1. The transition of reaction-to-fire behavior from biomass to corresponding biochar
Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurserSammanfattning : As of now, the environmental issue is very topical and there is also an underutilization of different biological material where these can be used in ways that are typically not thought of. One way to increase the degree of utilization is to convert various biomasses such as natural rubber, olive pits, wood chips, and reed pellets into biochar. LÄS MER
2. Bio-based resins for digital light processing : Mechanical and degradable properties
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : Thermosets are appropriate materials for various applications due to benefits such as heat resistance and good mechanical properties. The disadvantages of traditional thermosets from a sustainable manufacturing perspective are that they are usually derived from fossil resources, and also have permanent cross-linked networks that are difficult to break, making them non-recyclable.

3. Biobased Photocurable Resins for 3D-Printing of Self-Healable & Recyclable Thermosets
Kandidat-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Överkonsumtionen av engångsartiklar i fossilbaserad plast är ett av dagens stora miljöproblem. Således finns en efterfrågan på strategier för framställning av biobaserade plaster i allmänhet och härdplaster i synnerhet. LÄS MER
4. Injectable and shape-retaining collagen hydrogel, crosslinked using bio-orthogonal cycloaddition chemistry
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Under senaste decennierna, har intresset kring implantat från naturliga och syntetiska polymerer ökat markant i samband med en ökad marknadsefterfrågan på vävnadsdonationer. Detta har lett till efterforskningen av nya in-situ formerande geler med formbevarande egenskaper in-vivo. LÄS MER
5. Development of covalent organic frameworks for energy storage applications : DAAQ-TFP COF and MXene composite electrodes for proton cycling
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Nanoteknologi och funktionella materialSammanfattning : The demand for today's material resources for energy storage is rapidly increasing and can result in both environmental and political conflicts that can affect the development of electronic devices due to high prices and limitations of raw materials for batteries. In this study, potential future composite electrodes were synthesised with an ex-situ approach by compositing redox-active 2,6-Diaminoanthraquinone and 1,3,5-Triformylphloroglucinol covalent organic framework (DAAQ-TFP COF) with conductive delaminated Ti3C2Tx MXene to maximise the number of redox-active moieties during cycling.
