1. Investigating Brønsted Acidic Deep Eutectic Solvents for Recycling of Lithium Cobalt Oxide
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/StrukturkemiSammanfattning : Recently, the production of lithium-ion batteries (LIB) has grown rapidly, highlighting the need for efficient and environmentally friendly recycling of LIB waste. In this work, the usage of so-called deep eutectic solvents (DESs) for the leaching of the LIB cathode material lithium cobaltoxide is investigated. LÄS MER
2. Recycling of Textile and Plastic from an Interior Vehicle Component
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : På grund av den rådande klimatförändringen och de globala problem som plast orsakar i miljön blir det allt viktigare att dagens linjära materialanvändning ändras till en cirkulär användning. Inom fordonsindustrin har kravet på ökad tillgänglighet och kvalitet på återvunna material identifierats. LÄS MER
3. Microscopy techniques for studying polymer-polymer blends
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : Semiconductors are used in many electronic applications, for example diodes, solar cells and transistors. Typically, semiconductors are inorganic materials, such as silicon and gallium arsenide, but lately more research and development has been devoted to organic semiconductors, for example semiconducting polymers.

4. Creating nanopatterned polymer films for use in light-emitting electrochemical cells
Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysikSammanfattning : Thermal nanoimprint lithography (T-NIL) is a cheap and fast technique to produce nanopatterns in polymeric materials. It creates these patterns by pressing a stamp down into a polymer film that has been heated above its glass transition temperature. LÄS MER
5. Polymeric single Li+-ion conductors: preparation and characterisation
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Lithium-ion batteries are a common type of light-weight, rechargeable batteries. There are safety concerns because these batteries typically use an organic solvent electrolyte which presents fire hazards. By using dry polymer electrolytes, the fire hazards can be eliminated.
