1. Sustainable Polymer Production: Investigating Synthesis and Copolymerization of Cyclic Ketene Acetals
Kandidat-uppsats, KTH/KemiteknikSammanfattning : The large amount of non-degradable plastic waste has become a significant environmental concern, leading to an increased need for degradable plastics. Here in, to create degradable polymers, polyesters were produced through radical ring opening polymerization using cyclic ketene acetals. LÄS MER
2. The Potential Use of Degradable Starch Microspheres as a Carrier for Nasal Drug Administration
Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)Sammanfattning : Intranasal drug delivery is a practical and accessible method for treating localized symptoms as well as achieving systemic drug absorption. The approach takes advantage of the permeability, vascularization, and limited enzymatic activity of nasal tissue, leading to enhanced drug absorption. LÄS MER
3. Production of polymers from a papermills wastewater using HTC substrate. : Investigating the viability of using wastewater sludge from Skoghalls’ papermill in combination with filtrate from HTC of sewage sludge to produce biological plastic producing polymers.
Kandidat-uppsats, Karlstads universitet/Avdelningen för energi-, miljö- och byggteknikSammanfattning : Since their conception, plastics have been a dominant product due to the versatility of use, and readily available raw materials. However, the production and consumption of synthetic plastics have continued to increase over the years, leading to a significant rise in plastic waste and its associated environmental impacts, such as the detrimental effects plastic waste has on ecosystems, including the presence of toxic microplastics and risks to marine life, are becoming the focus of criticism.

4. 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.

5. 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
