used to address both local (e.g. litter reduction or community aesthetics), and global (e. LÄS MER
22. Characterization of Magneto-Dielectric Materials for Microwave Devices
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronikSammanfattning : There is an increasing interest in using new composite materials in microwave devices, to reduce size and weight while maintaining similar performances. A new promising material group is named magneto-dielectric materials, which have the permittivity and permeability values both larger than one. LÄS MER
23. Enhancing the degradation rate of microplastics and organizing a study visit about sustainability
Uppsats för yrkesexamina på avancerad nivå, KTH/LärandeSammanfattning : 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. LÄS MER
24. Life Cycle Analysis of three polystyrene waste scenarios : Biodegradation by mealworms as an alternative to incineration or recycling of polystyrene waste?
Kandidat-uppsats, Mittuniversitetet/Institutionen för ekoteknik- och hållbart byggandeSammanfattning : In this research three waste scenario’s for polystyrene plastic are analysed and compared from an environmental perspective. Incineration, recycling and biodegradation by mealworms (Tenebrio Monitor Linnaeus) of polystyrene are to be compared through a gate to grave Life Cycle Analysis. LÄS MER
25. Development and 3D Printing of Intrinsically Stretchable Materials for Microsupercapacitors
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : 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. LÄS MER
